AC Power Inlet –
Connect the supplied AC power cord in here. Only use the supplied power
cord or equivilent 14awg CSA/UL approved power cord.
AC Voltage Selector –
This slide connector changes the AC voltage from 110-120V 60Hz
(North American Standard) to 220-240V 50Hz (European Standard). The unit ships with a
standard North American power cord and the switch set to 110-120V. For use outside North
America use a 14awg AC cord with a European type plug and change the fuse.
110-120V Fuse:T12AL 250V
220-240V Fuse:T6.3AL 250V
DC 24V – 20A –
Emegency backup DC power supplies can be connected to the unit using
the DC input. The DC input is polarity sensitive. Always insure the polarity of the connected
power supply is consistent with the polarity of the unit.
COM/4ohm/25V/70V/100V –
These are the speaker level output terminals. The COM or
common terminal should be connected to the speaker negative -. Choose either
4ohm, 25V, 70V or 100V as the po to connect to your speakers. Note that all the
connected speakers should be coupled to a transformer that corresponds to the
output voltage. Example: 20 speakers which all have 10 watt 70V transformers. Connect the
speakers in parallel. Connect the speaker – negative to the COM terminal and connect the
s positive to the 70V terminal. Never exceed 240/120 watts in combined speakers. We
recommend that installers should maintain 30% headroom of 170/84 watts total.
CAUTION:
Never connect 4ohm, 8ohm or 25V speakers to the 70V or 100V terminals. This
can cause amplifier failure and void your warranty. If you are unsure how to connect this
amplifier to your speakers call or e-mail Factor Electronics for technical support prior to making
any connections.PH: 778-800-1918
