SETTING SPEAKER LEVELS AT TEST MODE

While at “Speaker Levels” menu, press the AVR 3 remote’s “Test” key

activating the T 747’s Speaker Levels balancing test signal. You will hear

a Test tone. To test each channel, use AVR 3’s [ ] keys to move up or

down the speaker channels. If you do not hear the Test tone, check your

speaker connections or “Speaker Conguration” settings.

To adjust the level of a particular channel, press [ ] to display “^ν” on

the extreme right of the selected channel. Adjust the selected channel to

desired level by pressing [ ] – the level will change by 1 dB increments

up to ±12 dB. After adjusting a channel, press [ ] to eect the change in

level. Press [ ] to select the next channel for adjustment.

You can exit “Test” mode at any time by pressing the [ ] key, bringing you

back to “Speaker Setup” menu.

SPEAKER DISTANCE

Your system’s speaker distance settings are a subtle but important

renement of your setup. Informing the T 747 of the loudspeaker-to-

listener dimensions of each speaker automatically imposes the correct

delays, optimizing imaging, intelligibility and surround-sound ambience.

Enter your dimensions with precision within about 1 foot (30 cm).

SETTING SPEAKER DISTANCE

While at “Speaker Distance” menu, use the [ ] keys to individually

set Front Left, Center, Front Right, Surround Right, Back Right, Back Left,

Surround Left and Subwoofer to the distance measuring from your

principal listening position to the front surface of their corresponding

loudspeakers. Distance can be set up to 30 feet or 9 meters.

Distance can be displayed as feet or meters selectable at the “Unit of

Measure” item.

ADJUSTING THE VOLUME

In addition to the front panel VOLUME knob, use the AVR 3’s [VOL ] to

adjust the volume of the T 747, raising or lowering all the channels together.

A momentary keypress will change the master volume by 1 dB increments.

If you hold down [VOL ] the volume change will “run-on” until the key

is released.

Since recordings vary considerably in overall average level, there is no

imperative to listen at any particular volume setting. A setting of -20 dB

may sound “as loud” from one CD or DVD as -10 dB does from another.

The T 747 will power-up from Standby mode at whatever master volume

setting was last used; however, if the prior setting was greater than –10 dB,

the T 747 will power up at –10 dB. This prevents inadvertently beginning a

session at excessive volume.

MUTING THE SOUND

Use the AVR 3’s “Mute” key to silence all channels completely. Muting is

always available regardless of the source or listening mode selections.
