Orbis – Quick Start Guide

Connection of microphone units without redundancy
• The microphone units/system units are connected in one or two lines to the control unit. As cables
use standard CAT5e cables (S/UTP, min. AWG 26 diameter or better). The audio transmission,
power supply and control is made via one cable.
• At maximum you can connect 50 microphone units/system units per line so that a total of 100
microphone units is available.
Note: The max. number of microphone units also depends upon the cable type and cable length so
that the actual number of microphone units to be operated might be less than 50 or 100.
CAUTION: When using this kind of connection, there is no redundancy, i.e. if one microphone
unit/system unit fails, the whole line fails after the interruption, but the microphone units/system
units will still work before the interruption.
