Description
The ST-ACR2 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-ACR2 is designed to switch on line 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 -30 dBu and 0 dBu. The DELAY control sets the time required for the relay to release when the audio drops below the threshold.The delay adjustment range for the ST-ACR2 is from 5 seconds to 50 seconds.-
