Stereo dipole

g Outline

YSS901 is a device that uses the stereo dipole system (SD) with which the transaural system can be constructed.

When a stereophonic signal that has been processed with the SD system of this device is inputted to two

speakers located adjacently at the center of the field (or to two speakers contained in one cabinet), the virtual

sound positioning function of this system produces the stereophonic sound similar to the one that can be

obtained by using an ordinary stereophonic sound replay system through the central two speakers.

YSS901 has built-in one bit Delta-Sigma type A/D and D/A converters for each of the two channels at its input

and output respectively. Thanks to these built-in converters, this device can process analog stereophonic sound

signal through the converters in addition to digital stereophonic sound signal.

This device performs an advanced convolution through DSP using the FIR filter.
