Lake People MC50 – 19″/1U professional monitor controller with two balanced XLR inputs, one balanced slave (thru) output, two balanced line outputs for power amps/active speakers, and a true balanced headphone amplifier (four power stages) featuring front-panel Pre-Gain and variable X-Feed crossfeed. Comprehensive monitor functions include Solo L/R, Channel Swap, Mono and right-channel Phase Reverse, plus dual illuminated VU meters with adjustable brightness and an ALPS RK27 41-detent master volume.

Inputs can be selected individually or summed; output routing lets you activate headphones and/or speakers separately, with global Mute and automatic protection (delayed HP coupling, DC and temperature monitoring). Front-panel headphone I/O includes two 6.3 mm jacks (unbalanced) and a 4-pin XLR (balanced) to exploit the amplifier’s four power stages.
