The two main parameters of the Phonitor Matrix are Crossfeed and Angle:
• Crossfeed determines the opening angle of the stereo image.
• Angle determines the opening angle of the stereo image.
The “Crossfeed” parameter of the MTC Mk2 is continuously adjustable via the crossfeed control.
The “Angle” parameter is fixed at the studio standard of 30°.
To perfect the listening experience, the level of the sound sources centered in the stereo image must be attenuated when the Phonitor Matrix is activated. The result is that not only the position of all sound sources is correctly located, but also their volume.
For the MTC Mk2, this parameter, which we call “Center” for the Phonitor Matrix, is fixed at a -1 dB attenuation, which is the best choice for an authentic representation of the soundstage.
During conventional listening on headphones, our brain can compensate a certain level of false playback representation – but this is very exhausting and leads to listening fatigue.
The SPL Phonitor Matrix corrects the false representation of the stereo sound image, which makes it much easier to find the right decisions for mixing and mastering engineers.
So nothing stands in the way of a successful and long mixing session on headphones.
On the input side, four analog stereo inputs are provided. The inputs can be switched on or off via switches IN A to IN D.
Multiple selection is possible. All inputs are additive! The MTC Mk2 sums all input signals. A mono signal should always be fed into the left channel to be heard in the phantom center.
The TRS jack inputs A, B and C are ideal for connecting balanced sources, such as a high-quality DA-converter or audio interface.
RCA input D is perfect for connecting a CD player or other sources with RCA outputs as a reference.
Cue Mix – the artist‘s mix
Input C can also be used as a cue mix input. Ideally, the signal that should be sent to a musician/artist as a monitor mix during the recording session should be fed in here.
Once the CUE MIX switch in the headphone section is activated, the signal present at input C is sent to ARTIST headphone output 2 as well as to the CUE OUT output on the rear panel.
The talkback signal is also routed to the CUE OUT output. This way, nothing stands in the way of flawless communication with the artist.
Talkback – for perfect communication
The talkback system of the MTC Mk2 features a high-quality condenser microphone capsule, which is also used in measurement microphones. Therefore the user is rewarded with excellent speech intelligibility.
The talkback system can be activated by pressing the TALK button. This button lights up when pressed. The LEVEL control adjusts the volume of the talkback signal.
The talkback signal is also sent to the output TALK OUT on the rear panel. This signal can be fed into a speaker in the recording room, for example, or back to the DAW for further routing.
The FOOTSWITCH input allows the connection of a latching foot switch or momentary foot switch with TS jack or with TRS jack. This way, the talkback system can also be operated hands-free.
In order to increase the intelligibility of a speaker in the artist monitoring signal during playback, the level of the playback signal at the CUE OUT and the ARTIST headphone amplifier HP2, can be
attenuated by 10 dB when the talkback system is activated. This function is activated using the DIP
switch DIP 1.
An external metering system such as a stereo VU meter can be connected to the METER OUT. The output signal at the METER OUT matches the output signal at the SPEAKER OUT outputs. The level of the METER OUT is not affected by the volume control.
Good sound always starts with the power supply. The MTC Mk2 has a high-quality switched-mode power supply that automatically adapts to all common voltages between 90 V AC and 250 V AC with 50 Hz or 60 Hz.
The new MTC Mk2 now operates with an internal operating voltage of +/-18 volts for the analog audio sections.
The MTC Mk2 can now handle levels up to +22.5 dB and offers about 1.5 dB more headroom than conventional pro audio devices with an internal operating voltage of +/-15 volts.
With all SPL devices we develop not only according to plan, but also by ear. All important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.
