CONNECTING LOUDSPEAKERS
There are many different ways of connecting
loudspeakers to your SA750 amplifier. The
following section describes how to connect the
speakers and amplifier for the most common
configurations.
Single Wiring
If each speaker has more than one pair of
connecting terminals, use the terminals labelled
" " or "Low Frequency" on your speakers.
Connect the red positive terminal of the right
speaker connection on the amplifier (labelled )
to the positive terminal of your right speaker.
Similarly, connect the black negative terminal
of the right speaker connection on the amplifier
(labelled ) to the negative terminal of your
speaker. Repeat the process for the left speaker,
using the terminals labelled and on the
amplifier.
WARNING: If your speakers support bi-
wiring, there will be a strip of conductive
metal connecting the low-frequency (LF)
terminals to the high-frequency (HF)
terminals; this MUST NOT BE REMOVED in
a single-wired system.
Notes On Making Speaker Connections
Do not make any connections to any amplifier while it is switched on. We recommend that your
amplifier is completely disconnected from the mains supply before starting.
Before switching your amplifier on for the first time after connecting to speakers, please check
all connections thoroughly. Ensure that bare wires or cables are not touching each other or the
amplifier’s chassis (which could cause short circuits), and that you have connected positive (+)
to positive and negative (–) to negative. Be sure to check the wiring for both the amplifier and the
speaker.
After making connections: switch the amplifier on, select a source signal, then gradually increase
the volume to the required listening level.
If you are unsure as to how your system should be connected, please contact your JBL dealer
who will be happy to help you.

CONNECTING LOUDSPEAKERS CONTINUED
Bi-Amping
Bi-amping is the separation of the amplification
of low and high-frequency signals over two
amplifiers.
Bi-amping requires the use of two amplifiers per
channel. Normally, your SA750 is used to drive
the high frequency (treble) speakers, while a
second amplifier (such as the JBL SDA2220) is
used for the lower (bass) frequencies.
Connect the SA750 to the speakers as described
for single wiring, with the exception that the
SA750 should be connected to the speaker
terminals labelled "HF" or "High Frequency".
Next, connect the SDA-2220 power amplifier
to the "LF" or "LOW Frequency" terminals,
as shown in the diagram. A pair of audio
interconnect cables are also required to connect
the pre-amp outputs of the SA750 to the power
amplifier inputs of the second amplifier.
WARNING: The strip of metal on the
speakers connecting the low frequency
(LF) terminals to the high frequency (HF)
terminals MUST BE REMOVED. Failure to do
so will result in damage to both amplifiers,
which will not normally be covered under
warranty.

LISTENING
Listening Using Headphones
The headphone socket (PHONES) accepts
phones with an impedance rating between 16Ω
and 2kΩ, fitted with a 3.5mm stereo jack.
By default the pre-amp outputs and speakers are
muted when the headphones are plugged in.
The speakers and pre-amp outputs can be
configured to remain active when headphones
are connected using the Headphone Override
function in the setup menu. See "Phones Ovr" on
page EN-17 for more information.
The headphone output is always active, unless
the amplifier has been muted.
Balance Control
Use the balance control on the front panel to
move the sound stage from left to right.
Direct Mode
The SA750 allows the option to bypass certain
elements of the audio processing to allow for a
purer listening experience.
Analog Direct
In order to apply Dirac Live room correction the
SA750 converts all analog inputs to a digital signal
using a high quality Analog to Digital Convertor
(ADC). Once the signal has been processed by
the on board Digital Signal Processor (DSP) it is
converted back to an analog signal using a high
quality Digital to Analog Convertor (DAC).
The DIRECT function bypasses the ADC, DSP
and DAC to allow the analog signal to be sent
directly to the preamp stage for the purest signal
path.
An icon on the display indicates if the direct path
is enabled for the current analog input.
Analog direct is enabled. ADC, DSP and
DAC are bypassed.
When Analog Direct is enabled DIRAC room
correction cannot be applied.
Processor Mode
Processor mode can be assigned to most Analog
inputs. In this mode, the volume is set to a fixed
level.
This mode allows the use of the SA750 to be
used in conjunction with a AV receiver in a
combined home cinema and two channel listening
environment.
Please refer to "PM Input" on page EN-17 for
details on how to specify which input is to be used
in processor mode. For setting the desired fixed
volume level, please refer to "PM Input" on page
EN-17.
Pre-Amplifier Output
To use the SA750 as dedicated pre-amplifier, or
as part of a bi-amped system, connect the
sockets to the input sockets of your power
amplifier.
See "Bi-Amping" on page EN-11 for details of
a suggested system using an external power
amplifier.

DIRAC LIVE
There is a proprietary automatic loudspeaker
setup function built into your SA750 from Dirac
Research. Using a PC/Mac based application,
this attempts to set all the essential speaker
settings for all the speakers in your system. It also
calculates room equalisation (Room EQ) filter
values to remove some of the worst effects of
resonant frequencies in the listening room.
Your SA750 is supplied with a calibration
microphone, which should be inserted into a USB
socket on a PC or Mac connected to the same
network as the SA750 and positioned as directed
by the Dirac Live for JBL PC/Mac application.
This microphone picks up the special calibration
tones generated by the speakers when Dirac
Live for JBL application is run. The SA750 then
analyses the signal and will correct any resonant
frequencies in the room which need control by
filtering.
To help the system be as accurate as possible
when performing Dirac Live for JBL setup, there
are a few guidance rules that should be followed:
Minimise any background sounds in the
listening room and other nearby rooms.
Close all windows and doors in the listening
room.
Turn off all fans including air-conditioning
systems.
Mount the microphone on a tripod or similar.
Position the set up microphone pointing
upwards at roughly head height in the normal
listening position. It is not necessary to point the
microphone directly at the speaker generating
the test tone. (It helps if you are able to position
the microphone exactly where your head would
normally be for listening, with the microphone in
direct unobstructed view of all speakers.)
When activated, a calibration tone is played
through each channel of the SA750. The
calibration tone cycles round each of the speakers
multiple times as the different parameters are
calculated.
Note: By default, Room EQ is not applied to any of the
source inputs.
You should enable Room EQ on inputs you think
benefit from this feature, as required, by listening
when playing typical source material through each
input. After being calculated, this is enabled from
within the setup menu or by the front panel or
remote control button.
While room equalisation can help to reduce
problems with listening room acoustics, it is
usually far better to try to solve these problems
with the room directly. Proper loudspeaker
positioning, acoustic wall treatments and moving
the listening position away from walls should
produce far better results overall. However it may
be difficult to do this in a home environment, so
Room EQ is your next best choice.
Problems
The Auto Speaker Setup function is normally very
accurate but occasionally false results can be
generated. Problems may be as a result of:
external sounds or rumbling/handling noises
picked up by the microphone
sound reflections off hard surfaces (e.g.
windows or walls) close to the listening position,
very strong acoustic resonances within the
room,
obstacles (such as a sofa) between speakers
and the microphone.
If you are still experiencing difficulties or you wish
to have the most accurate results for ultimate
surround performance, we recommend using the
manual method of establishing speaker distances
and levels.

Using Dirac
You can store up to three Dirac EQ curves in the
SA750. Each input can use a different curve, for
example a “Movie” curve on the BD input and
“Music” curve on the CD input.
This can be set on a per input basis using the
key on the front panel or key on
the remote.
Alternatively use the Dirac menu in the Audio
settings menu to set the curve for each input. See
"Dirac Curve" on page EN-17.
Note: When Dirac is run for the first time the
curve will be applied to all inputs. Subsequent
curves will not be automatically applied, use the
methods above to choose the required curve for
the input in question.
When Dirac is being used the icon will be
shown on the display.

SA750 DIGITAL FILTERS
The SA750 allows the listener to choose between
a number of digital filters for use in the audio
DAC. Digital filters are required to minimise
unwanted antialiasing distortion in the audio band
but no digital filter is perfect, all are a compromise
between various parameters. These include:
Frequency response – Audio level with respect to
frequency. Ideally this should not vary significantly
between 20Hz and 20kHz.
Phase – The time delay introduced between
reproducing different frequencies within the pass
band of the filter. Ideally this would be as low as
possible (linear phase).
Pre ringing – Additional audio artefacts that
precede the original audio impulse. These are
sometimes thought to be bad as this phenomenon
does not exist in the natural world, so ideally this
should be as low level and last for as short a time
as possible.
Post ringing – Additional audio artefacts that
follow the original audio impulse. Ideally these
should be as low in level and last for as short a
time as possible.
Aliasing – Additional audio artefacts introduced
into the audio band from high frequency signals.
We have chosen our default filter through
a combination of careful measurement and
listening tests and we believe they are the
best compromise to achieve the best listening
experience. However, all of the filters sacrifice
performance of one parameter to improve
another. Therefore, dependant on your choice of
listening material and personal preference, you
may wish to choose one of the other options. Note
that any audible differences are most likely to be
heard with sample rates of 48kHz and below.
Brick Wall (B Wall)
No phase shift, but introduces both pre and post
ringing artefacts.
Corrected Minimum Phase Fast Roll
Off (Corr MinP)
Low pre-ringing and the phase response varies
at higher frequencies. There is more post ringing
compared with linear phase and apodizing filters.
Apodizing (Default)
A compromise between phase, frequency
response and ringing. Its main advantage is that
it removes most of the ringing that has been
introduced upstream in the recording process
when the original material was recorded and
mastered.
Minimum Phase Slow Roll Off (MinP
Slow)
No pre-ringing artefacts but can introduce phase
shifts at higher frequencies. It has less post
ringing than the Minimum Phase Fast Roll Off,
but this is still higher than the linear phase filter
options. Very high frequencies in the last half
octave of the filter pass band will be slightly
attenuated.
Minimum Phase Fast Roll Off (MinP
Fast)
No pre-ringing and the phase response varies at
higher frequencies. There are significantly higher
amounts of post ringing compared with the linear
phase filter options.
Linear Phase Slow Roll Off (LinP
Slow)
Low and equal levels of pre and post ringing. No
phase shifts but can introduce high frequency
aliasing at a higher level than linear phase fast
roll off. Very high frequencies will be slightly
attenuated.
Linear Phase Fast Roll Off (LinP
Fast)
Higher and equal levels of pre and post ringing
compared with linear phase slow roll off. No
phase shifts and with minimal high frequency
aliasing compared with slow roll off.
