Start with reset(power off and then power on)-if you see power light on-check your input source(mic or dvd or other)-check your speaker cables for short or open circuit after that check speaker itself-if you confirm that all outside amp is ok.and still not working you will have a problem in amp internal circuit.(if you have speakers button in your amp do not forget to press it.)

I have a Marantz turtntable, a Marantz CD player, an Eltax tape player and a Marantz amplifier with two Cambridge speakers, how do I wire them up please.


If you have a pure amplifier, there may only be one set of inputs, and one or two pairs of speaker outputs. The inputs are probably RCA plugs. Connect the CD or tape player to these. The speaker outputs are typically heavier binding posts or wire clamps. Each speaker should have one pair of wires. One for the 'Red' post, another for the 'Black' post.

If you have a 'Receiver' you will have several inputs to use and switches in front to select them. The CD and tape can be plugged into either tape, CD, or Aux inputs. (Not 'Phono') The speakers hookup is the same as for the amplifier.

You may also want to google the make-model of your amp to find a manual....

Cambridge azur 650R shows "PROTECT" after Volume more than 1/4, protection-relay works, loudspeakers&cable are o.k, WHY?/Solution (relay broken)?


What ohm rating does the receiver have and what ohm speakers are you connecting. If the receiver is rated for 8 ohm speakers and you are connecting 4 ohm speakers, you are overdriving the amplifier. This will cause the protection to trip. Also make sure your speakers polarity are matched. If they are out of phase this may also cause a problem.

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.

Connected new polks to cambridge audio amp a1 (about 30 watts per channel) and play cds through a panasonic dvd/cd player, but i can't turn up volume past 1 without it sounding too loud. sound is ok, but...


Plug the player in somewhere else besides the PHONO input.

"PHONO" is the only designated connection on an audio device that is literal and exclusive. Nothing but PHONO will work right on it because old-school turntables require it to preamplify the tiny current produced by a Phono cartridge.

I imagine if you REALLY listened hard to the result you have you would find the bass is WAY too.

Google 'RIAA curve' to understand why.

"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.

Sony STR-DH510 Multi-channel AV receiver connected to cambridge soundworks ensemble IV w/ passive subwoofer: no sound from center channel during viewing, or during speaker level test- all other speakers...


The STR directs sound to the center as instructed by its speaker setup. You say the center does not work on calibration. Is it defined?

Prove another speaker does or does not work on the center output. Then we'll know if it's the receiver or the speaker ensemble that has the problem.

Have you checked the manual for this "
There is no sound, or only a very low-level sound is heard from the center/ surround. "?

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 ;)

HI,all you need to do is hook up the optical out put to the optical in on the amp this will give you the best sound, also try phono out of media centre if you have it as this has a higher band width.

HOPE THIS HELPS.
