ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)
DEVICE HANDLING
This unit contains ESDS devices. We recommend the following precautions when repairing,
replacing or transporting ESDS devices:
•Perform work at an electrically grounded work station.
•Wear wrist straps that connect to the station or heel straps that connect to conductive
floor mats.
•Avoid touching the leads or contacts of ESDS devices or PC boards even if properly
grounded. Handle boards by the edges only.
•Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert
unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags,
bubble wrap or plastic trays.
Product Description Companion®5
The Companion 5 is a multi-channel multimedia speaker system connecting to personal
computers via a USB 2.0 interface. No additional sound card is required to enjoy 5.1-channel
audio
content from the host PC. The two speaker arrays combined with advanced audio processing
algorithms provide a spacious presentation of stereo content and a compelling experience with
multi-channel content. A control module brings the master volume control, simple touch mute
control and jacks for an auxiliary analog stereo input and headphones.
The Companion 5 system consisting of the following major components:
1. Bass speaker enclosure with Woofer
2. Control Module with an 8-foot (2.4M) cable.
3. Two two-element speaker arrays with integrated cables, uniquely keyed and identified for
left and right locations.
The speaker arrays are mounted on removable speaker stands that are engineered to position
the speakers at the correct height and angle on either side of a computer monitor. The
transducers contained in the speaker enclosures may not be replaced. The speaker grills are
glued in to prevent movement during shipping.
The integrated speaker cable is hard wired into the speaker enclosure and is not removable.

DISASSEMBLY PROCEDURES
Disassembly
The following procedure shows the disassem-
bly of the bass module to allow access to the
DSP and I/O boards.
Note: The cabinet is glued together prevent-
ing any type of internal repair beyond the
boards. The woofer and the transformer are
both inside the cabinet and cannot be re-
placed.
1. DSP board removal
1.1 Remove the four phillips-head screws
from the rear cover.
1.2 Pull the rear cover down and remove the
cables connected to J2, J21 and J22 on the
I/O board and J8000 from the DSP board.
1.3 Remove the four Phillips-head screws
located to the left and right of the heatsink.
1.4 Remove the cables connected to J350
and J10, this allows the heatsink and DSP
board to pull away from the bass module
cabinet.

18
DISASSEMBLY PROCEDURES
2. I/O Board Removal
2.1 Use a small flat-head screw driver to
pull the Bass control off of the rear cabinet.
2.2 Remove the three Phillips-head screws
that secure the I/O board in place.
2.3 Remove the plastic bracket that secures
the I/O board in place.
1.5 Remove the four 6-32 TORX screws that
holds the heatsink bracket in place.
1.6 Separate the heatsink, heatsink bracket
and DSP board.

Audio Test Procedures
Note: There are two different test procedures
for the Companion 5.
1. Audio test
2. USB light up and play test
Audio test
Equipment required:
1. Audio Signal Generator
2. Oscilloscope
3. Digital Multimeter
Test Set up
1. Connect the satellites to the output jacks on
the bass module.
2. Connect the control pod to the 10 pin input
connector on the bass module (the control pod
must be connected before power is applied).
3. Connect the power cord to an AC outlet.
4. Connect a signal generator to the audio
input cable and connect the cable to the input
jack on the control pod.
1. Bass Module Air Leak test
1.1 Apply a 100 mVrms, 55 Hz signal to the
input of the bass module.
1.2 Set the volume knob on the control pod to
maximum (fully clockwise), and set the bass
compensation control to it’s center detent (flat)
position.
1.3 Listen carefully for air leaks along all glued
joints, around the heat sink, connectors and at
the woofer mounting location.
PASS if no audible air leaks can be heard at a
distance > 1 ft from any exterior surface of the
Bass module.
FAIL if air leaks can be heard at a distance
> 1 ft from any exterior surface of the Bass
module.
1.4 Repair any air leaks around the heat sink
and connectors. Replace any bass module
that has air leaks around the bass box or
woofer mounting location.
2. Bass Module Sweep Test
2.1 Apply a 100 mVrms, 10 Hz signal to the
input of the bass module.
2.2 Set the volume knob on the control pod to
maximum (fully clockwise), and set the bass
compensation control to it’s center detent (flat)
position.
2.3 Listen carefully as you sweep the bass
module from 10 Hz to 500 Hz, then from 500
Hz to 10 Hz.
2.4 Listen carefully for buzzes, rattles, or other
extraneous noises from the woofer, cabinet,
plastic trim parts, or heat sink. A slight
whooshing sound from the port (at approxi-
mately 45 Hz) is acceptable.
2.5 Repair any noise heard from around the
heat sink and connectors. Replace the bass
module if it has noises from the woofer or
cabinet area.

20
Audio Test Procedures (continued)
3. Bass Module, Bass Compensation Test
3.1 Apply a 90 mVrms, 100 Hz signal to the
input of the bass module.
3.2 Set the volume knob on the control pod to
maximum (fully clockwise), and set the bass
compensation control to it’s center detent (flat)
position.
3.3 Rotate the bass compensation control fully
clockwise and counter clockwise.
3.4 Verify that the bass level cleanly increases
and decreases in level.
4. Satellite Sweep Test
4.1 Apply a 100 mVrms, 100 Hz signal to the
input of the bass module.
4.2 Set the volume knob on the control pod to
maximum (fully clockwise), and set the bass
compensation control to it’s center detent (flat)
position.
4.3 Use the list below to sweep the frequency
to the input. Listen carefully for buzzes, rattles,
or other extraneous noises from the Twiddler™
speakers, plastic satellite enclosure, grille, or
internal wires.
Sweep Range Input Signal
100Hz to 500Hz 100mVrms
500Hz to 2kHz 50mVrms
2kHz to 5kHz 25mVrms
4.4 Replace any satellite that is found to be
defective.
5. Satellite Air Leak Test
5.1 Apply a 60 mVrms, 300 Hz signal to the
input of the bass module.
5.2 Set the volume knob on the control pod to
maximum (fully clockwise), and set the bass
control to it’s center detent (flat) position.
5.3 Listen carefully for air leaks along edges
of the satellite and near the grille where the
Twiddler speaker is installed.
5.4 Replace any satellite that is defective.
6. Control Pod Functional Test
6.1 With the system completely set up, con-
nect power.
6.2 Set the volume knob on the control pod to
maximum (fully clockwise), and set the bass
control to it’s center detent (flat) position.
6.3 Touch the center of the control pod . Verify
that the LED turns from green to orange and
orange to green with each touch.
6.4 Verify that the sound is muted and un-
muted when the LED changes color and that
there is no audible pop when switching from
mute to un-mute.
6.5 Rotate the control pod ring, verify that the
volume increases and decreases and that the
ring moves smoothly.
6.6 Replace any control pod that is defective.
