With MX700, MX800 Single and MX800 Dual extra loudspeakers 
are required to enable local reinforcement functionality.
Configuration example 
The configuration example describes a setup with the integrated loudspeakers 
(HDMI) as main loudspeakers, the extra loudspeakers on Line Output 1 and 2, 
and local presenters’ microphones on Microphone Input 1 and 2. 
Sign in to the web interface and navigate to 
Setup > Configuration
, to find the 
settings referred below.
1.  Set the delay (ms) for the extra loudspeakers:
Audio > Output > Line 1 > Delay > DelayMs 
: <0..290>
Audio > Output > Line 2 > Delay > DelayMs 
: <0..290>
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 
On
Audio > MicrophoneReinforcement > Input > Microphone 2 Mode 
On
3.  Switch on reinforcement for the extra loudspeakers:
Audio > MicrophoneReinforcement > Output > Line 1 > Mode 
On
Audio > MicrophoneReinforcement > Output > Line 2 > Mode 
On
4.  Set the amplification of the microphone signal from the local presenters to 
the extra loudspeakers:
Audio > MicrophoneReinforcement > Gain 
: <-54..15>
Adjust the gain in small steps and make sure that the final setting is well 
below the feeding level.
Additional resources
We recommend reading the Using Extra Loudspeakers and Local 
Reinforcement guide for a comprehensive description and best practices for 
the solution.
