LS300 Series

The LS300 Series Talkback Loudspeaker Outstations are designed to cover a wide range of applications at a 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.

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

The table top / wall mount version is fitted in a reversible angled metal box. When wall mounted, the front panel can be angled up or down, depending on which is most convenient for the height at which the station has been mounted.There is an additional user option to mount the connector, or make a cable exit in the rear face of the box. Keyhole slots are provided for wall fixing.

Note: Care must be exercised when using LS300 Series Loudspeaker Station in hands-free duplex applications. The unit deliberately contains no vox switching to prevent loss of syllables. While excellent side-tone rejection prevents the unit feeding back to itself, system feedback can occur if several hands-free units are in simultaneous use, or if headsets on the circuit are removed when turned up to a high volume. Using the LS300 in push-to-talk mode, or with a headset will help prevent feedback occuring.

Suitable for use with Series1 and Series 2 products.
