INSTALLATION
3. Connect an external amplifier to the Surround Back/Multiroom
Preamp Outputs. See Figure 42.
Figure 42 – 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 other options for connecting a multiroom system.
4. Connect an A-BUS hub or other A-BUS components to the A-BUS
Port. See Figure 43.
Figure 43 – A-BUS Port
Use Category 5/5e cable as described in the instructions for your
A-BUS components. The A-BUS system may carry the audio signal
to the remote components, while receiving IR control codes, depend-
ing on the capabilities of your A-BUS components. If you connect
a hub to the AVR 347, you may distribute audio to many remote
rooms. Visit our Web site at www.harmankardon.com for information
on our available hubs, the ABH 4 and ABH 4000, and amplified
in-wall modules, the AB 1 and AB 2.
In addition to the audio signal, you will usually wish to connect an IR
control device to the AVR 347’s Multiroom IR Input so that listeners in
the remote room may turn the multiroom system on or off, select a
source input, control the source device connected to that input and
adjust the volume in the remote zone. As mentioned above, an A-BUS
system does not require a separate IR control connection.
By using external multichannel amplifiers and A-BUS hubs, it’s possible
to construct a system that distributes audio to many rooms throughout
your home.
NOTE: Only analog audio sources are available to the multiroom
system.
Step Eleven – Turn On the AVR 347
Two steps are required the first time you turn on the AVR 347.
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 44. Normally, you may leave the
Master Power Switch in the ON position, even when the receiver is
not being used.
Figure 44 – Power Switches
2. There are several ways in which the AVR 347 may be turned on from
Standby mode.
a) Press the Standby/On Switch on the front panel. See Figure 44.
b) Press the Source Select Button on the front panel. See Figure 45.
Figure 45 – Source Select Button
c) Using the remote, press any one of these buttons: AVR, DVD/CD,
TAPE/The Bridge, HDMI 1/2, VID1, VID2, VID3, VID4, XM, AM/FM
or 6/8CH. See Figure 46.
Figure 46 – AVR and Input Selectors
NOTE: Any time you press one of the Input Selectors on the
remote (i.e., DVD/CD, TAPE/The Bridge, HDMI 1/HDMI 2, VID1,
VID2, VID3 or VID4), the remote will switch modes so that it will
only transmit the codes programmed to operate that device. In
order to control the receiver, press the AVR button to return the
remote to AVR mode.
