SECTION 1:

INPUTS, OUTPUTS AND CONTROLS

Use the drawings in this section as your guide
to the SSP-75. They show the locations of all
controls, inputs, outputs, remote keys – in short,
everything you need to know about your new
preamplifier/surround sound processor. Read the
notes under each diagram carefully. You'll find
capsule explanations of all its important features.
Once you have read them, you'll understand most
of the SSP-75's capabilities.

1.1 FRONT PANEL

View page to the Left For Front Panel Controls
and Readouts

1.1.1 MODE BUTTON

THESE buttons select up and down from the
available SSP-75 operating modes the mode
(format) that will be utilized for the audio portion
of the currently selected SOURCE. Selection is made
in the following sequence: Cinema, Music, Party,
Mono (Center), and Stereo. Utilizing the two
buttons you can quickly arrive at the mode you
desire. When in Cinema mode either DOLBY PRO
LOGIC, DOLBY DIGITAL (AC3) or DTS is selected
automatically, depending upon the program
material available on the active audio input.
1.1.2 INPUT–AUDIO BUTTON
THESE two buttons select up and down from all
the available analog or digital AUDIO INPUTs the
input that will be utilized for the currently selected
SOURCE. The buttons would generally only be used
during setup to attach the correct AUDIO input
to one of the twelve SOURCEs. (SOURCEs may
be personalized but they are, by default: AUDIO 1
through AUDIO 6 and VIDEO 1 through VIDEO 6).
The audio inputs 'wrap' from COAXIAL1, to
COAXIAL 2, to COAXIAL 3, to COAXIAL 4, to
OPTICAL 1, to OPTICAL 2, to AES/EBU, to RF
DEMOD (For external RF demodulator), to ANALOG
and to EXT 5.1. (EXT 5.1, meaning External 5.1,
is utilized to input the six preprocessed analog
channels available from some DVD players. These
analog signals go directly through the SSP-75
without being processed in any way).
There are twelve two channel Analog audio inputs.
Each pair is permanently attached to a particular
AUDIO (1 – 6) or VIDEO (1 – 6) input. (Analog 6
input is only Balanced (XLR) while all the others
are pairs of single-ended (RCA) connectors). When
ANALOG is selected only the attached analog input
is played. Any of the seven digital inputs may be
attached to any of the twelve available SOURCEs.
One digital input may in fact be attached to
multiple SOURCEs. (Each SOURCE may have
attached only one digital audio (or none) plus the
associated analog audio input. The SSP-75 will
automatically play the 'live' audio source for any
selected source. If both analog and digital audio
sources are 'live' it will automatically select and play
the digital input unless ANALOG has been selected
as the default audio input.
1.1.3 INPUT–SOURCE BUTTON
THESE pushbuttons work the same way as
the Audio buttons described above; selecting
an audio or an audio/video SOURCE for output
to the amplifiers and video projector (or TV).
These pushbuttons select an audio/video SOURCE
by stepping from VIDEO 1 through VIDEO 6 or
an audio-only SOURCE from AUDIO 1 through
AUDIO 6.
Each press of these buttons changes the source to
the next or previous input. For example, if you are
enjoying the AUDIO 1 input, pressing the upper
'SOURCE' button will step to AUDIO 2. Conversely,
pressing the lower 'SOURCE' button while using
AUDIO 1 will select VIDEO 6. (Any of the twelve
'SOURCE' selections can be renamed utilizing
functions only available on the remote control
wand).
1.1.4 CLIP AND FORMAT LED INDICATORS
CLIPPING: The top LED of these four LEDs glows
red to indicate the SOURCEs analog input is being
clipped (over-driven). This event would indicate the
sensitivity of the driven input is set too high.
FORMAT: The remaining three LEDs indicate the
Surround Format of the signal on the audio input.
The SSP-75 recognizes the signal on the digital or
analog input and automatically selects the correct
format to use to properly replay the signal. The
three LEDs indicate which method is present:
Dolby Pro logic, Dolby Digital or dts.

1.1.5 STANDBY BUTTON AND LED INDICATOR

When the green LED is lit the 'Main' outputs of the
SSP-75 are in 'Standby' or 'Off'. When in Standby
the 'Main' 12 volt DC trigger is Off and there is no
output from the Main outputs. The processor is
waiting for a signal from the remote control or
from the standby button to turn on. When the
button is pushed to activate the SSP-75 the standby
LED goes out and the display also lights briefly with
a 'Classé SSP-75' readout. All circuits are powered
on, and 12 volts DC is present at the Main 3.5 mm
DC jack on the rear panel.
The remote Zone can continue to play when the
Main Zone is in Standby, and the Zone can put into
or removed from Standby. Different SOURCEs can
be selected for the remote Zone output when
the remote Zone is on. There is no 'Standby'
indication on the front panel for the remote Zone.
