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.
