TOA VM-300IS-EB QJ Loop Monitor and Isolator
The VM-300IS-EB QJ is a short-circuit isolator for controlling a high-voltage loudspeaker network. It is installed in combination with VM-300IM-EB QJ. This isolator comprises a small box with a PCB for mounting on the ceiling speaker‘s top of the Are dome or built-in in the housing of a wall mount speaker. The isolator can also be used as an independent isolator circuit for several speakers as a cost-saving method for installing a loudspeaker network. For solitary use without connection of a loudspeaker, a resistor is to be mounted on the speaker terminal between the common and 6W connection to ensure proper functionality of the isolator. LED for signaling actual function: proper function / short circuit left side / short circuit right side / switch-on.
