Cambridge Audio Azur 640P

The best connection from my 640p to my 840A v2 amp

  • Anonymous Mar 15, 2014

    Hi! I have just had my Azur 840A amp back from the repair shop to replace the standby PSU which was damaged in transit. Now, when I turn the amp on, the LED readout says SPEAKER CHECK. Then SPEAKER ON for a split second. Then CLIPPING. This is without any music actually playing. If I disable clipping then the amp is only working through the left speaker out. Any ideas? All best wishes, Nic

Azur 840A Clipping


CLIPPING occurs when the level of sound is way too high.
Try changing the speaker-wires -- you may have a short-circuit someplace in the wires that is causing "feedback".

Cambridge audio azur 840a volume control problems


The volume control is a resistor ladder controlled by software. If powering off the unit for an hour doesn't fix it, I would imagine that one of the "steps" has a problem. Contact your dealer or visit http://support.cambridgeaudio.com/.

Just make certain that the connections are all good with no wires touching. If it still doesn't perform after that return it to where you bought it and get a new replacement or your money back.

I use an azur intregrated amp 540A and a Azur Pre amp 640P. When first power up, The amp makes a popping sound and the volume turns down. Some times it can pop 2 or 3 times within a few minutes. Then it...


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!

Display fading on AZUR 840A


Did you take the time to fill out the Warrenty Card? It's VERY important that you do when you buy ANYTHING, especially electronics. Call the store where you bought it. Ask them if they can track it (the sale) If it can be fixed under warranty, be prepared to have to ship it back to the manufacturer.

My Cambridge azur 540C compact disc player won't read CDs.


Hi...

After about 100 CD-DVD units, I've found that most problems are from debris/film on the laser lens.
If taking the cover off the unit doesnt scare you, unplug it and blow out the CD assembly with a can of compressed CO2
and VERY lightly clean the laser lens with 91% or better alcohol on a cotton swab.
If that doesnt work , contact Cambridge Audio for a repair service.
