power adapter. The CHRG. indicator on the front of the speaker will illuminate.
Warning: DO NOT power the speaker with the AC power adapter if you installed
alkaline or other non-rechargeable batteries – this could cause the batteries to leak,
which would damage the speaker.
More Helpful Information
About Fixed-Level Audio Outputs
A fixed-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, Tape 1, and Tape 2 outputs, or VCR audio output connections These outputs are
frequently marked on A/V equipment as ‘TAPE OUTPUT,’ ‘TAPE OUT,’ ‘TAPE REC,
or ‘TAPE RECORD or REC OUT.’
Please note: Jacks labeled PHONO, CD, LD, DVD or tape or VCR playback (PB) are
INPUTS and will not work with the transmitter.
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 VariableLevel Audio Outputs” on the next page). Outputs from VCRs are almost always fixed.
Hint: When connecting to the audio outputs of a VCR, remember that the VCR must be
playing a tape or showing a TV channel for sound to be produced.
Hint: If your VCR (or other audio source with RCA jacks) only has a single audio
output, you will need another RCA “Y” cable. It differs from the “Y” Cable Adapter
included with this speaker. It will have a single male RCA plug and 2 female RCA jacks.
Connect the dual RCA plugs from the included “Y” cable adapter to the 2 female RCA
jacks on the second “Y” cable, and then connect the single male RCA plug of the second
“Y” cable to the single audio output of the VCR.
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 fixed, refer to the TV instruction manual. Some TVs
have outputs that can switch between variable and fixed. When given a choice, fixed 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 firmly connected to the transmitter
power input jack.
• Confirm that the speakers are turned on and tuned to the transmitter—
the STDBY./TUNED indicator light on the front of each speaker should be
illuminated blue.
• If you’re using the power adapters, confirm that all three (for both speakers
and for the transmitter) are fully inserted into their wall outlets and the adapter
power cords are firmly connected to the power input jacks on the transmitter or
speaker.
or
• If you’re using batteries, check that they are fresh and inserted with correct
polarity (+, –).
• Check that the audio source component (stereo, TV, etc.) is turned on and
transmitting sound as it normally should.
• Check that the speaker volumes are 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:
No sound/
distortion/
static
• When using battery power, make sure the batteries are fresh and replace if
necessary.
• Check that the speaker STDBY./TUNED indicator is illuminated blue.
• Change the position of the channel select switch (1, 2 or 3) to change the
operating frequency. The speaker will detect the loss of signal and retune
automatically. You can also press the Power/Volume/Tuning control once 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.
