Volume/Output Level Controls:
Press
these controls to change the volume level up or
down for an individual channel pair in remote
room applications. For surround sound applica-
tions, use them with the test tone in your
receiver or processor to set the output levels.
See page 13 for more information.
™
Channel 3 Speaker Terminals:
Connect
these terminals to the speaker pair that is fed by
the Channel 3 amplifier section.
£
Channel 4 Speaker Terminals:
Connect
these terminals to the speaker pair that is fed by
the Channel 4 amplifier section.
¢
Channel 1 Speaker Terminals:
Connect
these terminals to the speaker pair that is fed by
the Channel 1 amplifier section.
∞
Channel 2 Speaker Terminals:
Connect
these terminals to the speaker pair that is fed by
the Channel 2 amplifier section.
NOTE:
When the amplifier is operated in the
Bridged configuration, connect the speakers as
shown on page 9 or 10.
§
IR Remote Control Output:
Connect this
jack to the IR Input jack on another piece of
equipment if you wish to use the incoming IR
remote signals to control other source or control
products. See page 12 for more information.
¶
MR On/Off Command Switch:
When the
PA 4000 is used in conjunction with a compati-
ble Harman Kardon AVR with multiroom capa-
bilities (such as the AVR 7000, AVR 510 or
AVR 310), place this switch in the ON position if
you wish to control both the PA 4000 and the
AVR via a remote keypad or IR sensor. When
used with any other product, the switch position
is not applicable.
•
Fuses:
If any of the front-panel
Indicators
234
do not light and no sound is heard
when a signal is applied, the cause may be a
blown fuse.
IMPORTANT SAFETY NOTE:
Fuses should only be removed or changed
with the power cord removed from the
unit.
ª
AC Power Cord Jack:
Connect the AC
power cord supplied with the unit to this jack,
and connect the power cord plug to an AC
outlet.
‚
Main Amp Output Jacks:
These jacks carry
through the input signal connected to the
Main
Amp Input Jacks
⁄
. If you wish to continue
the input feed to additional amplifiers, connect
these jacks to the input jacks of the next amplifier
to be used.
⁄
Main Amp Input Jacks:
The signal con-
nected to these input jacks will be sent to all
amplifier channels when the
Channel 3
Separate Switch
¤
is in the OFF position.
When the switch is in the ON position it will feed
the Channel 1 and Channel 2 amplifier channels
at all times, and the Channel 4 amplifier when
the
Bridge 2 Amplifier Mode Switch
°
is in
the Normal position. See pages 9–10 for more
information.
¤
Channel 3 Separate Switch:
This switch
determines the input to the Channel 3 amplifier.
When the same input signal is used to feed all
four amplifier pairs, place the switch in the OFF
position. When a separate feed is used for the
Channel 3 amplifier so that the PA 4000 carries
two separate signals, place the switch in the ON
position. See page 10 for more information.
