Speakers will only be connecgted to the external power amp., a Parasound Halo A21. The speakers will be Magnepan Mg 3.7's. Under these conditions will the entire voltage output of the Cambridge(excess of one volt) be directed to the Parasound with no voltage directed to the unused (no speakers connected) amp. section of the Cambridge integrated?
SOURCE: can't connect amp to speakers
Hi look at the end of speaker terminals, you will find tiny plastic caps , get a small screwdriver toease them out, you can plug banana clips straight in as I have done.Hope this helps
SOURCE: I have cambridge audio azur 640a amp. Problem I
The fault is on the amp! It sounds like the protection circuit is detecting a surge on the channel and shuts it down to protect the speaker. I would check the semiconductor device(s) for the right channel on the heatsink of the amp. You might even see damage of burning on one!
SOURCE: I use an azur intregrated amp 540A and a Azur Pre
I've never repaired one of these but I have an amp at home that makes a intermittent static "popping" noise that i'm going to put down to a dirty volume pot (control) that needs cleaning. I will also have to change some of the electro capacitors that have dried up inside which cause "shot noise". With the right lubricant (electrical contact cleaner, nothing else) you could take to lid off and spray a small 1 second blast into the hole of the pot and any other balance or tone control yourself but I would take it to the electronics repairer to get the capacitors checked over.
My theory only
Good Luck!
SOURCE: HI, Can the Cambridge Audio 640a integrated amp
Of course, just run an audio RCA pair out from the Pre Out to your next amp and any input. All control for volume, tone, etc will remain with the 640A.
