The STACR2 is an Audio Controlled Relay in the STICKON® series. These products are designed for quick, convenient installation, and reliable operation in a variety of control applications. The STACR2 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 STACR2 is from 5 seconds to 50 seconds.
