WARNING · Power Supply Ensures the source voltage matches the voltage of the power supply before turning ON the apparatus. Unplug this apparatus during lightning storms or when unused for long periods of time. · External Connection The external wiring connected to the output hazardous live terminals requires installation by an instructed person, or the use of ready-made leads or cords. · Do not Remove any Cover There are maybe some areas with high voltages inside, to reduce the risk of electric shock, do not remove any cover if the power supply is connected. The cover should be removed by qualified personnel only. No user serviceable parts inside. · Fuse To prevent a fire, make sure to use fuses with specified standard (current, voltage, type). Do not use a different fuse or short circuit the fuse holder. Before replacing the fuse, turn OFF the apparatus and disconnect the power source. · Protective Grounding Make sure to connect the protective grounding to prevent any electric shock before turning ON the apparatus.

You have acquired an extremely efficient and universal stereo crossover with an integral BBE® Sonic MaximizerTM. GETTING STARTED READ BEFORE USING Before starting to use the crossover in your sound system there is some information you should know and procedures you should follow. The Max-X3 is a fourth order Linkwitz-Riley electronic crossover. These units can be used both in stereo and mono modes allowing the following configurations: · Stereo mode 2-way · Mono mode 3-way Stereo and mono modes can be easily set by pushing the rear panel switch and connecting inputs and outputs properly. FEATURE LIST · Single rack unit (1U) · Robust and compact design · Phase inversion switches · Servo-balanced XLR inputs/outputs. 1/4"TRS input/outputs for any combination of balanced and unbalanced operation · State-variable Linkwitz/Riley 24dB/Octave filters · Switchable Constant Directivity horn equalization circuit for use with horns requiring a high frequency boost · Clip LED indicators · Mute switches · Designed for the most precise control · Top audio performance with high slew rate circuity · Over 115dB dynamic range · Manufactured Under ISO9001 Certified management system INPUTS & OUTPUTS All inputs and outputs are floating and balanced when connected via a tip, ring, sleeve 1/4" connector to other floating and balanced equipment. Any combination of balanced and unbalanced operation is permitted (see also "Connection Cables"). SONIC MAXIMIZER Loudspeakers have difficulty working with the electronic signals supplied by an amplifier. These difficulties cause such major phase and amplitude distortion that the sound reproduced by speaker differs significantly from the sound produced by the original source. In the past, these problems proved unsolvable and were thus delegated to a position of secondary importance in audio system design. However, phase and amplitude integrity is essential to accurate sound reproduct ...
