• TRIGGER: On & standby based on trigger signal. When DM7’s Trigger In is connected to another device’s 12V Trigger Out, DM7’s power on/standby can be controlled through this device. DM7 will be powered on when Trigger In detects a 12V signal, and returns to standby state in case the 12V signal disappears.
