Get to know them!

With the m103, Grace Designs has combined some of their finest transformerless circuitry to release a channel strip that meets their extreme criteria of high headroom, intricate detail, and immaculate clarity. The m103 comes complete with a 3-band equalizer, optical compressor, and comprehensive I/O options that let you access the preamplifier and equalizer/compression sections independently, so your options are far from limited. The compressor controls of two m103s can even be linked to allow for stereo applications. And since it's from Grace Designs, you can expect their signature neutral transparency out of the m103 channel strip.

The lucid transparency of transformerless design keeps the mix clea

Grace Designs approached the m103 by using their legendary m101 transformerless microphone preamplifier circuity. The m103 includes a 75Hz highpass filter and 48-volt phantom power, as well as Grace's exclusive ribbon mic mode to better accommodate the relatively low impedance and resulting low output of most ribbon microphones. Ultimately, the signal path remains untainted from most noise and yields a truly musical character.

A complete equalizer and compressor section lets you tune your sound

The m103 features both a 3-band equalizer and an optical compressor for maximum control over your sound. The equalizer is based around single-stage parallel tuning for a natural and musical tone at all frequencies. It features a fully parametric midrange control, as well as shelving and peak modes for the high and low bands. The optical compressor circuit provides gentle limiting to fairly heavy compression without adding excessive coloration, so you can use it with a heavy hand and not worry about distortion. With the push of a button, you can switch the order of the equalizer and compressor, and you can also link the compressors of two units for stereo applications.

Comprehensive I/O options allow for creative applications

The microphone and equalizer/compressor sections of the m103 are independently accessible. This allows you to gain access to capitalize on the transparent preamplifier and take full advantage of a heavily colored external dynamics unit. Conversely, you can also run a heavily colored preamplifier into the neutral dynamics section of the m103 and compress the signal without adding additional color.

Grace Designs m103 Features:

  • Transformerless microphone preamplifier based on the m101 circuitry
  • 3-band EQ with parametric midrange and peak/shelf options
  • Optical attenuator-based compressor with linking option
  • Comprehensive I/O for added compatibility with other units
