Introduction

Using extra loudspeakers and local reinforcement

When using the video system with local reinforcement, extra
loudspeakers are strongly recommended to ensure that people in
the room get a good auditory experience.

Configuration example
The configuration example describes a setup with the main loudspeakers on
Line Output 1 and 2, the extra loudspeakers on Line Output 3 and 4, and local
presenters' microphones on Microphone Input 1 and 2.
Sign in to the web interface and navigate to
settings referred below.
1. Set the delay (ms) for the extra loudspeakers:
Audio > Output > Line 3 > Delay > DelayMs
Audio > Output > Line 4 > Delay > DelayMs
The delay can vary based on where in the room the loudspeakers are
placed. To calculate the delay, see the Using Extra Loudspeakers and Local
Reinforcement guide.
2. Switch on reinforcement for the microphones that the local presenters will
use:
Audio > MicrophoneReinforcement > Input > Microphone 1 Mode
Audio > MicrophoneReinforcement > Input > Microphone 2 Mode
3. Switch on reinforcement for the extra loudspeakers:
Audio > MicrophoneReinforcement > Output > Line 3 > Mode
Audio > MicrophoneReinforcement > Output > Line 4 > Mode
4. Set the amplification of the microphone signal from the local presenters to
the extra loudspeakers:
Audio > MicrophoneReinforcement > Gain
Adjust the gain in small steps and make sure that the final setting is well
below the feeding level.

We recommend reading the Using Extra Loudspeakers and Local
Reinforcement guide for a comprehensive description and best practices for
the solution.
