The m802 from Grace Design is an eight channel, remote controllable microphone preamplifier designed for unmatched audio performance with massive headroom and ultra-wide bandwidth. The unit can effortlessly resolve even the lowest level ambient information, resulting in a sonic picture of absolute clarity and detail, which serves to capture the essential character of the music being recorded.
The m802 system consists of an eight channel preamplifier chassis, a power supply chassis and an optional remote control unit. Additionally, the preamp can also be controlled directly from Digidesign ProTools HD systems, compatible control surfaces and many other MIDI devices.
The preamplifier chassis contains eight audio amplifier PCBs, a micro controller PCB and a front panel control interface. For remote control communications, the preamplifier is equipped with two Philips I2C bus connectors (proprietary D-sub 9 pin) and MIDI in and out connectors. The signal path is fully balanced from start to finish, resulting in generous dynamic range, while high current output drivers enable long cable runs without signal loss.
An additional set of eight channel balanced outputs are included for sending signals to a secondary recorder, workstation or console. The use of an external DC power supply unit ensures that no power line interference can compromise the performance of the sensitive microphone amplifier circuits.
