QSC ISA800Ti 2 channels, 450 watts/ch at 8Ω, 650 watts/ch at 4Ω, 1200 watts/ch at 2Ω, 800 watts/ch at 70V

Description QSC ISA800Ti 2 channels, 450 watts/ch at 8Ω, 650 watts/ch at 4Ω, 1200 watts/ch at 2Ω, 800 watts/ch at 70V The QSC ISA800Ti is, one of the ISA Installed System Amplifiers, professionally designed to meet the needs of the system contractors and designer all around the world. In this ISA system there are three models that features isolated 25, 70, and 100 volt outputs for distributed sound systems, while four low impedance models are rated for 2 ohm operation. The ISA Series is a rugged and cost-effective power solution, because of its comprehensive set of features and versatile loading options, for any permanently installed sound system. It is the QSC ISA800Ti 2 channels, 450 watts/ch at 8Ω, 650 watts/ch at 4Ω, 1200 watts/ch at 2Ω, 800 watts/ch at 70V. Features Low-impedance outputs plus isolated 25, 70, and 100 volt outputs for distributed audio systems Rear panel gain controls for tamper resistance; 2-dB detents allow for quick and repeatable settings.
