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.

Anywhere You Need...
  • Control Switching from Audio Signal
  • Switching from Mic OR Line Signals
  • Silence Sensing
  • Precise Threshold Adjustment
  • DPDT Switching Contacts
  • Open-Collector SLAVE Output
  • High-impedance bridging input connects across any audio line
  • Input may be connected to either balanced or unbalanced sources
  • Multiturn sensitivity adjustment permits precise threshold setting
  • Multiturn DELAY control adjusts relay release delay
  • Bandpass filtering yields triggering on characteristic audio spectrum
  • SLAVE open-collector terminal allows additional relays to be added for more contacts (Radio Design Labs' ST-LCR1 or ST-LCR2)
  • SLAVE terminal may be used with remote switch to manually override the control circuit and turn on the relay

NOTE: Power supply is required.
