The ART USBDualTubePre is a compact, dual-channel tube preamp designed 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 optocompressor circuitcapable of ensuring superior dynamic control of any input source.For monitoring, an 1/8" mini headphone jack with level and monitor mix controls allow latency-free monitoring of the inputs while recording, as well as playback monitoring of audio mix via USB bus. The monitor mix is also routed to 1/4" TRS (balanced) outputs with separate level control for control room monitor source.The USB interface is fully USB compliant. No special drivers are needed.
