Acoustic Research AW851 - Manual (Page 2)

About Variable-Level Audio Outputs:
A variable-level output, such as a headphone jack or certain RCA-type outputs,
provides an audio signal that changes with the volume level set on the audio source.
As the volume of the audio source is adjusted up and down, so is the audio signal
strength sent to the transmitter. This can affect the quality of sound generated by the
speaker, and may require an adjustment of the volume level of the audio source to
produce a signal strong enough for the transmitter.
Hint: On most bookshelf-type or compact stereo systems, inserting a headphone
plug into the headphone jack results in automatic cutoff of the regular, or hard-wired
speakers.
Hint: Most TVs, regardless of age or price, have variable outputs. If you are unsure
which of your TV audio outputs is fi xed, refer to the TV instruction manual. Some
TVs have outputs that can switch between variable and fi xed. When given a choice,
fi xed is always recommended.
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.araccessories.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 front of the speaker should be solid blue (not blinking).
• If the speaker is on a switched outlet, make sure the outlet is on.
• 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.
No sound/
distortion/
static • Check that the speaker’s indicator light is solid blue (not blinking).
• Change the position of the channel select switch (1, 2 or 3) to change the operating
frequency. Then press the Auto Scan button on the bottom of the speaker 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 closer to the speaker. Sending the signal through certain
materials, such as glass, tile, and metal, can decrease the effective transmitting
distance of the system.
Bulb doesn’t
light • If the lantern/speaker is on a switched outlet, make sure the outlet is on.
• Make sure the light on/off switch on the bottom of the lantern/speaker is switched
on.
• Make sure the bulb hasn’t burned out. Try a new bulb in the lantern/speaker.
• If the above solutions don’t work, turn off power to the outlet at the circuit box and
make sure the lantern/speaker is wired correctly.

circuit box and rewire the lantern/speaker, making sure to match the black to black
wire, white to white, and ground to ground.
More Helpful Information
About Fixed-Level Audio Outputs
A fi xed-level, or line-level, audio output is considered ideal since it provides an audio
signal unchanged by adjustments to the audio source volume control.
Hint: Fixed-level audio outputs from stereo receivers/amps will typically be
designated as Tape (or Record) outputs or DVR/DVD-R audio output connections.
Fixed-level outputs from TVs are usually marked as ‘Constant,’ ‘Fixed,’ or ‘Select.’ If they
are not marked as such, they are probably variable outputs (see “About Variable-Level
Audio Outputs” below). Outputs from DVD players are almost always fi xed.
Hint: When connecting to the audio outputs of a DVD player, remember that the DVD
player must be showing a TV channel for sound to be produced.

1. Press the Speaker On/Off button on the right side of the speaker
to turn it on. The indicator light on the front of the speaker blinks
while the speaker is tuning to the transmitter. The indicator light
turns solid blue when the speaker is tuned to the transmitter—you
should hear sound coming from the speaker now.
Note: If the speaker is on a switched outlet, make sure the outlet is
on.
Note: If the speaker is not tuned or if the transmitter is not
connected properly, the indicator light will continue blinking. If this
occurs, please see the troubleshooting section of this manual.
2. Adjust the volume on the speaker as desired.
3. Set up the speaker for mono or stereo operation using the switch on the right side
of the AW851 speaker.
a) Monaural operation: The monaural mode (mono) is recommended when using a
single AW851 by itself. For monaural operation, set the L/M/R switch to “M” on
the speaker.
b) Stereo operation: You need an additional AW851 speaker for the stereo option.
Set the L/Mono/R switch to “L” on the speaker located to the left from the
listener, and set the other speaker to the “R” position.
Notes:
A single AW851 transmitter can send its signal to more than two speakers. All you need
to do is tune the speakers to the single transmitter.
The speaker automatically retunes if it loses the transmitter’s signal. You can also press
the Auto Scan button on the bottom of the speaker to retune the speaker at any time.
The transmitter turns off automatically if there is no audio signal present for a prolonged
period.
Interference in the form of static and/or distortion can sometimes be heard. If this
occurs, confi rm the transmitter/speaker adjustments and indicators. If the problem
persists, refer to the Troubleshooting section of this manual.
Pairing the Speaker System
2. Set the channel select switch on the back of the
transmitter to one of the transmitter’s three broadcast
frequencies: 1, 2 or 3. If you experience poor reception
or interference, try choosing a different frequency by
moving the channel select switch to another position.
When the transmitter is receiving an audio signal and is
ready, the SIGNAL indicator turns solid green.
Turning the Speaker Off
1. Press Speaker On/Off button on the bottom 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
front panel is no longer illuminated.
