P-1044

4-Source/4-Zone CAT5 Audio Matrix

By

6

The P-1044 is a 4-source, 4-zone matrix switcher for Channel Vision’s
CAT5 audio system. It allows up to four different sources to be played in
four different zones simultaneously, making it perfect for families with a
variety of listening interests. Controlling your music is easy with the
P-1044’s source specific IR repeating which allows independent control
of identical source components. For example, two identical CD players
can be controlled independently.

Features:

!

LED status indicators

!

Source specific IR routing

!

Input connections: RJ-45 or RCA

!

Output connections: RJ-45 or 110 punchdown

!

Compatible with Channel Vision’s AB-124 amplified keypad

4 Zone Outputs

Allows connection of AB-124 keypads
Provides for either 110 or RJ-45 (see note under LED Indicators)

LED Indicators

Blue LED indicates that the zone is active.
Red LED indicates which connector is being used.
Note: Each zone will only support 1 keypad.
If keypads are connected to both the RJ-45 and 110 connectors, only
the keypad connected to the RJ-45 will be active and the red LED
near the RJ-45 connector will be illuminated.

Compatibility

The P-1044 adheres to the same protocols as Channel Vision’s other CAT5
audio hubs to ensure maximum compatibility. However, some amplified
keypads (such as the AB-114) will not provide control of source selection. If
the keypad provides IR pass through (as does the AB-114), you can use an
A0501 remote control to make source selections. For best results we
recommend using the AB-124 amplified keypad.

How it Works

The P-1044 is a matrix switcher for Channel Vision’s CAT5 audio system. Any
zone can independently select and listen to any source at any time. Source
selection can be done either from an AB-124 amplified keypad or by using the
A0501 remote control. For details on the A0501 remote control, please refer to
the section of this manual titled “Using the A0501 Remote Control.” The basic
operation of the AB-124 is described below.

Using the AB-124 Amplified keypad...

The Pwr (power) button located at the lower left of the keypad is also used for
source selection. When the AB-124 is powered on, press and release the
power button to scroll through the input sources. As you change sources,
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).

Basic Application

A basic system can be created with four amplified keypads (model AB-124)
and four pairs of speakers. The source components can be controlled by
pointing their remote control at the IR sensor in the AB-124 keypad.

Expanding The System

Larger systems consisting of more than 4 zones can be created by
adding a second P-1044. Use RCA ‘Y’ connectors to split the audio
sources into both units. Use the provided ribbon cable to connect the
“Link” terminals. This will allow IR signals received through one P-1044 to
be transmitted to the other P-1044.

The P-1044 can accept signals from either a standard analog audio
output (via RCA inputs) or a CAT5 audio output from one of Channel
Vision’s CAT5 audio input modules.

Many different components can be integrated together. The system below
integrates a single-source CAT5 audio hub (model P-1014) as well as
telephone paging modules. The keypads connected to the P-1014 will act
as sub-zones to the P-1044. These sub-zones will all play the same audio
which is perfect for common areas such as hallways, bathrooms, kitchen,
or dinning room. Adding the C-0920 and P-0925 allows paging to occur
in these common areas.

Connection Tips and Troubleshooting

1) Be sure you have connected the CAT5 cable correctly. Note that the
stripe/solid pattern should match the labels on the product. Miss­wiring 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) Be sure IR emitters are directly over the IR sensor for all devices you
wish to control.

4) If no audio is heard in a zone... inspect the status LEDs for that zone.
The red LED next to the output you are using should be illuminated
and so should the blue LED labeled “Active”. Note that there are two
red LEDs for each zone output, one for RJ-45 connector and one for
the 110 connector. These red LEDs indicate which output connector
is being used (only one can be used at a time). If you connect
keypads to both of these connectors simultaneously, only the RJ-45
output will be activated.

5) If no audio is heard and the blue LED labeled “Active” is not lit...
Make sure that audio is playing (it must be playing for the Active light
to come on). If music is playing, re-issue the source command (i.e.
re-select the source using the remote or keypad).

6) If a CAT5 wire is connected to the P-1044, make sure the other end is
terminated with a keypad. If the CAT5 wire is left un-terminated while
the other end is attached to the P-1044, it may be possible for the
conductors in the rough end of the CAT5 to short together and cause
problems for the system.

7) If one of the source inputs is not working try connecting that source

into one of the working source inputs. If the problem persists check
the cabling between the source and the P-1044.

10

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 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.
