So, if you roll the two together and ask the QSC engineering team to pull it off, you can bet these experts in power amp technology will. The QSC PLX1804 is a perfect example of their work. This super-rugged, practically industrial-grade power amplifier does the job. It offers a high level of front-panel indication to keep you in touch with what's going on, while smart additions like the 21-position gain controls let you precisely set (and repeat) your amplifier settings. Looking for a rugged power amplifier? Look no further than the QSC PLX1804.
