Typical QSC Quality
Paired with the EV90 8" Speakers, this amplifier sounds fantastic.
We've used it as part of a large school auditorium space which hosts a range of events from musicals to parties.
The amplifier enables us to set limiters to match the speakers performance and lock the system out for better protection!
The onboard DSP is very user friendly with some very useful features such as delay and phase - something i wasn't expecting at this pricepoint.
Well worth the money! :)
excellent
very convenient settings. very convenient and informative menu. perfect solution with a screen. good sound quality. very light. The perfect solution for most speakers. very lack of bridge mode!
