Grace Design m905 Reference Monitor Controller (Silver)
EAN: 823821109055
The silver Grace Design m905 is a reference monitor controller and high-quality digital-to-analog converter, designed to deliver mastering-quality monitoring to your home or professional studio.
Featuring balanced and unbalanced analog inputs, and AES, S/PDIF and ADAT digital inputs, the m905 allows you to switch between a variety of input sources. Additionally, the unit has three stereo pairs of balanced speaker outputs with two assignable mono sub outputs, giving you a versatile selection of monitoring options when mixing or mastering.
Features:
Balanced and unbalanced analog inputs
CUE & talkback mic
2x AES3 , 1x S/PDIF, 1x TOSLINK, ADAT (selectable in 4 pairs, or 2 pairs in S/MUX), USB & DSD128 (5.6448 MHz)
Audio circuitry designed for transparent playback
Asynchronous Class 2 USB playback supports up to 24 bit / 192 kHz
Mastering quality DAC circuitry with configurable de-emphasis filtering
s-lock dual-stage Phase Lock Loop for low jitter clock regeneration
Hybrid RCU with hardware switches, large level encoder, and graphical LCD
LCD display shows input, level, output, SPL, and DAC status plus a full calibration menu
RCU includes built-in microphone for talkback and onboard SPL meter
SPL meter features include level, peak, fast and slow modes, and A& C weighting
Precision 0.5 dB step level control for speakers and headphones
Reference headphone amplifier circuitry, with outputs on both the RCU and ACU
Dedicated mono, dim, mute, and sub mute switches
Mono mode can be set to L+R summed, L only in both channels, or R only in both channels
L solo, R solo, L-R, and sub solo modes available
3 available stereo speaker outputs, with 2 assignable mono sub outputs (or single stereo sub output)
Multi-mode SUB / DAC / METER out
SUB out mode for stereo or multiple mono subwoofer outputs
DAC out mode for a fixed DAC output fed by the selected digital input
METER out mode fed by selected input signal (digital or analog), configurable with a fixed level or to follow the monitor level
Detachable RCU tilt base
