Installation Guide

Introduction

The MonoPro™ XLR (500025, 500026) allows a standard AES analog or digital
audio channel to be connected via Cat5 unshielded twisted pair cable (UTP) in the
professional audio environment. The product features heavy duty cable strain relief
for rugged environments such as rental and staging and is available with male or
female locking XLR3 connectors for added cabling versatility.

Installation

To install the MonoPro XLR, perform the following steps:

1. The MonoPro™ XLR works in pairs. Depending on the number of audio
signals to be transmitted, use one pair of MonoPro XLR adapters for each
audio signal. For example; mono audio – two (2) adapters, stereo audio - four
(4) adapters, etc.

2. Identify the pin configuration of the adapter. One twisted pair is required for
each audio connection with an optional connection for shield. MonoPro™ XLR
is polarity sensitive. Therefore, please ensure straight-through polarity.

3. Remove the adapter cover by inserting a screwdriver at the lower edge of the
cover.

4. Loosen the cable strain relief nut and feed the Cat5 cable through the opening
into the adapter.

5. Strip back about 1” of the cable jacket and expose about ¼” of copper wire at
the end of the appropriate wires.

6. Connect the UTP wires to the screw terminal blocks, respecting the wiring
polarity. If STP is used, connect the drain wire to the Ground terminal.

7. Tighten the cable strain relief nut at the end of the adapter.

8. Plug the MonoPro™ XLR into the XLR3 connector of the audio source
equipment.

9. Repeat steps 4 to 6 for the MonoPro XLR at the receiver side.

10. Plug the second MonoPro™ XLR into the XLR3 connector of the audio
receiver equipment at the remote side.

11. Complete the connection between the two adapters, using standard UTP cable,
connector blocks and modular wall outlets as required. The following diagram
shows a typical connection.

12. Power-on the audio equipment and check the audio quality. The audio should
