Grace Design m108-CRO - 8-Channel Microphone Preamplifier (with CR Option)

From 25 years experience of creating acclaimed professional audio products, comes the latest evolution of Grace Design's 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 m108 is a vital addition to any modern audio production environment.

Pre-Installed CR Control Room Output Module
The CR (Control Room) Output Module provides an additional set of 1/4" TRS balanced outputs suitable for playing back via a stereo monitor system. These outputs are controlled by the front panel VOL/MUTE output level control. To facilitate interfacing with diferent amplifer / powered speakers systems, the CR Output Module features selectable output gain ranges. The CR Out module ships from the factory in Low Gain mode. This should be sufcient for most powered monitor systems. A volume setting in the range of 60-90 is normal. If more gain is needed, the CR Module can be confgured for High Gain Mode.

Features:

• 8 channels of balanced analog preamp outputs
• 8 channels of transparent, musical mic preamplifier
• Wide gain range: -6 to 69dB
• Ribbon mic mode
• 8 channels of 192kHz ADC outputs via AES, ADAT (4ch SMUX) and USB Class 2
• External Word clock in and out
• Reference DAC and headphone amplifier for low-latency monitoring of channel pairs or USB playback from a computer
• Channel 1 / 2 HI-Z inputs on front panel
• High contrast, wide viewing angle OLED display for all system parameters and setup menu
• Combination RS 485/422 serial / MIDI ports for control from existing m802 RCU or Protools™
• Control App (Win and Mac, coming soon) can control up to 96 channels over Ethernet
• Simple web browser control built in, works with all modern browsers including iOS and Android
• RJ45 Ethernet port for network control
• Expansion slot for optional Dante, Digilink, or Ravenna (AES67 / ST2110) audio card
• Cooling fan for reliable operation in the harshest environments
• Built in 100-240VAC universal AC power supply
• 5 year transferable warranty
• Made in the USA

UNRIVALED PERFORMANCE
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
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.

EVOLVED I/O CAPABILITY
The m108 is capable of connecting to a wide array of equipment with modern audio formats. Standard output connectivity includes balanced analog, AES3, ADAT and USB. The option slot allows users to add cards for Digilink, Dante or Ravenna (including ST2110 / AES67). Additionally, a Control Room Output (CRO) card can be installed in the option slot, allowing the m108 to act as a monitor controller for a pair of studio monitors.

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. See the m108 owner’s manual for complete details.
