Description

The ST-VCA3 is used in applications requiring smooth audio level control from a remote control panel, potentiometer or dc voltage (0 to 10 V). Installation in series with the audio input of a power amplifier allows remote control of that amplifier™s level. For installations where it is preferred to keep the audio localized in the rack, audio controls are extended outside the rack from the ST-VCA3. Many installations benefit from avoiding long-term potentiometer wear from audio running through the potentiometer. An ST-VCA3 with external dc control provides virtual immunity from scratchy audio. Audio/video system control units often provide 0 to 10 Vdc control outputs that can directly control audio levels using an ST-VCA3. The ST-VCA3 is primarily intended for line-level attenuation a high quality utility microphone preamplifier is included in the module. If remote control of a microphone preamplifier is desired, such as a wall mounted level control for a microphone jack, the ST-VCA3 may serve as a remote controlled microphone preamplifier.

    Features:
  • Audio Level Control from a DC Voltage
  • Audio Level Remote Control
  • Two Wire with Shield or Three Wire Control
  • VCA with Microphone or Line Level Input
  • VCA with Line-Level Output
  • VCA with LED Metering of Operating Level
