User manual MACKIE PA152 DATASHEET

[. . . ] The system includes a high-level crossover network that features markedly lower (than conventional) induction values in series with the woofer. We call this innovation LICC (Low Impedance Compensated Crossover). The benefit is delay reduction, reduced phase shift and superior transient response.

The low-frequency transducer shall be a cone type loudspeaker having a cone diameter of at least 15 inches (380 mm). It shall have a voice coil of at least 4 inches (100 mm) in diameter. It shall present a nominal load impedance of 8 . Sensitivity shall be at least 97 dB when measured at 1 m with an input of 1 Watt and have a power rating of at least 350 Watts (AES), 1400 Watts peak. The high frequency section shall have a compression driver with a titanium diaphragm of at least 3 inches (76 mm) in diameter. It shall present a constant-impedance load of 16 . It shall be connected to a constant-directivity horn having a throat diameter of at least 2 inch (51 mm) and a nominal coverage pattern of 85° horizontal by 65° vertical. Sensitivity shall be at least 107 dB when measured at 1 m with an input of 1 Watt and the power rating shall be at least 75 Watts (AES), 300 Watts peak. The system shall be crossed over by an internal, highlevel, passive network having a response of 12 dB/octave. The nominal crossover frequency shall be 1. 6 kHz. The low-pass section of the network shall have minimum inductance in series with the low-frequency driver. The high-pass section of the network shall be equalized to optimize the performance of the constant-directivity horn. A dynamic high-frequency protection circuit based on a low-value, lowmass filament resistor shall limit the current available to the compression driver. A connection option shall be provided to disconnect the crossover network, but not the high-frequency protection circuit, from the drivers to allow bi-amp operation. [. . . ] New material, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current Mackie Industrial product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated. and are registered trademarks of Mackie Designs Inc.
