1. AC INLET
Connect the standard three-pin AC cable to this inlet.
2. DC INPUT TERMINALS
When AC power supply and DC 24V are connected at the same time, the AC power will take priority and the
DC power will not be used.
When the AC power is off, the unit will be operated by DC 24V.
When the DC 24V is discharged below 19.2V, the unit will go into Standby mode.
3. SPEAKER OUTPUT TERMINALS
These terminals are for connecting speaker wire. Only connect speakers for which the total sum of the
impedance is equal to or higher than the rated output impedance. Only the 70V terminals (Speaker zones 1-5)
controlled by the speaker selector on the front panel.
Be sure the total sum of speaker output, after factoring in a safety margin, does not exceed 120W for the
P120FACD, and 240W for the P240FACD.
