,.,..,.....m .-

he Crown PS-2OO power amp is designed

as a lower power companion for the PS,

400. Like the 400 model, the PS-200 is
designed, built and available only for profes-
sional sound systems.

The PS-200 features a sophisticated circuit
that tracks low frequency amplitude to deter,
mine the allowable proportion of subaudio
output. The low frequency interrupt (user
defeatable by internal modification) detects
dangerous levels of sub-audio output.

The P8200 is another powerful, all-day
reliable Crown amplifier, unaffected by mis-
matches, shorted outputs or low impedance.

The Fs-200 is built around the Crown multi-
mode: circuit design, which provides utmost
reliability and sonic accuracy at all listening
levels. The mud/mode circuit, a three stage
AB+B design, functions at low levels as a
nonswitching Class A amp. At middle power
levels, the two-stage drivers continue as Class
A devrces With the output stages in Class B, At
high power levels, the mum-mode circuit drivers
function in the AB mode, with output stages
adding more Class B power. The multilmode
design uses output devices efficiently and
powerfully, minimizes amp distortion whether
audible or test-bench detectable, and provides
long-term reliability.

Crowns 3-Year No-Fault
Amplifier Warranty And 3+3
No-Fault Extended Warranty

Crown lnternational now offers a 3»
Year NoiFault Warranty for every new
Crown amplifier-an industry standard.
With this unprecedented NoAFault
protection, your new Crown amplifier is
warranted to meet or exceed original
specifications for the first three years of
ownership. During this time, if your
amplifier fails for any reason or does not
perform to original specifications, it will
be repaired or replaced at our expense.
This includes parts, labor and round-trip
shipping, even a shipping carton should
you need one. About the only things not
covered by this warranty are those
losses normally covered by insurance
and intentional abuse. And the coverage
is transferable should you ever decide to
sell your amp.

Thats not all; for a modest fee, Crown
will extend that protection for an addis
tional three years with our 3+3 No-Fault
Extended Warranty. Now thats commit
ment.

See your Crown dealer for full war-
ranty disclosure and details on the No-
Fault and 3+3 No-Fault Extended
Warranty.
