INTRODUCTION
Thank you for your purchase of 900 MHz Wireless Speakers by Advent. These
speakers eliminate the most difficult aspect of installing additional speakers to any
location in your home - running and concealing hundreds of feet of unsightly
speaker wire. Like FM radio, the Advent Wireless Speaker System 900 MHz signals
travel with ease through walls, floors, ceilings and other obstacles, delivering high-
quality stereo sound virtually anywhere in or about the home. Resonator-controlled
circuitry for drift- and static-free reception, coupled with outstanding range - up to
300 feet* - make the possibilities for your enjoyment of the Advent Wireless
Speaker System virtually unlimited.
The Advent Wireless Speaker System is compatible with most potential audio
sources, i.e. TVs, VCRs, stereo receivers/amps, personal stereos, boom boxes, DSS
receivers, and individual stereo component pieces (CD players, cassette players,
etc.) The contents of this manual cover various connection options and detailed
operating procedures for making the Advent Wireless Stereo Speaker System a
valued part of your lifestyle. If, after having reviewed the instructions, you have any
questions, please contact our Customer Service Department at 1-800-732-6866.

3. Plug the 3.5mm mini plug from the “Y” Cable Adapter into the headphone jack
(as needed, use the Headphone Adapter Plug (Cl) to convert the 3.5mm plug to a
l/4” plug).
Note: If you select Option 1 or Option 2 to connect the transmitter, the audio level will be
fixed or valiable, depending on your equipment If you select Option 3, the audio
-revel will be variable.
A BOUT F IXED -L EVEL O UTPUTS
A fixed-level, or line level audio output is considered ideal since it provides an
audio signal unchanged by adjustments to the audio source (stereo, etc.) volume
control.
Hint:
Hint:
Hint/
Fixed-level audio outputs from stereo receivers/amps will typically be designated
as Tape, Tape I, and Tape 2 outputs, OAT (digital audio tape) outputs, VCR audio
output connections, and auxiliary audio outputs. Tape, Tape 1, Tape 2 and OAT
outputs are usually marked as
‘TAPE OUTPUT,’ ‘TAPE OU7;’ ‘TAPE REC,’OR ‘TAPE
RECORD.’ Jacks designated for phono, CD, LO, DVD or tape playback (PB) are
inputs and will not work for purposes of installing 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
Variable-Level Outputs, ” next page).
Outputs from VCRs are almost always fixed.
When connecting to the fixed audio outputs of a VCR, remember that for the
wireless system to work, the VCR must be active. In other words, turn the TV on
to the channel you would normally use to watch a videotape (channel 3 or 41, turn
the VCR on, then press the TV/VCR button on your VCR remote control one time to
make the VCR the controlling piece of equipment. At this point, you can watch TV
or a VHS tape through the VCR. When changing TV channels, remember to do so
through the VCR. This configuration gives you independent volume control
through your TV (using the TV remote control) and at the speakers.
If your VCR (or other RCA-type audio source you are connecting to) is mono (a
single audio output), you need to acquire an RCA “Y” Cable. It differs from the ‘7”’
cable included in this kit. It will have a single male RCA plug and 2 female RCA
jacks. Attach the dual RCA cables from the transmitter to the 2 female RCA jacks
on the ‘7”’ cable, then connect the single male RCA plug of the “Y” cable to the
single audio output of the VCR.
A BOUT V ARIABLE -L EVEL O UTPUTS
A variable-level output, such as a headphone jack, provides an audio signal to the
transmitter that changes in relation to volume adjustments on the audio source. As
the volume of the audio source goes up and down, so too does the audio signal
strength sent to the transmitter. This can affect the quality of sound you hear at the
speakers.

Hint:
/fin t:
On most bookshelf-type or compact stereo systems, inserting a headphone b/ug
into the headphone jack results in automatic cutoff of the regular, or hard-wired,
speakers.
Most TVs, regardless of age or price, have variable outputs. If you are unsure
which, if any of your outputs is fixed, refer to the TV instruction manual. Some
TVs have outputs that can switch between variable and fixed. Refer to the TV
instruction manual. When given a choice, fixed is a/ways recommended.

For stereo operation, set the Left/Mono/Right Switch (C) to “Left” on one speaker
and “Right” on the other speaker. For monaural operation at each speaker, set the
Left/Mono/Right Switch to “Mono” on each speaker
Note: If you use one speaker at one location and the other at another location (i.e. two
different rooms), Advent recommends the “Mono” setting for best sound
reproduction.
OPTIONAL SPEAKER MOUNTING BRACKETS
Optional Speaker Mounting Brackets (T) are available to wall mount your AW870
speakers.
TROUBLESHOOTING
The following troubleshooting guide takes you through some of the more common
problems and corrections associated with the installation and/or operation of a
wireless system.
TROUBLE
C HECKS AND A DJUSTMENTS
No Sound Confirm that the Transmitter AC Adapter (0) is inserted into the wall
outlet and the power cord from the AC adapter is firmly connected to
the Transmitter Power Input Jack (I).
Confirm that the speaker is turned “ON”.
Confirm that the Speaker AC Adapter(P) is fully inserted into the wall
outlet and the power cord from the AC adapter is firmly connected to
the Speaker Power Input Jack (F).
Or
Check that the “C” cell batteries are fresh and inserted for correct
polarity (t, -).
Check that the audio source (stereo, TV, etc.) is turned on and
providing sound as it normally should.
Check that the speaker volume (D) 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 be inactive otherwise.
ri”yd Check the left/right balance control on the audio source.
Speaker
No Sound/ If using battery power, batteries may be low. Replace if necessary.
Distortion/
Static
Check that the speaker Tuning Indicator Light (A) is illuminated
green. If not, adjust the Tuning Control Wheel (B) until the light
changes from red to green.
Check that the transmitter Audio Level Indicator Light(H) is flickering
intermittently. If you are using a fixed output and the tight is on solid,
or if the light is not on at all, adjust the Output Level Control Wheel (K)
so that the light flickers intermittently.
Or
If you are using a variable output, make sure the Output Level
Control Wheel (K) is all the way right (as shown under “Adjust the
Transmitter” page 7) and adjust the volume on the audio source up or
down as necessary to make the tight flicker intermittently.
Change the position of the transmitter Frequency Control Wheel (N)
to change the operating frequency. Then, readjust the speaker
Tuning Control Wheel (B) until Tuning Indicator Light (A) changes
color to green.
Try changing the physical location of the transmitter. Locate it as
high and free of obstruction as possible. Avoid placing directly on
top of a TV, if possible.
Try moving the transmitter and speakers closer together. Sending the
signal through certain materials, such as glass, tile, and metal, can
decrease the effective transmitting distance of the system.
