TOA ST-ACR2 Adjustable Delay Volume Controller for Intelligent Audio Signal Control from 5 to 50 Seconds
- The ST-ACR2 is a voice-activated, intelligent audio control module designed to control on/off devices based on line-level audio signals. This Stick-On® module offers reliable performance and easy installation, with a highly customizable response delay, making it ideal for professional audio systems in mosques, meeting rooms, broadcasting systems, and other smart applications.
- The ST-ACR2 is designed to automatically control audio devices via audio signals. The unit acts as a relay that activates when audio reaches a certain level and then automatically shuts off after a delay time that can be adjusted from 5 to 50 seconds. Easily integrated into existing systems thanks to its compact design, this unit is used to control the operation of amplifiers, projectors, or any other system that requires automatic activation upon the presence of audio.
- Contains The volume control unit features two multi-coil controls for sensitivity and delay duration, with an LED indicator for precise threshold adjustment. It also features an Open-Collector Slave output, allowing additional modules to be connected for expanded control.
Technical description:
- The ST-ACR2 audio control unit receives a line-level audio signal and uses it to activate a dual-dual-phase (DPDT) relay. The user can adjust the sensitivity level between -30 dBu and 0 dBu using the SENS control, and adjust the delay required to turn off the relay after the signal disappears using the DELAY control. The unit is equipped with an additional control output that can be used to control other units.
