The RDL ST-ACR1 is an audio controlled relay and part of RDL's "Stick-On" series of equipment. It is designed for reliable operation and quick, easy installation. The ST-ACR1 is designed to switch line-level signals. Two multi-turn trimmers are provided, one for audio input sensitivity, and one for delay control.

The unit can be triggered from signals between -30 to 0 dBu, and an indicator LED allows accurate adjustments of the input sensitivity. The delay control sets the time delay for relay release when the audio drops below the pre-set threshold. The delay can be set from 0.5 to 5 seconds.

Small, compact unit can be easily mounted almost anywhere
