SPL MTC Mk2 Monitor & Talkback Controller

Manufacturer's Description

The next generation Monitor & Talkback Controller – studio standard redefined.

This classic has been updated with new features adapting it to the demands of modern music production environments.

Advanced source and speaker selection, multiple monitoring modes, an integrated premium talkback system, headphone amplifiers with Phonitor Matrix, an additional input for a dedicated artist mix, and an internal audio operating voltage of +/-18 volts make the MTC Mk2 once again the professional studio standard among monitor controllers.

Full Control

The 45 mm big, massive, milled from aluminum knob for the analog volume control, offers the perfect control range to adjust the monitoring volume intuitively and precisely.

Speakers & Subwoofer

The MTC Mk2 provides three pairs of outputs for stereo speakers and a mono output for a subwoofer.

The respective stereo pairs are selected with high-quality analog switches. Each pair has its individual switch. Thus, multiple selection is also possible. The SUB switch can be used to switch an additional subwoofer on and off. The SUB can be combined with any speaker pair. The subwoofer output sends a mono summed signal with full frequency range. Alternatively, a mono monitor speaker can be connected to the SUB output.

Monitoring modes

MTC Mk2 allows three different monitoring modes.

As a standard, the mix can be monitored in “stereo”. Mono compatibility can be checked in “mono”.

The phase of the signal can be reversed via the phase inversion switch Ø.

A special feature is the third mode – the channel swap function: LR SWAP

Dim and Mute

• Besides the DIM switch for a quick attenuation of the monitoring volume by 10 dB, the MTC Mk2 also offers the option of completely switching off all speaker outputs with the SP MUTE switch. This is useful, for example, when monitoring via a pair of speakers with a subwoofer. So only one switch has to be pressed to turn off this combination.
• If an error occurs in the DAW and a full level noise signal is output from the computer, activating the mute function protects the connected equipment and the hearing from damage.
• In addition to the SP MUTE, there is also an HP MUTE. This deactivates the headphone outputs of the MTC Mk2. (This does not apply to headphone output HP 2 when CUE MIX is activated).
• Perfectly adjusted
• At a regular listening volume (e.g. 83 dB SPL at the monitoring spot), the volume control should be in the one o’clock position. This gives you an ideal control range for listening at quieter or louder volumes.
• If active loudspeakers or power amplifiers are very sensitive, the playback can already be quite loud when the volume control is in the first third of its control range.
• Activating the -6 dB and/or the -10 dB DIP switch (DIP 2 & DIP 3) accordingly attenuates the output level, to use the ideal range of the volume control. If DIP 2 and DIP 3 are set to on, the result is a level attenuation of approximately 13 dB.

The headphone output stage

The MTC Mk2 delivers full headphone sound – twice!

The output stage of the headphone amplifiers is designed as a push-pull amplifier in Class AB mode. The bipolar transistors share the amplification of the positive and negative half-waves, which produces a higher gain and a higher output voltage than in Class A operation, where only one transistor amplifies both half-waves.

The output stage transistors are thermally coupled and thus run particularly coherently, which contributes to a consistent and stable sound image. The power supply has a buffer circuit with low source resistance, ensuring generous current reserves even when operating low-impedance headphones.

Both headphone amplifiers feature the Phonitor Matrix.
(If CUE MIX is active, only the producer hears the headphone signal with Phonitor Matrix. The artist hears their headphone mix without Phonitor Matrix).
