Description

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

The finest sounding, most capable mic preamplifier we have ever create.

Unrivaled Performance

Based on the acclaimed success of our m802 remote controlled mic preamplifier, the m108 distills the best of these achievements into a sleek, elegant 1U chassis design. Our 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 our existing m802 hardware remote control unit, from Protools, 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 to an existing m802 system.Â

Grace Design Remote Control Software

The m108 Control Software application allows for control of up to 12 m108 preamplifiers using the Ethernet control port on the m108. Each preamplifier in the system will have a dedicated control panel for operating the microphone preamplifiers, ADC, and clocking parameters. The control application allows for the creation of channel groups as well as saving and recalling presets. The application runs under Windows (7,8.1,10) and Mac OS (10.11). For control of the m108 via Android or iOS use the m108 web interface.

m108 Web Browser Control

The m108 has a built-in web browser controller allowing remote control from most web enabled Mac, Windows, iOS and Android devices. This control has been optimized for Chrome, but will operate on most modern web browsers (excluding Internet Explorer). This makes control of any m108 on an ip LAN as simple as entering the m108's IP address into the browser's navigation window, and the web browser control from that preamp will automatically load and connect.
