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

DESCRIPTION
The ADA104 Home Theatre Speaker System is a unique amplified
speaker system that features Stereo or Dolby Pro-Logic Surround Sound
from one TV set top unit and a subwoofer. The set top unit has four
speakers and uses Altec Lansing’s patented side “firing” technology
and algorithms to provide surround sound from the sides, rear and
front (center). One major convenience of the system is the elimination
of wiring separate speakers and the space they require. The
subwoofer has one speaker and produces all low frequencies for full-
bodied sound.
All functions can be controlled manually or by remote control. The set
top speakers are magnetically shielded and therefore will not distort the
TV screen.
The unit has automatic turn-on. When an audio signal is sensed by the
amplifiers, they are activated. If no audio signal is sensed over a
prolonged period, the amplifiers will turn off.
Two inputs are provided. One input is used for an analog DVD output
(or other source) and the other input can be used for playing a CD or
any device that requires audio power amplification.
OPERATION OF THE CONTROLS
The MASTER VOLUME CONTROL has two modes of operation. It is
used to individually set the levels of the subwoofer (SUB), CENTER
and SURROUND functions and after these levels are set, the control
reverts to becoming a master volume control. Above the volume
control are eight LED’s in different colors. The colors indicate the range
of audio power; three green LED’s indicate the lower register of power,
three orange LED’s indicate mid power and two red LED’s indicate
maximum power.
Setting the levels of the (SUB), CENTER, and SURROUND must be done
within a few seconds otherwise the function will revert back to the
MASTER VOLUME control.
SUB (SUBWOOFER)
To set the level of the subwoofer amplifier press this button, a green LED
indicator will turn on. Turn the MASTER VOLUME control to set the
subwoofer level.
CENTER
To set the level of the center amplifier, press this button. A green
LED indicator will turn on. Turn the MASTER VOLUME control to set
center level.
SURROUND
To set the level of the surround amplifier, press this button. A green LED
indicator will turn on. Turn the MASTER VOLUME control to set the
surround level.
MODE
When this button is pressed repeatedly, the mode of operation changes
from STEREO to PRO-LOGIC and back again to STEREO. A two-color
indicator above the button will show amber for STEREO and green for
PRO-LOGIC.
MUTE
When the SUB and SURROUND buttons are pressed simultaneously,
audio is muted. Pressing these buttons again will restore sound. Sound
will also be restored if any other button is pressed.
Note: The NOISE mode used for setting balances can only be accessed
by using the remote control.
REMOTE CONTROL OPERATION
For best results aim the remote control towards the infrared receiver on
front panel of set top speakers. LED’s will indicate function as when unit
is operated manually.
Key# Function Operation
1 ON/OFF Turns the ADA104 unit on and off.
2 MUTE MUTEs sound.
Press again to restore sound.
3 SUB Adjusts SUB level. Use VOL buttons
9 & 10 to adjust level.
4 CENTER Adjusts CENTER level.
Use VOL buttons 9 & 10 to adjust level.
5 SURROUND Adjusts SURROUND level.
Use VOL buttons 9 & 10 to adjust level.
6 STEREO mode Puts unit in STEREO mode.
7 PRO-LOGIC mode Puts unit in PRO-LOGIC mode.
8 NOISE mode Puts unit in NOISE mode. The NOISE
sound will sequence to PRO-LOGIC
(stereo, center surround) channels. This
will allow setting levels and balance.
9 & 10 VOL UP/DOWN Press these buttons to adjust VOL
up/down. Also use these buttons to
individually adjust the SUB, CENTER
and SURROUND levels.

PLACEMENT OF SPEAKERS
For best performance the TV set top speaker should be centered and
brought as far forward on the TV set as is practical. Remove any articles
that can vibrate and cause distortion.
The subwoofer can be placed in any convenient location as far as the
connecting cables will allow. Subwoofer frequencies are non
directional, therefore the subwoofer can be placed on either side of the
TV set. The subwoofer can be forward or back in relationship to the set
top speakers. Best low frequency response is obtained when the
subwoofer is placed on the floor. The subwoofer speaker IS NOT
magnetically shielded and should not be placed in close proximity to
the TV screen; otherwise image distortion may occur.
The TV set top speaker has adjustable feet so that the speakers can be
angled for best directivity of sound.
