The Sony TA-E1000ESD digital processing control amplifier -- sometimes called just the Sony 1000ESD -- is a preamplifier and processor for a home-theater system. Dating back to the late 1980's, this component represented the state of the art for its time. It combines a full set of analog audio and video inputs with the ability not only to route digital audio signals, but also to digitally modify sound. This allowed it to both support Dolby Pro-Logic surround sound in movies and to simulate various listening environments.
Analog Inputs and Outputs
Sony equipped the TA-E1000ESD with a full complement of analog inputs and outputs. It features dual-phono plug stereo audio inputs for a tuner, CD player, two tape decks, five video devices, a video-disc player, a television and a turntable. Its phono input includs a phono preamplifier, as well. On the video end, it has three S-video inputs, two S-video outputs, seven composite video inputs and 5 composite outputs. The TA-E1000ESD supports recording devices with two analog in/out loops and three video loops. In keeping with its role as a surround-sound processor, it has six line level outputs: a stereo pair for the front channels, a pair for the rear channels, a center channel output, and a subwoofer output.
Digital Inputs and Outputs
One of the TA-E1000ESD's distinguishing features is its support for multiple digital devices. It offers two TOSlink optical digital inputs and a single coaxial digital input. To allow digital recording, Sony also included an optical digital output for connection to the recording terminals of a Digital Audio Tape (DAT) deck or other piece of digital audio recording equipment.
Surround Sound and Digital Sound Processing Capabilities
With the ability to handle Dolby Pro-Logic surround, the TA-E1000ESD digital processing control amplifier was fully equipped to work with the state of the art in home theater equipment at the time of its release: Super VHS, ED Beta and LaserDisc players. In addition to supporting Dolby Surround, the digital signal processor (DSP) chip in the preamp enables a number of simulated surround modes. Used with music or nonsurround video content, they can simulate listening in a stadium, jazz club, concert hall or other venue. The DSP chip also provides a three-band parametric equalizer, allowing listeners to customize the preamp's frequency response to their system, as well as a digital dynamic range control to either expand or compress the difference between the loudest and quietest parts of a given piece of music or other content.

Sony built the TA-E1000ESD to run off of standard US wall power of 120 volts and 60 hertz, consuming no more than 35 watts for itself. The component measured 18.5 inches wide, 6 inches tall and 14.25 inches deep, although it required additional clearance in the rear for cables. Weighing 17 pounds and 11 ounces, it was clearly designed for home use.
