INTRODUCTION
Several new features appearing for the first time in these two LINEAR POWER™
amplifiers include: true compatibility to 2 ohm and 4 ohm speaker impedances,
switchable Bridged Mono capability, a turn on delay to avoid speaker damage,
control circuitry for an optional cooling fan, and the new "Dynamics Improving
Processor
" circuit. The "Dynamics Improving Processor
" provides a well

controlled and precise redistribution of power in the bass region to help
overcome the factors in the mobile environment that work against the auto-sound
installer: poor speaker placement, the masking effect of a car in motion, and the
natural tendency of most speakers to roll off too soon in the low bass region. The
net result is accurate musical reproduction that you can take with you. Isn't that
what it's all about?
TECHNICAL DESCRIPTION
POWER SUPPLY: Self oscillating for reliability and efficiency. The transformer is
epoxy dipped for extreme vibration resistance. Banks of high-speed TO-3
switching transistors provide massive current reserves. LINEAR POWER™
amplifier design incorporates an unregulated power supply for increased dynamic
headroom and efficiency.
OUTPUT STAGES: Transformerless, direct coupled and fully complimentary.
Output transistors are high current and low distortion TO-3 devices, operating at
a fraction of their limitations. The TO-3 output stages of these amplifiers will
deliver a significant increase in power into 2-ohm stereo loads. Amplifier reliability
is accomplished by operating the output transistors at 50% of their maximum
rating even into a 2-ohm stereo load. In 4-ohm stereo, the output devices, in the
5002™, work at less than 30% of their design capabilities as engineered by
Motorola. Linear Power™ products are seriously over built!
PROTECTION: Our stable amplifier design is made virtually indestructible by two
protection circuits. One is a precision thermal protection circuit, which prevents
damage from high frequency oscillation, or an excessive ambient temperature.
The second protection circuit is a current sensing device guarding against
instantaneous abnormalities, such as short circuits. Both circuits are
