THD-152

SELF CONTAINED ULTRA-HIGH POWER TRANSPORTABLE HAILING SYSTEM

 

The THD-152 is a complete, self contained acoustic hailing system. Based on the THD-146 components, it profits from the optimal coupling between the closely positioned horns to generate extreme acoustic output for clear highly intelligible voice communication over long distances. Its open compact frame make it easily transportable and quick to deploy in any situation. The THD-152 can be attached to any kind of hardware without the use of complex accessories like tripods or mounting frames. Three integrated keyhole mounting surfaces make it easy and quick to attach the battery pack and extra hardware accessories. 

Compared to conventional megaphones, the THD-152 provides many advantages:

  • High acoustic output: > 152db  @ 1m
  • Two highly efficient 2KWp classD power amplifiers
  • Two compact interleaved high power supply converter 
  • Innovative driver protection for maximum system efficacy
  • Long transmission range 
  • Directional acoustic beam with minimal side lobe energy 
  • Perfect intelligibility: STI > 0.88
  • Professional military grade connectors and cabling
  • All inputs fully protected against overvoltage and misuse 
  • Easily swappable battery pack
  • Low power consumption
  • Built-in charger with wide input voltage range allows charging 
    of the battery while in use for continuous operation
  • 2 Double sided keyhole mounting surfaces
  • CM1 holder in upper keyhole surface 
  • Robust marine grade aluminium frame
  • Heavy rubber feet for impact protection

CM1

Control Microphone

The CM-1 is a hand-held microphone providing an ergonomic remote control.

The CM-1 provides quick and easy access to the following features with a touch of a button:

  • Output level control. Including level presets accessed with a single button press;
  • Messages/Tones playback.
  • System and battery status.
  • Auxiliary Input level control.
  • Event log file.

The CM-1 Control Microphone is equipped with a high quality noise-cancelling unit which combines with a powerful DSP based feedback suppressor to increase the feedback threshold by more than 10dB.

This is a massive benefit in extreme reverberant acoustic environments.

The integrated memory card stores hours of pre-recorded messages or tones (WAV files). These can either be downloaded from a computer or recorded live on the microphone.

The CM-1 is delivered with 2 x metres rugged, flexible cable. An optional cable allows an extended distance up to 100 x metres using  the systems’ advanced electronic drivers.

Main Characteristics

  • Water-proofed: IP66
  • Pre-recorded messages and playback.
  • Output level control.
  • Store and forward.
  • Battery status indication.
  • LED display light dimming.
  • Auxiliary input.
