TECHNICAL DESIGN FEATURES
◆ trans•
ana
The trans•
ana
(TRANS conductance Advanced Non-multiplying
Amplifier) is a novel circuit that utilizes a short-loop complemen-
tary topology and advanced Real Time Protection circuitry.
THE RESULT: An amplifier design with the benefits of tube and bi-
polar transistor amplifier design without the limitations of either.
◆ MOSFET Devices
Rockford Fosgate is one of the few manufacturers in any of the
sound communities to utilize MOSFET devices in both the
power
supply
and the
output stages
.
MOSFET
(Metal Oxide Semicon-
ductor Field Effect Transistor) devices offer several important
inherent advantages over the 30 year old technology of bi-polar
design. These advantages include: thermal stability, switching
speed, ultra low output impedance and wider bandwidth linear-
ity. In addition, MOSFET and vacuum tubes share many impor-
tant operating characteristics. However, the MOSFET device is
much faster, wider in bandwidth, measurably lower in distortion
and far more linear than vacuum tubes.
THE RESULT: Operational characteristics of vacuum tubes
without the performance limitations of tube design.
◆ DSM (Discrete Surface Mount) Technology
The
DSM
(Discrete Surface Mount) manufacturing process com-
bines the advantages of both discrete components and integrated
circuitry. Rockford Fosgate is the only American amplifier manu-
facturer to have invested millions into this process. DSM compo-
nents differ from conventional discrete components in three
different ways. They are more compact and more rugged, and
they take much better advantage of the PC board to allow them
to get rid of any heat they generate. Using them wherever
appropriate allows the advantages associated with discrete thru-
hole circuitry to be retained while also providing room for both
highly advanced processing features and generous PC board
copper paths where needed. Their short lead-out structures allow
maximum audio performance and highest signal-to-noise ratios
