Designed for use as a scoring signal in smaller arenas and ice centers, the Model D-2 Fig. 282 Air Horn is an impressive unit. Providing a sound pressure level of over 138 dB @ 1 Meter, the D-2 combines two tones specifically recognizable as a scoring signal and far louder than truck horns. Configured as an bi-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 D-2 Air Horn including compressor kits and controls.
