INSTALLATION
requirements of all applicable state and local building codes, as
well as NEC (National Electrical Code) requirements. Check with
your local authorities as needed to ensure that all wiring inside
walls is installed in compliance with the proper standards. Failure
to do so may present a potential safety hazard. If you have any
doubt about your ability to work with electrical and telecommuni-
cations wiring, you are advised to hire a professional licensed
electrician or custom installer to install the multiroom system.
1. Connect the remote room’s speakers directly to the Surround
Back/Multiroom Speaker Outputs. See Figure 37.
Figure 37 – Surround Back/Multiroom Speaker Outputs
If you do not require a full 7.1-channel system in your main listening
area, and you prefer not to purchase an external amplifier to power
a pair of remote speakers, you may reassign the AVR 247’s Surround
Back amplifier channels to power the speakers. Your main system will
be limited to 5.1 channels, which affects your ability to enjoy the
many DVDs and other programs recorded in 6.1 and 7.1 channels.
2. Connect an external amplifier to the Surround Back/Multiroom
Preamp Outputs. See Figure 38.
Figure 38 – Surround Back/Multiroom Preamp Outputs
This method may be used when it is more important to distribute audio
to additional rooms than to have a full 7.1-channel system in the main
listening area, as it is still necessary to assign the surround back amplifier
channels to the remote zone, limiting the main system to 5.1 channels.
This method also requires you to provide an additional component, that
is, 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/Multiroom Speaker Outputs.
It is recommended that you place the amplifier in the same room as
the AVR 247 so that a shorter length of interconnect cable is used with
a long run of speaker wire to the remote room, rather than placing the
amplifier in the remote room, which necessitates a long run of intercon-
nect cable that would then be subject to signal degradation. Depending
on the number of channels available in your amplifier, you may distribute
the AVR 247’s analog audio signal to a single pair of speakers for two-
channel listening, to several pairs of speakers located in several different
rooms, or when listening to mono FM radio, to individual speakers
placed in different rooms. Use the Tuning Mode Button to select the
mono mode for FM radio
.
In addition to the audio signal, you will usually wish to connect an IR
control device to the AVR 247’s Multiroom IR Input so that listeners in
the remote room may turn the multiroom system on or off, select a
s
ource 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 multiroom
system.
Step Eleven – Turn On the AVR 247
Two steps are required the first time you turn on the AVR 247.
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 39. 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 247 may be turned on from
Standby mode.
a) Press the Standby/On Switch on the front panel. See Figure 39.
b) Press the Source Select Button on the front panel. See Figure 40.
