PKI 9340 is a high performance loudspeaker system constructed in an ultra-compact array format for excellent speech intelligibility at distances of 500 to 1000 metres.
It is one of the most powerful systems available world-wide in its size. Typical operational uses for the PKI 9340 Acoustic Hailing Device are:

• Support of logistics and operations management
• Sound reinforcement of large areas
• Civil unrest
• Large scale fires
• Hostage situations
• Rescue and search operations
• Evacuation from dangerous terrain
• Psychological warfare
• Securing a flight zone
• Training over large areas
• Public speaking with announcements

The use of high efficiency precision loudspeakers in combination with the latest in amplifier, battery and speaker technology, creates a superior performance within such a small package. The acoustic design of the PKI 9340 Acoustic Hailing Device allows the system to be cascaded to double the output of the system (+6db) and effective radius. Modern battery management allows operational battery life to be extended from 6 to 24 hours and for standby use up to 120 hours. The optional remote control allows operation even from an undercover position or while on the move. The robust folded aluminium housing has been developed for use by the military, police, fire and emergency services as well as rescue and disaster relief organisation.
