Step 6 - Select Devices - Polycom EF2201 Application Note

manually adjusting crosspoint gains, or by re-running the InstantDesigner and
adjusting the zone matrix and re-uploading the configuration file to the Vortex
devices.
Figure 14. The reinforcement level for the microphones in Zone 2 to loudspeakers in Zone 1
is set to -18dB.
In Figure 14, the reinforcement level between adjacent zones was adjusted to
-18dB and the reinforcement level between zones two zones apart was -12dB.
These zone gains will be used to create the routing and mapping through the
Vortex matrix and bus matrices.
After the reinforcement levels have been specified, the next step is to determine
the equipment required to implement the design. If sound reinforcement was
used, this will be step 6; if sound reinforcement was not used, the next step will be
step 4.
Step 6 – Select Devices
The next step for InstantDesigner is to select the Vortex devices that are required
to implement the system. The two criteria for automatically selecting these
devices are minimum cost or minimum rack space. Minimum cost selects the
equipment with the lowest list price while minimum rack space selects the
equipment that requires the fewest rack spaces. The default method is to choose
the equipment that has the minimum cost, but there are times where the minimum
rack space selection may be preferable. For many systems, but not all, the two
results are the same.
