Hello and thank you so much for your help. You went into great detail. What I'm wondering is, when I switch from XLR to XLR/RCA, my preamplifier should be driven with 5.2 volts, right? Or when switching from RCA to XLR, the Eversolo should output different voltages – correct? For me, the music volume remains constant. How is it for you? My preamplifier has an gain control of 11dB to 28dB. I had an idea yesterday. Could it be that the Eversolo is adjusting its output signal? I set my preamplifier to 11dB gain – actually, the signal isn't being amplified now. The signal goes to the power amp without any amplification. The Eversolo was reset. After the reset, I played music through the Eversolo and adjusted the volume control to -100dB and then to 0dB. After everything was set up again, I set the preamp to 28 dB gain. What I immediately noticed was that the bass in the music was more pronounced. In general, the music is now louder. I can now adjust the gain down to a maximum of -20 dB; beyond that, it gets too loud. What I'm writing seems a bit mysterious to me—I can't see the logical connection. (If I use the room correction ( 0 dB up to 180 Hz - the Schröder frequency) and set the equalizer to 0 dB, the system distorts.) I'm still a bit hesitant to get my hopes up. But my problem is probably solved. I can't really explain why it's like this—it might sound a bit esoteric, but that's how it is.
Hello , this is all very important and very accommodating provided that everyone’s AMPLIFIER has the ability or the capability to be able to select various or different gain level settings or outputs most folks or guys here in my part of the world for whatever reason that type of control is totally nonexistent on most high-end amplifiers that I have seen in my part of the world in the last 40 years, now left and right volume or attenuator somewhere on the AMPLIFIER yes, absolutely very common. I have here a great number of amplifiers naturally due to Bi-Ampping purposes and out of all of them only the Crown amps have left and right output level control controls, which has nothing to do with gain it is merely a level control for the left and right audio output channels. It is not going to make the amp have any more input gain or a higher structure of input in order to receive a greater output the moral of my story be you are very lucky and it’s a wonderful feature to have however, most amplifiers I have came across and decades do not incorporate such features as different gain level input settings. This may not be a bad idea. However, every time gain is increased, you are also increasing other problems along with that increase good day to everyone please enjoy the music
Yes, the DMP-A6 can output up to 2.6vRMS (0dB ref.) from the unbalanced RCA sockets; and up to 5.2vRMS (0dB ref.) from the balanced XLR sockets. This 6dB difference is normal for most equipment featuring both unbalanced and balanced connections. I'm not sure what you mean by "the music volume remains constant". This might require further clarification in order to answer the question. Now I'm really confused. I thought you were feeding the audio out from your DMP-A6 directly to your power amplifier which has switchable gain from 11 to 28dB in steps. I could not find any reference to the preamplifier in the audio chain in your original post, hence the confusion on my part. The DMP-A6 doesn't "adjust its output signal on its own per se. The output level can be adjusted to suit the listener's preferred listing level via its own volume control provided it hasn't been set to a fixed level. Once again this is confusing as there weas no mention of a preamplifier in the audio chain in your original post. Generally pre-amplifiers have a variable gain (or more specifically a variable attenuation i.e. a volume control). Adjusting the gain should not affect the frequency response of an amplifier. The apparent "more bass" is a result of psychoacoustics - Your human hearing response to louder sounds. At low listening levels the hum auditory system is less sensitive to the extremes of the audio spectrum. Your hearing sensitivity drops off at low levels in both the bass and treble areas, however remains sensitive in the mid-range frequencies. Adjusting the gain on what? The DMP-A6 or the amplifier? Sorry, nor can I. This is a common problem with the DMP-A6 EQ or more correctly a misconception on the part of users on how to use the EQ functions correctly. If you add any gain to any frequency of the equalizer or the parametric equalizer you have to adjust the gain setting in the EQ to prevent overload. Here's an example - Your room requires 4.5dB of boost at say 40Hz to compensate for room acoustics. If you simply boost that frequency (as an example) by 4.5dB there is a possibility you might drive the output of the DMP-A6 into distortion when music at that frequency is reproduced if it has been recorded loudly. To compensate for this you need to adjust the EQ GAIN on the DMP-A6 down to -4.5dB to prevent possible overload distortion. A point to bear in mind. By lowering the EQ gain or parametric EQ gain by 4.5dB you will be lowering the output from the DMP-A6 over the entire audio spectrum except at and around the frequency you chose to boost.
The only way this low output gain is absolutely solvable or tolerable 1 of 5 ways as per example below we’ve been through this for probably close to two years now it’s getting ridiculous as listed below 1 of 5 that would be most common to the average AUDIO individual, NOTE , this is a matter of personal opinions and Findings from a small group of individual's experiences Here at listening together, #1. You are using an ultra high set of efficiency speakers of at least 95DB sensitivity, or greater the sensitivity the Absolute higher the better, #2. You are using or employee, the use of an integrated amp which retains a pre-amplifier and an amplifier in one unit known as an integrated amplifier, also works Out extremely nice naturally, depending on the unit #3. you are using or have obtained a decent quality pre-AMPLIFIER be a solid state or tube unit, OR a dedicated AMPLIFIER, tube or solid state with a series of settings or switches, which will Enable you to increase overall gain output in specified increments Or input gain settings, we have one here an old Hafler SS AMP with rear adjustable trim pods But unfortunately, did not work out to our expectations #4 you are using a very nice set or pair of powered loudspeakers commercial or AUDIO file grade. These speakers tend to be highly ultra efficient I have seen some rated at 106 DB in sensitivity # 5. you are 100% and absolutely totally satisfied and are not bothered by the low level or gain output and enjoy the extremely low level drive or performance although overall gain output or drive, which is absolutely wonderful. If you are, you are one of the very few well I would consider you very lucky. Absolutely nothing wrong with that if you are very satisfied, The 4 of us have spent countless evenings in a dedicated listening room, and these are the basic conclusions. We had all arrived at and agreed on after countless hours of trial and error NOTE, absolutely no EQ of any type were used employed or implied all controls as such set to the off positionThe above methods were the most common to the average user or average audio hobbiest, also a buffer gain stage of at least 8 to 10 DB of increased gain output, last and final thought, however, this is just a matter of a few guys opinion that have been doing this for literally decades with an endless list of audio equipment, And never encountered an output Gain level problem as such , however your opinion may be very different and the above quite unacceptable, In which everyone entirely appreciates and respects your own opinion or use of different configurations or hook ups, etc. again this is simply a matter of opinion, everyone here is extremely well aware of all bench test and specifications dictate. However, in the real world use something is way out of bounds, in actual use of these units, we know the output gain specs But have reached absolutely no conclusion to where it is going. It is not going to the output that’s for darn sure. have a beautiful weekend to all and enjoy the music
@Alan Rutlidge , Hello and sorry for the confusion. I'll try to clarify things. My power amplifier is a Class-D NCore NCx500, which has a built-in preamp. The preamp can be deactivated, but then the signal must be 13 volts. I don't quite understand why 2.6 volts and 5.2 volts sound the same. I suspect the voltage is just a carrier signal. In conclusion, I can say that the Eversolo is now playing louder—I'd estimate by about 10 dB. (Previously, my hearing level was between -30 dB and -20 dB. With classical music, it even dropped to 0 dB. That was with 500 watts RMS ;-) . Now it's between -40 dB and a maximum of -20 dB.) Thanks to everyone who helped me!
Whilst you raise valid points there is one glaring problem. I seriously doubt users are going to dump their other system components (which one has to assume are working in perfect harmony and they are completely happy with) for one component that doesn't integrate well with the existing system components. Let's use an example. A customer has a pair of Duntech or Magnapan speakers which have a reputation of very high quality reproduction (other's opinions not mine necessarily) but are notoriously difficult to drive to high SPLs unless you have a pretty powerful amplifier. An investment of tens thousands of dollars and more importantly the customer loves the sound. So, they decide to add a DMP-A6 to the stable, but alas it appears to have a bit too low an output to drive the amplifier and speakers to satisfactory loud levels. What can one do? Decide that the DMP-A6 isn't for them and return it to the dealer for a refund or store credit. On-sell the DMP-A6 if the vendor doesn't have a return policy, it was possibly purchased as a grey import or the return / refund period has lapsed. Consider adding a buffer pre-amp with sufficient gain between the analogue outputs of the DMP-A6 and the next component in the audio chain. Buy an alternative device that works to expectations with the existing system components. IMHO, option 3 is probably the better one if the customer is completely happy with their existing system and doesn't particularly desire to change any of the existing components. IME, this all boils down to either working with a dealer that is knowledgeable about your existing products and can advise on compatibility accordingly or simply agree to refund / give a store credit towards an alternative product should the piece of equipment you just purchased not live up to your expectations. I fully appreciate this isn't an option available to all customers from all vendors.
That's some signal level requirement. I seriously doubt there'd be many devices or pre-amplifiers out there capable of delivering 13v RMS. A typical solid-state preamplifier with an op-amp output stage running from a typical +/- 15v d.c. power wouldn't be capable of delivering the output voltage swing to 13v RMS. Maybe from a discrete device output running at higher supply voltages, but not your typical op-amp types. The signals are in the analogue audio domain. There is no "carrier" per se. In the audio industry standard interface specifications exist but of course can vary from product to product. Where a device offers both balanced as well as unbalanced inputs or outputs there is normally a 2:1 voltage ratio between them respectively. In other words the balanced connection will be twice the voltage level of that of the unbalanced connection. This is because the balanced connection is a differential circuit (+ hot, - hot plus earth or ground shield) whereas the unbalanced is a hot wire which carries the signal with a ground return (shield). So the 5.2v balanced and 2.6v unbalanced outputs from the DMP-A6 are following industry standard practice. So if you hear no volume change when you switch from balanced to unbalanced and vice versa your equipment is following industry standard for these interface types.
Hey hello Al, as I stated many times I am always very happy and look forward to reading all your replies posts and opinions. In my personal opinion. I absolutely do agree with you 100%. also you are absolutely correct years ago. I had a pair of magnapan 3 A’s I certainly agree with you. They were one of the hardest speakers I have ever owned as far as driving them even just to a normal listening level, you are also absolutely correct, I had to New York AUDIO Labs MOSCODE 600’s , 300 watts per ch very nice amps at the time, I Bi ampped , One amp running the bass panels the other running the mid range panel and ribbon Tweeters, These particular models were factory set up to do so if one wished to partake in this type of operation. When I added the second Amp I thought the cloth socks were going to blow off them. They just popped and came to life, but unfortunately, at that particular time back in the late 1980s this was not my favorite type of flavor sonically speaking but a dynamite wonderful speaker I they believe they would still hold their own today to many out there at present . I fully understand in what and how you are explaining You are right on point absolutely, However, unfortunately, I can very honestly tell you I personally know a few folks that very reluctantly sold or parted with their Eversolo unit, regardless of the model or simply due to The very low gain or drive in gain output of these really wonderful Eversolo units I would imagine it was probably the most logical thing to do as it would make or be the most sensible move to part with one piece of equipment no matter how much you liked it instead of changing or figuring out how to get more pusher drive and perhaps wind up changing most or your entire system around, it is really very unfortunate as a few folks I know really loved these units but just could not tolerate the low level gain output or drive. again I imagine this was probably more than likely the most logical move one could make and most likely the easiest, especially do to any type or lack of expendable funds or other circumstances unfortunately, I really like and enjoy my Eversolo A8 and absolutely plan on keeping it for as long as time permits into the future as I stated for which could be anyones guess especially today. Now, perhaps just to make a point and Al , I do belive you know me to some degree. I am not being condescending or facetious , seen some of these folks afterwards had went on and purchased other make models of streamers Ect , and absolutely did not encounter any of these issues, or specific problem’s as such, I myself after countless types of equipment use and ownership I have never ever honestly encountered this particular type of Gain output situation, maybe perhaps In using a passive preamp, through out years ago I was simply stating in my own opinion, along with a few other AUDIO guys here in my part of the world that are way up in years and have been doing this before I entered high school in the 1970s we have one gentleman here that had supervised numerous rock concerts throughout the 70s and was their main tech set up and Audio control guy for all the sound using big JBL‘s & many other speakers that were sitting up there on giant very enormous scaffolds ect, I do believe to a varying degree he does retain alot of knowledge from doing it professionally more than what I know or knew in the past, AL, I am also aware that you yourself are a condoned true professional again enjoy reading your post as I stated many times yes, absolutely there are several avenues you can explore and rectifying this problem as I did myself, but not everyone has the capability of doing so in which is fully understandable but however, no matter how we slice and dice it there is absolutely without doubt a very low gain structure as far as their output, their professional engineering reasoning behind this I have no idea, but it has caused folks a lot of dismay and discontentment in the past now even going into the present with some new members we now have on board as a matter of fact, if you take notice quite a few of the older members aren’t even around anymore and haven’t been for quite some time, a shame their were extremely knowledgeable Forum members, But again the Eversolo’s are wonderful units if you can live with that and our perfectly happy, absolutely no problems but for most people yes it is an absolute problem. This is why when I first addressed this issue I do not know how long Eversolo keeps past forum messages for entries this has been brought up and discussed so many times you could not count, however I most certainly 100% do agree with out further discussion # 03 indeed would be the absolute best option thank you, Al. I am always very happy delighted and even somewhat anxious. I always read your post and I certainly respect your opinion and most certainly always will thank you for your comment and your ideas. Please have a wonderful weekend. Al * Also Please have a wonderful holiday As always, I remain respectfully yours
It is the same level! 2,6V unbalanced is 5.2V balanced. Both the signals have 2,6V to reference. So they give the same sound pressure! It's a technical thing. Don't wonder about it. accept it! There is no direct relation between volume levels and powers. Also stop thinking you have a 500W amplifier. You have an amplifier that can deliverupto 380-700W Watt but that will never happen (i hope for the sake of your speakers and ears)! a normal speaker will give a sound pressure of 85-90dB soundpressure at 1 Watt. The law (Netherlands) demands your employer to suppply sound protection if the sound pressure goes over de 80dB!!!!!!! At average normal listening; An amplifier will give 0.1-5 Watt signal to the speakers.
Hello this has absolutely nothing to do with accepting it. It is not in operation the correct way Let me ask you something please don’t think I am being abrasive or condescending. I am just trying to emphasize the correct nature and cause I don’t believe anyone is actually worried about it with the exception of some folks just not having enough gain or drive output That prevents them from totally enjoying part of the audio system let me ask something I could be wrong, but I’m most certain you probably use our own a big screen television as of today some people don’t, but the overall population more than likely does. if you were viewing your television set and only had one volume output that was quite low and lifeless sounding, but there was an alternative output that would employ a much higher setting as far as volume, gain output. but however, it turned out to be useless, Due to when you went to activate or use the higher level of output that technically speaking was absolutely supposed to help but absolutely made no difference whatsoever I may be wrong, . I don’t actually believe you would say well don’t worry about it. Wright? I’ll just put my ear up to the speakers or turn The volume control just about maxed out in order to hear something or , I’ll just accept it, Well, perhaps some people absolutely would. It’s a strange world, but it’s their opinion. We are absolutely all entitled to our own opinion if that’s your thought I respect it, but it is not correct or proper function. However, best of luck to you have a nice weekend and a very happy holiday. Enjoy the music
You don't have a choice. It is how it is. That is how the industry has intended it. 2,6V unballced and 5,2 Ballanced are supposed to give the same signal to a recieving input. With some trickery you can use to a ballanced output signal on a unballenced input to get twice the amout of signal (only 3dB). But it can also ruin the input! Well i have a AV7704 pre/pro and it is only outputting 1.2V unballenced/rca or 2.4V ballanced XLR wich is more then enough to drive my Class-D to destoying my speakers. It has 3 settings 11.8db, 21.8 or 27.8 dB They are set to 27dB because that comes close to my previous amps. It give the most power at the lowest signal. If these settings cannot drive your set there is a serious setup problem. I wonder if these dB notations are the real confusion. 11dB versus 27dB on the gain settings in the amplifier is the total opposiste of a volume notaion -11dB verssus -27dB There are situations were you could be rigth. But it is a solution to mask an other problem. Why is the sound presure too low? I asure you it is not the difference between balanced or unballanced and feeding XLR into RCA does not improve anything other then 3dB and the risk of an output being misused and therefor not performing correctly! Same, have a good one!
yes I would most certainly say you’re almost correct provided all balanced or XLR/AES connections naturally on both ends of the cable, if and only if your equipment is internally designed and running an electrically engineered, etc., to receive and except a truly balanced circuit designed within the unit from the manufacturer maker or builder, etc., I have often came across in the past I won’t name names of inputs and outputs that accommodate the XLR/AES usable connections however the only problem being is I believe they were put there. Let’s say for sheer convenience purposes But unfortunately the unit or units Do not have or incorporate the truly balanced internal electrical set up and will absolutely make zero difference in any type of higher gain structure or output naturally, when anyone sees a Balanced connection be at input or output you would believe that it’s safe to assume that it is a truly balanced connection not just an input or output, XLR input or output Jack that serves no useful purpose other than being able to accommodate an XLR cable, in which I honestly believe this is truly and somewhat misleading to the average AUDIO consumer I myself have came across this particular situation or scenario more than a few times Best of luck to everyone please enjoy the remainder of the weekend. Happy holiday and enjoy your music
With 28DB of total available gain absolutely and certainly should be more than amble to suffice. If this is your actual set up or situation in which I certainly believe it is, you should absolutely have no problems whatsoever none, I merely increased my output gain externally between 6 and 9DB and so far it has worked out beautifully wonderful quite happy at this present time with the use of the A8, best of luck to you If and only if all that nice equipment that you are using or absolutely without question, a true balanced input and output, as I have stated before, if not, you are merely wasting your time, but you are using an XLR cable If by chance you can take a quick look of what the inside of a truly Balanced UNIT or piece of AUDIO equipment actually looks like or is basically laid out please take a look at a schematic diagram. You will then see major differences, internally, speaking naturally of what a truly balanced circuit actually looks like in looks Somewhat of a major difference compared to RCA or a single end line in our line output or input please have a great day. Everyone enjoy the music.
I have no clue about the total gain. But putting a gain setting to 11dB as oposed to 28dB and then wonder about low soundpresure seems obvious. The bal.vs unbal. is irrelevant to this problem. that would fix only 3dB were the gain setting provides 17dB
Hi no pun intended, but you might want to familiarize yourself with it if you plan to keep up with the AUDIO hobby for future knowledge that could absolutely come in A quite handy as you go into the foreseeable future After your Eversolo UNIT, if you were going into a a device example, preamp, integrated amp, etc. you are 11 DB of gain should be more then adequate Myself I only use 3,6 or 9 DB of gain , 6 usually works out quite well, but you must keep everything in mind. My loudspeakers are ultra high efficient, eight or 10 W if that of total input in my case, and only in my case, with my particular loudspeakers will take the paint off the walls seriously please have a wonderful afternoon whatever part of the world you may be in. Have a wonderful holiday. Enjoy the music
Hi, I have an Eversolo with an external Gustard X16 DAC, the maximum voltage generated by the XLR output is about 4 Volts, my amp is based on an EVAL1 Stereo 1ET400A Evaluation Kit witch is setted at +26 dB gain All is perfect for me, I suggest you to set you amplifieìr ar a +28 dB gain Regards
That’s a hell of a lot of Gain, but if your not distorting, or overloading that’s great, the output signal coming out of and Eversolo of any model or any standard Audio DAC , wow I am absolutely saying that you can’t do it to a varying degree. But that’s a whole lot of drive. While running or using an old pair of acoustats 2+2’s pretty cool loudspeaker I believe the company went out of business many years ago. They had a sensitivity rating of about 82 db sensitivity if memory serves me correctly, but if it works, it works best of luck with that seriously. Using an old AUDIO research preamp, had approximately 16 db of total output gain ,Unbelievable wow you have a great weekend and a wonderful holiday. Enjoy the music.
Hello and thank you for your help. First of all, I have to say that my problem is solved. I hope it stays that way. The Eversolo sounded good, but was much too quiet. It was possible to turn the volume down to 0dB. It was loud, but not up to the technical specifications.
Why do you want us to lower the Gain. I got some reasons to not do so. And some to do it. Why do lower the gain: -better theoretical performance (noiselevel and distortion level drop a little. Here are the specs of a Nilai module, in relation to the gain settings These numbers are cristal clear. For the dmp-a6 as 'pre ampilfier' the high gain is not a strange choice. but it comes with a higher noise distortion numbers. But still lower then the specs of the dmp-a6. -When errounesslye switching to "volume by pass mode" the damage to the speakers/ears is lower. -when switching from stereo to M-ch all dsp functions are bypassed so you get a different output level. Especially DTS has a huge sound pressure. Reason to do increase to high gain: -Some of the amplifiers in your set also have high gain and you want the loudness to match. -You try to run an audyssey measurement on multiple speakers an its needs need to match the gains. -You have all sorts of software dsp settings on (dsp,ARC, replaygain) which seriously decreases the output of the dmp-a6 -You play tracks with low volume. Tracks that are not recorded with the loudness madness in mind. What do you Biamp300B have to add to this list?
