The Concept

of Integration

Why a Powered Loudspeaker?

Apogee’s powered speaker systems further the concept of processor-based

loudspeakers. By combining advanced electronic signal processing with pre-

cisely matched amplifiers and integrating this package into the speaker enclo-

sure itself, a number of engineering improvements result. Some of these are:

• The internal signal processor corrects driver and enclosure anomalies, and

provides required crossovers, time-domain alignment, and protection cir-

cuits.

• The amplifier’s power output, headroom, frequency response, and dynamic

range are optimized for each model of loudspeaker system.

• The gain structure of the signal processor and amplifiers are always per-

fectly matched.

• The amplifier output cables are kept to very short lengths, thereby reduc-

ing cable losses to nearly zero.

Introduction

Apogee Powered Loudspeaker Systems are highly-engineered products that

combine advanced-technology amplifiers, sophisticated signal processing, and

state-of-the-art drivers housed in rugged, roadworthy loudspeaker enclo-

sures. They are suitable for a wide variety of applications, ranging from

portable use for shows and events in all types of venues to permanent instal-

lations in auditoriums, churches, theaters, stadiums, meeting rooms, board-

rooms, and similar locations.

The APL-10, and APL-12 are large format, high-powered subwoofers, capable

of providing clean, undistorted low frequency sound at very high output lev-

els. They form powerful arrays when used in multiples with like units. The

enclosures are designed for easy truck-packing and handling, and can be safe-

ly flown from their built-in rigging points. They are designed to augment

Apogee’s full-range powered speaker family, but they are equally effective

when used with conventional, non-powered loudspeakers. The APL

-10 and APL-12 feature extended bass down to 34 Hz and 32 Hz, respec-

tively, rapid transient response, and exceptionally low distortion, making

them capable of fulfilling a wide range of professional sound reinforcement

requirements.

Apogee powered products are exhaustively engineered and finely crafted.

They will provide years of trouble-free service if care is taken in their use and

maintenance. It is recommended that you read this manual and retain it in a

convenient location for future reference.
