DSP SURROUND
The DSP (Digital Signal Processor) SURROUND adjusts the
delay time, the input mode and the feedback level to give a
resonant surround sound, allowing you to enjoy the real sound
presence of different environments.
This unit has been programmed with 5 different SURROUND
modes.
SELECTING A PROGRAMMED DSP
SURROUND MODE
Five modes of DSP SURROUND offer the sound presence you'd
experience in disco (DISCO), at a live concert (LIVE), stadium
(STADIUM), in a concert hall (HALL) or movie theater (MOVIE).
(Shown in parentheses are indications appearing in the display.)
Press SURROUND, and turn MULTI JOG or press
f f g g
f or g f f g g repeatedly to select the desired
Programmed mode within 4 seconds.
"DSP SURROUND" appears and the DSP SURROUND mode is
displayed cyclically as follows.
LIVE STADIUM
DISCO
Equalization curves are selected automatically to match the DSP
SURROUND modes and can also be selected or turned off to
suit your preference.
To display the current DSP SURROUND mode
Press SURROUND. The current mode is displayed for 4 seconds.
To cancel the selected mode
Press SURROUND twice. "DSP OFF" appears and "DSP
SURROUND" disappears.
When the music source is monaural
Select "LIVE", "STADIUM" or "MOVIE" to obtain a simulated stereo
effect.
When "DISCO" or "HALL" is selected, no sound will be heard
from the surround speakers.
4-Channel Multi-Amplifier System
To provide reinforcement for the ultra-low frequencies, in addition
to the Left/Right 2-channel amplifier used to reproduce mid-to-
high-range frequencies, this system incorporates a second L/R
2-channel amplifier just for reproduction of ultra-low frequencies
— making it, in effect, a 4-amplifier system. By utilizing discrete
amplifiers for mid to-high-frequencies and low frequencies, high-
quality sonic reproduction that is virtually free from distortion can
be realized.
This Multi Amplifier System, which utilizes independent circuitry
for the different frequency ranges, enables superb sonic
reproduction free from distortion.
Built-in Subwoofer System
The built-in subwoofer system has a separate subwoofer cavity
area that is part of the loudspeaker cabinet structure, which acts
as a sonic filter to cut distortion components. (In the Multi Amplifier
System, the ultra-low frequency signals transmitted from their
own independent amplifier are reproduced in this area.) This
separate construction gives a clear, rich definition to bass
reproduction and it can realize clear, well-defined mid-to-high
frequency signals.
And AIWA's built-in subwoofer system incorporates a subwoofer
capable of powerful, satisfying bass performance with true stereo
separation.
