Crown 180-MAX Brochure
180MAx
he 180MAx is the fi rst integrated tunermixer-amplifi er designed for commercial
T
use. It provides a unique, cost competitive,
higher performance alternative to traditional
programmed music services. Applications include
restaurants, retail stores, coffee shops and other
commercial establishments.
Built into the 180MAx is an XM Radio tuner that
receives satellite radio stations with digital sound
quality. A front-panel LCD screen displays XM
Radio channel data (channel number, channel
name, artist name, song title), 16 station presets
and signal strength.

Warranty completely protects your investment and guarantees its specifi cations
The unit also accepts signals from line, telephone,
or microphone (phantom power included). Bass
and treble controls allow the user to tailor the
tone quality of the sound system. The priority
ducking feature drops the volume of the background music when a microphone is used. A VOX
sensitivity setting controls how loud the voice
must be before ducking occurs.
Units can be linked to increase the number of
input and output channels.
The built-in power amplifi er provides 80 watts into
4-ohm and 25V/70V outputs for sound systemloudspeakers. Current and thermal limiting protect
the amplifi er and loudpeakers from accidental
overload.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown tuner-mixeramplifi er—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown mixer-amplifi er is warranted to meet or exceed original specifi cations for the fi rst three years of
ownership. During this time, if your mixer-amplifi er fails, or does not perform to original specifi cations, it
will be repaired or replaced at our expense. About the only things not covered by this warranty are those
losses normally covered by insurance and those caused by intentional abuse. And the coverage is transferable, should you sell your tuner-mixer-amplifi er.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside of the
USA, please contact your authorized Crown distributor for warranty information or call 574-294-8200.
