 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.
