INTRODUCTION

YSS906 is an LSI for processing signals that uses Yamaha’s original wide surround technology,

“YMERSION™”, and the tone control/loudness circuit that is built-in the device.

This LSI has the following features.

1. In addition to normal stereophonic input signal processing function, this LSI uses the pseudo-

stereophonic sound processing function to give listeners a feeling of extended sound field.

2. Offers the wide surround effect by using “YMERSION™” technology.

3. Use of tone control/loudness function can emphasize specific tones.

When reproducing music in compact audio appliances such as the arcade game or other game applications,

YSS906 is particularly suited to meeting the need of adding a feeling of extended sound field or emphasizing

specific bass or treble tones. This LSI does not require use of the microcomputer, A/D and D/A functions and

memories because it uses analog signals without converting them to digital signal.
