USB DUAL PRE PS
USB Dual Preamp & Computer Interface
The USB Dual Pre is a two-channel preamp and audio interface thats ready to record anywhere you find inspiration.
Each channel has a combo jack for XLR and 1/4 connections, and up to 48 dB of input gain to boost mic, line, and instrument-level signals. The rear panel has a phantom power switch, a level control for the 1/4 outputs and headphones, and a blend control to mix the input signals and USB playback for true zero-latency monitoring.
It can be powered by USB, a 9-volt battery, or an optional external adapter. The expected battery life is approximately 20 hours with phantom power, and over 50 hours without. Using a battery or adapter will reduce the power draw on the host device for extended recording time when tracking remotely.
Its class compliant, so no driver software is required, and the metal enclosure is compact and rugged, so the interface is portable and protected. Whether in your home studio or a mobile setup, the USB Dual Pre will capture great sound wherever you record.
