ABOUT FIXED-LEVEL OUTPUTS
A fixed-level, or line-level audio output is a steady audio signal
unchanged by adjustments to the PC’s volume control.
•Many PC soundcards have a "Line Out" that is a fixed-level output.
Depending on the fixed output level of the soundcard, this signal may
not be strong enough for your optimal signal strength.
ABOUT VARIABLE-LEVEL OUTPUTS
A variable-level output is an audio signal that changes in relation to the
volume adjustments on the PC. The speaker output on a soundcard is a
variable-level output.
As the volume of the PC goes up and down, so too does the strength of
the audio signal sent to the transmitter. This can affect the quality of the
sound you hear on the home stereo, and may require increasing the
volume level of the audio source to achieve a strong enough audio signal
for use with the Matrix, or decreasing the audio source volume if sound
from the headset is distorted by a too-strong signal.
TROUBLESHOOTING
The following troubleshooting guide outlines possible problems and
corrections associated with the installation and/or operation of a wireless
system. If a problem persists, please call 1-800-732-6866 and a knowledgeable customer service representative will assist you.

TROUBLE CHECKS AND ADJUSTMENTS
No Sound •Check that the outlets the transmitter and receiver are
plugged into are providing power.
•Check that the AC Adapters (F, L) are fully inserted into the
wall outlets and the power cords from the AC adapters (F, L)
are firmly connected to the Power Input Jack (B, H) on the
transmitter and receiver.
•Check that the PC is turned on and providing sound as it
normally would.
•Check that the home stereo volume is turned up.
•If you are using the speaker output on your sound card,
adjust the volume on the PC up as necessary until the
Audio Level Indicator (A) flashes (about half the time) and
sound is heard through the home stereo when the
receiver is tuned.
No Sound/ •Check that the receiver Tuning Indicator (G) is lit. If not,
Distortion/ adjust the Tuning Control (J) until the red indicator light
Static comes on.

TROUBLESHOOTING CONT’D
No Sound/ •Check that the transmitter Audio Level Indicator (A) is flickering
Distortion/ intermittently. If using a fixed output and the light is on solid/
Static flickering very rapidly, or if the light is not on at all, adjust
the PC’s volume control so the light flickers intermittently.
•Change the position of the transmitter’s Frequency Control (D)
to change operating frequency. Then readjust the receiver’s
Tuning Control (J)until the Tuning Indicator (G)comes on.
•Try changing physical location of the transmitter. Locate as
high and free of obstruction as possible. Avoid placing
directly on top of a PC (or other electronic equipment), if
possible.
•Try changing antenna (E, K) position, particularly if you think
you may be near maximum transmitting range.
•Try moving transmitter and receiver closer together. Sending
the signal through certain materials, such as glass, tile, and
metal can decrease the effective transmitting distance of the
system.
•Check that the antenna (E, K) is in the upright position.

TUNE THE RECEIVER
Step 1 : Turn the Tuning Control (J)
until Tuning Indicator (G) lights steadily.
Note:If the Tuning Indicator flashes, try fine-tuning. If the light still
flashes, check the transmitter settings to make sure the signal
is strong enough, as indicated by the steady flashing Audio Level
Indicator on the transmitter. As needed, adjust the transmitter.

MORE FINE-TUNING
If, after fine-tuning, interference in the form of static and/or "drop-outs"
can be heard, adjust Frequency Control (D) and re-tune receiver. (Step 3
above) If sound is distorted, slowly adjust the PC’s volume control to
compensate for a too-strong audio signal. If you are unable to achieve
clear sound, please refer to "Troubleshooting,” pages 8 and 9.
