The Powerline series from Carlsbro has revolutionised the PA amp market, by offering simply amazing power and features at previously unheard of prices. Since we started selling this range, it has supplanted virtually all our other ranges, and we now use this for all our hire and custom installation work, as this has outperformed amps we used to use which cost twice as much! The reliability has also been second-to-none. We really can't recommend these enough!
