The WA-321 1-to-Many Wireless Audio Transmitter and WA-361 1-to-Many
Wireless Audio Receiver make it possible to create a distributed audio
system without running wires from one room to another. The WA-321 can
accept either line level or speaker level audio, making it easy to distribute
signals to the rear speakers of a surround sound system. The transmitter
can link to multiple receivers allowing music to be distributed to multiple
locations simultaneously. To avoid interference, the WA-321 can broadcast
over 8 different transmission channels.
Features:
!Wirelessly transmits audio up to 300ft.
!Line-level, Speaker-level, or CAT-5 Audio System inputs (WA-321)
!Standard Line-level audio outputs (WA-361)
!8 transmission channels
!Easy installation and linking

A0240... 2-channel 40 Watt amplifier. It can be
used to power a small 1-room audio system or
integrated with Channel Vision’s A0302 to
provide supplemental power to low power
distributed audio systems.
In-wall and In-ceiling Speakers... Channel
Vision offers a full line of premium in-wall and
in-ceiling speakers. These speakers are
perfect for whole-house music or home theater
applications.
VC-302... Impedance Matching Volume Control
The VC-302 is an impedance matching volume
control with an IR receiver knockout. The
knockout allows Channel Vision’s
IR-2400 to be integrated with the volume
control for applications that require IR
repeating. The VC-302 comes with white,
ivory, and almond knobs and face plates to
easily match other wall plates in the room.
Linking the WA-361 to the WA-321
The WA-361 and WA-321 operate on a 1-to-Many broadcast basis. The WA-361
must be “Linked” to a specific WA-321 transmitter 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 release a linked receiver from its transmitter.
Press and hold the Link button for 3 seconds
to begin the linking process
.
The green PWR/LINK LED will turn orange.
Press the link button on the receiver within 6
seconds to complete the process.
Note: The green PWR/LINK LED will blink
until the receiver has been linked.

Using the WA-321 & WA-361 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-361. The WA-361 can then
output the signal to a small amplifier like the A0240 which powers 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-361 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, and use the RCA outputs of WA-361 receivers to feed
amplifiers in several different rooms. If a fixed gain amplifier is used (such as
the A0240), a volume control like the VC-302 will be needed to adjust the
volume level in the remote rooms.
