Hello,

can I use dual-channel measurements with Arta using umik?

We've never use Arta in that manner but I'm guessing that it's for some sort of feedback that you'd be doing this?
The UMIK-1 is not in that picture important I'd guess.

Normally acoustic measurements are done in dual-channel setup, check out Arta manual:

3.1 3.2 etc

For dual-channel measurements, such as in #12002 the analog signal is necessary. It is possible - whether to take it after the preliminary amplifier, before processing of a signal in ATsP? If yes, specify this point on the printed circuit board, please. I think, existence of such opportunity considerably will expand possibilities of UMIK 1, as tool for creation of loudspeaker systems. My microphone of serno: 700-3957.

Hello Ssergo,

Sorry but it's not possible I'm afraid. No analog input path on the UMIK-1

Wouldn't need to be analog. Just a return path, i.e. UMIK-2 presents itself as a USB two channel input and 2 channel output device:

Output
- Channel 1 > Digital (or analog) out
- Channel 2 > internal loopback to channel 2 input

Input
- Channel 1 > mic
- Channel 2 > loopback from channel 2

Markus,

We were just answering the question from "ssergo" asking if you can DIY something on the UMIK-1. That chipset is a ADC only, it has no output/input I'm afraid.. So unfortunately not possible on the current UMIK-1

Or think of a new UMIK-2 doing as you suggested. :-)
