SONY TA-V55ES

Commentary

This ES series AV amplifier is equipped with the latest digital cinema sound technology and also supports DTS.

The new digital cinema sound technology has been introduced, and it is equipped with a cinema studio mode which adds the reverberation of the editing theater, a virtual 3D mode which further improves the expressive power of the height direction and the connection with the screen, and a virtual theater mode which combines the cinema studio mode and the virtual 3D mode.
Surround mode by DSP is equipped with all 28 modes.

A newly developed 32-bit DSP dedicated to sound field processing is installed so that large-scale sound field processing can be performed with sufficient margin.
A 24-bit DSP is used for decoding Dolby Digital and DTS.

The amplifier section uses a dynamic 5-amp system, and all five channels are on the same stage, enabling more powerful surround sound reproduction.

The power supply section is equipped with a large power transformer using a wrapped core.
In the conventional EI core transformer, E-type and I-type magnetic steel sheets are individually laminated and then combined (welded or bonded) to form the core. In the wrap-packed structure, I-type and E-type magnetic steel sheets are stacked alternately on E-type magnetic steel sheets to form the core. Since there are no faults in the magnetic path, leakage of magnetic flux is reduced and the influence on the audio circuit is reduced.

The heat sink uses a large extruded aluminum heat sink tuned to reduce harmful fin squeal. The heat sink itself is also firmly fixed to the chassis body to reduce vibration structurally.

The legs are equipped with an eccentric insulator.
In this insulator, a screw hole is provided to avoid the center position, and by changing the phase of the vibration transmitted from the floor, it is canceled, and it is difficult to transmit to the chassis.

Equipped with AC-3 RF input to support Dolby Digital laser disk.

Equipped with a 5.1 ch input terminal, which can also be used as an input terminal for 3-1 stereo.

Wireless remote control is included.
