SURROUND FUNCTIONS
16. SURROUND MODE
The Surround Mode button scrolls through the T750’s surround
modes: Dolby Pro Logic, Dolby 3 Stereo, Hall and By-Pass
(normal Stereo).
Dolby Pro Logic and Dolby 3 Stereo both decode the surround
sound signals encoded in movie sound tracks from video or TV. To
decode correctly, the video or TV signal must be of a Dolby
Surround or Dolby Stereo soundtrack and coming from a stereo
VCR, TV or satellite/cable receiver.
In the Dolby Pro Logic the rear Surround speakers are also
activated. Use of a centre channel speaker is optional (set with the
Centre button No. 17).
In the Dolby 3 Stereo mode, the rear Surround speakers are
inoperative; the centre channel however is activated in this mode.
Dolby 3 Stereo can be a good alternative to Pro Logic if it isn’t practical
or if space doesn’t allow for the installation of Surround speakers.
For more information refer also to the chapter “Setting up the
Surround System” and appendix “A short guide to Surround Sound”.
In the HALL mode, a realistic level of ambience of surround sound
is added to a normal stereo source such as a CD or FM radio. The
centre channel is inoperative in this mode.
BY-PASS switches to normal Stereo operation.
The selected mode is displayed in the main area of the Display
Panel for 3 seconds and is continuously shown in Surround Mode
area of the Display Panel.
As an additional convenience feature, your T750 memorises
which surround mode you have used with the given input
selection. When you next select that input, your T750 will
automatically choose the same Surround mode again. If you
normally use Dolby Pro Logic mode on the Video 1 and Video 2
inputs, Dolby 3 Stereo mode on the Video 3 input, Hall mode on
FM, and By-Pass (Stereo) on the others, pressing the Input
Selector will automatically default to the right Surround mode
without having to separately press the Surround Mode button.
NOTES: An external source such as a decoder or DVD player with
a decoder built-in (Dolby Digital, DTS* for instance) can be
connected to the 5.1Ch input (No. 5). When the EXT 5.1 CH. input
is selected, no other surround modes are available, so
“SURROUND MODE” extinguishes in the display panel.
17. CENTER
Selects the type of centre speaker used on the main speaker
system. The Center button is only operative with Dolby Pro Logic
or Dolby 3 Stereo selected.
In Dolby Pro Logic mode NORMAL, WIDEBAND, PHANTOM are the
available options. In Dolby 3 Stereo mode NORMAL and WIDEBAND
are available. Select the mode appropriate to the T750’s set-up
The NORMAL mode is used when the centre speaker is smaller than
the front left and right speakers. This mode produces a true centre
image with the very low frequencies (below 70 Hz) filtered out.
The WIDEBAND mode is used when the centre speaker is the same
type as the front left and right speakers. This mode produces a
true centre image with a full frequency range and no low
frequency filtering.
The PHANTOM mode is used when there is no centre speaker
installed. The T750 places the centre information equally on the
left and right front speakers so producing a ‘Phantom’ central
sound image.
The selected Center Mode is displayed for 3 seconds in the main
area of the Display Panel. It is stored in the T750’s memory and
will be automatically recalled each time the unit is switched on.
18. DELAY
Selects the amount of delay applied to the surround speakers
when the T750 is used in DOLBY PRO LOGIC or HALL modes.
Pressing the DELAY button steps the Delay times in 5mS steps from
5mS to 30mS for Hall mode and from 15mS to 30mS for Dolby
Pro Logic mode. Separate delay times can be stored for DOLBY
PRO LOGIC and HALL modes and are held in the T750’s memory.
They are automatically recalled each time the DOLBY PRO LOGIC
or HALL mode is selected.
This function can be altered only when the T750 is in DOLBY PRO
LOGIC or HALL Mode.

for more information.
STORING AM & FM STATIONS
TO STORE A PRESET
• Tune to the radio station you wish to enter into a Preset (refer
to chapter “Front Panel Controls” section 11). If the station is
transmitting RDS information, the RDS indicator will light up
and station initials will be shown in the Display Panel. If a non-
RDS station is found, then just the frequency will be shown.
• To store that station as a Preset, press Memory (No. 14). The
Memory indicator will be displayed and the Preset section will
flash in the Display Panel.
• Press Bank (No. 13) to select which of the three Banks of
Presets (A, B or C) you want to store the station into. Press
either the Tune/Search
or button to select which
Preset number you wish to assign to the station (from 1 to 10),
shown as a flashing number in the Display Panel, and then
press Memory (No. 14) again. The Memory light in the Display
Panel will go out and the station is now stored in your NAD
T750’s memory.
To exit the Memory mode without storing a station, leave all the
tuner controls untouched; the Memory mode will automatically
cancel itself after 8 seconds. The Memory Presets have a memory
back-up, so they will remain stored for several weeks even if the
Receiver is switched off or unplugged from the mains supply.
NOTE:
You can enter a new station into an unused Preset or over-
write an existing programmed Memory Preset. By doing this you
will replace the radio station previously held on that Preset
number.
RECALLING A PRESET STATION
• To select a Preset station, select the Preset mode by pressing the
Preset button (No. 12) until “PRESET” lights up in the display.
• By pressing the Bank button (No. 13) select which Bank of
Presets you want to use (A, B or C, indicated in the display).
• Press either the Tune/Search or buttons (No. 11)
until the right Preset is found and shown in the Display Panel.
NOTE: Any unused Presets will be skipped and it is not possible
to select a Bank unless it has at least one Preset stored into it.
NOTE: The 120V versions (North America) do not have RDS
(Radio Data System).
