SPL DMC Mastering Console (Black)

Monitor controls are on hand for dim, level compensation, L/R solo, L/R polarity, and mute. All XLR terminations-and there are many of them, rest assured-are secured with Neutrik connectors to ensure durability. At the core of the mastering console is its formidable 120 VDC power rail, which has a palpable effect on the maximum level the circuits can handle. This translates into an extremely low signal-to-noise ratio, a large dynamic range, and much in the way of headroom. Indeed, you can push this system quite hard and loud before noticing distortion.

For a full understanding of the DMCa€™s various sections, please peruse the features section.

Recording Inputs

Four sets of stereo inputs sit at the right of the panel. At the input, pre-recording stage, you can flip the polarity of any input source, sum them to mono, adjust the recording gain, and use the input trim knobs (left and right) to either lower or drive the input into your inserts. The separation of input trims allows you to adjust for any perceived stereo imbalances.

These four input-pairs can be assigned to your DAC, a tape machine, or whatever media device you re mastering from. Pressing any active input button a second time lets you instantiate direct input monitoring, effectively bypassing processing at the monitoring stage, allowing you to compare the original material with the processed path without affecting the recording stage.

Source Inputs

Following the recording input path are four sets of stereo source inputs these can be monitored, but not processed. You can place an external reference source (your DAW s return, a tape machine, a record player, a CD player, etc.). Pressing a source button, prominently placed in the center, will allow you to listen to these source inputs.

Speaker Selection, Headphone Amp Output & Sub

You ll find four speaker outputs for selecting among your various monitors. Three of these (A, B, and C) are stereo, while the fourth (D) is mono. Below these are the on/off buttons for your headphone amplifier and your sub. To link a sub to any speaker button, press and hold both the sub button and the applicable speaker button until they blink. Once connected, you only need to use the speaker buttons to maneuver between, say, full-range monitors and near fields with a sub. Please note, this sub output is full range you ll need external bass management hardware to manage the frequencies of this output. The headphone amplifier output can be set to mute your speakers and subwoofer when engaged. To do this, you only need to press and hold the Phonitor HP Out button until its LED flashes.

Monitoring Section

The monitoring section offers a large knob conveniently labelled Monitoring Level to control the level of the signal in your room. Mono and mute buttons are on hand, as is a -20 dB dim switch, a ± 10 dB monitor level offset for loudness compensation, solo L or solo R channels, and polarity switching for both the left and right signals. This setup lets you compare your source material with the processed result, compensating for level differences in a variety of ways-through the direct input path, with inserts bypassed or engaged, or from the source input. An Auto-bypass switching is on hand to streamline the level-compensation processing, if need be.

GPI Button

A General Purpose Interface button has been offered to use as a switch for a talkback mic, or to activate a recording indicator (a red light, for example), or to control a door s buzzer while you re working. Its signal path is discrete and does not affect audio.

Insert Path

The insert path provided is for connection to external mastering gear, such as compressors, EQs, and stereo processors. It offers balanced, female XLR plugs. It cannot switch the order of your chosen outboard gear it is not a mastering patch bay in this respect, and will need to be paired with an external device capable of switching.
