AVR21EN Input/Output Connections
1. Connect the Front, Center, Surround and Surround Back
Speaker Outputs
to their respective speakers, using
quality 14AWG two-conductor stranded speaker wire.
NOTE 1: 16AWG wire may be used for short runs of less than
10 feet. We do not recommend that you use cables with an AWG
equivalent of 18 or higher (smaller gauge), due to the power loss
and degradation in performance that will occur.
NOTE 2: When connecting wires to the speakers, be certain to
observe proper polarity. Note that the positive (+) terminal of each
speaker connection on the AVR now carries a specific color code,
as noted in the
AVR21EN Rear-Panel Features section. However,
most speakers still use a red terminal for the positive connection.
Connect the “negative” (or black) wire to the same terminal on
both the receiver and the speaker.
NOTE 3: While most speaker manufacturers adhere to an industry
convention of using black terminals for negative and red ones for
positive, some may vary from this configuration. To ensure proper
phase and optimal performance, consult the identification plate on
your speaker or the speaker’s manual to verify polarity. If you do
not know the polarity of your speaker, consult the speaker’s manu-
facturer.
To ensure that all the audio signals are carried to your speakers
without loss of clarity or resolution, we suggest that you use high-
quality speaker cable. Many brands of cable are available and the
choice of cable may be influenced by the distance between your
speakers and the receiver, the type of speakers you use, personal
preferences and other factors.
Cables that are run inside walls should have the appropriate
markings to indicate listing with UL, CSA or other appropriate
testing agency standards.
We also recommend that the length of cable used to connect
speaker pairs be identical. For example, use the same length of
cable to connect the front-left and front-right or surround-left
and surround- right speakers, even if the speakers are a different
distance from the AVR21EN.
Subwoofer
Connections to a subwoofer are normally made via a line-level
audio connection from the
Subwoofer Output to the line-level
input of a subwoofer with a built-in amplifier. When a passive
subwoofer is used, the connection first goes to a power amplifier,
which will be connected to one or more subwoofer speakers.
If you are using a powered subwoofer that does not have line-
level input connections, follow the instructions furnished with
the speaker for connection information.
Pre-Out
The AVR21EN provides an 8-channel preamp output section,
Preamp Outputs that can be used with high-powered
amplifiers in the Main Room, if desired. Connect the preamp
output channels to the appropriate amplifier inputs. The Main
Room audio will still be controlled with the AVR21ENR1 remote.
Control Out (Source IR)
Each of the AVR21EN IR emitter outputs is a dedicated output
allowing control of multiple same-brand, same-model components
(multiple DVD/CD players, satellite receivers, etc.).
1. Attach an IR emitter (Audioaccess IREMIT1) to the faceplate of
the device to be controlled.
2. Carefully run the emitter wire back to the AVR21EN rear panel
and connect it to the appropriate
Control Out device jack.
Front Door Mic/Camera Interface (Available Fall 2007)
1. The W.H.E.N. System is designed to integrate with Panasonic
®
door phone and Panasonic-compatible front door stations such
as those from Channel Vision.
2. Connect the audio from the Main Room (home theater) KP21
to the KP A/V audio input.
3. Connect the composite video output from the AVH21 that
corresponds to the Main Room KP21 to the KP A/V video input.
Remote
If the AVR21EN is placed behind a solid or smoked glass cabinet
door, the obstruction may prevent the IR sensor on the AVR from
receiving commands. In this event, an optional remote sensor or
IR repeater system may be used. Connect the IR output of the
remote sensor or IR repeater system to the
Remote In Jack .
The common-source components connected to the AVR21EN
inputs are all controlled via the
Control Out IR outputs. These
components will also be controlled with the IR commands from
the remote sensor or repeater system.
RS-232
The RS-232 port is currently used for factory testing and software
updates. No connection is required.
Multiroom Link
The multiroom link connects the AVR21EN to the AVH21 A/V hubs
in multiroom applications. Connect a Cat. 5e cable terminated with
RJ45 connectors from the
Uplink Terminal on an AVH21 to the
Multiroom Link Terminal on the AVR. These ports can also be
used in smaller systems to add two additional audio zones to the
AVR, by connecting one KP21 keypad directly to each of these
ports. The multiroom link will communicate system control and
distribute digital audio to the individual keypads. See the
Multiroom Installation & Setup/Three Zone System section
for additional information.
