The Grace Design m101 microphone preamp employs balanced, transformerless, transimpedance circuit topology to deliver huge bandwidth and headroom, as well as natural, musical and detailed sound.

The m101 is equipped with a new universal switching power supply that accepts input voltages from 100 to 240VAC. The front panel is a tough black anodized / laser etched black, which ensures legibility and usability in varying light conditions. And all preamp functions have a dedicated indicator LED, including the 48V phantom power and HPF switch.

Built in as standard is Grace Design's unique Ribbon Mic Mode, which bypasses the input decoupling capacitors, raises the input impedance from 8.1kohms to 20kohms, and defeats the 48V phantom power, preventing damage to delicate ribbon mic elements.

The gain range is 10-75dB, including the additional +10dB of gain available with the output trim control. This provides ample gain for use of any type of microphone in any recording situation. The gain control is a precision gold plated 12-position switch and the circuit path is built with 0.5% metal film resistors.

Included is a HI-Z input on the front panel. Rear panel I/O options include both balanced TRS and unbalanced TS 1/4" outputs, along with standard XLR balanced out and XLR microphone in.
