APPLICATION: 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 LINE-LEVEL sources, and has a longer release delay time making it the optimum choice for most music applications. The ST-ACR2 is widely used as a Silence Sensor.
- 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.
