The RDL ST-VOX1 is a compact voice-activated audio controlled relay in the "Stick-On" line of products. The ST-VOX1 can be triggered directly from an unbalanced microphone when used in intercom or talkback applications. In many of those applications, the microphone signal must be preamplified, making the ST-VOX1 an great partner to the STM-1 preamp. The ST-VOX1 can also accept line-level signals and a slave terminal allows additional relays to be added.
