QSC ISA300TI Two-Channel Power Amplifier 185W at 8 ohm / 280W at 4 ohm / 700W at 2Ohm / 500W at 70V QSC

Designed as a cost-effective solution specifically for sound contractors, the ISA300Ti features isolated 25, 70 and 100 volt outputs for distributed audio systems. Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.

Housed in a rugged 3-U chassis, the ISA300Ti features rear panel gain controls for tamper resistant operation with 2 dB detents for quick and repeatable settings. Inputs include both XLR and detachable Euro-style connectors. Outputs feature covered barrier strip connectors for safety agency compliance, and for added versatility, a DataPort V2 (Version 2) terminated with an HD-15 connector is provided for use with DPV2-compatible signal processing accessories such as the XC-3 Crossover, SF-3 Subwoofer Filter, LF-3 Low Frequency Filter and the DSP-3 with external power supply.Unique among distributed sound power amplifiers, the ISA300Ti will drive 8 or 4 ohm loads and a distributed system on the same channel simultaneously. This enables a contractor to reduce the number of required amplifier channels by allowing a limited number of distributed speakers to be attached to the same amp as is powering the main sound system.

• 185 watts/ch at 8 ohms
• 280 watts/ch at 4 ohms
• 430 watts/ch at 2 ohms
• 300 watts/ch at 70 volts

Selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA300Ti provides additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection.
