Commentary

A digital sound field processor with 16 built-in sound fields using a unique computer simulation method, 8 surround modes including Dolby Pro Logic Surround, digital equalizer and parameter adjustment function.

In order to create a realistic sound field, we analyze sound fields using a computer simulation method and gather them at 50 bitDSP.
The integrated early reflection system (I ・ E ・ R ・ S) mode, a new technology that takes into consideration the frequency characteristics of reflective surfaces such as walls and ceilings, is utilized to reproduce the effect close to that of reflected sounds generated in actual concert venues.

You can choose freely according to the character of AV software such as Dolby Pro Logic Surround which emphasizes the sense of sound localization such as dialogue and vocals, Dolby 3 ch Logic, Theater 1 and 2, Stadium, Studio, Simulated Surround 1 and 2, etc.
By adjusting the delay time, the surround sound field can be arranged freely, and it is also possible to store the surround sound field in the same way as the parameter arrangement of the sound field program.

The DSP allows computer simulation of all 16 types of sound fields such as halls, jazz clubs, churches and discos that are representative of the world.
Based on this program, it is possible to create an original sound field by further adjusting parameters.
Up to 16 unique parameter settings can be stored in the user memory.

The SP 700 d is equipped with a 7-element digital equalizer that can create a realistic and original sound field space.
The processing signal used for sound field control and the rear signal of the secondary signal can be equalized. The digital in a round process does not degrade sound quality and creates a subtle nuance of the sound field.
After equalization is set, it can be stored in user memory.

It has a complete stereo configuration from input to output, and the power supply circuit is divided into analog and digital sections to reduce internal interference.
It also features a 16-bit stereo A/D converter and a 16-bit 4-channel independent D/A converter with a 4 x oversampling digital filter.

Equipped with 7-row motor drive volume.

It comes with a wireless remote control that can perform all operations in the listening position.
It is also equipped with a test tone function for channel balance that can be easily controlled with a remote control.
