The Digital Monitor Controller consists of two units, the 1U rackmount Digital Monitor Interface (DMI), into which all of your compatible PMC speakers are connected, and the DMC remote control itself, a tabletop unit powered by a cable from the DMI on which all of the speaker selection settings are made and the master volume is adjusted. A user-calibrated reference monitoring level can be defined if required, user-configurable bass management is available for use with subwoofers, and 'Surround to Stereo' and 'Stereo to Mono' downmix functions are accessed from dedicated buttons, in addition to the usual channel Mute, Solo and Solo-in-front functions you'd expect from a monitor controller. Per-speaker level Trim adjustments can be made and stored via the DMC, and up to 340 milliseconds of delay can be applied to individual inputs as desired, with two storable presets.
As its name suggests, the DMC is an entirely digital device, with digital inputs on BNC connectors; all of its processing and routing is carried out by a 32-bit FPGA, giving an internal dynamic range greater than 135dB, with a latency of 0.042 milliseconds. It accepts 24-bit digital signals at sample rates up to 192kHz, and may be synchronised to any of its digital inputs or to an external reference via its sync input, which accepts word clock, DARS, or bi- and tri-level video. The DMI's third stereo input is also fitted with an asynchronous sample rate converter that will accept audio with any incoming sample rate from 8 to 216kHz. The output from this converter may be mixed with any of the DMI's other inputs if required, or output externally as a fixed-level signal. Eight separate outputs are available via the 25-pin D-sub connector on the rear of the DMI, which breaks out via a supplied loom to eight XLRs. Outputs 1 to 3 are direct fixed-level surround outputs for metering or dubbing (L/R, C/Subwoofer and Ls/Rs), output 4 is the direct feed from the sample-rate converted theirs stereo input, outputs 5-7 are the main surround outputs/speaker feeds (L/R, C/Subwoofer and Ls/Rs) and 8 is the main stereo output/speaker feed.
