Troubleshooting
The following troubleshooting guide takes you through some of the more common problems
associated with the installation and/or operation of a wireless system. If the problem persists,
please call toll-free at 1-800-732-6866 or visit www.acoustic-research.com.
Issue: Cause and solution:
No sound • Check that the transmitter AC power adapter is fully inserted into the wall outlet
and the power cord from the AC adapter is fi rmly connected to the transmitter
power input jack.
• Confi rm that the speaker is turned on and tuned to the transmitter—the indicator
light on the back of the speaker should be solid blue (not blinking).
• If you’re using the power adapters, confi rm that both (for the speaker and for the
transmitter) are fully inserted into their wall outlets and the adapter power cords
are fi rmly connected to the power input jacks on the transmitter or speaker.
or
• If you’re using batteries for the speaker, check that they are fresh and inserted
with correct polarity (+, –).
• Check that the audio source component (stereo, MP3 player, etc.) is turned on and
transmitting sound as it normally should.
• Make sure the volume on your audio source is turned up.
• Check that the speaker volume is turned up.
• If you are using a Tape 2 Monitor output from your receiver/amp as the audio
output, check that you have pressed the Tape Monitor/Tape 2 button on the front
of the receiver. This will turn on the Tape 2 outputs, which may not have been
active.
Issue: Cause and solution:
Sound is
distorted or
has static
• When using battery power, make sure the batteries are fresh and replace if
necessary.
• Check that the speaker’s indicator light is solid blue (not blinking) when an audio
source is connected to the transmitter
• Change the position of the channel select switch (1, 2 or 3) to change the
operating frequency. Then press the AutoScan button on the speaker’s back panel
to make the speaker retune.
• Change the location of the transmitter. Place it as high and away from
obstructions as possible. Avoid placing the transmitter directly on top of or behind
a TV.
• Move the transmitter and speaker closer together. Sending the signal through
certain materials, such as glass, tile, and metal, can decrease the effective
transmitting distance of the system.
Transmitter
• Omni-directional 900MHz broadcast
• Effective transmitting range: up to 150 ft. (45m)*
• Phase-locked loop circuitry (PLL)
• 3 selectable broadcast frequencies
• Stereo audio input
*Maximum range; results may vary according to
environment.
Speaker
• Push-button, auto-lock tuning
• 2-way acoustic design:
• 2” tweeter, 3” woofer
• 10 Watt rated internal amplifi er
• Omni-directional receiver
• Frequency response: 40Hz - 15kHz
• Left/Mono/Right switch
• Operates using supplied AC adapter or six (6)
AA batteries (not included)
Turning the Speaker Off
1. Press the On-Off button on the back of the speaker to turn the speaker off.
2. Confi rm that the speaker is off by verifying that the indicator light on the speaker’s back
panel is no longer illuminated.
