Repetition rate

When other wireless networks cause interference, the
audio quality can decrease. In some cases, you can
increase the repetition rate of the audio packets to
improve the audio quality. You can change the
repetition rate of the audio packets with the
4Kc Repetition menu item.
Note
When you increase the repetition rate, the audio
delay is increased.

Audio routing modes

12.6.1 Introduction
You can set the audio routing mode of the system with
the 4E Routing I/O 2 menu item. The functions of audio
input 1 and audio output 1 of the central control unit are
the same in each audio routing mode. The signal on
audio input 1 is always added to the floor signal. The
signal on audio output 1 is always suitable to connect
the system to an external public address system (for
example, Praesideo).
