UNIVERSAL
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.
