Instead of wasting time fiddling with your system or room, take control of your sound with the MQ112 Environmental Equalizer and spend more time listening to your music.

The quest for perfect sounding audio in your house can be frustrating as virtually no space in a home is designed with sound reproduction in mind. This can lead to constantly tinkering with acoustic treatments, changing speaker placement, or even rearranging furniture (which may not go over too well with other members of the household).

In the relentless pursuit of perfect audio, we understand the frustration of adapting your living space for optimal sound reproduction. With the MQ112, you can make changes to the music itself so that room acoustic problems can be overcome. The results can be stunning and can make even a great sounding stereo system sound even better.

At the heart of the MQ112 lies an 8-band analog equalizer (also called a stereo equalizer) that allows you to increase or decrease the levels of the audio signal at 8 key bands in the 25Hz – 10kHz audio frequency range. Think of it as a sonic sculptor that allows you to finely tune the audio signal. With an impressive ±12dB range of adjustment for each band, you can easily cope with any sound challenge. The MQ112 is the solution you need to enhance or subdue particular instrument ranges or voice types, transforming your listening experience.

The MQ112 Environmental Equalizer does more than just fix room acoustics; it can also breathe new life into older, imperfect recordings. With the master precision of the MQ112, you can target specific frequencies, compensating for deficiencies in vintage tracks and unveiling their hidden brilliance.

The TILT knob, with its subtle tonal balance shift of ±6dB, allows you to customize your sound further. Boost the bass while reducing treble, or vice versa – the choice is yours. The EQ Control knob's IN and OUT settings let you bypass the entire equalizer circuit so you compare the adjusted sound to the original, unaltered version, ensuring you achieve the perfect audio profile. The equalizer can also be triggered IN or OUT using the rear panel’s EQ Control Trigger, giving you seamless control over when the MQ112 works its magic. Also, by using one of the programmable triggers in the audio system's preamplifier, the EQ can be switched IN or OUT depending on input or amplifier choice. Crafted with precision and versatility, the MQ112 boasts remarkably low noise circuits and minimal distortion, harmonizing seamlessly with high-performance audio systems.

The design of the MQ112 Environmental Equalizer is a testament to McIntosh's commitment to timeless aesthetics and high-quality materials. The black glass front faceplate, rotary control knobs, illuminated logo, and custom machined aluminum end caps are signature features of the brand. The back panel's Power Control ports allow for seamless integration with other McIntosh components, making it easy to turn the MQ112 on and off with the rest of your audio system.
