12.5Repetition 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

4Jc Repetition menu item.

Note

When you increase the repetition rate, the audio delay is increased.

12.6Audio 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).

12.6.2 Recorder

In the Recorder mode, audio output 2 of the central control unit transmits a signal that you can connect to an external audio recorder (refer to figure 12.1). The central control unit has no effect on the volume level of the signal.

In the Recorder mode, the signal on audio input 2 of the central control unit is added to the floor signal.
