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-N77ES:
Apower amplifier worthy of the Sony ES name.
Even the most advanced components require superior amplifier performance. The TA-N77ES deliveres 200 watts of continuous power per channel into 8 ohms and has the operating stability to deliver 660 watts ofdynamic power into a 1 ohm load.
A Spontaneous Twin Drive design with separate voltage and current stages helps reduce cross-interference. And the oversized power transformer and high-current non-switching discrete output stage provide additional power on demand.
Specification:
200 watts per channel, both channels driven into 8 ohms, 270 watts per channel, into 4 ohms; Spontaneous Twin Drive (STD) design; 520 VA power transformer; non-conductive, low-resonance G-Chassis; high-current, non-switching discrete output stage.
