Compatibility
The AB-1 adheres
Vision’s other CAT5 audio hubs to ensure maximum
compatibility. Single-source CAT5 audio products from
other manufacturers may not (and typically will not) use the
same control codes for the AB-135 keypad.

Channel Vision’s
How it Works
The AB-1 can be used to control a single source with a CAT5 audio hub. T
provides basic controls: volume up, volume down, and power on/off.

Basic Operation
Using the AB-135 Amplified keypad...
The Pwr (power) button located at the lower left of the keypad is used to turn the unit
on or off. Press and hold the power button to turn the keypad off.
After volume is changed, the LEDs will stay lit for 5 seconds, showing the current
volume level. Volume adjustments can be made using the up/down buttons to the
right hand side of the keypad.

Model AB-303
The AB-303 A-BUS Bluetooth local input module provides a local wireless input
connection for the purpose of streaming audio from sources such as smart-phones,
tablets and computers, etc with Bluetooth capability to individual A-BUS equipped
rooms. When the AB-303 is paired, it will automatically switch the music source from
the main audio source to the local Bluetooth source. This local connection will remain
until pairing is disconnected, or the Bluetooth device is out of range.
If pairing remains selected on the Bluetooth device, when it comes back into range,
the connection will automatically reconnect and play audio in the zone.
Features:
Adds Bluetooth streaming capability to existing or new A-BUS systems

Functions as a main or local source

Operation:
To pair to the AB-303, consult instructions on pairing supplied with your Bluetooth
device. The Bluetooth LIM identification code will have the prefix AB in front of the
individual code number. When pairing occurs, a blue LED will light up on the front
plate. For systems with multiple AB-303s, it is recommended the codes be changed
to easily identify each room before completing installation.
Operating Range:
Bluetooth devices are intended to provide wireless communication between
enabled devices within a room. In ideal conditions, range can be up to 50’
This distance can be reduced significantly by transmission interference from other
communication devices, electrical wiring and room construction materials, such as
brick walls and concrete floors. When the AB-303 is operating near maximum range,
the signal may intermittently drop in and out, as signal strength varies.
Bluetooth Source Volume Level Compatibility:
The audio output level from Bluetooth enabled devices can vary from brand to brand.
Though the AB-303 has been adjusted to be equal to the output of most Bluetooth
devices, in some cases the level may be different. Most devices have their own
adjustable volume level, and it is recommended that this be used to adjust the output
level to match the main audio source’s volume level.
Room Identification:
Pairing each AB-303 requires the identification of an individual code number
beginning with the prefix AB (ABxxx). This code number can be replaced with an
individual room name identification such as Bedroom 1, Study, Patio, etc. prior to
installation. To download the renaming software visit www.a-bus.com/bt. Once
downloaded and installed, connect the AB-303 via the mini USB socket located at
the side of the unit to your PC and start the program, follow the on screen prompts to
rename the device.

Model AB-203
AB-203 Single Source & Main Module. One per system; Connects sources to the
system; Mount the unit near audio components (CD player, receiver, etc.). This device
is designed for your main audio source. Plug the AB-303 to the system/explansion
input of this device, and plug the AB-135W on the system/A-Bus output of this device.
Plug the 24vDC power supply into the power connector.
Warning: Do not adjust the volume all the way up if no audio is present.
Doing so could damage your speakers if audio reconnects.

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.
Possible 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: RCA Audio input is not working.
Troubleshooting: Verify source audio is playing, or try another audio source Check speaker
wires to verify nothing is backwards or crossed.
Possible Cause: There is no signal (or very weak signal) coming from the source, or source is
not compatible with AB-203.
Solution: Make sure the source audio is playing. Try a different source.
Problem: CAT5 audio input (AB-303) is not working.
Troubleshooting: Verify you have plugged the CAT5 output on the AB-303
into the input on the front of the AB-203. Verify you have plugged the system
output of the AB-203 into the input on the back of the AB-135.
Possible Cause: AB-303 not connected properly, wire crimped improperly or plugged into the
wrong terminal.
Solution: Verify wiring, verify RJ-45 crimps
Problem:
Troubleshooting:
1. Restart Bluetooth source device
2. Check Source device is connected to Wifi
3. Check the music source is active before pairing
4. The blue LED indicates when devices are paired
5. Try a different A-BUS source.
6. Make sure Bluetooth device is in play mode
Problem:
Troubleshooting: Verify you have connected the CAT5 cable correctly. Follow the TIA-568A
standard at both ends. Mis-wiring can cause distorted sound, prevent the system from
functioning, or possibly cause damage to the components in the system. Verify you have
connected the speakers in phase. Follow the label on the product. Out of phase speakers can
rob the system of its bass, especially when driving dual-voice-coil speakers.
If no audio is heard, check to make sure that the audio source is playing, then press the power
button on the AB-135 to make sure it is turned on.
Not linking with Bluetooth device or Linking with no audio is present.
