Hi, Could you nice people suggest a good voltage controlled amp chip (audio) for 4 channels or a matrix switcher with cross point attenuation 9 (chip). This is to be used with a 16f84. I think it is obvious what I am trying to achieve if anyone has another way of attenuating 4 channels of audio (with 2 channels that can be swiched to Mic level) please let me know. Thanks in advance Mathew Cohen
