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/E77ESD’s 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 non-magnetic and non-conducting materials and this eliminates magnetic hysterisis distortion caused by transformers, capacitors, transistors, etc. Abundant functions • Audio input selectors control 7 audio and 3 video signals. • 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.
