Rolls MX122 MiniMix Pro Mic/Source Mixer

The Rolls MX122 MiniMix Pro is a compact and reliable five-channel audio mixer. It’s suitable for musicians who need to mix stereo keyboards, sound modules, and other line-level sources with a single microphone.

Channel 1 is a dedicated microphone input with a 3-pin XLR connector and a mic trim pot. Channels 2 through 5 feature 1/4″ inputs divided into stereo pairs, though they can also accept mono signals.

Two 1/4″ outputs are provided on the rear panel for stereo connections, but you can also monitor with headphones using the front panel jacks. For this purpose, a 1/4″ and a 3.5mm output are supplied. Master output knobs are supplied for overall level and phone/aux level. With this mixer, you can combine a microphone signal with four stereo or mono signals, with level and pan controls over each channel. A power supply is included.

Microphone Input
Channel 1 features a XLR microphone input with 12VDC phantom power, selectable via the phantom power jumper on the rear of the unit.

Stereo Line Inputs
