Overview
The ST-MX3 is a line-level mixer module in the STICK-ON Series of products. It provides audio mixing of three line-level inputs with individual input gain adjustments. The line-level output is capable of driving either high or low impedance, balanced or unbalanced loads.
The ST-MX3 operates from ground-referenced floating or bipolar dc power.
For installations with microphone level inputs, use the ST-UMX3 Universal Audio Mixer.
