Cambridge Audio DacMagic Plus Questions & Answers
Caimbridge audio amp right channel always dies
Stereo amps are two mono amps put together. So if you have a bad channel then you also have a good channel to compare it with. I suspect you have a faulty transistor. You can test it by proding the channels with a pen or your finger - touching plastic only parts. The two channels should buzz. If buzzs in the left then if you touch it in the right it should do the same. An alteration or change in the sound in the right and you have found the faulty part.It's nothing to do with the power supply section so keep away from that!
DC error Cambridge audio amplifier
For model AZUR 740A with random DC-error on display after power on.
Only several resets will be a solution, but not for long !!
Behind the rear panel is a small pcb with 2 relays
which switch the transformer AC output to the rectifiers of each amp channel
Relays are branded " MASSUSE", type ME-11,with a 12VDC coil,
contacts 8A / 250VAC
They are DPDT type.( double pole double throw)
Contacts will detoriate ( burned) after several years.
Replacing these relays by a good model ( Schrack i.e.) will be the final solution to
get rid of the DC-error problem and will save your speakers !!
The pcb can be removed without disassemling the rear cover, only the top cover is enough, but this is with very tiny TORX screws.You need a very small fitting tool.
How to wire my speaker to my amp
The speakers may have plugs that are compatible with sockets in the rear of the ampm if they are compatible it is a simple matter of inserting the pins and pushing them home.
It may be that the speakers just have bare wires and the amp has spring loaded wire retainers ...in that case you will acertain which of the speaker wires is negative and which is positive and , while pushing down the spring loaded clamp of the speaker wire retaining clamp, you should insert the appropriate wire in the
appropriate hole and release the catch
as a matter of interest what are the makes and models of amp and speakers?
Why does my Cambridge Audio Azur 851W power down even when a signal is operating.
amps like this only power down when there is a problem with the amp, usually a shorted output stage, but could also be shorted speaker wires or damaged speakers, it's a self protection mechanism
do you get sound from both speakers before it powers down?? if you do it is definitely an internal problem so take it to a repair facility,,,
if not check the speaker cables & the speakers themselve
