Grace Design m802 Remote Microphone Preamp
This remote controllable, high fidelity 8-channel microphone preamplifier is extremely transparent and musical. Its full featured stand-alone hardware RCU will seamlessly control up to 64 channels (a system of eight m802s) from distances up to 1000’. All preamplifier functions, including gain, phase, and 48V phantom are instantly accessible and adjustable. These settings can then all be stored into preset locations and instantly recalled.
The unit can also be controlled directly from DigiDesign® ProTools|HD® systems, compatible control surfaces and other MIDI devices, making it easily integrated into many different remote recording situations.
