19. IEC POWER INPUT CONNECTOR: This
is where you connect the supplied AC
power cord.
Before plugging in the power
cord, make sure that the Voltage
Selector Switch [20] is set to the same
voltage as your local AC mains.
20. VOLTAGE SELECTOR SWITCH:
Make sure the switch is in the
correct position for your local AC
mains voltage before you plug in the AC
power cord. Use a small at screwdriver
to slide the switch if required.
21. POWER SWITCH: Use this switch to
turn the overall system power on or o.
Press the switch to the left to turn on
the power. Press the switch to the right
to put the amp into Standby mode�
(In Standby mode, the amp will not
function, but the circuits are still live.) To
remove AC power, either turn o the AC
mains supply, or unplug the power cord
from the amplier and the AC mains
supply�
22. VENTILATION: Make sure that the
ventilation openings are not obscured
in any way. This will allow the ow of air
to cool the power amplier’s heatsinks.
See “Fault/Thermal Considerations” on
page 16 for more information�
23. SPEAKER OUTPUTS: These individual
Speakon and 1/4" TS Output jacks
connect to your speaker cabinet(s).
The rated power output of the PF-500
is 300 Watts RMS into 8 Ω, or 500
Watts RMS into 4 Ω. The rated power
output of the PF-800 is 400 Watts RMS
into 8 Ω, or 800 Watts RMS into 4 Ω.
The two Speaker Outputs are
wired in parallel, and you can
use either one or both. Make sure the
total speaker impedance load is 4 Ω or
greater. For example, you could
connect:
• Two 16 Ω speakers (an 8 Ω load),
• Two 8 Ω speakers (a 4 Ω load)
• One 4 Ω speaker
Use (non-shielded) speaker
cables with Speakon or 1/4" TS
ends to make the connections. Do not
use (shielded) instrument cables as
they may overheat.
24. XLR LINE OUT JACK: Typically, you
would connect this balanced output
to the balanced input of an external
mixer or a recorder. In this way, you do
not need to mic the speaker cabinet
in order to add it to the main mix or to
record. This XLR Output is not aected
by the Volume control [15].
This output can connect to external
power ampliers, or powered
loudspeakers, as long as they include
their own input controls to adjust the
volume level.
Balanced connections allow long
cable runs to be used, as hum and
noise pickup in the line is minimized.
