INSTALLATION
If any source devices are equipped with a compatible Remote IR Input, use
a 1/8-inch mini-plug interconnect cable (not included) to connect the AVR’s
Remote IR Output to the source device’s Remote IR Input.
The AVR 760/AVR 660 outputs a “stripped carrier” IR signal through the
Remote IR Output, but a full-carrier IR signal is available at the Carrier
Remote IR Output. The Carrier Remote IR Output is only available to one
sender at a time, which is assigned in the AVR’s Zone 2 menu. Depending on
whether you select Zone 2, Front or A-BUS, the Carrier Remote IR will only
transmit commands received from the Zone 2 IR Input, the front-panel IR
receiver or the A-BUS system to a device connected to it. This avoids having
conflicting control commands sent to a device from listeners in different areas
of the home.
To control more than one source device through the Remote IR Output,
connect all sources in “daisy chain” fashion, connecting each device’s IR output
to the next device’s IR input, starting with the AVR. Connect devices expecting
a full-carrier IR signal to the Carrier Remote IR Output, and assign the desired
sending zone in the Zone 2 menu. Use the Remote IR Output for devices
expecting a stripped signal.
STEP ELEVEN – Install a Multizone System
The AVR 760/AVR 660 offers several methods of distributing audio to other
areas in your home, and it also features video distribution.
IMPORTANT SAFETY NOTE
: Installing a multizone system typically
requires running cables inside walls. Always comply with the appropriate
safety codes when installing concealed wiring. Failure to do so may present
a safety hazard. If you have any doubt about your ability to work with
electrical and telecommunications wiring, hire a licensed electrician or
custom installer to install the multizone system.
When the system is installed using method B or C below, multizone operation
takes over the Surround Back/ Zone 2 amplifier channels, limiting the system
in the main listening room to 5.2 channels.
Select one or all of these methods for audio distribution:
Connect an external amplifier to the Zone 2 Audio A.
Outputs
. It is recommended that you place the amplifier in the same
room as the AVR 760/AVR 660 so that a shorter length of interconnect
cable is used with a long run of speaker wire to the remote room. A
long run of interconnect cable would be subject to signal degradation.
Depending on your amplifier, distribute the audio signal to a single pair of
speakers, or to several pairs placed in different rooms.
The Zone 2 Audio Outputs offer the benefit of 7.2-channel audio in the
main room simultaneously with multizone operation. However, the
benefit is achieved with the expense of an additional component, i.e., the
amplifier.
Connect the remote room’s speakers directly to the B.
Surround Back/Zone 2 Speaker Outputs
. Reassign the
Surround Back amplifier channels to power the speakers (see Advanced
Functions Manual).
Your main system will be limited to 5.2 channels, affecting playback of
programs recorded in 6.1 or 7.1 channels.
Connect an external amplifier to the Surround Back/Zone C.
2 Preamp Outputs
. This method requires an additional amplifier, but
may increase the total number of remote rooms when used with methods
A and B.
Connect an A-BUS hub or other A-BUS components to the D.
A-BUS port
. Use Category 5/5e cable, as described in the instructions
for your A-BUS components. The A-BUS system carries the audio signal
to the remote components, while receiving IR control codes. A hub
may distribute audio to many remote rooms. To control source devices
exclusively from the remote A-BUS module, connect the AVR’s Carrier
Remote IR Output to a compatible IR input on the source, and assign the
full-carrier output to the A-BUS system in the AVR’s Zone 2 menu. This
avoids having conflicting control commands sent to a source intended for
the A-BUS system.
IR commands received from the A-BUS system are also distributed to the
AVR’s other IR outputs. Visit the Web site at www.harmankardon.com for
information on available Harman Kardon hubs, the ABH 4 and ABH 4000,
and amplified in-wall modules, the AB 1 and AB 2.
Connect a Video Display Device or Switcher (AVR 760 only)
To add video distribution to your multiroom system, connect the Multizone
Video Output either directly to the video display in the remote room or to any
optional video distribution switchers or amplifiers that may be required.
NOTES
:
Only composite video is output to the multizone system. •
S-video, component or HDMI video sources may not be routed through •
the multizone system. Make a second, composite video connection for
the multizone system.
When connecting the • AVR 760 to the remote room’s video display,
distance limitations may exist for composite video connections.
Although the use of low-loss coax cables may reduce signal loss,
optional distribution amplifiers may occasionally be required when long
cable runs are used.
Connect IR Control Devices to the Zone 2 IR Input
For methods A, B and C, connect an IR control device to the Zone 2 IR Input
for remote-room control of the multizone system, source devices and volume
in the remote zone. An A-BUS system does not require a separate IR control
connection.
NOTE
: Only analog audio sources are available to the multizone system.
For digital sources, make a second, analog audio connection. The USB, The
Bridge II and Internet Radio sources are available to the multizone system.
