Sony NSX-AJ80 manual Amppanorama Sound System, Selecting A Programmed Dsp Surround Mode

DSP SURROUND 3-AMP PANORAMA SOUND SYSTEM

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 or 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 STADIUMHALL MOVIE

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.

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.
