Installation And Configuration; Power Control Connection - Harman Kardon PA 2000 Owner's Manual

Installation and Configuration

SAFETY NOTE: When making connections
between any source components such
as AV receivers, surround processors or
multiroom controllers and the PA 2000, or
when making any connections to speakers,
be certain that both the source device and
the PA 2000 are turned off. To ensure that
there will be no unwanted signal tran-
sients that can damage equipment or
speakers, it is always best to unplug all
equipment before making any connections.
Modern electronic products often have a
"standby" mode that may be activated
even though the product may appear to be
turned off.
Power Control Connections
The PA 2000 features a built-in remote turn-on
system that will automatically turn on either or
both of the amplifier pairs in one of three ways.
Depending on your specific application, the unit
may be turned on manually using the Power
Switch 1, or via automatic sensing of either
an input source or a low-voltage trigger signal.
For manual operation, no special installation is
required. For automatic turn-on, follow the
instructions below for the chosen trigger
method.
Note that when the unit is operated in the stan-
dard, two-pair output mode, each of the channel
pairs may be operated by the same trigger
method, or they may be turned on via different
methods.
Remote Turn-On From an External Device
Using the Low-Voltage Trigger
To configure the PA 2000 so that either or both
of the channel pairs turn on automatically in
response to a low-voltage trigger signal, follow
these steps:
1. Place the Power Control Mode Switch
£ for either channel in the center position,
so that the switch is over the words "AC/DC
TRIGGER".
2a. To trigger the amplifier from a device such as
a preamp surround processor or multiroom
controller with a built-in trigger jack, connect
one end of a cable with a 3.5mm mono
mini-plug to the Trigger Jack § on the
PA 2000. Connect the other end to a match-
ing jack on the device that will provide a
3-volt to 30-volt signal (AC or DC with the
tip of the plug "positive" +) when the unit is
to be turned on.
or
2b. To trigger the amplifier using the switched
AC accessory outlet on an AV receiver or
other source device, purchase a small AC to
DC power converter, as is typically used to
replace the batteries in portable electronics
devices. Select a model that is capable of
delivering 3 to 30 volts AC or DC, and make
certain that one of the "tips" provided with
the unit is a 3.5mm mini-plug (DC with the
tip of the plug "positive" +). Plug the trans-
former end of the converter into the
switched AC output on the source product,
and connect the 3.5mm mini-plug to the
Trigger Jack §.
3. Press the Power Switch 1 in so that it is
engaged, and note that the Standby
Indicator 3 will light for the channel pairs
selected for trigger control operation.
When the control unit connected to the Trigger
Jack is turned on and sending a trigger signal, any
PA 2000 amplifier pair whose Power Control
Mode Switch £ is in the AC/DC TRIGGER
position will automatically turn on. When the
source unit is turned off and no longer sending a
trigger signal, any amplifier pair whose Power
Control Mode Switch £ is in the AC/DC
TRIGGER position will enter Standby.
NOTE: When the PA 2000 is used in the Bridged
mode as a single-pair stereo amplifier, use the
Power Control Mode Switch £ in the area
labeled "BRIDGE/CHANNEL ONE" to make the
settings for the desired turn-on mode.
Remote Turn-On Using Music Sense
To configure the PA 2000 so that either or both
of the channel pairs turn on automatically when
the amplifier is receiving an audio signal, follow
these steps:
• Connect the audio input as normal to the
audio Input Jacks ¡.
• For each channel pair that you wish to control
using an incoming audio signal, slide the
Power Control Mode Switch £ to the far
left so that the switch is under the words
"MUSIC SENSE".
• Press the Power Switch 1 in so that it is
engaged, and note that the Standby
Indicator 3 will light for the channel pairs
selected for Music Sense control operation.
In this configuration, the amplifier for any chan-
nel pair selected for Music Sense control opera-
tion will automatically turn on whenever it is
receiving an audio input signal and will return to
the Standby mode 10 to 15 minutes after the
audio signal stops.
NOTE: When the PA 2000 is used in the Bridged
mode as a single-pair stereo amplifier, use the
Power Control Mode Switch £ in the area
labeled "BRIDGE/CHANNEL ONE" to make the
settings for the desired turn-on mode.
