Agamem Microelectronics Inc. PRELIMINARY AA8335 SOUND EFFECT PROCESSOR ■ DESCRIPTION Made by Bipolar devices, AA8335 is a sound effect processor, applying for products like LCD TV, home theater, PC, notebook and car stereo. We apply the QEQ technologies such as “phase conversion” and “delay compensation”. Except for “clear and crystal” tone quality the main feature of the “play back” sound effect consists in powerful bass whereas a fine treble. Note 1: QEQ® is sound effect technology owned by QSound Labs, Inc... Note 2: Agamem has got licensing agreement of QEQ® from QSound Labs, Inc... ■ FEATURES •Simple External Circuit • Operation Voltage : (4.5 V ~ 13V) • Independent two sections of controlling switch: High Band( 6dB or 9dB)，Low Band( 6dB or 9dB) • Bypass : (0dB SEP_OFF) • Package Outline : PDIP20L, TSSOP20L ■ APPLICATIONS • Sound effect processor for LCD TV, home theater, PC, notebook and car stereo. ■ BLOCK DIAGRAM ©Copyright Agamem Microelectronics Inc. 1 www.agamem.com.tw 2008/3/26 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
