*Sound4 HQSound: Our customers say  this is the most incredible dynamic processing engine ever made…
Why does HQ Sound give such good results?
The results of our extensive tests prove that HQSound, the new algorithm engine specifically developed for our range of products, offers on average 20 times more power than those commonly used in competitors’ products. So, with 4 bands and no other peripherals in front or behind it, HQSound can rival and even surpass processing chains made up of several processors in series
