Applications include restaurants, retail stores, coffee shops and other commercial establishments. The system includes the Crown 140MAx tunermixer- 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. 140MAx Specifi cations Performance Frequency Reponse (at 1 watt from 4-ohm tap): 80 Hz to 15 kHz ± 1 dB.
