Powerflex multi-channel amplifiers use a state of the art, high-speed MOSFET switching
design with spread spectrum switching technology. This technology provides uncompromised
power with exceptional efficiency and superior audio fidelity. As the name implies, Powerflex
amplifiers satisfy many audio applications without compromising performance, all in a 3RU
package weighing 46 lbs. Four models are available and are specifically designed to drive
low impedance or 70 volt loads.
The Powerflex-4400 and -6250 shown on this page are four- and six-channel amplifiers designed
for low impedance applications. Channels may be used as individual, independent power amplifiers
with more than enough power to satisfy nominal audio applications, or they may be bridged in
pairs for applications requiring higher power. Additionally, the Powerflex 6250 has been designed
to drive six 25 volt or three independent 70 volt loads without the need of external transformers.
Each channel has a switchable high pass filter on each pair of inputs and level controls located on
the rear panel. Input connections are XLR/1/4? and euroblock. Output connections are 5 -Way binding
post. A quiet three-speed fan provides front to rear on-demand cooling.
Applications include: any multichannel power amplification application, monitor amp, small FOH
system amp, paging systems, cinema systems, boardroom audio applications, multiple zone restaurant,
bar, theme park or auditorium and DJ systems.
