Hi all,really need some info.I seen a lot of setup which included EQ. Do I need a 15or31 band EQ? What does an EQ do exactly? Currently I only have keyboard(PSR2K)-mixer(RQ200)-sonic maximizer-amp(soundtech PL200)-speaker(Peavey impulse652).I am not satisfied with the output sound as it lack clarity.Does adding EQ helps?How do I tune an EQ?
What does a compressor/limiter do?
ThankQ very very much.
