power handling.3 x 1”(1.7”VC) custom neodymium compression drivers coupled to a waveguide with 100°H

x 15°V dispersion horn.The QSA 112 easy handle ( bi-amp mode) 600 watts on the lows and 300 watts on the

mid high section with a SPL 128,5 dB (LF)/138 dB (HF) .High quality passive crossover network offering maximum

reliability, with built-in soft thermal protection for the HF components with auto-reset.Bi-amp or

Fullrange passive mode selection from the rear panel. High Frequency Shelving EQ switch (-3dB, 0dB, +3dB),
