Each of the ST-ACR products is an Audio Controlled Relay in the group of STICK-ON series products by Radio Design Labs. These products are designed for quick, convenient installation, and reliable operation in a variety of control applications.
This module is designed to switch on LOW-LEVEL sources, such as microphones or mic-level sources. Its relatively short release delay time makes it the optimum choice for voice applications where the source has not been preamped up to a line level.
