2.2.5 Step 5 – Determine the E4
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 E4 system outputs. Area 2 uses one standard volume control requiring one E4 output channel.
Areas 4 and 5 share a common volume control and can be combined on a third E4 output channel. Since only four
outputs are required and the total combined power requirement is less than 400W, only one E4 unit would be
needed for this system.

determine the quantity of E4s we will need.
