Would you try testing the ADC performance with lower input level? -6db -9db something like that?
That is in the IMD versus level graph.Would you try testing the ADC performance with lower input level? -6db -9db something like that?
Well, my personal interest in measuring gear is about that kind of device.No to all. I have the thing packed to send back. Speak if you must have those measurements and if so, please be specific.
I have a few moto boxes, along with the newer pcie card, and have been pondering hooking up the 896mk3 (hybrid USB 2.0 and firewire) and see how it works as a standalone interface either as a DAC, or for usb->aes digital multichannel distribution.

Any thoughts would be welcome...trying to work out a multichannel home theater solution with these until a decent AVR comes along.
I guess any trim output is purely digital, and it probably makes no difference where you set it.Hi,
Di you set -8dB with TRIM (ESS DIGITAL VOLUME) ? IN DEVICE MENU ? ( -24 dBu variable from +20dBu)
20 dBU - 6 db = 14 dBu to have 4Vrms with TRIM menu, not in MIXER

or the DSP MAIN OUT MIXER volume ?

I think result could be different at 4Vrms depend on -8dBd the DSP volume (MIXER) or the TRIM that use DIGITAL VOLUME of THE DAC.
Same for ADC :
Trim at 0 ?

I can't say how it will work universally. With USB over ASIO when the playback software can use ASIO it should switch sample rate to match the playback software. Obviously this is with Windows. With Mac I think it will also switch over USB with most playback software.Hi
My first interface like this was a Motu 828mkIII (first, firewire only, edition)
The problem to use the 828mkIII as a DAC is lack of automatic frequency switching.
If, say, you want to feed it with a streamer from Tidal or Qobuz, you'd end up changing the frequency manually on the interface between each track/ album.
I don't know if that's the case with this USB one, but that was a show stopper for that kind of use for me.
By the way, I also have a pair of 2408mkIII.
That was kind of SOTA back in time... in 2002/2003
If you puzzle through the big users guide I linked up thread it has most of the info to figure out the answer to this question.I guess any trim output is purely digital, and it probably makes no difference where you set it.
Mic input front-panel Gain setting is most likely different thoug.
Did you try it with one of those interfaces?I can't say how it will work universally.

+1 for the Mic measurement.Well, my personal interest in measuring gear is about that kind of device.
Mic preamps, for sure, are of interest.
At least as much as line in.
Ideally, you want to simulate a 1mV 50 ohm microphone, with enough gain to reach near 0dBFS, and see what happens, in terms of noise, distortion, bandwidth, frequency response, linearity, max level, max and min gain.
Not with a Motu no. With other brands with ASIO yes. It does with some playback software, and not with others.Did you try it with one if those interfaces?
Strange, but there is no block diagram in the manual.If you puzzle through the big users guide I linked up thread it has most of the info to figure out the answer to this question.

Interesting. What HT setup do you have in mind? I was thinking about the same, but couln't find a processor with at least 20 digital outs that does Auro 3D, DTS and Atmos.
That's a fair point...While testing mic preamps would be nice for those that use them, this is primarily a consumer site AFAIK so adding that may be a stretch.
