Marantz SR5600 receiver troubleshooting.

I was adjusting the m speaker b source. while i was turning through the various sources, a message "protect" displayed on the front of the amplifier, and now no lights show on the front. The amplifier still works, but I am not able to view the display. The manual just says to call for servicing. Can you help?

Ya, it sound like you just blowed the output on one of the stages, I would disconect the speakers to see if the problem still is there, second open the top cover, there should be about 7 fuses check for a blowed one, last hope it's not an output, if you never worked on an amp, you will cause more problem.
Hope this help

I have a Marantz turntable, a Marantz CD player, an Eltax tape player and a Marantz amplifier with two Cambridge speakers, how do I assemble them into a stack system please ? Thank you


All the sources, turntable, CD player and tape unit have an output. These should go in the input of the amplifier with the same name. Then only the Tape player, could have an input, for recording music or whatever. For that input, your amplifier should have an tape out. All these should be connected with cables with tulip plugs, like these.

Use the white for left on everything and red for right.
If one of the devices as a different connector, find a cable for audio, with on one end the tulip plugs and on the other end the fitting plug.
Then the output of the power amplifier it should say output or LS, can be connected with 2 wires going to the speakers.
For this the same counts, although it is difficult to see when you use electrical wires in one colour. What comes out red on he amp, should go on the same screw connector on the speaker. Just to avoid one speaker being out of phase. It will work, but could sound a little strange when the speakers are out of phase.
With the correct model names added, perhaps we could have given a more accurate answer.

Success.
Please don't test the system or switch on, with the volume button to the max. Don't switch anything on an amplifier when the volume is high, or the setting is high. A short increase of the volume, during switching can, and has very often destroy(ed) the speakers.

How to troubleshoot a kenwood kr 5600


These older tuner/amps have protection relays that when latching, are distinctly audible. Does the relay engage after approx. 10 seconds after turn-on? If not, check your speaker wires and/or speakers for issues. With all speakers (and wires) disconnected, the relay should still latch after turn-on. If not then you have an internal problem...likely a older pre-drive transistor that's bias is incorrect, which in turn causes bigger problems downstream.

I disagree without a source this is what you would get, no sound.
Contact the manufacturer or try an on line search with Google!

Left channel static


I have seen dirty switches or pots cause constant static. I would get some contact cleaner and try spraying it into all switches and pots, and work them to clean the contacts. Also, check to see if there is static in a low-level output such as the one for a tape recorder.

Protection circuit operates when CD is played


are you playing a cd which you recorded at a higher level? if so, you are overdriving the amp. you may want to check some of the setup menu items which could contribute to this. it also could be caused by a driver or component in a speaker which is getting maxxed out, which is easier to do with the cd source than any other in some cases. denon protection circuits are quite sensitive. good luck

Marantz Pm-7200 left channel weak compared to the right


hmmm. Let's start by swapping the wires you are using for your speakers. Double check the wire connections first, then take the left and place iton the right and vice versa.

Dear Sushant,    I do not think your use of an equalizer has caused any problems.  I will explain the proper use of the source/direct button.  This button's function is to monitor the output of a recorder connected to the record outputs of your amp.  When this button is pressed on the sound going to the speakers comes direct from the "source" (cd, radio tuner, phonograph etc.) when in the off position you can monitor the recording of whatever source is being recorded via the tape deck.  This switch must be off to record through the amps record outputs.    To test this, put a blank tape in the tape deck, choose the source as phono and place the dec in record/pause.  With the source direct button pressed on you should hear a change in volume when moving the amp's volume knob only.  When source direct is off you will be able to hear the output of the tape deck, so adjusting the tape deck's record level will also affect the volume coming out of the speakers.  more record level in/ more level out.!    Below is copied from page 9 of your user operation manual for Marantz's explanation of the source/direct button.  image.tiff
best of wishes, Michael Mittelsdorf

Marantz SR5600 Problem


HI...

From others I've worked on it appears that some solder joints on the volume control assby have "let go".
There are a few places that stock Marantz parts online.
Typically ,this isnt a consumer serviceable issue.
I can possibly suggest a repair place depending on where you are.

Hope that helps.

Protection snaps into action intermittently


I don't think the pin or third prong on your power cord would be the problem, but I would make sure that all of your speaker wires and connections going to your amp are not shorting out against eachother.


I hope this helps you out.
