This diagram shows a full competition "Killer System" that has been
fine tuned using ORION Low Pass and High Pass Filters. An ORION
200 CRX Active Crossover is used to separate the high/mids from the lows.
The lows are then applied to a 400 BDG Bridging Module. The SUMMED
MONO output is supplied to two lows amplifiers that amplify the full spec¬
trum of lows selected at the 200 CRX (say 260 Hz and below). Each low
amplifier then drives two subwoofers. Up to 20 amplifiers could be connected
in parallel as shown here.
The high frequency output of the 200 CRX Active Crossover is applied to
two high/midrange amplifiers which reproduce the full spectrum of selected
high and mid frequencies (say 200 to 4200 Hz).
The high frequency output is also applied to an ORION 30 dBHP High Pass
Filter that selects a cutoff frequency that will emphasize only the highest
frequencies (say 4000 Hz and above).
An ORION 600 EQM Equalizer or 500 PMQ Parametric Equalizer is used to
balance the overall system.
The lows output of the 200 CRX Active Crossover is also applied to an
ORION 30 dBLP Low Pass Filter that selects a cutoff frequency that will
emphasize only the lower range (say 72 Hz and below).
