GRACE DESIGN / m103

GRACE design has finally released the ""m103,"" their first channel strip equipped with a microphone preamp, compressor, and equalizer!

~From the manufacturer's website~

The m103 is a powerful channel strip featuring a high-quality GRACE design microphone preamp, a 3-band EQ, and a fully-controlled compressor.

The transformerless microphone preamp circuit, which perfectly captures the raw sound, faithfully reproduces the functionality and sound quality of the classic m101. The 3-band EQ section has a single-stage parallel tuning structure. This efficient circuit design achieves natural tone shaping across all frequency bands, respecting the artistry of the music. Full parametric Mid, Hi, and Low controls feature shelving/peaking modes.

The compressor circuit employs an optical attenuator for the purest possible design. GRACE design's unique gain control mechanism allows for a wide range of compression, from gentle limiting to heavy compression, while always maintaining a neutral and transparent sound. Its greatest appeal is its clean and vibrant sound.


Furthermore, the m103 allows you to change the connection order (microphone preamp → EQ → compressor, or microphone preamp → compressor → EQ), enabling you to fine-tune the settings to suit your application. It's arguably the highest-quality sound tool currently on the market, a perfect all-in-one unit.
