1. AC INLET
Connect the standard three-pin AC cable to this inlet.
2. DC INPUT TERMINALS
These terminals are provided for the connection of a battery.
Connect a 24VDC battery to these terminals.
Make sure the red terminal is connected to the battery’s positive (+) terminal, and the black terminal to the
battery’s negative (-) terminal.
When AC power supply and DC 24V are connected at the same time, the unit is worked by AC power supply.
When the AC power is off, then the unit is worked by DC 24V.
When the DC 24V is discharged below 19.2V, then the unit is entered in to the STAND-BY mode.
3. SPEAKER OUTPUT TERMINALS
These terminals are for speaker wire connections. Connect speakers which total sum of the impedance is
equal to or higher than the rated output impedance. Only high impedance terminals(speaker zone 1-5) can
be controlled by the speaker selector on the front panel.
Be sure, the total sum of output is 120W for PCT-610 and 240W for PCT-620.
4. RS-232C CONTROL
The unit can be controlled by AMX or CRESTRON System with this RS-232C interface.
The maximum cable length is about 15m.
