Frequently Asked Questions
The Fischer Amps offer a uniquely defined spatial sound, often providing a more focused stage image, which some may prefer over the more neutral profiles of Shure or Sennheiser's offerings.
Yes, the 800N tensile load rating indicates a very robust cable designed to withstand the rigors of regular use and cable management on stage.
It means the soundstage feels wider and more precisely placed; instruments and vocals have distinct locations, which improves clarity and allows for better mixing decisions during performances.
