®
140MAx Pack is the fi rst tuner-
mixer-amplifi er and loudspeaker system
designed for commercial use. It is designed
for easy installation by the user. Applications
include restaurants, retail stores, coffee shops
and other commercial establishments.
The system includes the Crown 140MAx tuner-
mixer-amplifi er, two JBL
®
Control
®
1S 2-way
loudspeakers, and two 25-ft. speaker cables.
Built into the 140MAx 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.
The unit also accepts signals from line, telephone,
or microphone (phantom power included). 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.
The built-in power amplifi er provides 40 watts into
a 4-ohm output (for use with the supplied JBL
Control 1S loudspeakers). Current and thermal
limiting protect the amplifi er and loudpeakers
from accidental overload.
