Safety Information

1) To prevent fire or shock hazard, do not expose the SSP-25 to water or moisture.

2) Do not place the SSP-25 close to any heat-producing device such as a radiator, stove, etc..

3) Connect the SSP-25 only to an AC source of the proper voltage. The shipping container and the rear panel

serial number tag will stipulate the proper voltage. Use of any other voltage will almost certainly damage the

unit and will void the warranty.

4) Do not open the SSP-25 for any reason, as there are no user serviceable parts inside. An open unit,

particularly if it is still connected to an AC source, presents a potentially lethal shock hazard. Refer all

questions to authorized service personnel only.

5) If the SSP-25 will be out of use for an extend period of time (vacation, etc.), unplug the power cord from the

AC source to prevent any chance of problems from a voltage surge.

Thank You From Everyone At Classé

Thank you for purchasing the Classé Audio SSP-25 Preamplifier/Surround Sound Processor.

We take great pride in offering components that combine exceptional sonic performance and long-term reliability. To

do that, we have invested in extraordinary design and manufacturing facilities. We trust that you will enjoy your

purchase for many years to come.

Classé Design Philosophy

All of our components benefit from the same rigorous design philosophy. The goal is simple: All Classé products

must reproduce music with the harmonic and spatial integrity typical of fine instruments heard in a live, unamplified

performance.

Single Circuit Design

To this end, we make extensive use of carefully optimized versions of the same basic circuit precisely matched to

specific power requirements. This means that all Classé line level components and power amplifiers benefit from

years of refinement. However, our efforts do not stop here.

Listening: The Critical Design Element

Once we determine general circuit values for a particular application, we listen carefully while exchanging and mixing

different parts (transistors, capacitors, wiring, PC boards, etc.) and adjusting specific operating voltages within proper

engineering ranges.

Extended Real-World Lifespan

Every Classé component, even the most affordable, benefits from this painstaking approach. The result is an

optimum balance between the often-conflicting demands of exceptional performance and long-term reliability. Our

most expensive components gain from even tighter tolerance parts and highly segmented and exceptionally robust

power supplies with large reserve-current capabilities.

Our Pride in Manufacturing. Your Pride in Ownership.

We build all of our components to the highest possible standard. From glass-epoxy circuit boards to the massive 3/8”

thick faceplates, every Classé product is a tribute to both the art and science of sound reproduction. We hope that you

derive as much pleasure and satisfaction in using your Classé as we did in producing it.

About This Manual

The Classé SSP-25 is a very sophisticated preamplifier/processor. Even so, although complete

understanding of the SSP-25’s many capabilities may take some study, its elegant design and

intuitive interface invites daily use by even the technically challenged.

We strongly urge you to read this Manual carefully before you connect and use the SSP-25 in

your home theater system. You’ll find answers to almost all of your questions in these pages.

That knowledge will greatly reduce your efforts as you configure your system to take best

advantage of the SSP-25’s enormous potential.

We’ve organized the Manual for both the experienced installer and the novice user.

The Installation Overview (Section 2) is written for those with technical experience. It provides

an inclusive picture of the SSP-25’s capabilities and suggests several effective system

configuration strategies.

The following Sections supply step-by-step instructions to help the less technical user configure

and use the SSP-25 effectively.

As in all such efforts, a little patience will go a long way to reducing the chances for frustration.

Remember, it took many talented people a long time to design the SSP-25 and you can’t be

expected to learn everything about it in one evening!

So relax. And enjoy. You’re about to enter a wonderful world of high-performance surround

sound.

Section 1: Diagrams

Use the pictures in this section as your guide to the SSP-25. 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 important features. Once you read

them, you’ll understand most of the SSP-25’s capabilities.

1.1 Front Panel

1) VIDEO < &>

These pushbuttons select an audio/video source by stepping from AV1 through AV4 (Video >) or from AV 4

back through AV1 (<Video).

These buttons “wrap” to the next input. For example, if you are enjoying the AV4 input, pressing “Video >“ will

step to AV1. Conversely, pressing “<Video“ while using AV1 will select AV4.

If you press either the “<Video“ or “Video >“ button while listening to an audio-only input, the SSP-25 will

deselect the audio-only input and select the previous or next AV input from the one last used.

(See *NOTEs below in “2) AUDIO<& >”)

2) AUDIO < &>

These pushbuttons work the same way as the Video <& >buttons described above. However, they select an

audio-only source. They “wrap” from AUD1 to AUD3 (<Audio) and from AUD3 to AUD1 (Audio >), though you

will notice that pressing the <or >button when the selected input is AUD3 or AUD1 deselects the AUDIO

ONLY inputs.

*NOTE: When selecting an audio only input the last used AV input LED remains lit, though the AV input is

inactive.

*NOTE: When you wish to return to listening to and watching an AV input after listening to an audio-only input

you may press a <VIDEO or VIDEO> button to move to the previous or next AV input. The currently active

AUDIO ONLY input LED will extinguish and the selected AV input will be active. You may also press the

<AUDIO or AUDIO> button once, twice or three times until the AUDIO ONLY LEDs are no longer lit. Each time

you press the <or >button the previous or next input is selected, unless AUD3 or AUD1 is selected. Pressing

the < button when AUD1 is selected or the >when AUD3 is selected, causes the AUDIO ONLY inputs to be

deselected and the currently lit AV input to become active again.

SSP-25 Front Panel

3) AUDIO and VIDEO SOURCE LED INDICATORS

These red LEDs show the active input. The Input LED will glow red when that input is directed to the Main

outputs. The selected input is always directed to both the Main and the Record outputs. (See Sections 2.2

and 6.7 for further details.)

4) STANDBY (“On/Off”) BUTTON

Although this pushbutton seems to be a normal “On/Off” control, it is actually more sophisticated. When the

SSP-25 is plugged into a live AC outlet and the rear-panel power switch is in the “On” position, this push-

button activates all of the SSP-25’s audio and video circuitry and displays. The next push turns off all circuits

except for basic elements such as the central microprocessor and remote control sensors.

5) STANDBY (“On/Off”) LED INDICATOR

This LED glows green when the SSP-25 is in Standby or “Off” mode. It does not glow at all when the SSP-25

is fully activated.

*NOTE: When the button is pushed to activate the SSP-25 the standby LED goes out and the green MUTE

LED is briefly lit. The information display also lights with a “Classé SSP-25” readout. As soon as the circuitry

becomes active the MUTE LED goes out, the red LED(s) in AUDIO and/or VIDEO light, and the display

changes to briefly identify the active input. The display changes immediately to continuously identify the type of

signal (analog, digital) in the top line and the decoding method in the lower line.

6) INFORMATION DISPLAY

The two lines of information displayed, and the lit LEDs on the SSP-25 combine to provide a comprehensive

view of its current operating parameters. All set-up procedures are also performed utilizing the panel display.

The first line functions as a headline, displaying selected input, type of input signal, or lack of signal, while the

second line displays mode, output level, balance, and so forth.

On the left side of the display window are printed CLIP,OVER,REF,and THX. Clip, Over and Ref are used as

indicators when setting the proper input levels of the left channel of the analog audio inputs. Their use is

explained in section 5.4.6. THX lights as a notifier when THX playback is selected as a decode mode.

On the right side of the display window are printed CLIP,OVER,REF,and COMP. Clip, Over and Ref are

used as indicators when setting the proper input levels of the right channel of the analog audio inputs. Their

use is explained in section 5.4.6. COMP lights when Compression, better known as “night mode” is selected,

as explained on page 15.

SSP-25 Front Panel

7) MODE BUTTONS < & >

These buttons step back and forth through the SSP-25’s operating modes in the following sequence:

DTS® Cinema, DTS® Music, Analog Bypass, Mono (Center), Stereo, Stereo Surround, Dolby Pro Logic®,

Dolby Digital® (AC3). Utilizing the two buttons you can quickly arrive at the mode you desire.

8) MUTE BUTTON

This button fully mutes the SSP-25’s main outputs. A second push restores the previously selected operating

levels. Record output is unaffected. The Mute button provides a convenient way to lower the volume when

answering the telephone.

*NOTE: Turning the volume up with the volume knob will remove muting, but turning down the volume while in

mute mode will not remove muting, but when muting is removed the new lower volume level will be present.

Muting can be removed either with the mute button or by turning up the volume slightly.

9) MUTE LED INDICATOR

This LED glows green when the SSP-25 is in the mute mode.

10) MASTER LEVEL CONTROL

This large knob changes the relative levels of all active main room channels simultaneously. Each

loudspeaker’s relative loudness stays in perfect balance with all other speakers as programmed during setup.

The Main Information Display shows the master level setting in numbers from “Volume: -80” (virtually no

output) to “Volume! +35” (maximum output).

1.2 Rear Panel

1) ANALOG AUDIO INPUTS (See *NOTE 1 below: Page 13)

a) AUD1 (Line level, balanced: XLR x 2 OR line level, single ended: RCA x 2) (PIN 2 = HOT)

b) AUD2 (Line level, single ended: RCA x 2)

c) AUD3 (Line level, single ended: RCA x 2)

e) AV1 (Line level, single ended: RCA x 2)

f) AV2 (Line level, single ended: RCA x 2)

g) AV3 (Line level, single ended: RCA x 2)

h) AV4 (Line level, single ended: RCA x 2)

These analog audio inputs accept a line level signal from any component equipped with the appropriate output

circuitry. With the partial exception of “a) AUD1,” the balanced input requires three-pin XLR connectors (Pin

2 = Hot), all analog audio inputs are single ended circuits with RCA-style terminations. The SSP-25 has no

internal provisions for MM or MC phono amplification/RIAA equalization but accepts line level outputs from a

wide variety of external step-up devices if desired.

2) DIGITAL AUDIO INPUTS (See *NOTE 1 below: Page 13)

a) AUD1 (multi-format S/PDIF: RCA x 1)

b) AUD2 (multi-format S/PDIF: RCA x 1)

c) AUD3 (multi-format S/PDIF: RCA x 1)

d) AV1 (multi-format S/PDIF: RCA x 1)

e) AV2 (multi-format S/PDIF: RCA x 1)

f) AV3 (Multi-format S/PDIF: RCA x 1)

g) AV4 (multi-format S/PDIF: Toslink x 1 OR Multi-format S/PDIF RCA x 1)

h) AV4 AC3 (Multi-format S/PDIF: RCA x 1) USED TO PLAY AC3 ENCODED LASER DISKS ONLY

Except partially for “g) AV4,” these digital audio inputs accept standard S/PDIF digital signals via 75 ohm

coaxial cables with RCA-style connectors. The AV4 input also uses a Toslink-style optical connector for digital

source components with this type of digital output. AV4 is designed to be used with the optical digital output of

many laser disc players and/or DVD players.

3) VIDEO INPUTS

a) AV1 (Composite: RCA x 1)

b) AV2 (Composite: RCA x 1)

c) AV3 (Composite: RCA x 1)

d) AV4 (Composite: RCA x 1)

e) AV1 (S-Video: mini-DIN x 1)

f) AV2 (S-Video: mini-DIN x 1)

g) AV3 (S-Video: mini-DIN x 1)

h) AV4 (S-Video: mini-DIN x 1)

These inputs accept video signals from various video source components. Inputs a) through d) accept a composite

video signal while inputs e) through h) accept S-Video (Y/C) signals.
