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

How do I activate the component out on the Marantz SR 6007?


You need to go to Menu/Input Setup/Input Assign. In the column labeled COMP, assign the Component Inputs (1-RCA through 4-RCA) to the various Sources.

You may need to go to each Source and turn Video Convert to On. Select an Input, such as SAT. Go to Menu/Input Setup/Video/Video Convert and select On.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Marantz 4220 Power Switch Dear experts Some time ago when unit switched on cracking noises in speakers started. But now exept ligting up no sound is comming just little when volume turned up.What could...


The Amplifier was failing and that's why you were getting the crackling noise.

Most receivers have an Auto Protect that shuts the system down and goes into Protect mode at the first signs of failure or overheating, usually indication by 'Protect' on the display.

I'm presuming from your post that you never got any indication that the unit was shutting down to protect itself and has just failed, so I'm presuming that this facility isn't fitted on this model.

Depending on you Technical ability it could be an easy repair (replacing the complete PCB or some PCB components). Your only other solution is a visit to a service engineer.

Protect error on marantz sr4200


Check all your speaker wires carefully. Chances are good that a braid has crossed from + to - and causes the unit to protect itself. This is a very common problem! everyone's done it at some point. Check connections at both the receiver side and the speaker side. If you still have a problem, post a comment and I can help you troubleshoot further. Hope this helps.

I have a Russound CAV6.6 Rnet controller. The controller will turn on, but I can get any sound out of the speakers. It used to work just fine. Now the lights come on, but no sound from the speakers. I took...


Have you changed any connections behind the CAV recently? This happened to an associate of mine once and it just turned out to be something simple. This may or may not be the situation in your case. Check to make sure your source audio cables are connected to the correct source number that you assigned in the programming (Ex. AM/FM Tuner = Source 1). Also make sure your audio cable is connected to Source 1 IN (and not the "OUT").

Narrow down the source of the problem:

Make sure the keypad you are using to test the CAV is not in "Mute" mode. Press the "Pause" button to engage/disengage from mute.

To further troubleshoot your issue if the above is not the case you want to use a device (such as an ipod tthat you are sure the audio output is working using a stereo mini to red and white rca cable) and plug into each source input (one at a time) behind the Cav then monitor that source# on the keypad to see if you hear the ipod on any of the sources. If you hear the ipod playing on some sources and not others it obviously means some of your source inputs are having problems and the unit needs to be shipped to Russound for repair.


Make sure the front of the Cav6.6 has the proper colored lights lit up. When no keypads are on the zone should show red, when a keypad is off the color should be green for that zone, if there is a short circuit with the speaker wire the CAV might be in protection mode and the color might show orange.

Hope this helps.

Marantz sr6200 problem


I think it may be related to set up of crossover frequencies within 'menu'. There's a menu where speaker sizes are set, as far as I remember the lowest setting suggested crossower freq for sub somewhere at 80hz as default which may be too high of you have sub.
