Tube Channel Strip

The 376 puts the best of both worlds into one affordable package by combining the warmth of the vacuum tube, with the proprietary dbx Type IV conversion system. The 376 boasts a +48V phantom power, a phase invert switch, and low cut filtering, in addition to digital output capabilities in both AES/EBU, and S/PDIF formats. A high impedance, 1/4" instrument input located on the front panel, as well as the mic/line switch, and 20 dB pad. The LED meters provide a clear and concise visual of the signal processing at a glance.
