Crown 180MAX

The 180MAx is the first integrated tuner mixer-amplifier designed for commercial use. 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.

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-ohm and 25V/70V outputs for sound systemloudspeakers. Current and thermal limiting protect the amplifier and loudpeakers from accidental overload.
