Often specified for use as a scoring signal in the largest arenas and stadiums, the Model Q-3 Fig. 483 Air Horn provides a blast of over 140 dB @ 1 Meter. The Q-3 combines two tones for optimum effect. Configured as an omni-directional unit, sound can be evenly distributed throughout the facility eliminating problems with weak or excessive decibel levels in certain seating areas. A complete system can be designed for use with the Q-3 Air Horn including compressor kits and controls.
