components will also be controlled with the IR commands from the remote sensor or repeater
system.
RS-232
The RS232 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 CAT5e cable terminated with RJ45 connectors from the
Uplink Terminal [pentagon
16]
on an AVH21 to the
Multiroom Link Terminal [circle 30]
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:
Multiroom Installation & Setup/Three
Zone System
for additional information.
AVR21EN CONFIGURATION
Theater Setup
When all audio, video and system connections have been made, there are a few configuration
adjustments that must be made. A few minutes spent to correctly configure and calibrate the unit
will greatly add to your listening experience.
Speaker Selection and Placement
The placement of speakers in a multichannel home theater system can have a noticeable impact
on the quality of sound reproduced. No matter which type or brand of speakers is used, the same
model or brand of speaker should be used for the left front, center and right front speakers. This
creates a seamless front soundstage and eliminates the possibility of distracting sonic
disturbances that occur when a sound moves across mismatched front-channel speakers.
Speaker Placement
Depending on the type of center channel speaker in use and your viewing device, place the
center speaker either directly above or below your TV, or in the center behind a perforated front-
projection screen.
Once the center channel speaker is installed, position the front left and front right speakers so
that they are as far away from one another as the center channel speaker is from the preferred
listening position. Ideally, the front channel speakers should be placed so that their tweeters are
no more than 24" above or below the tweeter in the center channel speaker.
Depending on the specifics of your room acoustics and the type of speakers in use, you may find
that imaging is improved by moving the left front and right front speakers slightly forward of the
center channel speaker. If possible, adjust all front loudspeakers so that they are aimed at ear
height when you are seated in the listening position.
Using these guidelines, you’ll find that it takes some experimentation to find the correct location
for the front speakers in your particular installation. Don’t be afraid to move things around until the
system sounds correct. Optimize your speakers so that audio transitions across the front of the
room sound smooth, and that sounds from all speakers appear to arrive at the listening position
at the same time (without delay from the center speaker compared to the left and right speakers).
