Excluding Bass Management, the sound is almost similar (the difference is due to the different DAC/Op-amp of the soundcard). Using ASIO, the full range/limited range option in drivers/Windows is just ignored (like all the other driver settings). The sound is always sent to each channels as it should ("full range"), then the sound goes into the amplifier that should manage the bass and re-directs the lower frequencies not covered by the satellites to the subwoofer (using ASIO as the output module you can be just sure that both drivers or Windows aren't messing something).
With digital connection and stereo analog (Aux-In/CD-In) this works just fine. The digital and stereo analog have the same amount of bass frequencies and sounds identical (apart the difference in DAC/Op-amp mentioned above). With 5.1 there's a strong lack of bass frequencies. This not only with 2.0 input, but with native 5.1 as well. In 5.1 the subwoofer plays the LFE channel but the lower frequencies coming from satellites are strongly attenuated (if not discarded at all). With 5.1 (Dolby/dts) coming from digital this doesn't happen and the sound plays right.

(Still, nobody contacted me. Let's see if in this week something happens)

Hi, is this really a design flaw? I'm not really agree with you.

From what you mentioned, i believe this is intended design rather than flaw and i can understand the reason behind of such design.

The design is quite clear, if you want the speaker redirect/process internally, send digital signal into it, the built-in DAC and DSP will do the job.

Other than that, if you input multichannel analogue signal in, the speaker will just assume you want to bypass the internal built-in DAC and DSP and fully rely on the analogue signal and only do amplification without processing (or ADC->DSP->DAC which will lead to extra quality loss), so now your sound card is the main DAC/DSP.

Why stereo it will redirect the bass? Because in stereo mode your speaker is actually "2.1", not "2.0", like or dislike you have to let the internal DSP to re-direct bass to sub, simply because you won't be able to find 2.1 setting in your sound card (which can set bass re-direct in stereo mode) i believe.

Hi, sorry but to me it doesn't make any sense.
If this is intended, then it was intended really wrong.

The sound card is not intended to do any bass management. Some sound card allows you to do so, it is an additional feature, but a lot of them doesn't offer this. Also this system is not only specific to "pc world". With analog you can connect it to whatever you want. A set-top bluray player or dvd player with 5.1 analog out will *NEVER* do any bass management. They will output the sound "as is", exactly like a normal sound card. The bass management, for these systems, is supposed to be managed by the speaker manufacturer -Edifier in this case- because it's the only one who built the system and knows how the crossover should be set for each particular speaker. Final user is not supposed to know how to set a bass management, unless we're speaking of high-end speakers where you can set the crossover for each independent speaker.

Also, if you have a pc with only analog out, you can't hear both 5.1 and 2.0 in the right way, unless you always switch back and forth the connections on the back of the subwoofer (insane).

The flaws is in the fact that the sound still passes from some form of processing, even on analog. If not, I would be able to send a full-range audio to a satellite speaker and have the risk to broke something (send a 30Hz frequency on a 2-way satellite...). So "something" is filtering that 30Hz frequency but rather than "redirect" it to the subwoofer (who can play that sound, and this is the right way to intend a crossover), it simply discard it.

Not considering that all the 5.1 amplifiers you can find in the market have the crossover working right and in the same way for both digital and analog input.

Another example... almost all musical dvd/bluray doesn't have a .1 channel (LFE). They're 5.0. This is intended as there's no so deep sound to justify an LFE channel. For a full range speakers this is not a problem, they can play it all. For limited range speakers (like this) the crossover should handle the < 120 Hz frequencies (not covered by the satellites) and redirect it to the subwoofer. This is automatic. Now, on this specific system... the sound you'll get is *flat* especially the bass (the instrument). You're hearing something totally different from what was recorded. You can't also use digital because the audio is 5.0 PCM (and toslink/coax carries only 2.0 pcm).

All these problems go away if the crossover works equally for both analog and digital, like 100% of the systems out there (excluding Edifier).

Your suggestion also doesn't explain why Edifier S550 (the model I had in the past) had the right crossover for L/R but wrong for C/Ls/Rs. And that system was an analog system only.

I really hope someone from Edifier can clear this. I'm so close to picking one up from IPmart. There's no way on can perform the 5.1 test on site.

Ok, so i re-read all of your posts and i feel you drag it so long until ppl confuse on that already. So i came out with this simple conclusion:

1. For multi-channel (>2.1) analogue input with separate .1 LFE channel, you will still get bass from sub through separate .1 LFE channel from your source. But you want stronger bass due to the fact that LFE may only cover very low note (let say <50Hz, it depends on the producer how to encode the LFE channel), but your satellites can't go <150hz on paper, so you basically loss 50hz-150hz bass range.

2. You will only get into real trouble when you playback more than 2.0 analogue input (3.0,4.0,5.0) without separate .1 LFE, so you basically loss all the frequency note <150Hz due to your sub is not working now.

Are these points clear for you?

If yes, i think u need feedback to manufacturer/dealer. If they really don't have those setting that can re-direct bass and you feel unacceptable (yes, i do feel unacceptable), i think you should ask for refund the unit, i don't see any reason they can 'repair' ur speaker that design intended.

This is the first time we received complain that S760D having flaw.
Anyway, i already emailed Edifier International to contact bro mp3dom to check out what cause the problem.

Review of S760D - Review of S760D

Exactly

Yes, but it's the 5.1IN diperse that have the flaw, so whatever you send using that input, lacks bass management. You can send even 2.0 to the 5.1IN if you want (only L/R) and the sound will be flat. 5.1 will be flat too, it will sound the .1 encoded in the stream but will not redirect the bass frequencies coming from all the other satellites to the subwoofer.


It's not only that "i feel it unacceptable"... it's the fact that this is a wrong design (I don't want "more bass", but the "original amount of bass"). Clearly, changing the unit with another will not fix the problem as, I think, all the units produced suffer from this. The only wish is that a "revision2" will be produced with all the fixes (we're speaking here of the crossover problem, but there are also other two problems... the pops/crackles and the setting "Light = 0" on the controller which is not saved after poweroff (while light = 1/2/3 are correctly saved).


From the review posted by Edifier I can't find if all the tests were made via analog or digital (or both). It is possible that the website review the unit using digital connection and so this explain the positive results (as I said previously, via digital connection there are no problems for the crossover).

Another week... another no-response.
The only PM I've received here is from another user who is suffering the same problems... I'm just starting to think that it is Edifier (the company) itself who don't want to have a debate at all.

Wow, this is still ongoing even with bro Edifier on the case?

From the looks of it, you will definitely need to approach the sound engineers at Edifier itself for the level of question you're asking.. I dunno about the rest of you but it's just a little overwhelming for me and probably no one in this forum (which is based in Malaysia BTW) could solve. I don't think that the Sound engineers from Edifier will post here as well as they are most likely based in China so probably they did not view your posts here.

Not sure if you have but there is another email you could try, enquiry@edifier.com, I sure do hope that you can get a sound reply.

I sent emails to almost all the possible contact account (including enquiry) without success. I am deeply sorry to post here since I'm not coming from Malaysia but it's the only way I have to just try to get some support from someone from Edifier (as far as I know, there are no international forums about Edifier, nor Edifier seller that read posts like on this forum). Maybe my misfortune can be helpful for some other possible buyers.

I would also like to say that today, finally and happily, someone from Edifier contacted me. I wrote the problems already mentioned here and I'll wait for a response. I'll let you know if something happens. I would like to thank Edifier (the user here) to help me to get in touch with the support.

those random static pop really very annoying!!!

Are you using analog or digital connection? Onboard or dedicated soundcard?

If it's the same problem I get, it's from analog only and doesn't matter your soundcard. Infact it happens even if there is no connection at all (no input cable from pc to Edifier). Just power on the system, set to analog input and wait.
On digital it doesn't happen.

So the analog cables seem to be picking electrical noise..? Weird.
This also happens if you choose from other analog source like Aux or CD?

Uhmm not so sure they're the speakers cable because in that case it would be present even for digital connection (I also tried to change the cable but the pops still remains). More probably it's the amplifier that have something that generate that static noise when using analog input.
It happens for all the analogs, so 5.1IN but Aux-In and CD-In too.
Toslink and coaxial, being digital, are not affected.

Currently, if you own S760D, the only way to hear the sound as intended (right bass), without problems (no static pops/crackles), is to use digital connections only.

not too sure why did you guys get random popping noises because my testing period didn't do so. (and my house area has the dirtiest electric one can imagine) (been changing fuses non stop every time)

maybe I didn't get to test long enough

When you're listening something (unless it's... maybe... classical music) it is hard to hear it, because it get probably "masked" by the sound. It also depends by the volume on the controller. If you set low volume to (example) 10 and then the soundcard to 100% you probably can't hear the pops. In a quiet environment and controller set to 30 you can easily hear the pops.

FYI, we tested the S760D in our office and Edifier engineer also tested it in their lab and we can't find the problem you encounter. so, we suspect your unit might be faulty, please send to the dealers you bought from for warranty claim.

We already sold the S760D in Malaysia more than half year and haven't received any complaint and RMA yet.

Please don't set the sound card volume to 100%, sometime it will generate unwanted noise too.

The soundcard here is not the problem. As I said, the pops appears even when there's no connection at all to the pc/soundcard. Power on the S760D, with only all the speakers connected, is just enough to hear the pops. It is also better to no listen any music at all. Just keeps the system power on and wait in a quiet environment. The problem is that there seems to be no logic way to "trigger" the pops so it can appear after 40min, after 20min etc.

As for the faulty unit... please consider that I get that problem, infernore here seems to have the same problem and here:

https://translate.google.it/translate?sl=pl...m%2F&edit-text=

other users ("DrWiktor" and "ma4eusz" from March, 2014) are complaining the same problem. The "pops" are similar to when you switch sources (which in that particular case is normal) but appears on analog input even when no audio cables are connected.
Maybe the different electricity supply voltage can be partially the cause? Surely it's not a "disturb" on the electricity power supply, because I've the S760D connected to an UPS (APC Smart-Ups for precision) so the system is getting a pure sinewave power.
If it's a faulty unit... then the faulty rate seems to be quite high! More probably, seems there's something wrong somewhere.

Since you tested it, do you also tested about the crossover problem? Are you exactly getting the same sound from both analog 5.1IN and digital with right bass management?

Thanks for the info, will inform the Edifier engineer to test it out
