Features:

-Standard chassis design, 2U aluminum alloy brushed panel; user-friendly drawing design, beautiful and practical;

-12-way independent partition selection switch, the partitions can be switched at will without interfering with each other;

-Equipped with 4 audio inputs, the working status of the partition is indicated by indicator lights;

-With 4 audio inputs, 2 of which are background music programs and 2 are emergency priority programs;

-There are two kinds of short circuit control signal input, one is to trigger the whole area, and the other is the whole area short circuit signal output;

-The device adopts double relays and double-cut control circuit at the same time, and the isolation of the channel is ≥80dB, which solves the problem of crosstalk between channels.
