Instruction manual

1) Be sure you have connected the CAT5 cable correctly. Follow the TIA-
568A standard at both ends. Mis-wiring can cause distorted sound or
prevent the system from working at all!
2) Be sure 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.
3) Trouble with IR control?
a. Make sure you are using the correct remote control. The AB-124
will respond to IR signals from the A0501 and the AB-500 remotes
produced by Channel Vision. The A0501 can provide both volume
control and source selection commands, but the AB-500 is only
pre-programmed with the volume control commands. Other 3rd
party remote controls that are capable of learning the IR codes
from the A0501 can also be used.
b. The top LED on the AB-124 acts as an IR receiver feedback LED
that flashes whenever IR signals are received. Check to make
sure the LED flashes whenever you press buttons on your remote
control. If you don’t see the feedback LED, try replacing the
batteries in your remote control.
c. Make sure your IR emitters are placed directly over the sensor on
the device you are trying to control.
4) If no audio is heard, check to make sure that the audio source is
playing, then press the power button on the AB-124 to make sure it is
turned on.
a. Note, if the status jumper is on pins 1 & 2, the AB-124 will turn off if
there is no audio present for more than 2 minutes. For most
applications, it will be desirable to place the status jumper on pins 2
& 3 so that the AB-124 will revert back to its previous condition
(either on or off) when music is played after a long pause.
b. There may be something wrong with the CAT5 audio hub. Some
Channel Vision audio hubs provide LED indicators to show which
zones are connected and active. Review these LEDs and refer to
the instruction manual for your specific audio hub.
5) Observe wiring distance specifications. The maximum recommended
wire length between the audio hub output and AB-124 is 150 feet.
Although the AB-124 can work at greater distances, such extreme
distances are not recommended because erratic performance may
result due to the power loss caused by the CAT5 wire.
6) If you need additional help troubleshooting the AB-124 please contact
Channel Vision technical support (1-800-840-0288) or check our

Stripping and Connecting CAT5 Wire
Blade
Cat5
1. Place the CAT5 between the blade and the first notch of the J-110 tool.
CAT5 cable should be stripped with a proper stripping tool, such as Channel
Vision’s J-110 tool.

Rotate
1 turn only
2. Rotate the tool only once. Multiple
turns will cause you to cut into the
inner wires.
3. Inspect the inner wires for damage.
If any wires are cut start over at step 1.
