The Grace Design m108 8-Channel Remote-Controlled Mic Preamplifier / ADC with DigiLink Upgrade Card Kit from B&H adds a DigiLink upgrade card for use with Avid Pro Tools HD systems to this rackmountable eight-channel preamplifier and ADC. The card must be installed by the user in the unit's expansion slot.
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

The Grace Design DigiLink Option Module for m108 Microphone Preamplifier / ADC (Upgrade) lets you connect your m108 to an Avid Pro Tools HD Accel, Pro Tools HDX, or Pro Tools | HD Native interface. The module features two Mini-DigiLink connectors, one Primary port, and one Expansion port, which emulate the the Avid HD I/O interface. Because the m108 is an 8-channel input and 2-channel output device, these ports allow two m108s to be connected together to emulate one Avid HD I/O with a standard configuration of 1 ADC card, 1 DAC card, and one digital I/O card.
