Dummy Load Capacitor

The VA-DLC dummy load capacitor is used for the speaker line surveillance based on impedance measurement. When a number of speakers are installed with long wires, the VA-DLC can provide a reliable monitoring method to detect the open circuit of entire speaker line even the last speaker.

The VA-DLC has a 4-step DIP switch, and each step refers to individual speaker line power load. To know which step to switch, utilizes the Setup Wizard on the LCD front panel of BTQ-VM4/VM8 controller or BOUTIQUE web browser, and it will automatically calculate the speaker line power load.
