INSTALLATION

To control more than one source device using the Remote IR Output,
connect all sources in “daisy chain” fashion, with the AVR’s Remote
IR Output connected to the first device’s Remote IR Input, the second
device’s Remote IR Output connected to the next device’s Remote
IR Input, and so forth.

Step Ten – Install a Multizone System

(Optional)

The AVR 254 offers several methods of distributing music to other
listening areas in your home. A multizone system is not required to enjoy
the home theater experience. If you prefer not to install a multizone
system at this time, skip to Step Eleven to turn on the AVR 254 and
configure it.

IMPORTANT SAFETY NOTE:

Installing a multizone system typi-

cally requires running various cables inside walls. Always comply
with the appropriate safety codes when installing concealed wiring.
The AVR 254’s multizone connections should be installed per the
requirements of all applicable state and local building codes, as
well as NEC (National Electrical Code) requirements. Failure to do
so may present a potential safety hazard. If you have any doubt
about your ability to work with electrical and telecommunications
wiring, you are advised to hire a licensed electrician or custom
installer to install the multizone system.

Multizone operation uses the Surround Back/Zone 2 amplifier channels,
whether you connect the remote speakers directly to the speaker out-
puts, or if you connect an optional external amplifier to the preamp out-
puts. This limits the system in the main listening room to 5.1 channels,
which means you cannot listen to 6.1- or 7.1-channel programs in the
main room.

Select one or both:

1. Connect the remote room’s speakers directly to the Surround

Back/ Zone 2 Speaker Outputs. See Figure 39.

Figure 39 – Surround Back/Zone 2 Speaker Outputs

If you prefer not to purchase an external amplifier to power a pair of
remote speakers, you may reassign the AVR 254’s Surround Back
amplifier channels to power the speakers.

2. Connect an external amplifier to the Surround Back/Multiroom

Preamp Outputs. See Figure 40.

Figure 40 – Surround Back/Multiroom Preamp Outputs

This method requires you to provide an additional component: the
amplifier. However, this method may be used to increase the number
of remote rooms in the system when you are also using the Surround
Back/Zone 2 Speaker Outputs.

Place the amplifier in the same room as the AVR 254 so that a shorter
length of interconnect cable is used with a long run of speaker wire to
the remote room. This is better than placing the amplifier in the remote
room, which necessitates a long run of interconnect cable that would
then be subject to signal degradation.

In addition to the audio signal, you may connect an IR control device to
the AVR 254’s Zone IR Input so that listeners in the remote room may
turn the multizone system on or off, select a source input, control the
source device connected to that input and adjust the volume in the
remote zone.

NOTE:

Only analog audio sources are available to the multizone

system.

Step Eleven – Turn On the AVR 254

Two steps are required the first time you turn on the AVR 254.

1. Gently press the Master Power Switch until the word OFF is no longer

visible. The Power Indicator above the two power switches should
light up in amber, indicating that the AVR is in Standby mode and is
ready to be turned on. See Figure 41. Normally, you may leave the
Master Power Switch in the ON position, even when the receiver is
not being used.

2. There are several ways in which the AVR 254 may be turned on from

Standby mode.

a) Press the Standby/On Switch on the front panel. See Figure 41.

b) Using the remote, press the AVR Power On Button or any of the

Source Selectors. See Figure 42.
