DESCRIPTION


The ALTEC LANSING Model 15595A is a fixedfrequency high pass crossover filter and combination horn/driver equalizer module. The module plugs directly into the powered octal accessory socket of the 9444A or any other Anniversary Series power amplifier product. When used with the 15594A low pass crossover module, they eliminate the need for rack mount electronic crossovers and offer the ability to individually equalize specific horn/driver (or woofer/ enclosure) combinations.
The third-order Butterworth high pass filter has an 18 dB per octave (60 dB per decade) roll-off rate. The modules are available in the following standard ISO frequencies: 125 Hz (15595A-125), 315 Hz (15595A-315), 500 Hz (15595A-500), 800 Hz (15595A-800), and 1,250 Hz (15595A-1250). Simple equations are provided to calculate other frequencies for custom applications.
Each crossover module is provided with a "flat" horn/driver equalization submodule. Optional submodules in the 9600-series are available to properly equalize almost any ALTEC LANSING horn and compression driver combination for a flat power response.
The 15595A is housed in a snap-a-part case which simplifies the installation of any submodules and eases service. All power is derived from the powered octal accessory sockets on the amplifiers. This negates any need for an external power source.
The ALTEC LANSING Model 15595A High Pass Crossover/Equalizer Module has the flexibility to meet or exceed the requirements for any job. Its ability to produce a flat power response for an individual horn/driver combination is not only useful but almost mandatory in today's professional installations.
