The ES Series:
The next step in digital audio, fromthe creator of the compact disc.
Sony has been the leader in both professional and home digital audio for over a decade. With such breakthroughs as PCM processors, Compact Disc Players and Digtal Audio Tape recorders. Now, the Sony ES engineerss, a dedicated group who are above the compromise between technology, convenience and price, have created the ES Series. Each component in the ES Series represents an ES engineer's dream. Once you.ve heard them, you'll want to own them.
The ES Series: Proof positive that Sony is still the leader in digital audio.
When the ES engineers created the ES Series, they had permanence in mind. These components will please their owners for years to come. All ES components, including our integrated amplifiers, tuners, cassette decks and digital processors, are designed with meticulous detail and built with extreme care. That's why Sony backs each ES component with a three-year parts and labor limited warranty.
The TA-E77ESD:
The future of digital signal processing.
The TA-E77ESD preamplifier provides three digital inputs for direct interfacing with both current and future digital components, plus decoding at three different sampling rates. It also has a digital processing loop for high-quality recording. The 4X oversampling, 16 -bit, dual D/A converters are totally shielded in a copper subchassis that prevents spurious noise from affecting the analog circuits. Direct coupling of the D/A converter simplifies the signal path and minimizes internal interference.
The TA-E77ESD includes many features that are difficult to find on other preamplifiers at any price. Even a programmable infrared Remote Commander that controls any brand of audio and video component with infrared operation.
