18 INSTALLATION AND CONNECTIONS
Multiroom Audio Connections
Depending on the distance from the AVR 4000
to the remote room, two options (A and B) are
available for audio connection:
Option 1: Use high-quality, shielded stereo
audio interconnect cable with phono plugs on
both ends from the AVR 4000’s location to the
remote room. At the remote room, connect the
interconnect cable to a stereo power amplifier.
The amplifier will be connected to the room’s
speakers. No volume control is required, as the
AVR 4000 and the remote IR link will provide
that function. At the AVR 4000, plug the audio
interconnect cables into the Multi-Room
Output jacks
9
on the AVR 4000’s rear panel.
Option 2: Place the amplifier that will provide
power to the remote location speakers in the
same room as the AVR 4000, and connect the
Multiroom Output jacks
9
on the rear panel
of the AVR to the audio input of the remote
room amplifier. Use the appropriate speaker wire
to connect the optional power amplifier to the
remote speakers. High-quality wire of at least
2.5 mm
2
is recommended for long multiroom
connections.
IMPORTANT NOTE: Any cables run inside walls
should carry any certification that is required by
the local building and electrical codes.To avoid
interference, audio and speaker cables should not
be parallel to, or run in the same conduits or path
with,AC cables. If you have any questions about
multiroom wiring, consult your dealer, custom
installer or low-voltage electrical contractor.
External Audio Power Amplifier
Connections
If desired, the AVR 4000 may be connected to
optional, external audio power amplifiers.
When an external amplifier is used, connect the
Preamp Out jacks
A
to the inputs on the
amplifier. Note that when external amplifiers or
devices are used, the volume control is still con-
trolled by the AVR, although additional volume
controls on the external device may impact the
volume settings and output levels from the AVR.
External Audio Decoder Connection
To provide for ultimate flexibility, the AVR 4000
may be used in conjunction with optional, exter-
nal decoders for digital audio systems other than
the AVR 4000’s own built-in Dolby Digital and
DTS decoding system or with DVD players hav-
ing those decoders integrated. If an external
decoder is used, connect the output jacks of the
decoder to the 6-Channel Direct inputs
8
,
making sure to match channels.
These jacks may also be used for connections to
devices such as DVD players or High Definition
Television (HDTV) sets or decoders that feature
built-in digital surround decoders. Although the
digital decoding system in the AVR 4000 will typi-
cally provide audio performance that is superior to
other decoders, you may use these jacks to provide
an additional 6-channel input for connection to a
DVD player or HDTV set with a built-in decoder
and discrete 6-channel analog outputs.
AC Power Connections
This unit is equipped with two accessory AC out-
lets. They may be used to power accessory
devices, but they should not be used with high-
current draw equipment such as power ampli-
fiers. The total power draw to the Unswitched
Outlet
G
must not exceed 100 watts, that to
the Switched Outlet
F
50 watts.
The Switched
F
outlet will receive power only
when the unit is on completely. This is recom-
mended for devices that have no power switch
or a mechanical power switch that may be left in
the “ON” position.
NOTE: Many audio and video products go into a
Standby mode when they are used with
switched outlets, and cannot be fully turned on
using the outlet alone without a remote control
command.
The Unswitched
G
outlet will receive power
as long as the unit is plugged into a powered AC
outlet and the Main Power Switch
1
is on.
Finally, when all connections are complete, plug
the power cord into a nonswitched 220-240-volt
AC wall outlet.You’re almost ready to enjoy the
AVR 4000!
