Sharp SD-AT1000 600 Watt Home Theater Audio System

The SD-AT1000 home-theater audio system presents an affordable version of a sophisticated digital amplifier from Sharp, which helped pioneer digital-audio amplifiers. The system includes a six-channel surround receiver, five satellite speakers, and a passive subwoofer, all of which are designed to be hooked up with a DVD player, satellite receiver, VCR, or other video sources so you can enjoy exciting music and sound alongside your video programs.

The SD-AT1000's amplifier uses a single-bit digital-to-analog converter that switches at an ultrahigh 2.8 MHz, more than 60 times faster than the clock used for CD audio, to deliver 40 watts per channel (x 6) of dynamic, ultraclear power across the entire range of audible frequencies (20 to 20,000 Hz), and up to 100 watts per channel at specific frequencies.

A pair of digital-audio inputs accepts Dolby Digital and DTS 5.1-channel surround signals, which the receiver decodes and routes to each of the system's speakers: one petite satellite each for left, center, right, and left/right surrounds, as well as a passive subwoofer with a 6.5-inch cone (the sub is driven by the same 40 watts as each of the other channels).

Dolby Pro Logic II generates 5.1-channel signals from any stereo (two-channel input), and the receiver's other connections include three analog audio (left/right RCA) inputs and a stereo output for feeding, for instance, a CD or minidisc recorder or a tape deck. Should you want to drive your bass to even greater depths (or merely louder levels), the receiver offers a subwoofer pre-amplifier output that can route a variable-level signal to an independently amplified subwoofer of your choosing.
