Sony TA-E1000ESD

Digital Processing Control Amplifier (1989-92)An AV control amplifier equipped with Dolby Pro Logic and equipped with DSP developed with Sony's digital technology.

Equipped with DSP (Digital Signal Processor).
The sound heard at concert halls and other venues consists of three types of sounds : direct sound coming from instruments and other sound sources, early reflected sound coming after bouncing off walls and ceilings several times, and main reverberation sound coming later after following a complex path. DSP is developed with the concept of creating sound fields at concert halls and other venues by controlling the magnitude, direction, length, and interval of early reflected sound and main reverberation sound.
The TA-E1000ESD is equipped with two types of dedicated LSIs developed by Sony for the DSP : the CXD1355Q and the CXD1160. The CXD1355Q provides the DSP with the control of the DSP and also includes an 8 fs digital filter. The CXD1160 provides the DSP with the control of the DSP and the equalization.
With Reverblation Control, you can create both early reflections and main reverberation, and you can control the timing and level of early reflections, the timing and decay time of main reverberation, etc. to create a variety of atmosphere in a performance venue.
In the Sony DSP, the reverberation control is done in stereo, and the spread of the reverberation component to right and left can be expressed.
Dynamics Controls highlight low-level sounds and compress the overall dynamic range, making the subtle nuances of Pianissimo easier to hear.
For equalization, such as tone control, a digital signal processor (DSP) can be used to create a variety of variation curves, and in principle there is no difference in the curves between channels that occurs in analog circuits.

In the TA-E1000ESD, various sound fields are created by using and combining reverberation, dynamics control, and equalization.
In addition to the front 2-channel reverb control, the rear 2-channel is also generated by digital signal processing. Dynamics This roll can be adjusted in nine levels of compression (compressor) and expansion (expander).
Equalization is a 3-band parametric イコリ adder that can be increased or decreased in 0.1 dB steps up to ± 12 dB (1 dB on the bar graph) for each band. Also, Q (slope) can be selected from 4 types, and the center frequency can be set in approximately 90 ways in 1/9 octave (31 division on the bar graph).

A total of 10 types are preset : 9 types of surround sound selected from the sound patterns produced by DSP and Dolby Prologic surround sound.
The preset surround modes are Hall 1, Hall 2, Opera, Church, Jazz Club, Disco, Stadium, Live Concert, Theater, and Dolby Surround.

You can create a more desirable sound field based on preset surround sound.
First, there are three main parameters : room size, which controls the size of the venue ; walls, which control the frequency characteristics of the sound reflected by the wall material ; and seat position, which is also effective for correcting the AV viewing environment.
