Since it is also able to operate as a interface on the computer, the powering requirements are going to be identical. Specifically: 5V +/- 10%, 500mA max draw. So it will need a regulated 5 Volts on standard USB wiring from a power supply that can give it 500 mA at any given time. I've actually gleaned a lot of information about powering solutions from this thread. A lot of our customers are in the film and television field and they are used to powering solutions like 14V NP-1 batteries, 7V L-Series batteries, etc. and they are inquiring a lot about how to power the USBPre 2 in the field for stand-alone use.
I wonder how the D/A (and headphone out) is on the unit.
There is a lot of headroom on the headphone output and it is very clean. It is fully capable of driving even some of the really high-impedance headphones to very high levels. It will feel familiar to anyone who has experience with the headphone amps in our other products.
Is there any more word about when the big dealers will start selling this and the actual release date?
Mid to late October is when retail stock should begin arriving to our resellers.
is there any word if you can use the RCA outputs and the Coax out at the same time??
The stereo signal from the internal bus is sent to all outputs simultaneously. You can send 2 channels out S/PDIF optical, 2 channels out S/PDIF coax, 2 channels out balanced XLR, 2 channels out unbalanced RCA, and 2 channels out both headphone outputs all at the same time.
Great to see SD post here! Now how about an upgraded 744 with four pre's instead of two...
That's a request I hear more than occasionally. I'll certainly pass it along.
