Grace Design M101

Maintaining Grace Design pedigree throughout, the m101 employs our balanced, transformerless, transimpedance circuit topology. With incredible bandwidth and headroom, the m101 is natural, musical and detailed, allowing engineers and musicians to consistently record vibrant, amazing tracks.

The m101 is equipped with our new universal switching power supply, which is dead quiet and 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 our unique Ribbon Mic Mode, which bypasses the input decoupling capacitorss, raises the input impedance from 8.1kΩ to 20kΩ, and defeats the 48V phantom power, preventing damage to delicate ribbon mic elements. Ribbon mics, you’re welcome.
