The innovative design of the F6-MF allows the
amplifier to be configured to suit the individual
amplification and sound system requirements of
a variety of applications. This functionality makes
the F6-MF the most flexible, energy efficient
amplifier on the market today.

is designed to route any and all available energy to the
channels that require it. This innovative feature known
as Power Rail Direct Coupling™, or PRDC, technology
enables channels that demand more energy to benefit
from the pooled resources so it can deliver more power,
more efficiently”

The F6-MF chassis can be fitted with up to six
uniquely engineered amplifier modules. The straight­path design of the F6-MF is the essence of simplicity;
yielding clean, accurate, and dynamic sound. The
FM250-4 (4Ω/8Ω) and FM250-70 (70.7V) power
modules can be loaded into any of the six F6-MF
amplifier card slots and are designed to deliver up
to 250 Watts per channel.

The Ultra Fast recovery switch mode power supply is
routed to each output module through quad-ganged
connector contacts, to minimize the impedance path
allowing for maximum current delivery. Each amplifier
module includes its own power supplied, high-current,
low ESR (Equivalent Series Resistance) capacitors which
provide immediate local, on demand current. This allows
each channel to produce clean, instantaneous, high­impact audio power. The direct coupled power supply

FM250-70 and FM250-4

The F6-MF Chassis can be purchased with up to six
FM250-4 modules, up to six FM250-70 modules,
or in any combination. Additional modules can also
be ordered as needed to satisfy future system or
purchasing requirements. The input design of the
F6-MF is based on an open architecture concept,
permitting application and installation flexibility. Six
balanced inputs via Phoenix termination feed a variety
of optional accessory interface cards, coming soon.

The F6-MF offers an Energy Save Mode called
“Standby”. The amplifier can be turned on remotely via
a Contact Closure (CC) or a DC Voltage of 5V – 24V. A
LED located on both the Front & Rear panels of the F6­MF indicates the operation mode of the amplifier.

The FM250 power modules are loaded with useful
features including front and rear channel status
indicators, selectable gain, signal limiters, 100Hz
Hi-Pass filter, bridge mode operation, and tamper­proof level controls. The FM250 Series Power
Modules are designed to be 90% efficient, allowing
the amplifier to run cooler and consume less energy
than conventional commercial amplifiers

The AA120 / AA240 amplifiers are an ideal solution
for large retail, commercial, or industrial paging and
background music applications. These powerful 120
watt or 240 watt amplifiers were engineered with
unique features to assist the contractor or installer in
today’s commercial business audio environment.

The 6 input units feature extensive muting and output
options along with a very unique bridge in / out feature
to allow combining of multiple amplifiers in ballroom
applications without the need for external relays. VCA
control is also included which may be assigned to the
BGM input or globally for the entire amplifier.
