Grace Design m108 8-Channel Remote Preamplifier and A/D Converter

From 25 years experience of creating acclaimed professional audio products, comes the latest evolution of mic preamplifier design: the m108. With eight channels of transparent, musical mic preamplification, state of the art A/D conversion, multiple digital output formats, and flexible local or remote controlled operation, the Grace Design m108 is a vital addition to any modern audio production environment.

Unrivaled Performance

Based on the acclaimed success of the m802 remote controlled mic preamplifier, the m108 distills the best of these achievements into a sleek, elegant 1U chassis design. Grace Design's transformerless, transimpedance mic preamp design is unmatched in its ability to effortlessly resolve complex sonic waveforms, resulting in recordings of amazing clarity and depth. Integrated A/D conversion delivers digital signals to the workstation that are pure and beautiful. Latest generation s-Lock PLL ensures pristine, jitter free sample clock when clocking from external word clock or Dante clock. And an asynchronous mode USB interface provides the best possible jitter performance when connected to a computer.

Simple Operation

A push-button rotary encoder is used for navigating and operation, with a user interface that is simple and intuitive. Dedicated push-buttons are assigned to core functions: 48V phantom power, phase reverse, channel grouping and meter peak clear. A crisp OLED screen displays complete system information, including channel gain settings, metering, peak status, and the system setup menu.

Powerful Configuration

Out of the box, the m108 is ready to go as a stand alone mic preamp / ADC. With integrated serial or MIDI control, the m108 can be configured in large channel-count remote systems, with control from the existing m802 hardware remote control unit, from Pro Tools, the forthcoming m108 control app, or even simply over ethernet with any modern web browser. And an optional DANTE™ interface is provided for network audio configurations. The m108 control protocol is backward compatible with the m802 so you can add m108’s to an existing m802 system.
