The Code 3 Banshee Siren Amplifier System (Model 3450) is a revolutionary new amplifier system that significantly changes how warning sounds are utilized in emergency response. The Banshee amplifier system offers a selection of tones, features, and options that have never been available in one siren amp system before. The only siren amplifier system with dual tone capability, low frequency, electronic air horn, plus additional built in specialty tones all in one box. Unique tones or tone combinations: 3 low frequency tones and special tones such as CommandAlert and Air Horn, can be activated while your primary siren tone is running to really grab a driver's attention. Works with one set of standard size speakers saving you a tremendous amount of time on installation and space where the speakers are mounted. The Banshee is designed to work in conjunction with a Code 3 Z3 Siren but can be used with any industry standard siren. Adding a Banshee to your system provides phenomenal audio impact especially at intersections and when traveling through high ambient noise conditions.
