TUBE MP/C
Tube Preamp with Compressor
Loaded with options, the Tube MP/C is the most advanced member of the Tube MP family.
Like every Tube MP, its a mic preamp and instrument DI with real tube warmth. It features XLR and 1/4 connections, phantom power, boost, and phase reversal.
It also has a robust compressor. When engaged, the circuit offers variable threshold, switchable fast or auto release times, a switchable slope for compression or limiting ratios, and gain reduction metering.
Unique among the Tube MP family, the MP/C can switch the outputs between line level and instrument level. Line level is typically used when connecting to other recording gear like audio interfaces or signal processors. Instrument level can be used in applications such as sending a recorded DI track back to a guitar amplifier for reamping, or for connecting the XLR output to a mic preamp on a console.
A front-panel instrument input, tube drive and output level meters, and a switchable 70 Hz high-pass filter complete the feature set. Compact and powerful, the Tube MP/C brings the versatility of a channel strip to a convenient desktop format.

- XLR balanced inputs and outputs
- Transformer isolated XLR output
- Selectable output range for Line/Instrument interface levels
- LED meters for Tube Warmth, Gain Reduction and Output level
- +48V phantom power
- Phase reversal switch
- Selectable release time settings
- > 90dB dynamic range
- Custom extruded aluminum chassis
