Everything this camera needs, matched by our specialists. Silarius picks first.
The ST-VOX1 is an Audio Controlled Relay in the STICK-ON® series. When used in intercom or talkback applications, the ST-VOX1 may be triggered directly from an unbalanced microphone. In many such installations the microphone or other audio source must be preamplified, making the ST-VOX1 an ideal mate to work with the STM-1 preamp. Key capabilities include: Switching Controlled by Voice Signal; Switching from Mic or Line Level Signals; and Precise Threshold Adjustment.
