New Sound Devices USBPre 2 about to be released


Recommended Posts

Also the XLR outputs on the bottom makes it harder for bag use.

No power input.

S/PDIF In/Out & Aux In/Out on the end

Has USB powering option, so it just needs a power cable with a USB plug. It can work in stand alone mode as long as it has power going into the USB socket

You best bet is to use a DC to DC regulator that will isolate your 12VDC (presumably high current) source with your 5VDC output, likely rated for 500mA max, maybe 1A if you want to chain a few devices or support future USB3 power requirements.  The USB Pre 2 claims a max current draw of 100mA.  If there is enough interest, I could even build a few 10x AA battery packs (15VDC alkaline or 12VDC NiMH/NiCd) with a regulated 5V USB port.  (Digikey wants me to purchase the battery holders in quantities of 100)

I stand corrected, 500mA during operation.

500mA max draw during normal operation. 100mA max draw on enumeration (Boot up) to comply with USB hot-plugging specifications.

Anecdotally: A few days ago I had a 788T powered with a bench supply to test the operation of the USBPre 2 in stand-alone mode while attached to the 788T's keyboard USB jack. With 2 phantom powered mics attached (One a current-hungry Earthworks M30), inputs gains cranked, headphone gain cranked (With headphones attached), the 788T was showing about 200mA~300mA increase in current draw (With 12V from the bench supply).

The price difference would be a few $

I do not want to use the 522 for recording because the converters are poor compered to almost every Audio Equipment out there.

$2900 for a mixer and they could not fit physically or within there budget the converters from USBpre2?

Major downside. And like John says : there are other devices that have the functions needed.

I just think it sucks.

Also people have to buy ZAXCOM or SONOSAX if they want more then 0db maximum before clipping.

Never understood this low spec.

" Why does the usbpre2 has better converters then 552 "

maybe because it is primarily a converter, and the other unit is primarily a mixer...???

" I do not want to use the 522 for recording because... "

then don't.

The recording features (including converting A to D) are a terrific bonus, and make an excellent backup to a 2 channel hop, or a transcription copy.  The 552, without the digital recording capability would still be a terrific value ...
