Monitor controller ESI MoCo

The ESI MoCo Monitor Controller is a passive studio volume control and monitor switcher designed for precise and transparent audio signal control. Thanks to its fully passive design, the device does not use active components, which guarantees the preservation of the original sound quality without any distortion or signal coloring. It is an ideal solution for home and professional studios where audio purity is critical.

ESI MoCo supports the connection of two independent stereo signal sources. One input is implemented on balanced 1/4" TRS connectors, the second on unbalanced RCA and 1/8" mini-jack, which provides high compatibility with audio interfaces, mixers, players and mobile devices. The output section allows you to simultaneously connect two pairs of studio monitors using balanced XLR, TRS or mini-jack, without signal type conversion - what goes in, goes out.

The front panel features a large, ergonomic volume control with a high-quality potentiometer for precise and smooth level adjustment. An A/B switch allows you to instantly select the active input, while separate output control buttons allow you to independently turn each pair of monitors on or off, making comparative listening much easier.

MoCo’s additional features make it an effective tool for everyday studio work. The Mono button allows you to downmix the signal to mono to check mix compatibility, Mute instantly mutes the sound, and the L/R switch allows you to quickly swap left and right channels. The stylish metal housing and compact dimensions make the controller convenient for placement on your desktop.
