AUDAC VC3208 Rotary volume control

The AUDAC VC3208 Rotary volume control is a flush-mount wall controller designed for voltage-controlled amplifier systems that accept a 0–10 V control signal. Housed in a white, low-profile enclosure compatible with standard 45 x 45 mm installation frames, the VC3208 provides smooth manual adjustment of audio level via a rotatable potentiometer dial. Connections to the amplifier are made with a pluggable terminal block over twisted-pair CAT5e (or better) cabling, offering simple installation and reliable signal transfer.

Advantages

The rotary dial offers continuous, precise control over the amplifier input level without discrete steps, making it suitable for environments that need fine-tuned volume adjustments. Wall-mount design and compatibility with common 45 x 45 mm faceplates enable straightforward integration into existing electrical and audiovisual infrastructure. The pluggable terminal block and use of CAT5e cabling simplify wiring, maintenance, and replacement while ensuring consistent performance over distance.

Suitable for

• Local volume control for rooms with voltage-controlled amplifiers
• Conference rooms, classrooms, and meeting spaces requiring adjustable sound level
• Fixed installations in offices, retail and hospitality environments
• Systems using centralized amplifiers where wall-mounted control points are needed

Key specifications

• Control type: Rotary potentiometer for continuous volume adjustment
• Control signal: Voltage-controlled input (0–10 V)
• Mounting: Flush wall mount, compatible with 45 x 45 mm installation frames
• Wiring: Twisted-pair CAT5e or better using a pluggable terminal block connector
• Enclosure colour: White

How to use

Install the VC3208 in a standard 45 x 45 mm wall frame and connect the pluggable terminal block to the corresponding control input of the voltage-controlled amplifier using CAT5e (or superior) twisted-pair cable. Ensure correct wiring according to the amplifier's control input documentation and secure the terminal block. Adjust the output level by turning the rotary dial clockwise to increase volume and counterclockwise to decrease it. The unit provides continuous adjustment, so small dial movements result in fine changes to the audio level.

Usage recommendations

For reliable operation, use high-quality CAT5e or better cable and avoid running control cabling in parallel with high-voltage power lines to reduce interference. Verify amplifier compatibility with a 0–10 V control signal before installation. Periodic visual inspection of the wall plate and terminal connections is recommended to ensure secure mounting and consistent control response.
