    [HELP]Dual Channel InfraRed Wireless Headphone Design

    The project is Dual Channel IR headphone, whose carrier is 2.3/2.8Mhz and 3.2/3.6Mhz (A/B switchable)
    Can anyone have some experience in such headphone circuit?

    I had try to use TOSHIBA TA2056FN (2.3/2.8Mhz IR receiver), and MC3361 or KA22425 such FM/AM chip to finish demo sample.
    But there is serious CrossTalk problem between A/B channel.

    If you have some information about such project, pls contact me via the following box:
    surfingyee@21cn.com

    Thanks

    You may be having IMD problems from overloading your IR receivers with strong signals.
