Frequency shift general education classrooms amplifier is specifically tailored for the complete
set of professional sound reinforcement equipment ,but also to satisfy the courts and agencies,
military units , enterprises and institutions use the conference room sound , with a high cost .
Against the small particularity in public places , which focus on solving the sound stability ,
sensitivity and sound clarity of these three problems , effectively suppressing acoustic feedback ,
significantly attenuated the microphone whistle, to ensure high-quality sound effects.
