s Operational Description

The AN7395K and AN7395S are respectively equipped with the following devices :

• Type E Spatializer (Spatial Expansion)

It uses the ordinary stereo record and broadcasting as a sound source and can offer sound expansion exceeding speaker location.

→It provides natural sound effect which can not be obtained only with conventional two-speaker stereo system. Sound image

positioned at the center does not move at all, and music instruments and sound positioned to left and right surround listeners. The

surround stage can be created, exceeding location of two speakers. Real three-dimensional sound field can be created by ambience

sound. Listeners feel as if no speakers exist.

• Type D Spatializer (Directional Positioning)

It can position or shift the individual sound source along 270˚ arc in real time for example at game play or reproduction. →The

AN7395K and AN7395S can support almost infinitive number of inputs. They require only the function panning these signals

between L and R. These ICs can be easily incorporated in the video game machine or sound board of computer and thereby the

sound source can be controlled in three dimensions without DSP.

• Type S Spatializer (Spatial Synthesis)

Though almost all the sound of computer, video game or multi-media uses mono-source, playback is often performed by the

stereo unit. The spatializer can give the mono-source profoundness and realism, providing the natural and comfortable pseudo

stereo effect.
