The LSA-X range is a battery powered high performance loudspeaker system with exceptional speech intelligibility and range.


Weighing only 6.8 kg (Mk1) and 7.2 Kg (Mk 2) the LSA-X is one of the highest performing, battery powered, systems in its class, worldwide. The three stage AP-LOCK™ system is a unique safety feature protecting users during commissioning and use, from health risks caused by excessive noise.


To avoid feedback, an ad-hoc recorder/play-back is built in to the microphone (Version ML-515R). This enables the user to record a message at the press of a button, then play-back the message with the microphone effectively turned off. thus eliminating the possibility of feed-back even on maximum volume.


The use of high efficiency precision loudspeakers in combination with the latest in amplifier, battery and speaker technology, results in superior performance within such a small package. This system enables you to transmit high quality speech content over distances up to 500 metres, thereby influencing the target audience in the most effective way. The acoustic design of the patented system facilitates the pairing of two systems thus doubling the system output and effective radius.


Modern battery management (depending on charger system employed – see technical specifications) allows extended use of up to 24 hours, and 120 hours on standby. Using the optional wireless microphone, located within the housing, the operator can maintain a distance of up to 100m from the unit. The optional remote control allows operation even from an undercover position or while on the move.
