The Grace Design m108 is a rack-mountable eight-channel preamplifier and ADC providing connection points for eight microphones on the rear panel, as well as two Hi-Z instrument inputs on the front. With this unit, you can either achieve analog amplification through its transformerless, transimpedance design, or utilize its on-board conversion stages to route signal into your DAW in a variety of digital output formats, including AES, ADAT, and USB. The unit is also remote-controllable, able to receive commands from Grace's m802 remote control unit or Pro Tools via on-board 485/422 serial / MIDI ports.
Its push-button rotary knob handles the navigating and instantiation of various operations, though dedicated push-buttons are assigned for essential needs, such as 48V phantom power switching, phase reversal, channel grouping, and clearing peaks on the meter. A headphone output with integrated headphone amplifier allows for low-latency monitoring of assignable channel pairs, or for listening to USB playback from a source-computer.
The m108 features word clock I/Os and optional expansion slots to interface with Dante networks. Furthermore, this device is compatible with m802s, so you integrate this unit into any existing m802 system
