The 180MAx from Crown Audio is a four input, single output mixer/amplifier with an integrated XM radio tuner, which adds 160 channels of digital radio to your background music/paging system. A front-panel LCD displays the XM channel number and name, artist name, and song title. You can set up to 20 XM presets so your favorite channels are never more than a few clicks away. The other three inputs can accommodate line, mic, and telephone input signals.
Built-in priority ducking drops the volume of the background music when a microphone is used for paging. Bass and treble controls are provided for each input channel. A music-on-hold output is included for connection to a telephone system. The 80W amplifier provides a signal to 4 ohm and 25/70V outputs.
