The amount of reinforcement of the "Wireless Mic" channel to the zone 1 amplifier can be increased and
decreased, respectively, by 1dB with the following commands.

dec matrix_gain "Wireless Mic" "Amplifier 1" 1
It is also possible to set user minimum and maximum values for the crosspoint levels to prevent adding too
much gain for reinforcement. The maximum crosspoint gain settings can be set to -3dB for the wireless
microphone to zone 1 amplifier with the following command.
set matrix_gain max "Wireless Mic" "Amplifier 1" -3
When the volume of the crosspoint is raised, the value will not become larger than -3dB.
The remote audio being played into all the zones can be controlled by using the "RemoteAudio" submix. In
room volume may be increased with the following volume command.

Creating a Sixteen Microphones with Six-Zone Sound
Reinforcement Conferencing System
This example shows how to use the sound reinforcement and conferencing processing to create an audio
conferencing solution that includes a lectern microphone, wireless microphone, and sixteen tabletop
microphones that are reinforced into the room. This example includes sixteen table microphones, a lectern
microphone, a wireless microphone, stereo program audio, a single telephony interface, and six zones of
audio amplifiers for reinforcement.
The layout for this style of room can be seen in the following figure along with the zone definitions. In this
room, the lectern microphone will be reinforced into zones 2-6, the wireless microphone reinforced into
