triangle, is intended to alert the user to the presence of
uninsulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of
electric shock to persons.

CAUTION: TO PREVENT THE RISK OF ELECTRIC SHOCK, DO
NOT REMOVE COVER (OR BACK). NO USER- SERVICEABLE
PARTS INSIDE. REFER SERVICING TO QUALIFIFED SERVICE

SAFETY INSTRUCTIONS

The FCC Wants You to Know

This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and

on, the user is encouraged to try to correct the interference by one or more of
the following measures:
a) Reorient or relocate the receiving antenna.
b) Increase the separation between the equipment and receiver.
c) Connect the equipment to an outlet on a circuit different from

that to which the receiver is connected.

d) Consult the dealer or an experienced radio/TV technician or help.

FCC Warning

Modifications not expressly approved by the manufacturer could void the user
authority to operate the equipment under FCC Rules.

RF Breakthrough Advisory

If this product is placed too close to a high level source of RF energy, RF breakthrough may be experienced which can cause some audio
disturbance. If this happens, move the product as far away as possible from the source until the disturbance is eliminated. Using an audio input
cable with a high percentage of shielding is also helpful in reducing or eliminating interference.

The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important

or position does not interfere with its proper ventilation. For example, the appliance should not
be situated on a bed, sofa, rug, or similar surface
that may block the ventilation openings; or placed in a built-in installation, such as a closed
bookcase or cabinet that may impede the flow of air through the ventilation openings.
Heat — The appliance should be situated away from heat sources such as radiators, heat
registers, stoves, or other appliances (including amplifiers) that produce heat.
Power Sources — The appliance should be connected to a power
supply only of the type described in the operating instructions or as marked
on the appliance.

Power-Cord Protection — Power-supply cords should be routed so that they are not likely to
be walked on or pinched by items placed upon or against them. Pay particular attention to
cords at plugs, convenience receptacles, and the point where they exit from the appliance.
Grounding or Polarization — The precautions that should be taken so that the grounding or
polarization means of an appliance is not defeated.
Cleaning — The appliance should be cleaned only with a polishing cloth or
a soft dry cloth. Never clean with furniture wax, benzine, insecticides or other volatile liquids
since they may corrode the cabinet.
Non-Use Periods — The power cord of the appliance should be unplugged from the outlet
when left unused for a long period of time.
Object and Liquid Entry — Care should be taken so that objects do not fall and liquids are
not spilled into the enclosure through openings.
Damage Requiring Service — The appliance should be serviced by qualified service
personnel when:

• The power-supply cord or the plug has been damaged.

• Objects have fallen, or liquid has been spilled into the appliance.

• The appliance has been exposed to rain.

• The appliance does not appear to operate normally or exhibits a marked change in
performance.

• The appliance has been dropped or the enclosure damaged.

Introduction

The ADA880 is a technologically advanced multimedia amplified speaker system featuring Dolby Digital AC3 and Dolby Pro-Logic surround

sound and stereo reproduction. The amplifier inputs can simultaneously operate on analog and digital (S/PDIF)* audio signals.

The unit is comprised of a subwoofer and two satellite speakers. This combination provides surround sound on a desktop by
utilizing side firing speakers. For enhanced surround sound the top speaker portion of each satellite can be separated and placed on
a provided stand with long speaker wires. This enables the separated speakers to be placed for best surround sound performance.
Equalizer circuitry automatically resets to conform to the changes that take place when the speakers are separated.

The satellite speakers are magnetically shielded and can be placed close to a monitor without disturbing images. The speaker in the
subwoofer is not magnetically shielded and should not be placed close to a monitor.

Subwoofer frequencies are non directional, therefore, the subwoofer does not have to be located in any particular relationship to the
satellite speakers. Placing it on the floor close to a wall, corner of a room or under a desk gives excellent results.

The main satellite speaker has status indicators to show the various conditions of operation. Amaster volume control is used to
separately adjust bass, center, surround and treble settings. Once the individual functions are set, the control reverts back to
becoming a master volume control. Aremote control unit is supplied that can access all the manual functions. The remote control
has a mute function that is not available when using the controls manually.

The AC3/PRO-LOGIC/STEREO decode circuits operate automatically. If the unit is in the STEREO or PRO-LOGIC mode and an
AC3 signal appears at the input of the amplifier, the circuitry automatically switches over to AC3. This and other automatic features
are explained under “Using the Speaker System.”

If analog and digital signals appear at the input of the amplifier, the analog signal is automatically reduced in volume level.
