REAR PANEL DESCRIPTION
Screw Terminals For Speaker Connect (22)
The COM screw terminal is the communal terminal for 4ohm, 8ohm, 16ohm, 70V,100V speakers connecting.
The 4ohm, 8ohm, 16ohm screw terminals should be connected to ordinary sound-box, and can also be used
for monitor output.
The 70V screw terminal is connected to PA-speakers. The maximum voltage is 70V.
The 100V screw terminal is connected to PA-speakers. The maximum voltage is 100V.
The XLR connectors accept microphone inputs. Please use low impedance microphones and properly wired
cables for best results. The TRS connectors on channel 1&2 and RCA connectors on channel 3&4 accept
line-level input, such as: CD/DVD player, mixer, etc..
The MIC1 input with priority-function, automatically
mute other inputs except siren signal, and MIC1 input will be sent to all output channels. If MIC1 input

If siren switch is turned off,
other inputs will return to normal operation.
Pre-amp Outputs (21)
These four outputs send line-level signals to other devices.
DC24V Screw Terminal (23)
This powered mixer can be connected to a DC24V power via the two screw terminals. Then this device can
working without AC power supply.
Removable Power Cord (24)
This receptacle is for the IEC line cord (included) that provides AC power to the device. Connect the line cord to
this connector and to a properly grounded AC supply. Damage to the equipment may occur if an improper line
