PMC TwoTwo DMC Digital Monitor Controller
Digital Monitor Controller for use with PMC TwoTwo series and more
PMC’s DMC is a sonically transparent hardware digital monitor controller compatible with all of the company’s loudspeakers with digital inputs which includes our twotwo.5, twotwo.6, twotwo.8, IB2S-A, IB2S XBD-A, QB1-A and the QB1 XBD-A.
More than a simple volume control, the DMC accepts two 5.1 and three stereo inputs, and can drive independent 5.1 and stereo loudspeaker monitoring systems. The hardware controls also offer immediate access to configurable bass-management facilities, along with a range of customisable options to optimise your loudspeaker system’s operation for specific working environments, thus sparing users the need to set switches at the rear of individual monitors in the future.
The DMC 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. 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. Discrete stereo and surround outputs are accessed via a rear-panel DMI D-sub connector which breaks out to XLRs via a supplied loom.

NB: Surround input - Stereo-To-Mono mode makes the centre output the sum of L, C and R at –3 or –6dB, LFE at full attenuation or –6dB; Ls and Rs at –6 or –9dB.
