CHANNEL VISION P-2044 Audio System Matrix Instructions

CHANNEL VISION P-2044 Audio System Matrix

Product Information

The Channel Vision Model P-2044 is a 4-source, 4-zone CAT5 Audio Matrix switcher. It allows up to four different sources to be played in four different zones simultaneously, making it ideal for households with diverse listening interests. The P-2044 features LED status indicators, source- specific IR routing, and input/outputconnections via RJ-45 or RCA. It is compatible with Channel Vision’s A0125 keypad for easy control.

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 A0125 keypad

Product Usage Instructions

The P-2044 allows independent control of identical source components.
To control your music, follow these steps:

1. Connect your audio sources to the appropriate inputs using RCA or RJ-45 connectors.
2. Connect the A0125 keypads to the desired zones using either RJ-45 or 110 connectors. Note that each zone can only support one keypad.
3. Power the P-2044 by connecting the power supply to the power connector.
4. To expand the system, use the Link In/Link Out feature to transfer IR signals to multiple units.
5. To select and listen to a source in a specific zone:
   • If using the A0125 Volume Control Keypad, press the Pwr (power) button to scroll through the input sources. The top 4 LEDs on the keypad will illuminate corresponding to the selected source.
   • After selecting a source, the LED will stay lit for 5 seconds before returning to display the current volume level.
   • Adjust the volume using the up/down buttons on the right-hand side of the keypad.
6. If you have the A0505 remote control, refer to the manual section titled “Using the A0505 Remote Control” for more details on controlling the keypad

How it Works

The P-2044 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 A0125 volume control keypad or by using the A0501, A0502, or A0505 remote controls. For details on the A0505 remote control, please refer to the section of this manual titled “Using the A0505 Remote Control.” The basic operation of the A0125 is described below. Using the A0125 Volume Control Keypad…The Pwr (power) button located at the lower left of the keypad is also used for source selection. When the A0125 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 A0505 remote control (see the section titled: Using the A0505 remote control for more details ).

Basic Application

A basic system can be created with four volume control keypads (model A0125), four pairs of speakers, four A0240 amplifiers, and four A0302 speaker to line- level interface modules. The source components can be controlled by pointing their remote control at the IR sensor in the A0125 keypad.

Expanding The System

Larger systems consisting of more than 4 zones can be created by adding a second P-2044. 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 I signals received through one P-2044 to be transmitted to the other P-2044.

Using Different Input Devices

The P-2044 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.

Creating Sub-Zones

The single-source CAT5 audio hub (model P-2014 can be integrated together with the multi-source CAT5 audio matrix (model P-2044). The kevpads connected to the P-2014 will act as sub-zones to the P-2044. These sub-zones will all play the same audio which is perfect for common areas such as hallways, bathrooms, kitchen, or dinning room. For this kind of custem all of the A0125 kevnads should be confiaured for multi-mode.

Using the A0505 Remote Control

Using the A0505 remote control… The A0505 is designed to allow you to control your P-2044 without having to touch the buttons on the A0125. Simply point the A0505 remote control at the IR sensor located at the bottom of the A0125 and press the desired button.

Mounting Options

The P-2044 can also be mounted in a standard structured wiring enclosure or screwed to a wall or flat surface as shown below.

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. Miss-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. 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 connectoris 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-2044, 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-2044, 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-2044.

Stripping and Connecting CAT5 Wire

CAT5 cable should be stripped with a proper stripping tool, such as Channe Vision’s J-110 tool.

1. Place the CAT5 between the blade and the first notch of the J-110 tool.
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.
