Hi, the DN9630 is an AES50 <-> USB interface and this is the closest forum I could find. Does this device really only support 48k and 96k? Doesn't support 44.1 nor 88.2?
Yes, only 96kHz / 48 kHz. The idea behind the DN9630 was to be a lower-cost recording/playback option mainly geared towards our Midas PRO Series users. Prior to the DN9630, users would need to incorportate a Klark Teknik DN9650 w/ Dante or KT-USB card options (or third-party RPM Dynamics interfaces), which are quite expensive if you're simply looking to track shows or use for virtual sound check.
The 48kHz option further add to the market for our M/X32 users -- as most people are using the 48kHz sample rate. Further, many of our 'Blue' DL15x, DL25x, DL231 Stageboxes only operate at 96/48 kHz so this is in line with those product ranges.
Apologies, it really wasn't meant to be implied that way. Nearly all AES50 peripherals relating to PRO Series only 96kHz and 48kHz, such as the DN9680, DN9650, DN9620, DN9610, All 'Blue' I/O boxes, and lastly the DN9630. For M/X32 users, I think the majority of applications where a DN9630 would be used would be in the DN32-USB card is replaced with somethng like the DN32-DANTE card -- and typically users set the sample rate to 48kHz.
Although it sounds like you were looking for a 44.1kHz solution and in that case, I understand your frustration.
