MC16

16-Channel Mastering Monitor Controller

The MC16 is designed to monitor surround and immersive audio projects (Dolby Atmos®, Auro 3D®, etc…) in the analog domain, offering the same unrivalled quality as 120V stereo monitoring.

16 Speakers

Sixteen buttons are used to activate the corresponding loudspeakers.

 

The 16 inputs of Input 1 and Input 2 are routed directly to the outputs to ensures that an output routing of a DAW session always matches the routing in the MC16.

 

The buttons allow you to insert a label with the exact name of the loudspeaker.

MC16 offers two 16-channel inputs to quickly compare a current project with a reference production.

Monitor Level

 

This analog potentiometer is used to adjust the monitor level. We developed a 16-level potentiometer, with which we could realize the volume control in the analog domain, because we did not want to accept a digital control, which is afflicted with resolution deficits and limited dynamic range.

Presets

 

You can save speaker setups to three memory locations. So you can quickly call up a 5.1 or an 11.1 or a 9.1.6 configuration.

 

In solo mode, three more memory locations are available with the same keys. For example, you can create solo groups for all front speakers and all ceiling speakers and all rear speakers.

 

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.

The idea for SPL 120V technology and the SUPRA operational amplifier based on this technology were developed in the 1990s by SPL founder and chief developer Wolfgang Neumann.

 

With the goal of building the best mastering console ever, this basic technological philosophy then took shape for the first time – thus the SPL MMC1 Mastering Console for Galaxy Studios saw the light of day in 2000.

The outstanding sonic and technical features quickly got around in the scene – so further orders were not long in coming.

Besides the MMC 1, another legendary product with 120V technology was created with the PQ, the “King of Parametric Equalizers”.

Since that time, 120V technology has been the foundation for all SPL premium products. Meanwhile, not only for mastering applications, but also for the, studio or hifi use.

 

Comparison

Most audio devices work with an internal operating voltage of +/-15 volts and can thus process a maximum input level of +21.5 dBu. If a DAC, for example, has an output level of +22 dBu at 0 dBFS, level peaks of the music material would already cause overloads in the input stage of the device.

 

All components in the audio device often operate at their limits. The result is an unsteady sound that causes stress and faster ear fatigue.

SPL devices with 120V technology can handle input levels of +32.5 dBu thanks to the higher internal operating voltage of +/- 60 volts – thus offering 12 dB more headroom. All components consequently operate continuously in the optimum operating range. The result is a very pleasant, natural and relaxed sound experience. So you can enjoy your music in every detail.

 

These diagrams clearly show the superiority of the 120V technology in comparison to other circuits with lower, common operating voltages.

In the realm of professional audio mastering, precision and clarity are non-negotiable. The SPL Audio MC16 Mastering Monitor Controller is engineered to meet the exacting standards of audio professionals who demand flawless signal integrity and unparalleled control over their monitoring environment. Whether you are finalizing a mix, mastering tracks for commercial release, or conducting critical listening sessions, the MC16 ensures that every nuance of your sound is faithfully reproduced, enabling you to make confident, informed decisions.

One of the most significant challenges in mastering is maintaining a pure and uncolored audio signal from source to output. The MC16 addresses this with its exceptionally high maximum input and output gain of 32.5 dBu, which means it can handle hot signals without distortion, preserving the original audio fidelity. The input impedance of 20 kΩ ensures compatibility with a wide range of analog gear without signal loss, while the low output impedance of 75 Ω guarantees that the signal remains robust and consistent when feeding your studio monitors. This meticulous attention to signal path detail translates to cleaner, more accurate monitoring, allowing you to hear your mix exactly as it was meant to be heard.

The SPL MC16’s internal linear power supply, featuring a shielded toroidal transformer, is designed to minimize electromagnetic interference and noise. This results in an ultra-clean power source that supports the unit’s impressive noise floor of -102.4 dB (A-weighted). In practical terms, this means the controller adds virtually no background noise to your signal, an essential factor when working with dynamic and delicate audio material. Furthermore, the device’s common mode rejection of -82 dBu and a crosstalk figure of -100 dBu at 1 kHz ensure that unwanted hums, buzzes, or signal bleed between channels are effectively eliminated. This level of electrical performance preserves the integrity of your stereo image and dynamic range.

With a frequency response extending from an ultra-wide 4 Hz to 300 kHz (-3 dB), the MC16 guarantees that no part of the audio spectrum is lost or altered. Although human hearing typically ranges up to 20 kHz, this extended range reflects the device’s commitment to maintaining phase accuracy and transient response, ensuring that the entire audio signal is handled with precision. Total harmonic distortion plus noise (THD + N) surpasses 112 dB at +24 dBu, meaning the MC16 operates with near-perfect transparency, a critical attribute for mastering engineers who require the highest level of sonic accuracy.

Physically, the SPL MC16 is thoughtfully designed for professional studio environments. Its dimensions are a standard 482 mm wide, 88 mm high, and 300 mm deep, fitting comfortably into a 19-inch rack while weighing 8.4 kilograms (approximately 18.5 pounds). This robust build not only ensures durability but also reduces vibrations and external interference, which can compromise sonic quality. The selectable mains voltage options (230 V AC / 50 Hz or 115 V AC / 60 Hz) and corresponding fuses provide flexibility for global use, making it a versatile choice for studios worldwide.

In practical terms, the MC16 is ideal for mastering engineers, mixing professionals, and audio enthusiasts who require precise monitor control and signal purity. Its high-quality analog inputs and outputs allow seamless integration with a variety of studio setups, including analog summing mixers, digital audio converters, and high-end monitor speakers. The device’s refined control over gain staging and signal routing empowers users to conduct critical listening sessions with confidence, ensuring that mixes translate perfectly across all playback systems.

In summary, the SPL Audio MC16 Mastering Monitor Controller is an indispensable tool for audio professionals seeking uncompromising accuracy and reliability. Its advanced analog circuitry, exceptional noise performance, and versatile design make it a cornerstone of any mastering workflow. Investing in the MC16 means investing in the integrity of your audio, giving you the assurance that your final product will meet the highest standards of sonic excellence. With the MC16, every detail of your sound is under your control—precisely as it should be.
