The RDL ST-VCA3 Voltage Controlled Amplifier is used in applications requiring smooth audio level control from a remote control panel, potentiometer or dc voltage (0 to 10 V). Installation in series with the audio input of a power amplifier allows remote control of that amplifier's level.

The RDL DS-HA1A Format-A Stereo Headphone Amplifier is a two pair receiver and audio headphone amplifier compatible with RDL Format A twisted pair products. Each HA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack fed from a Format-A sender.

The RDL ST MX2 2 Channel Audio Mixer is used in any application requiring mixing of two audio sources. A mic may be mixed with a line-level music source. Two mics may be mixed to feed the mic or line level input of a power amplifier.

The RDL 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.
