ence through the use of the delay settings to adjust

the timing for the speaker placement and acoustic

conditions in your listening room or home theater.

The AVR 135’s advanced software enables you to

quickly and easily set delay times without the need to

calculate them using a complex formula. Instead, all

you need to do is measure the approximate distance

between your listening position and each of the

speakers in your system. When you enter those

distances into the AVR’s memory as shown below,

the AVR’s microprocessor does the rest of the work,

calculating the proper delay time. The measurements

need not be accurate to the inch, as the system is

designed to accommodate a typical listening area

rather than require the precise measurement to one

“sweet spot” position.

Due to the differences in the way each surround

mode operates, some modes allow for a greater range

of delay times than others.To avoid problems, we

recommend that delay times be adjusted using the

Dolby Digital mode. If a different mode is selected at

a later time, the AVR 135 will automatically restrict

the delay settings to those required by the surround

mode in use.

Delay times are only adjustable for the Dolby modes,

so you will notice that the

DELAY

menu may not

be accessed when any other mode, such as a DTS

or Logic 7 option, has been selected. In addition,

when a non-Dolby Digital mode such as Dolby 3

Stereo or Pro Logic II is selected, adjustments may

be made to the Surround speakers only.

To set the delay time for a specific input, the

DELAYADJUST

menu (Figure 7) should be

visible on your on-screen display. If it is not, press

the

OSD Button

v

to bring up the

MASTER

MENU

, and press the

until the

to

call up the menu.

NOTE:

In order to adjust the Delay settings for the

surround back channels, a Dolby Digital or DTS source

must be playing. This enables the system to activate

the surround back processing mode.

Once the

menu is on your

screen, note that the default setting to enter the dis-

tances from the speakers to the listening position is in

feet. If your measurements are in feet, proceed to the

next step; if your measurements are made in meters,

press the

Dolby Digital chosen as the surround mode.

Output Level Adjustment

Output level adjustment is a key part of the configura-

tion of any surround sound product. It is particularly

important for a digital receiver such as the AVR 135,

as correct outputs ensure that you hear soundtracks

with the proper directionality and intensity.

IMPORTANT NOTES:

• Listeners are often confused about the operation of

the surround channels. While some assume that

sound should always be coming from each speaker,

most of the time there will be little or no sound in

the surround channels. This is because they are

only used when a movie director or sound mixer

specifically places sound there to create ambience

or a special effect, or to continue action from the

front of the room to the rear. Once the output

levels are properly set, it is normal for surround

speakers to operate only occasionally. Artificially

increasing the volume to the rear speakers may

destroy the illusion of an enveloping sound field

that duplicates the way

you hear sound in a movie

theater or concert hall.

• When the AVR 135 is configured for 6.1-channel

operation using a single surround back speaker, the

output level adjustments will still provide an adjustment

for separate surround back left and surround back right

positions even though your system has only one

surround back speaker. This means that the Surround

Back channel will seem to appear twice, and in 6.1

operation this is normal. The separate SBL/SBR adjust-

ments for 6.1 operation are needed to optimize the

balance between the two discrete channels within the

AVR as they are mixed for output to a single speaker.

Before beginning the output level adjustment process,

make certain that all speaker connections have been

properly made. The system volume should be set to

the level that you will use during a typical listening

session.

Using the Full-OSD System

Follow these steps while seated in the listening posi-

tion that will be used most often:

1. Make certain that all speaker positions have been

properly configured for their “large” or “small” set-

tings (as outlined above) and turn off the OSD

system if it is in use.

2. Adjust the volume so that it is at

-15dB

, as

shown in the on-screen display or

Lower

Display Line

¯

.

3. Output level adjustment is most easily done

through the

CHANNELADJUST

menu

(Figure 8). If you are already at the

MASTER

MENU

, press the

¤

Button

n

until the

on-screen

›

cursor is next to the

CHANNEL

ADJUST

line. If you are not at the

MASTERMENU

, press the

OSD Button

v

to bring up the

MASTERMENU

(Figure 1), and then press the

¤

Button

n

until the on-screen

›

cursor is next to the

line. Press the
