The 180MAx is the first integrated tuner mixer-amplifier designed for commercial use. Applications include restaurants, retail stores, coffee shops and other commercial establishments. The system includes the Crown 180MAx tuner-mixer-amplifier, four JBL© Control© 1ST 2-way miniature loudspeakers with built-in 25V/70V transformers, XM antenna, and a wireless remote control. 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. 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 amplifier provides 80 watts into 4 ohms, 25V and 70V for use with the JBL Control 1ST loudspeakers. Current and thermal limiting protect the amplifier and loudpeakers from accidental overload.
