PX SERIES:PXB2:800 PROFESSIONAL CROSSOVERS
Designed to work in high-power cabinets, px crooovers are technically superior passive filters available as board-only or complete with fitted hardware for a smart, economical 'factory-fit' finish.
Designed and buit for Eminence, px crossovers feature advanced circuit design to both preserve the crossover and your HF drivers.
A common crossover problem in L-PAD failure brought about by winding burnout when maximum attenuation is prolonged.
Full attenuation concentrates the maximum voltage drop in a small winding area - a potentially damaging even with high-power L-PAD devices.
In px crossovers, current is limited when the hf level control is set to "0" on its scale (max. -9dB attenuation). A secondary benefit of the design is to form a voltage divider across the HF driver. The High-Pass Protection uses custom-built aerospace lamps as positive temperature coefficient series varistors.
The tungsten filaments effectively track the program material, dynamically maintaining a safe maximum current level to the HF driver without introducing distortion. This circuitry provides smooth 3:1 analog compression during input overload conditions over 250Wrams. At full drive level approaching clipping, the electrical attenuation to the protected HF driver is -4.5dB. In every way, Eminence px crossovers are a technically superior product.
