The TGA-7201 boasts an astonishing 200 watts from each of its 7 channels. Copious power makes it a workhorse in 7.1 home theaters, yet at the same time the TGA-7201 is equally suited to 5.1 systems that require second zone operation. Sunfire developed its exclusive Tracking Downconverter™ technology for the coolest, most reliable operation no matter how hot the performance gets. This is unfire Optimized™, a powerful program that ensures your new amp is designed to perform optimally with other Sunfire electronics and our wide assortment of speakers too.
