The LS300 Series Talkback Loudspeaker Outstations are designed to cover a wide range of applications at modest price. They can be used in a push-to-talk mode with the built-in microphone, or fitted with a plug-in gooseneck microphone for hands-free duplex communications. Alternatively, when required, plugging a headset or handset into the front panel turns the unit into a headset outstation, automatically muting the loudspeaker.

The override function is operated by an ultrasonic control tone generated elsewhere in the system. The LS300 series is designed to provide several functions in override mode as outlined in the features above. Override can be used to take control of the system by forcing all loudspeaker stations from talk into listen mode. Emergency announcements can be provided for by turning on outstations which are locally off. Alternatively, loudspeakers could be muted from a central location by presetting the volume to minimum, then activating override.
