2.2.5 Step 5 – Determine the E-4
requirements
Once you have identified the areas that use Auto Volume and
unique loudspeakers, you can combine different areas based on
the types of sources and controls they are using.

By combining the maps you can easily combine sources, speaker types, and control types. The information placed
in this table suggests that Area 1 and Area 3 need to be grouped separately because they are Auto Volume zones
requiring separate E-4 system outputs. Area 2 uses one standard volume control requiring one E-4 output channel.
Areas 4 and 5 share a common volume control and can be combined on a third E-4 output channel. Since only four
outputs are required and the total combined power requirement is less than 400W, only one E-4 unit would be
needed for this system.

Now we can take a look at how the maps we created can help us
determine the quantity of E-4s we will need.
