2.0 Designing with the E-4 System

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.

Now we can take a look at how the maps we created can help us

determine the quantity of E-4s we will need.

Total System Power = 250W

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.
