(3) Current Requirements

All power amplifiers require sufficient current for proper operation and the

amplifiers designed into Apogee powered loudspeakers are no exception.

Chart #1 shows the required current for one APL-10 or APL-12 at three

standard international working voltages (120, 240, & 100V AC). Because cur-

rent drain is ultimately a function of the program source, Chart #1 shows

both the theoretical maximum, and what can be expected under typical high-

level program conditions:

We recommend powering no more than one APL-10 or one APL-12 from a

single 20A, 120V AC circuit, and no more than two APL-10 or APL-12 speak-

ers from a single 20A, 240V AC circuit, thereby allowing a margin for line loss

and/or lower than normal voltages.

To determine the total current requirement for a system of powered loud-

speakers, simply add their Maximum Continuous RMS Currents together,

then calculate a safety margin of 25% or greater.

If special length AC cables are required for your powered speakers, they

should be constructed of durable, high-quality portable cordage such as S,

SO, or SJO type.

Chart 2 provides the basic guidelines of The National Electric Code for four

common gauges of copper wire related to permissible load in amperes.
