press the

Navigation Button o to bring the

CHANNEL ADJUST menu (Figure 13) to

the screen.

When the CHANNEL ADJUST menu first

appears, the test tone is off. Use the

⁄

Navigation

Button o to select any channel for adjustment

using an external source, such as a test disc, from

which to judge the output levels. After the ➔ cursor is

pointing to the channel to be adjusted, press the

‹

›

Navigation Button o to raise or lower the output

level. However, before proceeding with any manual

adjustment we recommend that you first use the AVR’s

internal test tone generator and automatic sequencer

to send a tone to each channel so that you may verify

that all speaker connections have been properly made.

To turn the test tone on and have it automatically

circulate among the channels where a speaker has

previously been configured (see page 26), press

the

⁄

Navigation Button o until the ➔ cursor

is pointing to the TEST TONE SEQ line on

the menu. Next, press the

‹

›

Navigation Button

o until AUTO is shown. Next, press the

Navigation Button o once so that the ➔ cursor

is pointing to TEST TONE. Press the

‹

›

Navigation Button o once to immediately start the

test tone at the Front Left speaker. It will circulate

clockwise around the room, playing for two seconds

in each speaker before switching to the next speaker

position. The ➔ cursor will blink next to the active

speaker to indicate which speaker the sound should

be coming from.

As the test noise circulates, listen to make certain that

the sound comes from the speaker position shown in

the menu listing. If the sound from a

speaker location

does NOT match the position indicated,

turn the

AVR 7300 off using the Main Power Switch

and check the speaker wiring or connections to exter-

nal power amplifiers to make certain that each speaker

is connected to the correct output terminal.

After checking for speaker placement, let the test

noise circulate again, and listen to see which channels

sound louder than the others. Using the front left

speaker as a reference, press the

‹

›

Navigation

Button o to bring all speakers to the same volume

level. When the

‹

›

Navigation Button o is

pushed, the test noise circulation will pause on the

channel being adjusted to give you time to make

the adjustment. When you release the button, the

circulation will resume after five seconds.

Continue to adjust the individual channels until the

volume level sounds the same from each speaker.

Adjustments should be made with the

‹

›

Navigation

Button o only, NOT the main volume controls. If you

are using a sound-pressure level (SPL) meter for pre-

cise level adjustment, set the volume so that the meter

reads 75dB, C-Weighting Slow.

You may also make these same adjustments with

complete manual control over the channel being

adjusted by pressing the

⁄

Navigation Button

o until the ➔ cursor is pointing to the TEST

TONE SEQ line on the menu and then using the

‹

›

Navigation Button o to select MANUAL.

Next, press the

Navigation Button o once so

that the ➔ cursor is pointing to TEST TONE.

Press the

‹

›

Navigation Button o once so that

ON appears and note that the test tone will be heard

from the Front Left speaker.

When the manual

sequencing mode is active, the tone is turned off by

pressing the

⁄

Navigation Button o until the

➔ cursor is pointing to the TEST TONE line and

the

‹

›

Navigation Button o is then pressed to

select OFF in the highlighted video.

The AVR 7300’s EzSet feature may also be used as

an SPL meter to assist in accurate setting of the out-

put levels, when either the internal test tone or an

external source such as a test disc is used. To use

the remote as an SPL meter, follow these steps:

1. Press and hold the SPL Select Button until

the red LED under the Set Button q lights and

the LCD screen in the remote changes to the dis-

play shown in Figure 10.

2. Press the

⁄

Navigation Button o once to

change the bottom line of the remote’s LCD display

to read MANUAL SPL as shown in Figure 14.

Figure 14

3. Press the Set Button q within five seconds to

activate the remote’s manual mode, so that it func-

tions as an SPL meter. The right corner of the bot-

tom line of the remote’s display will show the output

level of the speakers as the test tone circulates. The

level will show as a direct SPL indication between

66dB and 79dB. Below 66dB the remote will

read LOW and above 79dB it will read HIGH.

4. When you are finished with all adjustments, press

the Clear Button

to return the remote to nor-

mal operation.

NOTE: The subwoofer level is not adjustable when the

normal test tone is in use. The subwoofer output level

may also be adjusted when the channel levels are

being trimmed to a program source rather than the

test tone, as shown on page 40.

When all channels have an equal volume level, the

adjustment is complete. To exit this menu, press the

⁄

Navigation Button o until the on-screen

➔ cursor is next to the BACK TO AUDIO

SETUP MENU line; press the Set Button q

to return to the AUDIO SETUP menu.

To adjust the output levels at any time with the test

tone on, using the remote control and semi-OSD

messages, first press the Test Button g. As soon

as the button is pressed, the test tone will begin to cir-

culate as indicated earlier. The correct channel from

which the test noise should be heard will be shown on

the video screen and the Lower Display Line $.

While the test noise is circulating, the proper channel

position will also be indicated in the Speaker/

Channel Input Indicators @ by a blinking letter

within the correct channel.

To adjust the output level, press the

⁄

Navigation Button o until the desired level is

heard. Once the buttons are released, the test noise

will begin to circulate again in five seconds.

When all channels have the same output level, press

the Test Button g again to complete the process.

To trim the channel output levels at any time without

the test tone, using the program material that is cur-

rently playing, first press the Channel Select Button

n. Next, press the

⁄

Navigation Buttons

o to cycle through the available speaker channels

as they appear in the semi-OSD display and in the

Lower Display Line $. When the name of the

channel to be adjusted appears, press the Set Button

q and then use

⁄

Navigation Buttons o

to raise or lower the output level for that channel.

When an individual channel level adjustment is com-

pleted, press the Set Button q again, and use the

⁄

Navigation Buttons o to select another

channel. When all adjustments are done, the unit will

return to normal operation once no button on the

remote control is pressed for five seconds.

NOTE: Output level adjustment is not available for the

VMAx or Surround Off modes.

Tone Control

This menu allows you to configure the tone controls.

Make certain that the AUDIO SETUP menu is

on the screen with the ➔ cursor pointing to the

TONE CONTROL line, and press the Set

Button q. The TONE CONTROL menu

(Figure 15) will appear.
