GRACE DESIGN M-802 8-CHANNEL MIC PREAMP

The m802 can be controlled directly from Digidesign® ProTools|HD® systems, compatible control surfaces and many other MIDI devices. Additionally, the m802 can be controlled by a wide variety of MIDI mappable devices, making it easily integrated into a wide variety of remote recording situations.

DPA® 4000 series 130V microphones are widely regarded as some of the finest reference-quality microphones available. But with a 130V power requirement, microphone preamplifier options have been limited. The m802 is an excellent compliment for DPA® microphones by adding a 130V power option, available on a per channel pair basis.

The signal path of the m802 has been updated to be fully balanced from start to finish, resulting in a noticeable dynamic range improvement. Next, output current has been increased so that even longer audio cable runs can be achieved without signal loss. Also included is a provision for a high definition 24-bit/192 kHz converter card in the future.

The Remote Control Unit (RCU) has been completely redesigned to provide greatly improved ergonomics and system control. The updated RCU now offers dedicated individual channel select switches and a highly visible blue LED numeric display for channel gain settings. The RCU will effortlessly control a system of eight m802s from up to 1000’ away. And both the RCU and the m802 now come with a high contrast, easy on the eyes white backlight LCD.

The m802 system resides in the same bold, stainless steel chassis as the m series monitoring systems, which is quite rugged and easy to maintain.
