Linking the WA-350 to the WA-320
The WA-350 and WA-320 operate on a 1-to-1 basis and therefore they must be
“Linked” to each other prior to the first use. Once linked they will maintain their
paired status even if a power loss occurs. The “RST” button can be used to
reset and separate a linked pair.
Make sure audio is playing into
the WA-320.
Press and hold the Link button
for 3 seconds to begin the linking
process.
The green PWR/LINK LED will
turn orange.
If you encounter interference,
press the link button on the
WA-320 to skip to a different
broadcast channel.
Press the link button on the
receiver within 6 seconds to
complete the process.
Note: The green LINK LED
will blink until the receiver
has been linked.

Using the WA-321 & WA-351 in a Home Theater
The WA-321 can accept the left/right surround speaker outputs from a home
theater amplifier and transmit the signal to the WA-351. The WA-351 can then
amplify the signal and power the speakers. The volume level of the surround
speakers will be raised and lowered by the volume control of the home theater
amplifier.

Using the WA-321 & WA-351 for Distributed Audio
These wireless audio products make it easy to transmit audio from one room
to another. Connect any standard audio component to the input connectors
of the WA-321 in Room 1 which will broadcast the signal to the WA-351 in
other rooms of the home. The A0127 can be connected to the rear panel of
the WA-351 to allow volume control of the WA-351 amplifier. If a powered
subwoofer is connected to the rear panel of the WA-351, its volume will be
controlled by the A0127.

Troubleshooting:
Problem: Hum in System
Troubleshooting: Plug all parts of the system into the same outlet to see if
the hum goes away.
Cause: The different components in the system are connected to different
electrical grounds. This forces electrical currents to find alternate paths to
ground causing an audible 60Hz hum.
Solution: Plug products into an electrical circuit with a common ground. Lift
the ground with a ground lifting plug.
Problem: Transmitter is not linking with the receiver.
Troubleshooting: Make sure you are linking compatible models (WA-320
with WA-360). Check if pwr/lnk LED indicator on the transmitter is turning
amber and that the signal LED is lit.
Cause: Link button on WA-350 is not being pressed quickly enough. Review
the linking procedure in this manual. Please note that a transmitter and
receiver will remain paired even after being unplugged. This allows you to
complete the linking process before placing the receiver in it’s final location.
Solution: Press the Link button on the WA-320 and confirm that the pwr/lnk
LED turns amber. Within 6 seconds, press the Link button on the WA-350.
Problem: Can’t link to the transmitter, or audio is cutting out.
Troubleshooting: Check the source, is it sending a signal? Consider setting
the jumpers on the transmitter (WA-320/WA-321) to the “disable audiosensing” position during setup procedure (see the Rear Panel Features and
Connections section). This will ensure that the transmitter will not mute
during pauses or very quiet passages.
Cause: Either there is no audio going into the transmitter, or the audio is very
quiet which is causing the transmitter to mute.
Solution: Use a known good audio source. If you can’t find any other
problems, try using a different source component even if you think your audio
source is OK.
