Configuração e instalação
Proper installation is crucial for optimal performance and safety. If you are not comfortable with electrical wiring, please consult a professional installer.
Ferramentas necessárias:
- Chave de fenda (Phillips e Flathead)
- Alicates de decapagem de fios
- Fita isolante (opcional)
- Volumetage Tester (recomendado)
Diagrama de fiação e conexões:
The SVC205 features screw terminals for secure wire connections. Ensure proper polarity (positive to positive, negative to negative) for all connections.

Image: A visual representation of speaker wire (red and black) being connected to the input terminals of the SVC205 volume control. This illustrates the type of wiring accepted by the unit.
- Desligar a energia: 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 os fios: Strip approximately 1/2 inch of insulation from the ends of your speaker wires. The SVC205 accepts up to 14 gauge wiring.
- Conecte os fios de entrada: Conecte os fios dos alto-falantes do seu amplifier or receiver to the "INPUT" terminals on the SVC205. Match the positive (+) and negative (-) terminals for both Left (L) and Right (R) channels.
- Conecte os fios de saída: 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 ampmais vivo.
- Montagem: 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.
- Instale a placa de parede: Attach the matching wall plate over the installed volume control unit.
- Restaurar energia: Once all connections are secure and the unit is mounted, restore power to the circuit.

Instruções de operação
The OSD Audio SVC205 is simple to operate:

Imagem: Frente 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.
- Ligar/desligar: 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.
- Ajuste de volume: 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.
