No DSP?

Hello.

I don't know because I'm not part of the SMSL company or any other company for that matter.

I wrote in my post: "That's all I could find on this DAC so far..."

In addition, it seems to me that SMSL would have indicated in the characteristics if a DSP was present.

Moreover, when you look at the size of this DAC you wonder how they fit everything into it

Sorry.

NB: find on the net

I've recently set up a desktop listening station in my home office, and I was looking for either separate DAC and Headphone amp, or ideally a combined product, so I've just ordered one of these, in addition to a DL200 to see if they truly are the same. I wasn't able to find any specs beyond the OP online, and I'm hoping a little more might be in the manual.

Previous to this I was using a Scarlett 2i2 Audio Interface, which looks nice, if you like the red anodised enclosure, but may not be the best DAC and certainly isn't the best headphone amplifier, so I'm hoping for some improvement overall.

One question I do have, is if the volume control on these products applies to both the headphone output and the line level outputs that I'll be passing to a small amplifier? If so, what is considered best practice here?

• Control volume with the downstream integrated amplifier and fix the DAC output to max
• Control volume with the DAC output and set the downstream amplifier to max
• Some combination of the above

I'm sure I'll have some other questions, but that will do for now.

I recently received the SMSL C200 PRO, and I’m experiencing a problem that keeps happening.

This tends to happen when audio is currently playing or temporarily paused in a browser (like Chrome) or any audio app, and I do one of the following:

- Turn off the DAC using the remote and power it back on almost immediately
- Switch through the input modes using the remote (USB → OPT → BT → COX → USB)

About half the time, the audio comes back with a noticeably lower pitch — voices sound unnaturally deep, like the playback speed has changed.

This issue only occurs when the DAC is in USB mode.
I’ve noticed this happens most frequently when testing with YouTube in a browser.

There are two temporary ways to fix it:

- Change the sample rate manually in Windows, which makes the DAC reinitialize the sample rate
- Close all audio-related apps and browsers, then turn off the DAC, wait about 10 seconds, and turn it back on

However, even restarting the entire PC doesn’t solve the issue, so I don’t think it’s a Windows or PC problem — it seems to be something inside the DAC itself.

I often switch between OPT and USB, so this problem is quite frustrating for my usage.

Has anyone else who received the C200 PRO experienced this?

Hi @doodoodude, yes, I've experienced this behaviour as well; see my post here: https://audiosciencereview.com/forum/index.php?threads/smsl-c200-pro-observations.62367/post-2287690

Hi
Are you experiencing exactly the same issue?
If it’s not too much trouble, would you be able to test it using the method I described when you have some time?

All you need to do is play a YouTube video in Chrome (preferably with someone speaking), and while it’s playing, use the remote to cycle the input mode and return to USB. (USB → OPT → BT → COX → USB) Then see if the pitch issue occurs.


I’ve already contacted both Aoshida and SMSL about this, but they told me they couldn’t reproduce the issue on their end.
However, If you're experiencing exactly the same issue as I am, then including myself, one person from another forum, and now you here on this forum, that makes three people experiencing the same problem — so I don’t think it’s due to a defective unit.


My guess is that this could be fixed with a firmware update — maybe by adjusting how the DAC handles sample rate initialization when changing input modes or powering on. But I’m not sure if SMSL will actually address it.

No, not exactly the same. I only have access to Mac, not Windows, so I can't comment on using Chrome.

The approach that I took was to play some music in the Apple Music app, then either hot-plug the USB, or toggle the input mode and return to USB. In both of those cases I frequently had issues.

I agree, especially as the DL200 does not have this issue. My guess is that something from DL200 needs to be ported to C200 Pro. Firmware updates have been made in the past, but I don't see one for the C200 Pro yet.

Thanks.

I just tried playing music from Apple Music on my phone, and when I hot-plug the USB-C during playback, or start playback on another input and then switch to USB, the same issue happens.
Seems like exactly the same problem.

SMSL doesn’t even have an official product page for this device yet.
At first, I contacted SMSL directly, but they didn’t give me any reply and just forwarded the issue to Aoshida Audio by email.
So right now, I’m communicating with Aoshida Audio about this.

I'm planning to talk with the aoshida audio a bit more before deciding whether to return the product, so it was important for me to understand this part clearly.

 

[Nezil]

I’ll be returning mine for this, and another reason - terrible Bluetooth range; I suspect there is an issue with the antenna wire.

I wanted to like the C200 Pro, but the DL200 seems to have slightly better features, and it’s cheaper, and the RAW MDA 1 better still, though much more expensive. It’s between those two for me now.

I just received an updated firmware that fixes the issue, and everything now works as expected.

What changed: with the old firmware, if the input mode changed or the DAC was powered off so the USB device disappeared, any video or music that was playing would automatically pause. With the new firmware, playback no longer stops (even if the USB device disconnects), just like it already behaved on the OPT input. It looks like SMSL simply worked around the problem, but I’m fine with that.

I’ve attached the firmware link here for reference, in case it helps anyone facing the same problem.
