Grace Design m905 Black

Product description

Text by Grace Design

The m905 has been engineered from the ground up to provide unrivaled audio performance, with a powerful, comprehensive, and intuitive feature set. The main audio and power supply circuitry is housed in a 2U rack mount mainframe, while system control is managed by a sleek new ergonomic desktop remote control unit (RCU). The RCU is a combination of dedicated hardware and a color, graphical LCD. The primary monitoring features are accessed via hardware switches and a rotary encoder. All system information is presented on the LCD and illuminated switches. This hybrid design provides the solid feel and function of traditional hardware, with the added power and flexibility of a graphical user interface.

Some of the m905 key features include:
- analog inputs: balanced, unbalanced, cue loop and talkback mic
- digital inputs: 2x AES3, S/PDIF, TOSLINK, and ADAT (selectable in 4 pairs or 2 pairs in sMUX)
- asynchronous Class 2 USB input supports 24-bit/192 kHz
- mastering grade DAC circuitry with configurable de-emphasis filtering
- s-Lock dual-stage PLL (Phase Lock Loop) for ultra-low jitter clock regeneration
- reference headphone amplifier circuitry (essentially, a built-in m903) with one output on the mainframe unit, and one on the RCU
- Dr. Jan Meier's crossfeed circuitry for headphone monitoring use
- sleek new ergonomically designed RCU with hardware switches, large level/edit encoder, and color, graphical LCD
- LCD shows inputs, outputs, (these can all be named by the user) levels, SPL and DAC status, plus a powerful calibration menu
- real-time SPL metering that's sourced by the built-in, omnidirectional RCU microphone - includes level, peak, fast and slow modes and A & C weighting
- precision .5 dB step level control for speakers and headphones
- dedicated Mono, Dim and Mute switches
- mono mode can be set to L+R summed, L only in both channels, or R only in both channels
- (3) available stereo speaker outputs…(2) configurable as 2.1
- multi-mode Sub/DAC/Meter outputs
- Sub output mode for stereo or multiple mono subwoofer outputs
- DAC output mode for a fixed DAC output fed by the currently selected digital inputs, with level calibration
- Meter output mode fed by selected analog or digital input signal, with level calibration
- future firmware upgrades will be available via download on the USB port
- Limited 5 Year Warranty
