Step 3 – Sound Reinforcement Zones
The next step for InstantDesigner is to determine whether to use sound
reinforcement zones as shown in Figure 9. Sound reinforcement allows the
designer to create loudspeaker zones, place microphones into these zones, and
control the amount of reinforcement of the microphones into neighboring
loudspeaker zones. Microphones that are placed in a loudspeaker zone are NOT
reinforced into the same loudspeaker zone – the microphones will only be
reinforced into other loudspeaker zones.
Answering No to question posed in Step 3 will move the designer to the next step
in the process, Select Devices. This step is described in the section entitled Step 6
– Select Devices.
Answering Yes to the question posed in Step 3 will show the screen in Figure 10,
emphasizing that microphones from one loudspeaker zone will be reinforced into
other loudspeaker zones with the blue microphone audio and green microphone
audio indicating different loudspeaker zones. Answering Yes also increases the
number of steps in the process from 6 to 9 as additional information is required to
properly configure the loudspeaker zones (see Figure 3).
