FEATURES

Higher sound quality

Sony performed numerous experiments and trials to
determine the best chassis structure for an amplifier capable
of top quality sound reproduction with superb dynamics,
response and presence. The results provided the basis for
the TA-E77ES/E77ESDs chassis design. The chassis, named
Gibraltar, is solid as a rock to avoid internal vibrations
caused by power transformers, power transistors, and other
amplifier components and stress from the outside caused by
floor vibration from speakers, home appliances, and other
sources. Additionally, the chassis is made of nonmagnetic
and nonconducting materials and this eliminates magnetic
hysterisis distortion caused by transformers, capacitors,
transistors, etc.

Abundant functions

0 Audio input selectors control 7 audio and 3 video signals.

0 Input source selection can be remotely controlled by the
supplied remote commander.

~TA-E77ESD provides digital input and output jacks.
These deliver excellent sound reproduction with digital
audio equipment.
For the model in USA and Canada only, a programmable
commander is supplied. This can remotely control almost
any Sony audio and video equipment. Further, it can read"
and store the functions of another remote commander
using an infrared ray transmitter, not only those made by
Sony but those of other manufacturers as well. With this
single commander, you can control your audio and video
equipment regardless of their manufacturers.
