Qsc Llc ISA800TI Power Amplifier 800W 70V

Product Description

The QSC LLC ISA800TI is a power amplifier rated at 800 watts per channel at 70 volts, designed for professional audio distribution systems. Power amplifiers in this class convert low-level audio signals into high-current output capable of driving speaker loads across distributed audio networks. The 70-volt architecture makes this unit well-suited for commercial and large-venue installations where multiple speakers are wired in series-parallel configurations. Licensed audio-visual technicians and commercial electricians typically handle installation in engineered sound system projects.

The ISA800TI is used in commercial audio distribution applications including retail environments, houses of worship, hospitality venues, schools, and similar facilities that require a centralized amplifier driving zoned 70-volt speaker lines. It is intended for rack-mount deployment in dedicated audio equipment enclosures or mechanical/AV rooms.
