LUBELL SYSTEM 3400 Underwater Hailer
The Lubell Labs System 3400 is a high power underwater Diver Paging System designed for installation and use on commercial dive boats. Divers can be paged via included microphone, or background music can be played by attaching an mp3 player (not included).
The System 3400 can be connected to standard 12 volt marine electrical system, or connected directly to a 12 volt battery or lighting “brick”. The mixer/amplifier features two 6.35 mm microphone inputs / volume controls, an auxiliary 6.35 mm input, and includes a noise-cancelling microphone with locking PTT switch.
The patented Lubell LL916C underwater speaker is a state-of-the-art piezoelectric underwater acoustic transducer utilizing the Tonpilz design. The advantages to this remarkable design include a broadband response (200Hz-20kHz), high efficiency (60% @ 1kHz), and an output level of 180dB/uPa/m @ 1kHz.
The LL916C is extremely rugged by virtue of it’s protective cage. The LL916C operates at all pool depths, and may be used in the lake or ocean* at depths up to 50′.
