he 180MAx is the ﬁ rst integrated tuner-

mixer-ampliﬁ er designed for commercial

use. It provides a unique, cost competitive,

higher performance alternative to traditional

programmed music services. 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 back-

ground 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 ampliﬁ er provides 80 watts into

4-ohm and 25V/70V outputs for sound system-

loudspeakers. Current and thermal limiting protect

the ampliﬁ er and loudpeakers from accidental

overload.
