A Feature-laden Monitor Controller with Talkback

The SPL MTC Mk2 takes everything that made its predecessor a hit, and takes it to a higher level. This monitor controller boasts a solid-feeling Volume knob, plus three monitoring modes, Mono and Dim switches, individual Mute switches for studio monitors and headphones, and mid-side monitoring. The MTC Mk2 contains enough I/O for three pairs of studio monitors, a sub, and four stereo input sources. A dedicated meter output and studio monitor level calibration ensure top-shelf sound in every application. The MTC Mk2’s excellent talkback system includes a built-in microphone, plus a dedicated Level control, automatic cue mix attenuation, and hands-free control via a footswitch. You also get a top-of-the-line headphone amplifier with two headphone output jacks and dedicated level controls for each output. To top it off, the MTC Mk2 includes SPL’s vaunted Phonitor Matrix technology for speaker-like performance when listening on headphones. The MTC Mk2 includes +/-18V internal operating voltage, through-hole technology on all important components, and a high-quality switched-mode power supply.

Take full command of your monitoring chain

The MTC Mk2 gives you full control over your monitoring chain. A solid-feeling aluminum knob provides easy, intuitive volume adjustment. Three monitoring modes ensure maximum flexibility. Stereo monitoring — complete with a mono compatibility check — is the standard. You can monitor a reverse-phase version of your mix via the Ø switch. You can also audition a reverse stereo version of your mix via the LR Swap switch — a must-have for film work. What’s more, by using the Mono and Ø switches in concert you can monitor the mid and side portions of your mix individually. The MTC Mk2 also includes a Dim switch, plus separate Mute switches for your speakers and headphones.

Enough I/O for any studio

When we took the SPL MTC Mk2 for a test drive here at Sweetwater, we were impressed with its robust I/O. You get enough outputs for three pairs of stereo speakers, along with a mono output for a subwoofer. Each pair of outputs has a dedicated on/off switch, and there’s a separate Sub switch as well. And since the subwoofer output sends a full-range signal, you can also use it to connect a single mono monitor speaker. You get four stereo inputs, each with a dedicated on/off switch. Inputs A–C features balanced TRS jacks, while input D includes an RCA input for consumer playback devices. You can also use input C as a cue mix input. A dedicated meter output and studio monitor level calibration is also included.

Easy communication with the artist

The MTC Mk2 boasts an impressive talkback system, complete with a built-in condenser mic. The built-in microphone features a top-shelf design derived from the technology employed by measurement microphones. The talkback system is activated via a Talk button, which lights up when pressed. You also get a dedicated Level control for the talkback signal. The talkback signal is routed to the Talk Out jack on the MTC Mk2’s rear panel, where it can either be fed into a speaker in the recording room or sent back to your DAW. Engaging the talkback system automatically attenuates the artist’s cue mix, and the attenuation is fully adjustable. To top it off, a Footswitch input enables hands-free use of the MTC Mk2’s talkback system.

Top-shelf sound for your headphones

If you demand top-quality sound from your headphones, you’re in luck. The SPL MTC Mk2’s headphone amplifier boasts a push-pull, Class AB design, which yields higher gain and higher output voltage than Class A amplifiers. The amplifier’s output stage transistors are thermally coupled for consistent operation and a stable sound image. Beyond that, the MTC Mk2’s buffered power supply facilitates great sound, even with low-impedance headphones. The MTC Mk2 includes two headphone output jacks, each with a dedicated level control.

Power Supply

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.

In any professional audio environment, precise control over monitoring and communication is essential for achieving the highest quality results. The SPL MTC Mk2 Monitor & Talkback Controller is designed to meet the demanding needs of studios where accurate audio playback and seamless communication between engineers and artists are critical. Whether you are mixing, mastering, or tracking, this controller provides the reliability and flexibility required to streamline your workflow and ensure every detail in the sound is heard clearly.

One of the core challenges in studio monitoring is managing multiple audio sources and speaker setups efficiently without compromising signal integrity. The SPL MTC Mk2 addresses this by offering four stereo input channels, allowing you to switch effortlessly between different audio sources such as DAWs, outboard gear, or external hardware. This means you can compare mixes or reference tracks instantly without the hassle of reconnecting cables. Additionally, the controller supports three stereo monitor outputs alongside a dedicated subwoofer output. For the user, this means you can switch between different speaker pairs and a subwoofer with ease, enabling precise monitoring tailored to the acoustics of your space or the requirements of the project.

Connectivity is another area where the SPL MTC Mk2 excels. It provides six 1/4″ analog inputs and one dual stereo RCA input, offering compatibility with a wide range of professional and consumer audio equipment.

Communication between the control room and recording booth is made effortless thanks to the integrated talkback functionality. The SPL MTC Mk2’s talkback system uses a dedicated footswitch input, allowing engineers to engage the talkback microphone hands-free, which is particularly useful during live recording sessions or critical listening phases. This feature ensures clear and immediate communication without interrupting the flow of the session, minimizing downtime and enhancing productivity.
