The USB Dual Pre is really three products in one, packed into a compact, rugged case:
- A fantastic stereo mic preamp
- A dual-channel USB audio interface
- A battery-powered portable preamp to link up any pro mic to any digital camera
Each of the two low-noise input channels has up to 48 dB of clean gain with signal present and clip LED indicators. Inputs can be either XLR or 1/4" Jack.
Each of the 1/4" balanced Jack outputs is buffered and low impedance.
The USB Dual Pre can be externally powered from the mains via a supplied 12 V adapter, or from an internal 9V battery, from the USB bus itself, or any combination of these power sources.
When running off of the battery alone, you should get in excess of 50 hours of operation when phantom power is off, or up to 20 hours (depending on microphone) when phantom powering from the battery alone. The built-in low-noise +48 Volt phantom power supply allows you to power up to 2 microphones from any of these power sources
