Hi.

I need to get analogue output from a synthesiser into a digital co-ax input port on a mixer, and I need the signal to be at a sampling rate of 44.1Khz.
It absolutely has to be 44.1 - other rates won't do here because I have a second device that's fixed at 44.1 already going into the mixer, the mixer
can only have one sample rate and so I need things to match.

I can find loads online that do 48Khz but have not found one that can output at 44.1kHz. Can anyone point me in the right direction?

Something like this?

Was unexpectedly busy last few days - damn, wish IrCOd have seen this first. Yes, something exactly like that in fact. I was recommended and ordered this: <https://www.amazon.com/dp/B0F59CCXZP>

Taken a week to get here, and says it auto-handles sample rates:
"The analogue to digital converter supports sampling rates of up to 48KHz for excellent audio performance. It is downwards compatible with 32K, 44.1K and 48K audio sampling rates.Note: The product supports audio in CM / LPCM format.rCY

Hmm. Would you like to guess what has happened? And thererCOs no dipswitch anywhere to control the output rate. Works perfectly at 48kHz, doesnrCOt seem to output at anything else. With no switches to regulate output...yep, this onerCOs heading back.

Cheers,
Ian

Hmm. So once again, the website clearly says:
"SPDIF/TOSLINK digital output, 44.1~192kHz sample rate control via dip switchrCY.

Sounds good. But click on the data sheet PDF at: <https://www.minidsp.com/images/documents/Product%20Brief%20- %20miniDSP%20Pocket%20ADC.pdf>

...and you get:

Hardware
rCo ESS ES9821Q chipset
rCo SPDIF & TOSLINK outputs for
computerless digitization
rCo 118dB SNR / -114dB THD+N
rCo Sample rates 48/96/192kHz

Notice no 44.1lkHz. And the manual goes on to show dip switch positions that donrCOt mention 44.1kHz either, but -do- have a mysterious rCyoffrCO setting that might be the missing 44.1kHz. Time for a mail to their product support I think.

All this, hilariously enough, is to get a Commodore 64-based synth working. One of these in fact:<https://www.twistedelectrons.com/therapsid>. It has analogue outputs, but the only port left free on my mixer is the
rCydigitalrCO (S/PDIF I think) input. Since I have another audio product thatrCOs locked to 44.1kHz only, an Akai MPC, that means I have to set the whole mixer to 44.1kHz. Drat. And double drat.

Cheers,
Ian

Would one of these work?

Marantz Professional PMD570. I'd assume (so high risk) that it outputs at the recording rate.

Overkill probably, but if it has other uses might fit the bill.
