This UNIVERSAL Sound Program is acoustically designed with a slightly arched frequency response, along with a moderately aggressive compression speed. This ratio provides a boost in the speech range that is distinct, crisp and warm, coupled with a lightning fast compression for impulse noises, the response times are quick, smooth and seamless. We’ve acoustically perfected the The UNIVERSAL for beginner shooters, range masters and spectators.
The TRAINING Sound Program is aggressive, responsive and astute. We’ve Designed this for communication and speed. We’ve boosted the speech range, we’ve increased the timer frequencies, we’ve amped the frequency range of rounds hitting a 3/8 inch steel plate. The TRAINING Sound Program is informative, crisp, accurately satisfying. This Sound Program is amazing for training for speed!.
Focused, fierce and free, the COMPETITION Sound Program sheds all non-essential frequencies and amps only the crucial. The frequency range of a timer and your rounds hitting a 3/8 inch steel plate is all that is wanted. Unleashed and acoustically light, this Sound Profile is sharp but not penetrating with selective frequencies that isolate information that simply takes out the garbage and brings home the bacon.
The INDOOR Sound Program has a perfect tri-blend of boost in the speech range, compression ratio and max power output levels. These three combinations help clarify speech and still provide a solid quick protection acoustic wall.
The BLUETOOTH Sound Program will connect hands free and wirelessly to any Apple product. Non-Apple products need a go between neck loop accessory that can be ordered. BLUETOOTH Connectivity allows you to stream music and talk hands free on the phone.
