Trian's Audia Flight amplifiers use current feedback, rather than the usual voltage feedback, for improved sonic performance. This new approach eliminates shortcomings of traditional voltage feedback designs, including lack of speed and transient instability when the feedback is relatively high. With current feedback, linear transimpedance amplification produces fast, stable circuits capable of controlling very reactive loads. In addition, the feedback is closed before the output stage.

Home Theater Projector
The ScreenPlay 7210 features new DarkChip3 DLP technology from Texas Instruments and the Faroudja DCDi 2310 deinterlacer to eliminate video image stuttering, scan lines, and artifacts. A simple keypad and backlit home theater remote make installation easy. The projector accepts eight video sources for easy connection to devices including VCRs, DVDs, component and RGB HDTV, and computers. A 12V screen trigger automatically raises and lowers an electronic screen when the projector is powered on or off.
