Overview

The EF500P redefines performance in a high-power professional active
loudspeaker enclosure. Utilizing the popular élite EF508 as a base, and
adding a total of 1000 watts (program) of bi-amped power and advanced
signal processing, the EF500P is destined to set a new standard for active
loudspeaker design. The woofer or low frequency amplifier uses Class D
switching technology to reduce overall weight of the amplifier section.
This solution allows the horn to produce loud clean transients to keep up
with the high output of the woofer.The two-tier amplifier technology isn't
typically seen in a product like this, however we found the advantages
(lower weight, more efficiency, higher headroom and lower operating
temperature) made it a perfect choice for powering the top end.

This combination of amplifier technologies keeps distortion to a minimum
while reducing the heat dissipation to a level low enough to eliminate the
need for heavy heatsinks for the overall power stage. As an additional
advantage, our unique combination of two-tier and Class D amplification
has reduced extraneous heat to the point that EF500P can easily be used in
any orientation, and close to walls, floors and in close arrays with multiple
cabinets. We have found that competitive active loudspeakers with large
finned heatsinks need to be operated vertically and with clearance to
ensure proper heat dissipation and ventilation. Since the EF500P is ideal for
flying in large clusters and in point source concert sound systems, our
designers took extra care making sure that in tight clusters overheating
would not be an issue.

We've also found an opportunity to tweak the electronics for maximum
overall speaker performance and protection. Borrowing some ideas from
our powerful and popular TX Series PA systems, the limiters used in the
input and crossover stages are a complex combination of gain reduction
and sweeping filters. As the EF500P is being pushed to its maximum input
/ output levels, it's advanced filtering begins rolling off unnecessary

any mix, like the vocals or solo instruments, come out clean and clear when

excursion. Extremely fast and accurate limiting is in place to protect the

The EF500P has a built in mixer allows the loudspeaker to be used
directly with a microphone and / or line source. The loop output allows
additional active cabinets to be driven from one cabinet's mixer stage,
or a series of cabinets to be driven from one source. If desired, the end
user can combine a pair of the EF500P's using the mixer inputs on each
cabinet and coupling the loop outputs. In this simple example you would
have the ideal presentation system with two microphone inputs, two

allows looped cabinets to be individually adjusted in level. This is
invaluable in applications where large numbers of cabinets are used
such as clusters or in trade show applications or when EF500P's are used
as repeater cabinets or for side fill. The 100 Hz high pass filters allows
the EF500P to be used more efficiently with any active subwoofer.
