This chart indicates the

typical Ambient Noise

Level and environments

appropriate for various

speaker types.

• Find the row which is equal

to or greater than the total

number of Current Units

needed for the equipment

on the cable run.

• Find where this row crosses

the column for the wire

gauge that will be used for

the run.

• The number in the cell where

these cross is the maximum

cable length for that run.

Example: When 37 Current Units

are to be used on a 24-Gauge Wire,

the maximum usable cable length

will be 88 feet.

Note: It may be necessary to

increase the wire size (smaller

gauge numbers) or split the

speaker runs to shorten the

wire run lengths if they exceed

the chart maximums.

Connecting wire pairs together, in

parallel in a cable, effectively reduces

the gauge and lowers resistance.

The

chart below shows how the

gauge

decreases with paralleled pairs.
