DIY Surround Sound Dock for Apple iPods and iPhones

This is a "quick design" to make surround sound dock for Apple iPod, iPhone and iPad devices. This audio docking module contains analog surround sound processor, bass booster and electronic mode switch.

Main components of this surround sound dock are LA2610 - analog surround sound processor and ATTiny13 - 8bit MCU. This unit is design to work with 9V external DC power supply and it can deliver maximum of 2 × 1W audio output power.

In prototyping stage we test this system with couple of Apple iPod and iPad devices with 4inch full range 8Ω speakers. This system can also drive professional headphone through its "Ext. Output" connector. This system need 160mm × 100mm double side PCB and it is specifically design for vertical docking chassis.
