INTRODUCTION
Congratulations
. With so much lower-quality car audio equipment currently on the market, you
have found one of the highest-grade,
All American
-made amplifiers produced today. Since
1975
we have manufactured the very best audio equipment for your car. Yes, we are
American
owned, designed, engineered and built in the USA,
and we are proud of it! All
LP Series©
amplifiers, also have a
4-year warranty**
to assure your investment in a
LINEAR POWER™
product was a wise choice. Our products are simple, yet flexible, and we are concerned about
giving you the absolute best sound quality and reliability possible. As you would expect, you will,
in the near future, see other new ideas and innovative products ranging from more amplifiers,
crossovers and preamps, from one of the industry’s oldest and most-respected amplifier
companies.
TECHNICAL DISCRIPTION
POWER SUPPLY:
Our mosfet-driven converter utilizes some of the highest current fets on the
market today as switching transistors. These transistors are protected by a unique non-interactive
over-current protection that does not regulate the power supply until maximum current is
achieved, unlike other manufacturers’ designs that fully regulate the power supply and, thus, limit
headroom and dynamic response. The power supply is extremely over built, with the transformer
capable of delivering more than 5 times the energy needed to run the output stage at rated
power. The power supply is also highly efficient, with the efficiency levels above 90 percent.
OUTPUT STAGES:
Transformer-less, direct coupled and fully complimentary, output transistors
are high current and low distortion and are the highest-sound-quality devices currently offered
from
On Semiconductor
(Motorola). These
TO-3P
devices are operating at a fraction of their
limitations and utilize the same style internal electronics as our old amps did, using the
TO-3
Metal
-cased transistors but just with a newer and better SQ part number. In
4-ohm stereo
, the
output devices in the
LP2075©
work at approximately
15%
of their design capabilities as
engineered by Motorola. Power is supplied to the outputs thru heavy-gauge, solid copper buss
bars, and the power is triple filtered at three separate locations to ensure the lowest noise and
distortion from the amplifier as well as the highest slew rate and transient response by having the
last filter and storage stage directly at the bank of output devices.
Linear Power™
products are
designed for serious sound quality, extremely over built and made to last!
**4-year warranty on all amplifiers that are dealer purchased and dealer installed; 1-year
warranty on all over-the-counter and Internet sales.
