Rockford Fosgate FA15.0 - Manual (Page 6)

– 1 –
The FA10.0, FA12.0, and FA15.0 monitors utilize a specially designed amplifier featuring our innova-
tive Trans•ana circuitry. This topology, with its unique input-to-output configuration (derived from
our patented Trans•nova circuit), employs power gain in the MOSFET output stage that result in
superior sound quality.
The amplifier features an auto turn-on/off circuit that eliminates the need for a conventional power
switch. Input signals can be fed into the amplifier via Un-Balanced RCA jacks or Speaker level input
jacks. Each pair of inputs is combined into a mono-summed signal before being fed into a 4th order
Linkwitz-Riley low-pass crossover, adjustable from 40Hz~140Hz. If selected, the signal is then fed
into the Phase Control that allows the phase of the signal to be adjusted at 90˚, 180˚, or 270˚ incre-
ments.
The FA10.0 is a 10” (254mm) low frequency transducer that features a 2” (51mm) voice coil and is
driven by a 30 oz. magnet. The FA12.0 is a 12” (305mm) low frequency transducer that features a
2.5” (63.5mm) voice coil and is driven by a 102 oz. magnet. The FA15.0 is a 15” (381mm) low fre-
quency transducer that features a 2.5” (63.5mm) voice coil and is driven by a 153 oz. magnet. All
Point Zero transducers feature Cellulose Fiber cones for accurate sound reproduction and Santoprene
Rubber Surrounds that are immune to temperature fluctuations. This specialized rubber surround
controls woofer damping and reduces 2nd harmonic distortions for a very wide and flat frequency
response. The Point Zero series voice coils are 4-layers of copper wound on aluminum formers.
Aluminum voice coil formers provide excellent heat dissipation that provides higher power handling
versus plastic or Kapton type formers used by other manufacturers.
Introduction
Technical Design Features
T hank you and congratulations on your purchase of the Point Zero series of Subwoofer, from the
world's finest brand in professional audio equipment.
The Point Zero series is comprised of three modules; the FA10.0, FA12.0, and FA15.0. The FA10.0 is
an amplified 10" subwoofer. The FA12.0 is an amplified 12" subwoofer and the FA15.0 is an ampli-
fied 15" subwoofer. All Point Zero series are designed and engineered for Home Theater Systems
and high performance home audio applications.
For ease of use, this manual is organized into two main sections: Installation and Operation.
"Installation" covers the set-up of your new Fosgate Audionics equipment to the system. "Operation"
covers the controls and how to use them for optimum performance.
