Rolls MX54s Pro-Mix Plus Three-Channel Mic Mixer

A three-channel stereo mic mixer, the Rolls MX54s Pro-Mix Plus sends three microphones to a pair of transformer-balanced XLR outputs.

Each XLR input takes a dynamic or condenser microphone and has its own phantom power switch and a low-cut switch that rolls off below 100 Hz. Front-panel level and pan controls place each channel in the stereo mix. The mixer gives up to 60 dB of gain.

The left and right outputs leave the factory set at mic level, and screwdriver trims on the rear panel raise them for line-level gear. A 1/4-inch TRS aux output feeds headphones for personal monitoring or an unbalanced input on a processor or amplifier, and the trims do not change it.

A clip LED lights 3 dB before the circuit clips, beside a power LED and power switch. The MX54s takes two 9-volt batteries, alkaline preferred, or an external power supply.
