Audio over CAT5 (MOCAT)

The highly successful MOCAT has been designed to simplify and speed up installations where multiple microphone inputs or line level inputs need to be situated a distance from the amplifier equipment.
Types of installation include churches, schools, theaters and corporate boardrooms.

MOCAT is an extremely versatile and cost effective installation device that removes the need for multiple cable runs from remote audio inputs to the amplifier equipment.
The MOCAT can transmit up to four microphone or line level signals down one screened cat5e cable for up to 1000 metres. This is reduced to 3 channels if using unscreened cat5e cable.

Each input and output can be independently configured for balanced or unbalanced signals as well as line level or microphone level.
There is also an option to provide phantom power to the microphone inputs independently.
Each unit fits neatly into a standard UK double back box and only requires a power supply at the output or amplifier end (PSU supplied as part of system).

Cat5 terminations Screw terminals
Protected against short circuit on CAT5 cable to ground.

Please Note:
When using Cat5UTP (unshielded cable, the Mocat system is only capable of transferring up to 3 Channels.
STP(shielded) Cat5 cable will allow for the maximum 4 channels.
