ST-MX3

RDL ST-MX3 - 3-Channel Line-Level Audio Mixer with Independent Input Gain

The RDL ST-MX3 is a compact 3-channel line-level audio mixer from the STICK-ON series, designed for professional AV installations, sound reinforcement systems, and signal integration. It provides individual gain control for each input, allowing precise mixing of three line-level signals.

The ST-MX3 accepts balanced or unbalanced signals of varying levels and impedances, offering channel-to-channel isolation and low-noise, low-distortion performance. The line-level output can drive high or low impedance, balanced or unbalanced loads.

With its compact form factor and SupplyFlex™ power input, the ST-MX3 is ideal for expanding existing mixers or serving as a standalone solution in small audio systems.

Functionality:

• 3 × line-level inputs - independent gain control
• mixes signals of different levels, impedances, and configurations (balanced/unbalanced)
• line-level output - drives balanced or unbalanced loads
• input isolation - prevents crosstalk
• power: SupplyFlex™ - floating or bipolar DC

Features:

• compact STICK-ON format
• low-noise, low-distortion performance
• ideal for mixer expansion or standalone use
• suitable for AV, sound reinforcement, and signal integration

The RDL ST-MX3 is a reliable solution for professional audio systems requiring compact, high-quality line-level mixing with flexible input handling.
