QSC designed the ISA 300Ti as a cost-effective solution specifically with sound contractors in mind. The ISA 300Ti can drive both eight and four ohm loads and a distributed system on the same channel at the same time, allowing you to reduce the number of amplifier channels needed to power the speakers from the same amp. This rugged power amp can output 25, 70, or 100 volt to accommodate distributed audio systems, making this the perfect power amp for countless installed in-ceiling systems. Add QSC sound quality to your system with the ISA 300Ti!
