The durable bottom adhesive permits quick, permanent mounting nearly anywhere, or use it with RDL's racking accessories. The ST-MX3 gives you the advantage of a high performance audio mixer with a big PLUS... you can put it where you need it! You can combine modules to build larger mixing systems using whatever combination lines you need!

The ST-MX3 is a 3-channel audio mixer for combining line-level signals to a line-level output.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

Each input features a separate preamplifier circuit which isolates it from the other inputs. A trim pot gain adjustment is provided for each of the three input preamps. Signals from the three preamps are actively summed and fed to the output line-level driver amplifier. The line-input circuit design allows the inputs to accept either balanced or unbalanced signals, of either high or low impedance. The output is capable of driving into either high or low impedance, balanced or unbalanced loads. And each output may be connected in parallel with other ST-MX3 to form a multi-channel mixer to fit nearly any installation.

The ST-MX3 provides:

  • Ultra-low Distortion and Noise
  • Individual Input Level Adjustments
  • Ample Headroom at Operating Level
  • Full Operation in either High or Low ImpedanceCircuits
  • Outputs Short Circuit Protected
  • Positive Connections via Barrier Block, No Audio Connectors to Wire
