Adjust Speaker Distance Menu

As explained above in Step Two – Measure

Speaker Distances, sometimes the speakers are

placed at different distances from the listening-

position, which can muddy the sound, as sounds

are heard earlier or later than desired.

Even if all of your speakers are placed the same

distance from the listening position, do not skip

his menu.

On the Manual Speaker Setup menu, move the

cursor to the Distance line and press the OK

Button to display the Adjust Speaker Distance

menu. See Figure 12.

Figure 12 – Adjust Speaker Distance Menu

This menu requires you to enter the distance

from each speaker to the listening position,

which you measured in Step Two – Measure

Speaker Distances and noted in Table A3 in the

appendix.

The default unit of measurement is feet. If you

wish to change the unit to meters, press the

Back/Exit Button until you return to the main

AVR menu. Scroll down to the System line, and

select it to view the System Settings menu. Scroll

down this menu to the General AVR Settings

section, and select the Unit of Measure line.

Press the OK Button to change the setting from

Feet to Meters.

Use the K/L Buttons to move the cursor to

the Front Left line, press the OK Button then use

the M/N Buttons to change the measurement

as needed. The values vary between 0 and 9

meters, with a default of 3 meters for all speak-

ers. Use the M/N Buttons to move to each

speaker in turn – Center, Front Right, Surround

Right, Surround Back Right, Surround Back Left,

Surround Left and Subwoofer, if present in your

system.

NOTE: When the multiroom system is in use, the

surround back channels are automatically

assigned to the multiroom system, as mentioned

earlier. You will not be able to adjust the delay

settings for these channels, and the cursor will

skip past them.

Step Four – Setting Channel Output Levels

Manually

For a conventional 2-channel receiver, the bal-

ance control enables the user to control the

stereo imaging by adjusting the relative loud-

ness of the left and right channels, as heard at

the listening position.

With up to seven main channels plus a sub-

woofer, imaging becomes both more critical and

more complex. Unlike the rotary balance control,

the goal of the AVR 355/AVR 255’s channel out-

put adjustment process is to examine the output

level of each channel independently and ensure

that each is heard at the listening position with

equal loudness.

If you followed the instructions in the Initial

Setup section, then you let EzSet/EQ handle this

critical task for you, simply and automatically.

However, if you prefer to make these adjust-

ments manually, the AVR 355/AVR 255’s Adjust

Speaker Levels menu allows you to do so, either

using the system’s test tone or while playing

source material. In addition, this is the only

method for adjusting the level of the subwoofer.

You may use a handheld SPL meter (available at

most electronics stores) set to the C-Weighting,

Slow scale.

1. Make sure all speakers have been connected

correctly.

2. Adjust the number of speakers, crossover dis-

tance and submode for each speaker in your

system as described in Step Three.

. If you are using a handheld SPL meter with

source material, such as a test disc or another

audio selection, play it now and adjust the

VR’s master volume control until the meter

measures 75dB.

4. There are several methods of adjusting the

channel output levels, using either the test

tone or source materials. In all cases, you may

measure the channel levels in one of two

ways:

a) By ear. Try to adjust the levels so that all

channels sound equally loud.

b) Using a handheld SPL meter set to the C-

Weighting, Slow scale.Try to adjust each

channel so that the meter reads 75dB.

The best method of setting the output levels is

by running EzSet/EQ, as described in the Initial

Setup section. If any finer adjustments are

desired, we recommend using the menu system

to make the adjustments while playing the AVR’s

built-in test tone and measuring the output

using an SPL meter. Less effective would be to

measure the output by ear. Press the AVR Button

to display the menu system, and then navigate

to the Speaker Setup line. Press the OK Button

to display the Speaker Setup menu. Select

Manual Speaker Setup, press the OK Button, and

then navigate to the Level Adjust line. Press the

OK Button to display the Adjust Speaker Levels

menu. See Figure 13.

All of the speaker channels will appear with

their current level settings.
