INSTALLATION
Select one or all of these systems:
1. Connect an external amplifier to the Zone 2 Audio Outputs.
See Figure 42.
Figure 42 – Zone 2 Audio Outputs
It is recommended that you place the amplifier in the same room
as the AVR 3550HD 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 7.1-channel in the
main room simultaneously with multizone operation. However, the
benefit is achieved with the expense of an additional component,
i.e., the amplifier.
2. Connect the remote room’s speakers directly to the Surround
Back/Zone 2 Speaker Outputs. See Figure 43.
Figure 43 – Surround Back/Zone 2 Speaker Outputs
Reassign the Surround Back amplifier channels to power the speakers
(see page 48). However, your main system will be limited to 5.1 chan-
nels, affecting playback of programs recorded in 6.1 or 7.1 channels.
3. Connect an external amplifier to the Surround Back/Zone 2 Preamp
Outputs. See Figure 44.
Figure 44 – Surround Back/Zone 2 Preamp Outputs
This method requires an additional amplifier, but may increase the
number of remote rooms when used with methods 1 and 2.
4. Connect an A-BUS hub or other A-BUS components to the A-BUS
Port. See Figure 45.
Figure 45 – 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
distrubute audio to many remote rooms.To control source devices
exclusively from the remote A-BUS module, connect the AVR’s A-BUS
IR Output to a compatible IR input on the source.This frees up the
AVR’s other IR outputs for special applications. 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.
For methods 1, 2 and 3, 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.
Step Eleven – Turn On the AVR 3550HD
Two steps are required the first time you turn on the AVR 3550HD.
1. Flip the rear-panel Main Power Switch to the “On” position. The Power
Indicator on the front panel will turn amber, indicating that the AVR
is in Standby mode and is ready to be turned on. See Figure 46.
Normally, you may leave the Main Power Switch on, even when the
receiver is not being used.
Figure 46 – Power Switches
2. There are several ways to turn on the AVR from Standby mode.
a) Press the Standby/On Switch on the front panel. See Figure 46.
b) Using the remote, press the AVR Power On Button or any of the
Source Selectors. See Figure 47.
