Thai will require removal of the top cover to move jumpers or program dip switches in proper order. This will be explained in the owners manual which is located at Krells web site.

This confirms you have an earth loop problem then. Has it just started, or has it been this way from when you first set up the gear?

SOURCE: I need to connect a

You will need to use the pre-outs on the receiver to hook up your amplifier. I am trying to verify if that model even has pre-outs for the front channels, many do. You will be able to tell quicker than I can by just looking for outputs labeled pre-out for the front channels. Just use the cables you have to attach the Krell amp to those pre-outs and you will be good to go. Let me know if you are unable to locate them... the receiver may not be designed to do that..

You are overloading your amp. IMO 640A cannot handle heavy loads.

Better change the speaker combo and connect something that puts right load on the 640A. Else, get a meaty amp from CA.

Where can I get a fuse for my Krell KSA 300 amplifier.I had a blown fuse on the left channel.


Fuses rarely go on their own. The cause is likely to be a shorted semiconductor device in the left channel output.
Fuses are generally not specific to any brand. Is the fuse a tube with metal ends? If it is measure the length in MM. Then look at the end and you should see the rating. Either in A for Amps or MA for milliamps.
Any electronic parts supplier should have the one you want in stock. Buy several, for if the part I mentioned has gone, it will blow again.

Crackling noise all channel when i change 110v to 220v


Sound as if you have a low voltage, check for 220 v if its ok, then you have a current problem, the higher the voltage, it will be less current flow. Hope its not a flaw on the 220 v side

Will the amp play 2 ohm speakers


If your amp has ability to play 2ohms, then it will play. It will play even it dosn't have the provision. It might cause damage to the audio output at certain level if volume level is increased. My advice is to check your amp. or read the user mannual for perfact usage. Thanks

Hello, after plugging on Ipod through my preamp hooked through my krell kav 300 integrated amp I heard a super loud noise and lost power. I examined the fuse and it looks fine. What do I do?


Sounds like the volume was way up when the iPod turned on. iPods are DC and cause a sudden thump through the speakers when they power on.
If the fuse is not blown, there may be another fuse you have not seen. Most amps have three to five fuses especially a 150watt/channel like the Krell.

Xm-2002gtr amp keeps kicking protect light on


check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop

Krell kav300i, increasing volume by itself.


That is an extremely odd problem. I suggest finding a tech in your area who is familiar with the unit, or contacting krell directly.
