RDL ST-VCA3 Voltage Controlled Amplifier

Because precision and control are paramount in professional audio applications, the ST-VCA3 Voltage Controlled Amplifier emerges as a powerful and high-quality solution for seamless audio level adjustments. This advanced amplifier is expertly designed to facilitate smooth audio level control from a variety of sources, including a remote control panel, potentiometer, or direct current voltage ranging from 0 to 10 V.

The ST-VCA3's versatility is evident in its ability to be installed in series with the audio input of a power amplifier, thereby enabling remote control of the amplifier's volume level. This feature is particularly beneficial for setups where the audio needs to remain localized within a rack, as it allows for the extension of audio controls outside the rack from the ST-VCA3 unit itself.

One of the standout attributes of this durable amplifier is its virtual immunity to the common issue of scratchy audio, which often results from long-term wear on potentiometers. By utilizing an ST-VCA3 with an external DC control, installations can maintain pristine audio quality over time.

Moreover, the ST-VCA3 is designed to integrate effortlessly with audio/video system control units that provide 0 to 10 Vdc control outputs, directly managing audio levels without the need for additional equipment. While the ST-VCA3 is primarily intended for line-level attenuation, it also includes a high-quality utility microphone preamplifier, adding to its multifaceted capabilities.

For scenarios where remote control of a microphone preamplifier is required, such as a wall-mounted level control for a microphone jack, the ST-VCA3 proves to be an indispensable tool. It can function as a remote-controlled microphone preamplifier, ensuring that audio input levels are consistently balanced and clear.

In summary, the ST-VCA3 Voltage Controlled Amplifier is a robust, versatile, and advanced component that is essential for any professional audio setup requiring precise volume modulation and long-lasting performance. Whether in a desktop or rack mount configuration, the ST-VCA3 by RDL stands as a superior choice for audio professionals seeking reliable and high-quality sound control.
