YSS901
SD
Preliminary
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.
g Features
n Two channel virtual sound positioning by using the stereo dipole system.
n Processes analog or digital signals at each of the two channels.
n Four types of digital data format are available, including 48 fs Serial-DAC16, 18 and 20 bits, and 64 fs.
n Six types of parameter coefficients are built in the device. Additional parameter coefficients can be
downloaded externally.
n The parameter control is made through the DC switches or synchronous three-wire serial system.
n Uses a clock of 2.822 MHz from the crystal. External clock can also be used.
n Has a built-in PLL circuit for generating clock for operation.
n Internal operating frequency of 512 fs.
n Allows fading in or out the output of the results of the convolution when switching the coefficient.
n Power supply voltage: 5 V
n Si-gate CMOS process.
n 64 QFP
