Compatibility

The AB-124 adheres to the same protocols as Channel Vision’s other CAT5
audio hubs to ensure maximum compatibility. However, when using the AB­124 in a multi-source system, we recommend using Channel Vision’s multi­source CAT5 audio matrix (model P-1044). Multi-source CAT5 audio products
from other manufacturers may not (and typically will not) use the same control
codes for advanced features such as source selection.

How it Works

The AB-124 can be used in two different modes: 1) single source mode, 2)
multi-source mode. Mode selection is controlled by a jumper setting prior to
installation. When using the AB-124 with a single-source CAT5 audio hub, it
should be set for the single-source mode. In this mode, the unit provides basic
controls: volume up, volume down, and power on/off. When using it with a
multi-source CAT5 aduio matrix, it should be set for multi-source mode. In this
mode, any zone can independently select and listen to any source at any time.
Source selection can be done either from the AB-124 amplified keypad or by
using the A0501 remote control.

Basic Operation

Using the AB-124 Amplified keypad...

The Pwr (power) button located at the lower left of the keypad is used for
source selection and to turn the unit on or off. When in single-source mode,
press and release the Pwr button to toggle the keypad on or off. When in
multi-source mode, if the keypad is off, press and release Pwr to turn it on.
Press Pwr again to see the current source selection and press repeatedly to
scroll through the 4 sources. Press and hold the power button to turn the
keypad off. While the keypad is off, press and hold the power button again to
turn off the zone output of the P-1044.

As you change sources when in multi-mode, you’ll notice that the top 4 LEDs
illuminate corresponding to the source you have selected. When source one
is selected, the first LED is illuminated, when source two is selected, the
second LED is illuminated, and so on.

After a source is selected the LED will stay lit for 5
seconds, then it will return to showing the current
volume level.
Volume adjustments can be made using the
up/down buttons to the right hand side of the
keypad. The keypad can be controlled from the
A0501 remote control (see the section titled: Using
the A0501 remote control for more details).

Jumper Settings

Jumper settings determine how the AB-124 will react under various
circumstances. These jumpers should be set to the desired configuration

before the AB-124 is installed. If you need to make changes to the jumper
settings, the AB-124 MUST BE DISCONNECTED from the system first.

Jumper setting functions explained:
Volume Preset - This jumper determines how loud the keypad will be

when it is turned on. If the jumper is on pins 1 & 2, the volume will always
be set at the default level when the AB-124 is turned on. If the jumper is
on pins 2 & 3, the volume will be at the same level as it was before the
AB-124 was turned off.

Status is active when the zone is on and audio is present. Status will go
dormant when audio is not present.

Status Active - This jumper determines what happens when the status
becomes active. Typically, when status becomes dormant, Channel Vision

amplified keypads go into a ‘sleep’ mode which mutes the amplified

keypad. If the jumper is on pins 1 & 2 when status becomes active, the
AB-124 will remain off until the power button is pressed. If the jumper is
on pins 2 & 3 when the status becomes active, the AB-124 will return to its
previous state (either on or off).

Source Mode - This jumper determines if the AB-124 will be used as a
multi-source keypad or a single-source keypad. If you are using the
keypad in a single source system, set the jumper on pins 1 & 2. If you are
using the keypad in a multi-source system, set the jumper on pins 2 & 3.
