USB Dual Tube Pre

Two Channel USB Tube Preamp
The USBDualTubePre is the ultimate compact dual channel
tube preamp for any basic recording system. Capable of
operating as a standalone unit with USB audio interface, or
as an expander for any digital system with s/pdif digital input,
each channel in the USBDualTubePre delivers superior tube
tone in a fully featured input strip.

Each input of the USBDualTubePre has independent input gain
control and output level, phase inversion, low frequency roll-off,
true 48v phantom power and a user defeatable opto-compressor
circuit capable ensuring superior dynamic control or any input source.

For monitoring, an 1/8-inch TRS mini headphone jack with level and
monitor mix controls allow latency free local monitoring of the inputs
while recording as well as playback monitoring of audio mix via the
USB bus. The monitor mix is also routed to the 1/4-inch TRS balanced
outputs with separate level control for control room monitor source.

The USB interface is fully USB compliant. No special drivers are needed.
