Cambridge Audio 540R Azur V1- Automatic DSP change

Hi folks, I'll be using the AV receiver in subject for a couple of days now. The problem with it is that it changes DSP mode automatically. I've got just two speakers so I set it to play "Stereo" but the every few minutes it changes the configuration to "CINEMA" or "MUSIC" DSP profile . This is particularly annoying because the CINEMA profile send all mid freqs to the centre speaker that I don't have! I've opened the beast and there isn't anything "clearly" wrong with it. Any idea how to proceed? I tried the DIY approach because the unit is out of warranty and I bought it second hand. Cheers Marco

Cambridge Audio Azur 640R AV Recorder won't switch off


Sounds like the unit is victim of a power surge. The power control board is probably damaged. You will be better off replacing the amp as having it repaired will cost more than replacing it.

I am using an optical cable to from my Panasonic Blu-Ray player to my Cambridge Audio Azur 340R receivable, and the centre speaker is not working


In any 'connection' question there are at least two participants and specific answers require specific details about all components in the path.

Does the center speaker work for just speaker testing? Your unidentified BluRa player has to know there's a Center Speaker, too.

Digital bitstreams don't arbitrarily drop out one channel.

"SW" stands for SubWoofer.

Page 8...

Shows the currently active channels depending on decoding mode and source material. Icons lit indicate active channels in the source material. Icons with a box around them indicate actual channels being output separately.



Search for the word "balance". Page 8 again (circled 8)...


Lights when the Front Left and Right speaker outputs have been set to different levels in the OSD, i.e. a balance adjustment has been made.

You can look at the relative levels of all channels as described on Page 14.

I have an onkyo tx-sv444 receiver that the word protect comes across the screen and then shuts off what should i do about it


When the word protect shows up it means trouble. The circuit that shows the warning and shuts the unit from working has detected a short somewhere in the unit. More than likely one of the output transistors but not always. Have you had a power failure lately? Lightning strike? Power bump? If so the problem could be in the Low Voltage power supply. First unplug the unit. Take the bottom off if it has a panel which can be removed separate from the complete bottom. Under the panel should be the output transistors. Check to see if any are shorted with a DMM. If you find any they will need to be replaced. If you do not find any you will probably need a competent tech to troubleshoot the unit. Let me know if you need anymore help.

Protection overload and the system shuts off


Reasons: 1. Short in the wire, speaker, or amplifier 2. Amplifier malfunction 3. Overload of the amplifier 4. Overload of the speaker
Listening to audio at loud levels requires more power obviously. But the speakers and amplifier may not be rated or capable to handle it due to age or design.

Protection overload and the system shuts off


check your speaker wires for short, try to turn it on without speakers connected, if all connections and speakers seem ok the problem is internal witch can go from blown power supply to shorted output devices and everything in between , and as always look for repair shop in your area, do not attempt to do it yourself, fire hazard and electric shock are the things we all want to avoid ;)
