CHANNEL VISION A0350 Flush Mount Amplifier
Product Information
- Product Name: Aria Flush Mount Amplifier
- Brand: CHANNEL VISIONTM
- Model: A0350
- Description: The A0350 Flush Mount Amplifier is a powerful amplifier that can be used with Channel Vision’s CAT5 audio hubs or with SP525, SP650, and SP800 Free Standing Speakers to create a high-quality amplified speaker system. It features an integrated class D amplifier, pre-amp audio outputs for easy connection to a powered subwoofer, and a local audio input to override the wireless audio signal.
Product Usage Instructions
- Connect the power supply to the “Power In” terminal at the rear of the unit. Ensure that the voltage polarity markings on the screw terminals are followed.
- If using an IR receiver, connect it to the “IR Input” terminal at the rear of the unit (optional).
- Connect the line-level audio sensing input to the “Local Audio In” terminal at the rear of the unit to override the primary wireless or CAT5 audio
- Connect the speakers to the “Speaker Outputs” terminals at the rear of the unit.
- If using in-wall speakers, connect them to the “Rear Speaker Outputs” jacks at the rear of the unit.
- If connecting a powered subwoofer or external amplifier, use the “RCA outputs” to make the connection.
- If using a CAT5 audio hub, connect its output to the “CAT5 Audio Input” at the rear of the unit.
- If using an IR control keypad, connect it to the “Keypad Input” at the rear of the unit.
- Adjust the left and right audio trim pots to control the maximum output level of the amplifier.
- Adjust the front RCA input sensitivity using the corresponding trim pot. Clockwise rotation reduces sensitivity, while counterclockwise rotation increases sensitivity.
- Set the volume jumper (J6) to pins 1&2 for default power up volume or pins 2&3 for previous volume level on power up.

A0127 ... IR repeating keypad. The A0127 contains the IR codes to operate
the volume controls in the Amplified Wireless Audio Receiver. You may also use
a standard IR receiver or a 3rd party keypad. When using a simple IR receiver,
you will need to use the A0505 remote control which contains the IR 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.
A0501, A0502, or A0505 … Remote control. Contains IR codes for
controlling the Amplified Wireless Audio Receiver as well as many other
Channel Vision audio products.
IR-2400 … Plasma-Proof IR receiver.
In-wall, In-ceiling Speakers, and Free Standing Speakers... Channel
Vision offers a full line of premium speakers. These speakers are perfect for
whole-house music or home theater applications.
A0350 Installation
The A0350 can be installed in the wall using a standard 2-gang junction box or
low-voltage mounting ring. The Flush Mount Amplifier can also be installed
into the back of Channel Vision’s SP525, SP650, or SP800 Free Standing
Speakers.
In-Wall Installation
Attach unit with the provided screws
Standard 2-gang ring or extra deep j-box (not included) Note: if using a j-box, it must have a minimum depth of 3.5”
Take care not to pinch
wires when installing into 2-gang box.
In-Speaker Installation
One Amplified Receiver can serve one pair of speakers. 
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 audio system.
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.
- Place the CAT5 between the blade and the first notch of the J-110 tool.
- Rotate the tool only once. Multiple turns could damage the inner wires.
- Inspect the inner wires for damage. If any wires are cut start over at step 1.
TIA-568A RJ-45 Modular Plug
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.
