Description

Each of the ST-ACR products is an Audio Controlled Relay in the STICK-ON® series. These products are designed for quick, convenient installation, and reliable operation in a variety of control applications. The ST-ACR-1M is designed to switch on low-level sources, such as microphones or mic-level sources.

Two multiturn trimmers are provided. The SENS potentiometer adjusts the audio input sensitivity. A threshold LED facilitates accurate adjustment. The module can be set to trigger on signals between -65 dBu and -20 dBu. The DELAY control sets the time required for the relay to release when the audio drops below the threshold. The adjustment range is from 0.5 seconds to 5 seconds.
