SPL DMC - Mastering Console (Black)

The DMC is the heart of the mastering studio. The converters, the players, the DAW, the recorders and the speakers are connected to it. The audio quality of the console is therefore crucial. Like all devices of the mastering series, the DMC works on the unparalleled 120V technology.

Inputs / Sources
Audio signals that shall be processed are connected to the Inputs and audio signals for comparison or playback are connected to the Sources. Four stereo inputs pairs are available for each. Each input channel can be switched on/off, phase reversed and trimmed in 0.25 dB steps. A stereo input can be switched to mono.

The large potentiometer for the recording gain allows sensitive gain rides. If it is not used, it should not be activated. This keeps the entire control stage outside the signal path.

Monitoring / Inserts
Three pairs of speakers can be operated for full-range, mid-field and near-field monitors. Speakers D is for a mono loudspeaker.

Preferably a Phonitor headphone amplifier is connected to the Phonitor HP Out, whereby it can be programmed whether the loudspeaker is automatically switched off during headphone operation or not. The same applies to the subwoofer. It can be programmed with which monitor it is paired and activated together.

The insert return can also be trimmed in 0.25 dB steps to compensate for the finest level differences after an insert chain. The Hermes Mastering Router is preferably connected to the inserts, with which up to eight stereo processors can be connected and freely routed and stored.

In the monitoring section, each loudspeaker channel can be solo'ed and phase reversed.

The large monitoring level potentiometer has an illuminated indicator so that the monitor level can be easily assessed even from a greater distance.

A loudness compensation (+/- 10 dB) can be activated. Alternatively it can be linked to the Insert, Sources or Inputs switches allowing loudness compensation at any stage.

DMC with MC 16
The DMC can be linked to the MC16 for surround and immersive audio applications. Dolby Atmos® or Auro 3D® projects can also be realized. The MC16 is the world's first analog 16 channel monitoring controller.

Mastering studios often use the L/R speakers and subwoofer for stereo and multi-channel monitoring. The combination of DMC with MC16 makes it unnecessary to replug these speakers.

Pressing the Speaker A button for two seconds transfers the volume control of L/R and Sub to the MC16 and pressing it again brings it back to the DMC. In this way, stereo and surround projects in a studio can easily be performed one after the other.

The 120V technology
The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps.

The highest possible audio quality requires the highest possible audio operating voltage. The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.

The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.

By the way, the "120V" in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.

The mains voltage from the mains power socket is transformed to the required secondary voltage in the device's internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
