- Control Switching from Audio Signal
- Switching from Mic OR Line Signals
- Silence Sensing
- Precise Threshold Adjustment
- DPDT Switching Contacts
- Open-Collector SLAVE Output
The ST-ACR1 module is designed to switch on LINE-LEVEL sources. Its relatively short release delay time makes it the optimum choice for voice applications.
- 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
