While I haven’t measured the idle current draw these are big amps so they likely use some decent amount. For that reason alone Inwant them off when not in use. I use an IoT Relay power strip with the 12 volt trigger on the WiiM. Works like a champ. The amps have a very nice soft power up with no pop. You could use a line voltage strip probably also.
 
What is the recommendation for how often to turn off the power to active speakers in general and the C8Cs in specific? Nightly? When going away for a few days? Never?

I don't care what anyone says, I turn my off. I use a smart power-board and a google thingy and say "Hey Google, speakers off" and they are off.
And of course the opposite to turn them on.

can you describe in more details how you set that up? I'd like to do the same. Thank you

You need a smart power-board that uses WiFi and advertises the third party service you want (Google, Amazon Alexis, etc.). But don't skimp on a small and low quality smart power-board, I did that before and it couldn't handle the power draw from my active speakers (D&D 8C) and they would switch off during loud moments in movies. Connect the smart power-board to your WiFi and mobile device using the app that's made for the smart power-board. It will surely comes with instructions. Then it should have an option within the app to link it to third party services and/or you may need to link it with the third party service app e.g. Google Home.

I would turn them off when you are not listening to them. This is my generic advice for all audio electronics.
Same here. I generally try to avoid standby operation with sensitive electronics and turn them off using the mains switch on the device (if there is one) or by using a switchable power strip.
 
Hello together, why can I not select the soft clip on the right speaker? On the left speaker I can modify the soft clip limiter and can select it. Thanks in advance :)

Hello. It looks the setting is wrong.
Can you DM me? I’ll fix it by remote connection. Sorry for the inconvenient experience.
Hello @AsciLab! I encounter the same: on one speaker Soft-clip is not enabled and I sent you three emails in the weeks after delivery already without receiving any reply on how to fix it.

While I appreciate your support through remote connection for serious issues, wouldn't it be more feasible to overwrite all settings / restore to the intended factory defaults with the new firmware update? I guess @danielst2711 and I, we are not the only customers affected by the different settings.

Also it would require me to have a friend's Windows laptop available at the established time, which will be challenging - also because of time zone differences with Korea (wouldn't want to make you work at night^^) - or to set up a VM for Windows, if Hypex driver pass through works well towards the Debian Linux host.(?)


By the way, I bought the C8C because I found the excellent manufacturer measurements and then review - on ASR! Yes they really sound as great as I expected. :)

Did you send email to [email protected] ?
We didn’t get any email about that. Would you please send the email again?
 
"When in 'Sleep' mode (waiting for wake-on-LAN), they consume roughly 7 watts."
That would be the best solution certainly. But they do not enter sleep mode properly with the WiiM, thought by AsciLab to be due to low/inaudible levels of noise. I struggled with this for a long time then decided to just use the power strip. Way easier. Everything is happy now and the speakers turn off immediately when the WiiM does instead of unpredictably after the sleep timeout.

This may be a problem just with analog or even just with RCA cables. YMMV

How would the problem manifest? The front LEDs would turn green all of a sudden?

I’m using a Wiim out Coax (not analog) to the C8C and it never happened

Yes, first email describing this with screenshots went to Mr. Changyeul (since I repeatedly had not received any reply from [email protected] on my previous pre-delivery enquiries but your CEO responded promptly instead), second to Mr. Jinsung and third then to [email protected] :D

I believe somebody should have received the emails (no delivery error occurred). I would have waited for the V1.1 update to see if it fixed the settings, if it hadn't been mentioned by @danielst2711 just now.

Will send the email again to admin from my mailbox.org account. Just in case you have to filter for it: I believe not many of your customers use this provider. Thank you.


Additionally:
Also, a friend of mine and C8C customer will send you an email to [email protected] within the next 2-3 days. So please look out for his message as well @AsciLab.

We found that one of his units does not output sound after power up unless the preset is being changed: like from P2 -> P1 [-> P2] or the other way around. He'll attach a short video clip from the HFD interface with the VU enabled.

@pat355 Symptoms are: They will turn off after a few minutes (timeout value?) and then back on again after 10 seconds or so. You can change the sensitivity thresholds but too low never sleeps and too high never comes on. Too tricky and fiddly IMO and for $35 I got a permanent and actually superior fix.

BTW: Lest anyone is reconsidering buying C8Cs due to this and other software quirks, do not reconsider. I am in continued awe of their performance and any headaches are well in the rearview.

Are you using digital input?
Need to set both as master and low power mode to wake up with digital signal. You are doing this manually by changing presets. Ascilabs detail this in the quick start guide

It could be.

My slave unit didn't wake up (SPDIF through coax) when I powered off both speakers for a few days. I ended up needing to plug the slave unit into my computer, set it to master with HFD and re-do the master-slave configuration from the start.

Nothing to mention since then, but I never power off the monitors, I just let them go to standby after a period of no activity.
 
thank you! :)
No worries, one thing I forgot to add was in the smart power-board app, there should be an option to rename it. It will probably have the Model Number as the default name and you will probably want to rename it to "Speakers" so that when you ask Google/Alexi etc, it will no what you're referring to turn on.

Also, so smart power-boards (such as the one I have) allow you to switch each outlet on/off individually and to name/rename each power outlet individually. So you can have multiple devices each with their own name. Because I have two active speakers, both are renamed to "Speakers" so that both go on/off with the one voice command.

No, we tested both analog RCA and XLR inputs and to be sure, even forced these inputs on the HFD app. This has the advantage that the amplifier won't fall back to search for inputs, when volume is being low: below internal -72 dB threshold. But will have a closer look on the device settings page, maybe there's a mismatch.

This behaviour could not be reproduced on the other three C8C we have at hand. And there's also sometimes a popping sound on that speaker during playback, if this happens to be related.

My instinct woud be to factory reset -> possibly update firmware -> reset again the speaker and see what happens. # I attached my friend's short recording @AsciLab.

I have 100% the same symptom: If I power them off, the slave unit doesn't wake up (also SPDIF through coax).
To resolve this,I didn't do a reconfiguration. I had to let both the source (Wiim Ultra) and the master go to standby. Then play some music again and at that time both speakers came on, but not initially as is supposed to.
