It creates a stereo image with depth in three dimensions from ordinary left and right input channels. The patented QXpander (*1) technology developed by QSound Labs, Inc., is faithfully implemented by Agamem(*2). Note 1: QXpander® is a stereo to 3D enhancement processor and is a trademark of QSound Labs, Inc... Note 2: Agamem has got licensing agreement of QXpander® from QSound Labs, Inc... ■ FEATURES

• Sound spreading can be easily adjusted using an external VR.
• Few external components required through use of internal filter circuit.
• QXpander on/off switching at TTL level. ■ APPLICATIONS
• Sound enhancement processor for LCD TV, home theater, PC, notebook and car stereo. ■ BLOCK DIAGRAM 16 1415 13 1112 910 1 32 4 65 87 RIN VREF S/3D FC SPC 3DIN ROUT GND Vcc LIN 3DF1 DET LOUT 3DF2 3DF3 3DF4 AA8334

Note 6: Input current of BYP terminal (pin 3) (Vbyp=0v) Note 7: The mute signal which switches off the power supply of a power amplifier that is connected with AA8334 appears in the 10 terminal. When the power supply of AA8334 is switched off, the pop noise occurs. We recommend muting the pop noise. The way is that the power supply of AA8334 is switched off after the power supply of the follow power amplifier is switched off. Vcc=8V Vdet1 Vcc=0V Vdeth Vcc waveform (Pin 16) ←Tvoff→ DET pin waveform (Pin 10) Note 8: We recommend using the regulator for the power supply which occurs the ripple. Note 9: When the signal is input in ZLIN, it is the ratio of pin 7 output voltage to pin 9 output voltage. Note 10: When the signal is input in ZRIN, it is the ratio of pin 9 output voltage to pin 7 output voltage.
