Page 7: Introduction
The APL-220, APL-500, and APL-800 are compact, bi-amplified speaker sys- tems capable of providing clean, undistorted sound at very high output lev- els. They easily form acoustically-correct arrays when used in multiples. - Page 8 These engineering advancements result in the following benefits: • All aspects of the loudspeaker system’s performance are maximized. Sonic quality, power output capability, flatness of response, distortion, and behav- ior under abusive conditions meet remarkably high standards. • Reliability is increased because the internal amplifiers deliver appropriate power levels to the drivers, without danger of over-powering or under- powering.

Page 9: Ac Power Requirements
Figure 1 Removal The AC PowerCon cable assembly provided with your APL-220, -500, or -800 is equipped with an AC mains plug compatible with the power service in the country of sale. If you need to change this plug or to construct special pur- pose power cables, the wiring must follow the convention shown in Figure #2. - Page 10 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-220, -500, and -800 at two standard international working voltages (120 & 240V AC). Because current...
- Page 11 We recommend powering no more than 2 APL-220, -500, or -800s from a single 15A, 120V AC circuit, and no more than 3 APL-220, -500, or -800s from a single 20A, 120V AC circuit, thereby allowing a margin for low voltages.

Page 14: Audio Signals
Audio Signals (1) Input Impedance and Level The APL-220, -500, and -800 were designed to receive a balanced-line signal on their 3-pin female XLR type connector. They are also equipped with a 3- pin Male XLR output connector, labeled “loop-through,” intended for the purpose of daisy-chaining multiple powered speakers together on a common signal feed. -
Page 15: Amplifiers
Unlike some competing designs, the amplifiers used in Apogee powered loud- speakers are designed to drive normal 4- and 8-ohm loads. Due to an excep- tionally high voltage swing, the Apogee design does not require unusually low impedance drivers in order to develop full power. Very low impedance driv- ers (1- or 2-ohm) have a low BL-product and typically exhibit poor damp- ening and transient response, resulting in a loss of clarity. -
Page 16: Installation
Instantaneous power is a sim- ple function of the peak voltage supplied to the speaker driver and the impedance of the driver. Apogee’s APL series' amplifiers use a 80-volt bus (V) with a 4-ohm driver (R). The instantaneous power calculation is:... - Page 17 Air flows through the cooling fins, increasing in temperature as it rises. If the APL-220, -500, or -800 are used in a horizontal position, air will not flow as readily through the fins. When placed horizontally, the fins act as obstacles to the airflow, and cooling efficiency is reduced.

Page 18: Signal Processing
Signal Processing (1) Basic Concept The APL-220, -500, and -800 use a highly-advanced signal processor con- tained entirely within the unit. The processor provides the functions of an eighth-order (48 dB/octave) electronic crossover, fixed equalization to com- pensate for driver/enclosure anomalies, time delay to acoustically align the low and high drivers, and advanced protective limiting circuits. - Page 19 (3) Driver Protection Apogee APL-Series speakers utilize a special, highly-evolved set of limiter parameters and controls. Multiple limiters are used simultaneously with attack, release, integration time, and slopes that have been carefully matched to the individual speakers thermal and mechanical limits over time.
- Page 20 Sound Pressure Level (SPL). (5) High-Pass Filter (HPF) Switch The APL-220, -500, and -800 are equipped with a switchable High-Pass Filter. The filter is of the 12 dB/octave type with a corner frequency of 80 Hz. The...
- Page 21 (6) When to Use the High-Pass Filter Switch The High-Pass Filter Switch is very effective when the APL-220, -500, and - 800 are utilized with subwoofers, or other larger speaker systems. For example, a system may be made up primarily of FH-4s, 3X3s, or other large concert type speakers, with APL-500 speakers flown below them for downfill.
- Page 22 (10) Indicators The APL-220, -500, and -800 have a green LED labeled PWR (Power) that indicates AC mains power is applied and the power supplies are functioning properly.

Page 23: Using The Apl-220, -500, And -800
(1) Overview Using the APL-220, -500, Despite their small size, the APL-220, -500, and -800 are powerful pieces of equipment that can be utilized in an extremely wide range of applications. and -800 They are highly effective when single units or pairs are deployed as a basic PA system for live music, track playback, and the spoken word. - Page 24 For many applications, a ratio of two, three, or four APL-220, -500, and -800 speakers to one subwoofer is a good starting point, however, the optimum ratio may vary according to your specific needs, the style of music to be reproduced, the acoustical conditions of the venue that the system will be operated in, and the model of subwoofer.
- Page 25 That is the phase relationship of the two systems, although absolute phase also plays a role in the equation. If the subwoofer is directly under or over the APL-220, -500, or -800, in near- ly all cases the polarity of the subwoofer should be normal, that is, the same as the APL-220, -500, and -800.
- Page 26 (a) The low-frequency peak in the overlap region can be filtered out with an equalizer. (NOTE: Usually equalizing only the full-range system is sufficient. To this end Apogee’s powered full-range speakers are equipped with a 80 Hz high-pass switch, making it easy to adapt them for use with subwoofers).
- Page 27 In such a case, an easy way to determine the best phase relationship is to lis- ten to a low-frequency source while standing in front of the system and have someone swap the phase relationship of the subwoofer from Normal to Reverse while you listen.
- Page 28 For safety reasons, it is important that the tripod or mast-type stand be capa- ble of supporting the weight of the APL-220 (75 lb. /34 kg), -500 (80 lb. / 36.2 kg), or -800 (94 lb. / 42.6 kg). Generally speaking, only the largest and best- constructed stands meet this requirement.
- Page 29 (6) Flying the APL-220, -500, and -800 For many applications, the APL-220, -500, or -800 may need to be flown. This requirement commonly occurs in television work, political conventions, the- atrical productions, rock concerts, permanent installations, and numerous other applications. Flying an APL-220, -500, or -800 or an array of them offers many advantages –...

- Page 31 Apogee manufactures many rigging accessories for the APL-220, -500, and -800. Some of these are: • Yokes that allow a single APL-220, -500, or -800 to be fastened to a wall, ceiling, or theatrical pipe and easily adjusted vertically and horizontally (Figure 8a).

Before attempting to replace any parts in the APL-220, -500, or -800, be cer- tain to disconnect the power cable from the unit. Lethal voltages are present... - Page 33 NOTE: If the driver is connected backwards (out of phase), it will not func- tion properly and could be damaged if used adjacent to other APL-220, -500, or -800 speakers in an array.
- Page 34 The processor/amplifier package consists of a heat sink assembly attached to the rear of the APL-220, -500, or -800. It is accessible only from the rear of the loudspeaker. The heat sink is held in place by twelve (12) Philips drive fasteners.
