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

g repeatedly to select the desired
programmed mode within 4 seconds.
“DSP SURROUND” appears and the DSP SURROUND mode is
displayed cyclically as follows.
DISCO
LIVE
MOVIE
HALL
STADIUM
Equalization curves are selected automatically to match the DSP
SURROUND modes and can also be manually 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.
3-AMP PANORAMA SOUND SYSTEM
Aiwa’s unique 3-Amp Panoram Sound System uses Satellite
Speakers driven by a separate stereo amplifier circuit to achieve
a wide sound stage and clear stereo imaging at the same time.
Press SATELLITE to activate the 3-Amp Panorama
Sound System.
The SATELLITE button light turns on and output from the satellite
speakers is activated.
For proper positioning of the speakers, see page 4.
To cancel the 3-Amp Panorama Sound System
Press SATELLITE again. The button light turns off and output
from the satellite speakers is disabled.
How the 3-Amp Panorama Sound System works
Generally, placing the speakers farther apart gives you a wider
sound stage. Its cost, however, is loss of clear sound imaging.
When reproducing music, for example, the position of instruments
within the sound stage becomes obscure.
Placing the speakers close to each other gives you clear stereo
imaging; you will easily be able to tell which instrument is playing
where in the sound stage. But stereo spreading, in turn, will suffer
gravely. Presence is lost, and you must stay close to the speakers
at all time.
Aiwa’s 3-Amp Panorama Sound System, by a practical application
of psychoacoustics, gives you only the benefits of these two
speaker settings.
The front speakers are placed close to each other, and a pair of
“Satellite Speakers” is placed outside the main speakers. The
satellite speakers are driven by a dedicated 2-channel stereo
amplifier, and reproduce the same sound as that from the main
speakers with a 9 milli-second delay.
