You Need The ST-MX3!
The ST-MX3 is part of a group of products in the STICK-ON series from Radio Design Labs. The durable
adhesives provided with the ST-MX3 permit permanent or removable mounting. Numerous available
mounting accessories, brackets, rack-mount and table top chassis are optionally available to facilitate any
system. 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, and you can combine modules to build larger mixing systems using whatever
combination you need!
APPLICATION: The ST-MX3 is a three-channel audio mixer for combining line-level signals to a
line-level output. Individual level control is provided for each input. Each input features a separate
preamplifier circuit, which isolates it from the other inputs. A single-turn trimmer 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 of the ST-MX3 allows the inputs to accept either
balanced to unbalanced signals, or either high or low impedance. The output is capable of driving into
either high or low impedance, balanced or unbalanced loads. Each output may be connected in parallel
with other ST-MX3s, or ST-UMX3s to form a multi-channel mixer to fit nearly any installation! The ST-MX3
features amplifier circuitry which produces the unsurpassed pure clarity for which Radio Design Labs
products are known! Some features are:
 Ultra-low Distortion
 Ultra-low Noise
 Input Levels Individually Adjustable
 Ample Headroom at Operating Level
 Full Operation in either High or Low Impedance Circuits
 Outputs Short-Circuit Protected
 Positive Connections via Barrier Block, No Audio Connectors to Wire
The audio clarity, low noise, low distortion and versatility make this module ideally suited to a wide variety
of demanding audio applications. Use this module in conjunction with other RDL modules as part of a
high quality, flexible audio/video system.
