Using the A0350 Behind a TV
The A0350 can be flush-mounted behind a wall-mounted TV to power in-wall
speakers. By connecting the audio outputs from the TV to the RCA inputs of
the A0350, the TV’s audio signal will be amplified to the in-wall speakers. If the
TV has variable audio outputs, the sound level will simply be controlled by the
TV’s volume buttons. If the TV only offers a fixed audio output, A0350 volume
level can be adjusted by connecting an IR-2400 and using a compatible
remote such as model A0505. The RCA audio outputs on the back of the
A0350 can be connected to a powered subwoofer to add more bass to your
audio system.

Using the A0350 in a Stand-alone System
The A0350 can be flush-mounted in a room to power in-wall speakers. By
connecting the audio outputs from an audio source to the RCA inputs of the
A0350, the audio signal will be amplified to the in-wall speakers. Most audio
sources only offer a fixed audio output, A0350 volume level can be adjusted by
using an A0127 keypad or by connecting an IR-2400 and using a compatible
remote such as model A0505. The RCA audio outputs on the back of the
A0350 can be connected to a powered subwoofer to add more bass to your

Using the A0350 with a CAT5 Audio Hub
The A0350 can accept the signal from one Channel Vision’s CAT5 Audio Hubs,
such as the P-2044. Audio and IR signals are transmitted through the CAT5
cable, while power is connected directly to the front of the A0350. Alternatively,
power can be connected via a pair of 16AWG wires to the power screw
terminals on the back side of the A0350.

Using the A0350 with a CAT5 Audio Hub - Alternate Setup
The A0350 can accept the signal from one Channel Vision’s CAT5 Audio Hubs,
such as the P-2044. An A0125 keypad can be wired in the CAT5 line along
with other input modules to accommodate a more traditional CAT5 Audio
wiring scheme. If an additional 2-conductor 16 AWG wire is run between the
A0350 and main equipment location, the A0350 power supply can be remotely
located and connected via the rear-panel screw terminals.

Stripping and Connecting CAT5 Wire
CAT5 cable should be stripped with a proper stripping tool, such as Channel
Vision’s J-110 tool.
1. Place the CAT5 between the blade and the first notch of the J-110 tool.
CAT5
Blade
2. Rotate the tool only once. Multiple
turns could damage the inner wires.
3. Inspect the inner wires for damage.
If any wires are cut start over at step 1.

Troubleshooting:
Problem: Hum in System
Troubleshooting: Plug all parts of the system into the same outlet to see if
the hum goes away. Try lifting the ground with a ground lifting plug.
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.
Problem: CAT5 Audio input is not working.
Troubleshooting: Make sure there is a strong and constant signal coming
from the CAT5 Audio Hub. Make sure audio signals are NOT connected to
the front RCA jacks (these signals will override the CAT5 input). Make sure
jumper J17 and J18 are on pins 1&2. Check if “Active” LED indicator on the
front panel is lit.
Cause: There is no signal (or very weak signal) coming from the source.
There is a source connected to the front RCA jacks that is overriding the
CAT5 input. Jumpers J17 and J18 are on the wrong pins causing the CAT5
audio input to be disabled.
Solution: Remove or turn off any audio source connected to the front RCA
jacks. Set jumpers J17 and J18 to pins 1&2. Make sure the source audio is
playing.
