mono all tube mixer pre-amplifier with XLR input & output

This is our 2nd model of tube mixer pre-amplifier that's built for those who require a warm and natural tonal quality during recording including live performances. One XLR mic input with 48V phantom power, one XLR+1/4" line level input with mixing functions. After the mixer stage is a non-negative feedback line pre-amp stage that has both 1/4" and XLR outputs to drive another recording device or power amplifier down to 600ohm input impedance.

This unit can also be used for Karaoke, or to amplify your acoustic guitar output when mixing in a CD signal for monitoring purposes.

This pre-amplifier is a no-negative-feedback design that achieves a very open sound stage.

This unit is all hand wired with no transistors, regulators or printed circuit boards in the signal path or tube section, so this ensures a high quality open and natural sound. Satisfaction guaranteed as always.
