The WA-350 Point-To-Point Amplified Wireless Audio Receiver and WA-351

1-To-Unlimited Amplified Wireless Audio Receiver work with Channel

Vision’s WA-320 and WA-321 to create distributed audio systems without

the need for running wires from one room to another. The integrated

100Watt amplifier is ideal for powering distributed audio speakers as well as

wireless home theater applications.

Features:

!Receive wireless audio from up to 300ft. away

!100Watt integrated class D amplifier

!Pre-amp audio outputs for easy connection to powered subwoofer

!Local audio input to override the wireless audio signal

!Input for compatibility with Channel Vision’s CAT5 audio systems

!Easy installation and linking

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.

codes to control the WA-350, WA-351, and A0350. IR codes

can be downloaded from www.channelvision.com, or learned

from an A0505 remote control.

Using the WA-320 & WA-350 in a Home Theater

The WA-320 can accept the 5.1 outputs from a home theater amplifier and

transmit the signal to several WA-350 Wireless Audio Receivers. The WA-350’s

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.

Note: This equipment has been tested and found to comply with the limits for a

Class B digital device, pursuant to part 15 of the FCC Rules. These limits are

designed to provide reasonable protection against harmful interference in a

residential installation. This equipment generates, uses and can radiate radio

frequency energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communications. However,

there is no guarantee that interference will not occur in a particular installation. If

this equipment does cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one or more of the following

measures:

!Reorient or relocate the receiving antenna.

!Increase the separation between the equipment and receiver.

!Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

!Consult the dealer or an experienced radio/TV technician for help.

!Modifications not expressly approved by the manufacturer could void the

user's authority to operated the equipment under FCC rules.

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 audio-

sensing” 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.
