    Hi All,

    I am making a head phone amplifier with input coming from an electret mic.

    My problem is using the standard data sheet circuit i get very low gain that too only when i hold the mic verrry close to my mouth.

    How to get more gain???

    pls help

    regards,

    Ashok Shenoy.

    You must talk louder;) Joking aside the gain is fixed. So you must add a microphone preamp stage.
