NOTE: If you’re installing a multizone system, make analog audio
connections for any source devices you want to be able to listen to in Zone 2. only analog
sources are available in Zone 2.

Connect the Radio Antennas
• connect the supplied fm antenna to the Avr’s fm 75Ω antenna connector. for the
best reception, extend the fm antenna as far as possible.
• bend and fold the base of the supplied Am antenna as shown and connect the
antenna wires to the Avr’s Am and gnd connectors. (you can connect either wire to
either connector.) rotate the antenna as necessary to minimize background noise.

Install a Multizone System
IMPORTANT SAFETY NOTE: Installing a multizone system typically requires
running cables inside walls. Always comply with the appropriate safety codes
when installing concealed wiring, particularly all applicable building codes.
Failure to do so may present a safety hazard. If you have any doubt about
your ability to work with electrical wiring, hire a licensed electrician or custom
installer to install the multizone system.
NOTE: only the following analog audio sources are available to Zone 2: the internal radio,
an ipod/iphone device or a uSb memory device inserted in the Avr’s uSb port and up
to two source devices connected to the rear-panel Analog Audio In 1 and 2 connectors.
your Avr offers two different methods of distributing audio to other areas in your home.

each requires different connections:
A. Connect the Zone 2 speakers directly to the Assigned Amp Speaker Output
A. Connect the Zone 2 speakers directly to the Assigned Amp Speaker Output
connectors. Assign the Assigned Amp channels to power the Zone 2 speakers (see
Manual Speaker Setup, on page 36). this method allows you to power a single pair of
speakers for Zone 2.
this method offers the benefit of reduced cost and complexity, but your home theater
this method offers the benefit of reduced cost and complexity, but your home theater
system will be limited to 5.1 channels – the Avr will automatically downmix the playback
of programs recorded in 6.1 or 7.1 channels to 5.1 channels.

B. Connect an external amplifier to the AVR’s Zone 2 Out connectors. this method
offers the benefit of retaining a 7.1-channel home theater in the main room simultaneously
with multizone operation, although it does require an additional amplifier for Zone 2.

we recommend that you place the Zone 2 amplifier in the same room as the Avr so that
you can use a short length of stereo audio cable along with a long run of speaker wire to
the remote room. A long run of stereo audio cable would increase the chance of signal
degradation. depending on your Zone 2 amplifier you can distribute the audio signal to a
single pair of speakers or to several pairs placed in different rooms.

Connect IR Equipment
the Avr is equipped with remote Ir Input and output connectors and a Zone 2 Ir Input
connector that let you remotely control the Avr in a variety of situations:
• when you place the Avr inside a cabinet or facing away from the listener, connect
an external Ir receiver, such as the optional harman kardon he 1000, to the Avr’s
Ir In jack.

• If any source devices are equipped with a compatible Ir input, use a 1/8-inch
(3.5mm) mini-plug interconnect cable (not included) to connect the Avr’s Ir out jack
to the source device’s Ir input.

Making Connections,
to control more than one source device through the Avr’s Ir remote out connector,
connect all sources in “daisy chain” fashion, connecting each device’s Ir output to the
next device’s Ir input, starting with the Avr.
• If you install a multizone system, connect an Ir control device to the Zone 2 Ir In
connector for remote-room control of the multizone system, source devices and
volume in the remote zone.

If a source device is shared with the main listening area, any control commands issued
to that source will also affect the main room.
Connect the Trigger Output
If your system has equipment that can be controlled by a dc trigger signal, connect it to
the Avr’s trigger out connector with a mono 1/8-inch (3.5mm) mini-plug interconnect
cable. the Avr will supply a 12v dc (100mA) trigger signal at this connection whenever
it is powered on.
