Grace Design m103: preamplified quality and versatility in one channel

The Grace Design m103 is a mono channel strip designed to deliver the highest level of performance in audio recording and production. Based on the m101 preamplifier, it integrates a musical and transparent audio path enhanced by a three-band equalizer and an optical compressor. The result is a complete solution for precise and natural signal processing.

3-band EQ for complete tonal control

The m103's equalizer employs a single-stage parallel tuning architecture, ensuring musical and natural intervention. The mid band is fully parametric, while the high and low bands can operate in shelf or peak mode, allowing surgical or wider interventions as needed.

Optical compressor: transparent dynamic control

The compressor is based on a high-fidelity optical attenuator, ideal for applications requiring transparency and musicality. Dynamic control is effective but never intrusive, perfect for vocal recordings, acoustic instruments or any critical source.

Flexible routing and precise metering

The EQ/COMP section is fully addressable and can be used in variable order relative to the preamp. The 10-segment LED indicators allow immediate display of level and gain reduction, while the front Hi-Z input also makes it perfect as a high-quality DI.
