Sony TA-E2000ESD - Advanced Operation and Customization; Understanding Digital Signal Processing (DSP)

DSP (Digital Signal Processing) means that not only the digital signals but
analog signals from a cassette deck or FM tuner, etc. are also changed into
digital signals once and processed digitally in various ways. Afterwards, they
are restored to analog signals and output.
For this amplifier, digital signal processing is possible in the following three
areas, in any of these cases, press the respective button and adjust the
parameters. The adjustable parameters differ according to the sound field.
See page 33.
Parametric equalizer—PARAMETRIC EQ
Controls the specific frequencies or output level to raise
the bass sound or lower the treble sound.
Dynamics—-DYNAMICS
Compresses or expands the dynamic range of the
program source. The compressor increases the low
level sound and as a result, it compresses the dynamic
range, making passages played pianissimo audible, for
example.
Surround (Reverberation\—SURROUND
The sound heard in a place such as a concert hall or a
movie theater consists of direct sound, early reflected
sound (early reflections) and a reverberative sound
(reverberation). This amplifier reproduces the early
reflections and the reverberation using its digital signal
processing circuit and allows you to produce a variety
of sound fields in your own room.
