xcanv3 crispy sound
Hello,
I've got a pair of HD-650 Sennheiser headphones and a Music Fidelity X- CAN v3. It's the first time I connect them, and I'm hearing crispy noise all the time especially at the left side. What's that? It's something to do with the tubes warm-up? or should I connect to ground or smth. please help! thanks! |

Is there some kind of sensitivity mismatch in your total setup that causes preamplifier-type noise to be more audible than it ought to be? Kind regards Peter Larsen |

So perform the usual differential diagnosis drill... Do you hear the noise with no connection between the laptop and the XCanV3? What does that tell you about the source of the noise and/or distortion? |

Happy soldering .... 12 dB attenuation will probably do just fine for a first attempt, but you may need more so as to prevent some idiotic beep from causing temporary deafness. One known source of idiotic beeps is the windows mixer application in this here xp-thingy, YES with system sounds OFF it will beep at 0 dB FS when volume is adjusted. Microsoft sure knows best .... Kind regards Peter Larsen |

Hi Al,
All of the stuff below probably voided by the fact that the xcanv3 does have a volume control.
