Setup and Installation
Proper installation is crucial for optimal performance and safety. If you are not comfortable with electrical wiring, please consult a professional installer.
Tools Required:
- Screwdriver (Phillips and Flathead)
- Wire Strippers
- Electrical Tape (optional)
- Voltage Tester (recommended)
Wiring Diagram and Connections:
The SVC205 features screw terminals for secure wire connections. Ensure proper polarity (positive to positive, negative to negative) for all connections.

- Turn Off Power: Before beginning any wiring, ensure that the power to the audio system and the circuit where you are installing the volume control is completely turned off at the main breaker.
- Prepare Wires: Strip approximately 1/2 inch of insulation from the ends of your speaker wires. The SVC205 accepts up to 14 gauge wiring.
- Connect Input Wires: Connect the speaker wires from your amplifier or receiver to the "INPUT" terminals on the SVC205. Match the positive (+) and negative (-) terminals for both Left (L) and Right (R) channels.
- Connect Output Wires: Connect the speaker wires leading to your speakers to the "OUTPUT" terminals on the SVC205. Again, ensure correct polarity for Left (L) and Right (R) channels.
- Adjust Impedance Jumpers (if applicable): The SVC205 includes front-mounted adjustable jumpers for impedance matching. Refer to the diagram below for typical settings. Adjust these jumpers based on the total impedance of your connected speakers to prevent overheating and damage to your amplifier.
- Mounting: Carefully push the wired SVC205 unit into a standard single gang electrical box. The unit requires a minimum depth of 2.9 inches. Secure the unit to the electrical box using the provided mounting screws.
- Install Wall Plate: Attach the matching wall plate over the installed volume control unit.
- Restore Power: Once all connections are secure and the unit is mounted, restore power to the circuit.

Operating Instructions
The OSD Audio SVC205 is simple to operate:
Image: Front view of the OSD Audio SVC205 In-Wall Volume Control, showing the prominent rotary volume knob and the smaller on/off toggle switch located below it.
- Power On/Off: Use the small toggle switch located below the rotary knob to turn the audio on or off. Flipping the switch will completely mute or unmute the sound.
- Volume Adjustment: Rotate the large knob clockwise to increase the volume and counter-clockwise to decrease it. The 12-step linear design provides precise control over the audio level.
