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 manufacturer.
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 piece 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 [circle 17] 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 [circle 16] 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 [circle 36] device jack.
Front Door Mic/Camera
1. Connect the line level audio out of a door monitoring device to the Door A/V Audio IN [circle
41] jack for door audio monitoring.
2. Connect the composite video out of the same device or a security camera to the Door A/V
Video IN [circle 42] jack for door video monitoring.
NOTE: These inputs are separate from the Camera video bus used with the AVH21 A/V
Hubs in multiroom applications.
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 [circle 28] . The common source components connected
to the AVR21EN Inputs are all controlled via the Control Out [circle 36] IR outputs. These
