Radio Design Labs' ST-VOX1 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. The ST-VOX1 is specifically designed to switch reliably on voice signals.
When used in intercom or talk back 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 RDL's STM-1 preamp. The unbalanced output from the STM-1 can be used to trigger the ST-VOX1, while the STM-1 balanced output is used for the audio feed.
The ST-VOX1 releases very quickly, but holds on through very short pauses in syllables common to speech. These time constants allow the design of a communications system yielding comfortable two-way conversation.
Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product. Please see the "Accessories" tab for more information on the PS-24AS power supply.
