May I ask if 760d have the same problem as s550? The problem is regarding the crossover for Center and Surround channels. Basically, Front Left/Right sounds right but Center and Surround have bass frequencies not redirected to subwoofer so basically they sound "flat" if you output only to center/surround. This can be annoying on movies because voices coming from center have no "rich" sound. Seems like they're coming from a radio.

Well, thank you very much for the reply. No problem. I sold the s550 and I'm getting the s760d right now. I'll test and let you know, just in case. Thanks.

Ok, just coming back since I've received the s760d. While I'm generally happy with it (the crossover bug is finally fixed) now I'm having other problems (is it so difficult to sell products with no problems, eh Edifier?!). One is that Light 0 on the controller is not saved (light = 0 means that the display will turn similar to off after some seconds). If you set light=0 on the controller and then you power off the system, when you power on again the light defaults to 2. This doesn't happends with other values, which are correctly stored. This is a cosmetic bug which doesn't affect the usage.
What is affecting is that I'm getting some crackles/pops from the right speaker without any apparent reason. It is not a PC/soundcard problem because the crackles/pops appears even without any connection (!!). I mean... pc off, no cable connected... only the speaker on. Is not a power fault either because I've attached the system also to an UPS (APC, with pure sinewave, so the power is almost perfect).
I can't get an idea of why this is happening. It appears without any reason... there are cases when it appears after 20 minutes and other when you can hear 2-3 pops within 1 minute. It's so disturbing (!!).
What can it be? Other are getting the same problem?

Sorry to bump... but this system is completely faulty in its design... even worst than s550. I can't understand the OP review at all. Apart the pops/crackles (I've seen other post around the net where other people are getting the same problems, so it's not my unit which is faulty), the inputs that works as expected are the digitals (toslink 1-2-3, coaxial) and CD-IN/AUX-IN. The 5.1 IN is completely wrong in its design. In S550 the crossover was wrong for Center and Surrounds (bass not redirected to subwoofer) but L/R works as expected. In S760D even the front L/R are missing the bass redirection!. This is clearly audible if you listen a 5.1 file via analog in and the same file as Dolby Digital. They should play the same but it is not! The Dolby/dts version (digital) have correct bass-redirection, sounds perfect with strong bass. The analog version on the other hand sounds 'flat'. The subwoofer sounds only if there's sound coming from the LFE channel (of a 5.1 mix) but it should also play the bass frequencies coming from the other channels (due to bass redirection)! Why this doesn't happens? Oh my god! This is totally wrong!

The OP says "But even on a 5.1 analog input, the subwoofer bass is still present but low in volume. Common 5.1 would just have silent subwoofers when music is played.".
Absolutely not. Common 5.1 have bass redirection applied so even if the source doesn't have an LFE channel, the subwoofer still works *if needed* when there are lower frequencies not covered by main speaker. This is the bass management. The low frequencies doesn't just get "discarded". Common 2.0-only systems doesn't need subwoofer because they already have woofer for bass frequencies (other than mid and tweet).
If you use Dolby Digital Live (encode whatever is the source to Dolby Digital) you can hear the right bass redirection applied. The Dolby Digital Live version (5.1) plays *exactly* as if you use analog AUX-IN or CD-IN.

To summarize:
For stereo source: You can use analog AUX-IN or CD-IN or, alternatively, digital (optical/coaxial). This all plays fine (excluding the pops)
For 5.1: You are obliged to use optical... so Dolby Digital or dts is fine. If your source is 5.1 wave or other formats you need to enable Dolby Digital Live or dts Connect on your soundcard (if you have those feature). Absolutely avoid 5.1 analog IN. It is faulty and plays wrongly. The fact that 5.1IN is faulty is a BIG problem because:
- You can't use a better DAC (I have an Essence STX II which has far better DAC than the one you can find inside S760D but I just can't use it)
- You can't do your own 5.1 mix (the sound you hear is not the sound you're mixing)
- You can't watch your bluray in highest quality (dts-HD Master Audio and Dolby TrueHD should be decoded and sent via analog if you want to hear the full quality and not only the "core" which is the compressed part).

If your soundcard have the bass-redirection management via driver, you can try to use 5.1IN. You need to set the crossover frequency near 120 Hz (in that way, all frequencies below 120 Hz are sent to the LFE channel of the soundcard, so you overcome the faulty bass-redirection of the Edifier).

More than 700$ for a system that I can't use at its fullness, which sometimes pops, where I need to only use digital connections when I want to hear the sound as it should and I can't even use my DAC... I'm crying.
I'll never buy Edifier again! Guys, don't buy this system!

I really appreciate the answer. Can I get in touch with someone from Edifier that can answer me via email? In my country (Italy) there's no Edifier Multimedia dealer so I've bought it via Amazon Marketplace (external seller from Poland which uses Amazon as a store). For warranty claim I need to send the system through international shipment. Prior to spending a lot of money for shipment (due to high volume/weight) and have in return "the same system" (new but that works in the same way), I would like to know if the S760D, by design, have the bass-management as I explained above (reading the OP review, I would say that it is a design problem since he's confirming the same results with another unit). I can send a lot of "test files" which can clearly shows where's the problem. I really would like to fix this (for me but also for Edifier). The system, when working correctly, is really good but actually has so many flaws that it is almost not "usable" for some serious work/listening. All the similar systems from Logitech or other brands are almost "toys" (but have bass-management working as expected) so Edifier is the only choice available for a pc environment (excluding higher priced studio monitors).
Thanks.

Well, I can ask to those reseller but they sell Studio models or Image models (infact, Multimedia models are very hard to find here). Maybe they'll support me even if I haven't bought it from them.
I've already sent emails some days ago to the Edifier International Support and EMEA (Europe) support. Obviously, they haven't answered me. Without any support from Edifier, the only choice left to me is to write on forums. This is why I've wrote here.


Ok, true AV receiver are better, I think the same. But the crossover problem is only for Edifier. I had in the past a (very) old Creative DTT2500. It's a consumer 5.1 system (one of the first in the market in the old days) but has the crossover setup correctly. The same apply for Logitech 5.1 models. They doesn't output HiFi sound quality but the "design" itself is right. On the other hand, here we have S550 which has right crossover setting for L/R but wrong for C/Ls/Rs, and S760D which has all wrong crossover setting for analog on all channels (digital is working right).

Thanks for the support


I've send it via PM just now. Please let me know. Thanks.

Uhmm, I don't think it is the software player that should do an analog bass-management. All the speakers are different from the others and it is not expected that a general user knows how to setup a software for bass-management purpose. Also, if you use ASIO as an output path, you have direct access to the hardware so the software player settings (but also the soundcard drivers) are just ignored (totally bypassed) and so the problem it is still not fixed. If I use the soundcard driver to manage the bass (ASUS/C-Media cards have the so-called "Flexbass", Creative have something similar) you have a quite good bass management (better than with no bass-management at all) but it doesn't sound as good as the original bass management (that you have when using digital connections). I agree with you, this is a design flaws. I'm only waiting to ask for a refund because If Edifier contacts me (not happened yet) I can made tests directly to the unit. I think it is in the Edifier interest to (at least) try to fix/investigate the problem (if they want, obviously).

Just to let all you know, exactly after a week, nobody from Edifier contacted me via email or here or even answered to my emails sent to the international support.
Even more disappointed.

Unfortunately, nobody.
Thanks for taking this into account.

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, 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.

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.

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.

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.

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.

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.

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?

In those 1-2 months, did you test it extensively using also analog input? Static pops cames out only when using analog input, not digital.
Also, on your test unit, using 5.1 analog input, had you no problem with bass management? You already 'catch' the problem when feeding 2.0 sound using 5.1 analog input... but I mean 5.1 input using true 5.1 signal (compared to digital)
