and the deepest bass for all other channels will be
routed to the Subwoofer. With OFF selected, the LFE
channel and deepest bass will be equally divided to
all those speakers which have been set to Large.

NOTES:

Speakers set to “Large”, will in addition reproduce

the deepest bass, when Subwoofer is set to ON.

It’s advisable to select Large for the Main speakers

when subwoofer is set to OFF.

SETTING UP THE SURROUND SYSTEM.

To obtain the best results in any of the Surround

Modes it is important that the T 761 is carefully set
up. Performing the complete setup is done using the
On Screen Display menus. It is therefore recom-
mended you connect your Television or monitor to
the T 761 monitor output.

Refer to the chapter “On Screen Display (OSD)” on

how to access the SETUP Menu of the On Screen
Display, choose sub-menus and change settings.

The setup procedure is broken down in three sec-

tions:

1. Speaker Settings

2. Channel Balance

3. Channel Delays

Speaker Settings:

First you need to indicate which speakers are con-

nected to your T 761. Besides the Main speakers
(Left & Right), these can include a Center, two
Surround Speakers and a Subwoofer.

• Call up the SETUP menu of the On Screen

Display (Fig. 7)

• Select the SPEAKER SETTINGS (Fig. 11)

• Highlight PRESET and use 

1

or 

2

cursor button

to select the preset (PRESET 1, 2 or 3) that best
applies to current setting or change the speaker fields
individually as desired.

Four modes available appropriate to the T 761’s

setup: LARGE or SMALL and ON or OFF.

The LARGE mode is used when the speaker is full

range and capable of reproducing the entire audible
frequency spectrum 20Hz to 20kHz. The SMALL
mode is used when the speaker is not capable of
reproducing the deepest bass portion of the audio fre-
quency 20Hz to 100Hz.

The ON mode is used when the speaker is active

and receives the audio information intended. The
OFF mode is used when the speaker is inactive.
Audio signals intended for speakers set to the OFF
position are redirected to the main speakers.

Using a separate center channel speaker will allow

the dialogue to cut through even the biggest sound
effects and musical scores. Having the sound spread
across three front speakers also stabilizes the stereo

image, making the usable listening area much bigger.

For best results, you should consider using a cen-

ter speaker. Ideally it should be the same type as the
left and right speakers.

• Choose SURROUND and select one of the three

modes available: Small, Large, Off.

Installing surround speakers will greatly enhance

the surround experience as these add considerably to
the overall “ambience”.

Dolby Pro Logic encoded material is deliberately

limited in dynamic range and frequency bandwidth for
the surround channel and thus only requires speak-
ers of far lesser specification compared to the front
channels. Dolby Digital however is a full range sys-
tem, with two independent surround channels and
with dynamics equal to that of the front channels. For
this reason it is advisable to choose loudspeakers
which are similar in power handling and performance
capability to those of the front channels. 

For best results, the Surround loudspeakers should

not beam the sound directly at the listener. One way
of achieving this is to use ‘dipole’ Surround speakers
which aim the sound down the walls rather than
directly into the room.

Many film soundtracks rely heavily on very low fre-

quency sound effects which are difficult for normal or
smaller hi-fi speakers to reproduce. To faithfully
reproduce these low frequencies you can use a spe-
cially designed low frequency loudspeaker with its
own built-in amplifier (“active subwoofer”). Because it
is difficult to hear which direction very low frequencies
are coming from, you only normally need one sub-
woofer and this can be placed virtually anywhere in
the room. The Subwoofer output of the T 761 is
designed specifically to drive a subwoofer system.

Dolby Digital uses a dedicated Low Frequency

Effects (LFE) channel. If a subwoofer has been
selected, the LFE channel will be fed to the sub-
woofer output.

Channel Delays:

For the best surround sound performance it is

important that sound from all speakers reach the lis-
tener’s ears at the same time. Because the sur-
round/rear speakers are usually closer to the listener
than the front speakers, there is tendency for the ear
to localise sounds to the rear, because the ear takes
most notice of the sounds that arrive at the head first.
Similarly, the center speaker is often closer to the lis-
tener than the front left and right speakers. To com-
pensate for this, the T 761 can slightly delay the
audio sent to the center and rear (closer) speakers. In
this way, when playing Dolby Digital or Dolby Pro
logic soundtracks, the sound from all speakers
arrives uniformly at the listening position as intended
by the film’s producer.
