Speaker Size Selection

For maximum audio performance, you must tell the A/V

PROCESSOR what speaker configuration you are using.

In the Speaker Size Menu, you will tell the A/V PROCESSOR

whether or not you have a center speaker, side surround

speakers, back surround speakers, and a subwoofer. You will

also tell the unit what size your speakers are, so it knows

whether or not it is safe to route deep bass signals to them.

Generally speaking, a small, bookshelf-type (or smaller)

speaker is considered “small,” and a large, floorstanding

speaker is considered “large.” If you have questions concerning

the proper setting, consult the speaker’s manufacturer.

NOTE: The A/V PROCESSOR does not allow some speaker

combination settings in order to avoid errors. You can set the

subwoofer to “no” only if you have large full-range front speakers.

If you have small limited-bass front speakers, the subwoofer

setting will automatically be “yes.” If your front left and right

speakers are set to “small,” your center speaker will automatically

be set to “small.” If you have no side surround speakers, the

back surround channels will automatically be deactivated.

To Set Speaker Size:

1. From MAIN MENU, press #1 QUICK SETUP–SPEAKER SIZE.

2. To set the size of the front left and right speakers, press the

respective number of the speaker and toggle to small or

large using the SELECT button.

3. Once you have set the front speaker size, press another

number to move on to the other speakers, and or to

adjust the size of those speakers.

4. When you have the size set for all of the speakers, press

EXIT on the remote or front panel to save your settings.

To set the Subwoofer Crossover Points:

1. From MAIN MENU, press #1 QUICK SETUP-SPEAKER SIZE,

then select #s 6-9, one at a time, to adjust crossover values.

2. To set the crossover points, use the SELECT button to

toggle between NONE and 200Hz.

3. When you have the crossover point set for all speakers,

press EXIT on the remote or front panel to save your settings.

To optimize the bass performance and power handling of

your speaker system, you must tell the A/V PROCESSOR what

subwoofer crossover points to use for the front left/right,

center, side surround, and back surround speakers. The A/V

PROCESSOR allows you to set crossover points (ranging from

60 Hz to 200 Hz) for each of these speakers, so that you can

get the best sound fidelity even if your system uses different

types of speakers for front left/right, center, and surround.

Generally speaking, a medium-sized tower speaker works

well with a 40 Hz crossover point. A standard-sized home

theater satellite (or LCR-type) speaker works well with an 80 Hz

crossover point. Slim, on-wall speakers designed to go with

plasma TVs tend to work well with a 100 or 120 Hz crossover

point. Miniature satellite speakers—measuring 4 to 7 inches

high—often demand a crossover point of 150 or 200 Hz.

Speaker Distance

The purpose of delay adjustment is to make all the sounds from

the different speakers in your system arrive at your ears at

the same time. If a sound appears in two speakers at once but

sound from one arrives at your ears earlier (usually because

you are sitting closer to that speaker), it will diminish the

surround effect. The A/V PROCESSOR automatically calculates

the proper delay based on the distance from your listening

chair to each speaker. All you have to do is measure and write

down the distance to each speaker, then enter these numbers

in the A/V PROCESSOR’s Quick Setup Speaker Distance menu.

To Set the Speaker Distance for Each Channel:

1. From the MAIN MENU, press #2 QUICK SETUP–SPEAKER

DISTANCE.

2. Press the respective number of the speaker you wish to

adjust then toggle from one to 30 feet using the SELECT

button on the remote.

3. Go on to adjust the rest of the speakers as you did in #2.

4. When you have the delay set for all of the speakers in your

system, press EXIT and your settings will be saved.
