could some1 tell me how to couple ic audio amps....i want to use it as a guitar amp.. i have couple of ic amp boards lyin around which says 40W!!!... along with pre-amps.. i think it has d potential to give really good distortion  (with lots f noise actually)... |

Guitar in mic input=bad idea. I tried in my studio...it didn't go well. It sounds like crap. Invest in a decent rocktron gainiac guitar preamp. |

A mic preamp with a low input impedance is not good for a guitar pickup that needs a preamp with at least 1M input impedance. Many high input impedance guitar preamps have a voltage gain of only 3. A mic preamp has a voltage gain of 50. |

Maybe your guitar needs a pre amplifier before plugging it to
your amplifier.See if you could hear it louder when you plug it
to an amplifier with a mic input if its louder then you definitely
need a pre amp. |

If you want more gain then just play louder or turn up the amp's volume control.
when an amplifier reaches its max rated output power then if the input is turned up the amplifier has severe clipping distortion. The resulting square-waves have twice as much power (a little louder) than the amp at its max undistorted power.
If the input impedance of your amp is too low so that it loads down your guitar's pickup then you need a preamp with a high input impedance. Then the main amp will have a higher input level so that it can reach its max output power easier. |

thnx for d reply...
i mean in series... i tried it wid capacitors and pots in between but d output jus goes low after a second at the output of the 2nd amp... since it is to b used as a guitar amp,distortion is not a problem... is it possible to get a gain that is product of the seperate gains of the amps?(as in low power transistor amplifiers)... |

What do you want to couple??
Usually, you can't connect the ouputs of amplifiers in parallel. If it was possible then the output power to a speaker will be the same as one amplifier.
The output power of amplifiers is exaggerated. A 40W amp might produce 40 Whats but only 4 Watts. |
