What's probably happening is that the amplifier is shutting down or cutting back the volume as protection from damage. You may have a partial short in the speaker wiring that is not a problem at lower levels, but at higher ones causes the amp to see too low a load. There may a problem with a speaker or crossover component that is breaking down at higher volumes. Or something in the amp's output stage is unable to handle the load.

Test the system with a known good speaker system and length of wire and see if the trouble continues. If it does, you'll know it's the amplifier that needs to be checked. If the test speakers can reach normal volume, you can start checking the wiring and other speakers for the source of the trouble.

Hi the problem with my marantz sr770 amp is when I rise the volume the sound cut off & it make a sound like (tic-tic) inside,so pls help me!!!


It sounds like a shorted speaker or to many on one channel. It could also be a failed output device. I think the tic-tic is the overload safety cycling.

Hii I have sony shake 6D system and whenever I turn the volume up it reaches upto 40 and shows the error of 'protect E01' while the maximum volume is 50. Please help


Most likely, your unit is shutting down due to overheating. You cannot run an amp at that kind of volume very long. It is shutting down to protect itself. Try running the amp at 1/3 your normal level. Most likely, it will not shut down.

Hi can I hook up my marantz mm500u amp to my pioneer 305 vsx audio reciever


I presume you just want to slave the Marantz to play whatever the Pioneer is playing.

Run a pair of RCA cables from either the Pioneer Tape Monitor REC or the VCR/Tape 1 Out jacks to the desired Marantz Input jacks. DON'T activate the corresponding switch on the Pioneer.

Only the basic Leftand Right channel programming that the Pioneer plays will be available at the Marantz. You will NOT have centralized volume control at the Pioneer.

I have a marantz sr4320 receiver. The volume control knob is not working---I can't get any sound no matter the volume number. "d8" is now showing, too, following the number. I have followed...


Do you mean "db"?

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING. The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Turn the volume down.

While you're squinting at the front panel, find the manual and evaluate every indicator on the face to make sure you understand what they mean and how they might affect operations. Look for Speakers NOT enabled, Muting ON, a Tape or other input inadvertantly selected. If you fail to find the errant setting, treat it like a new install and set it up all over again according to the manual.

Hi, My Marantz SR4200 goes into protect mode about 45min after cranking the volume up to party mode, ie above '0'. It is getting worse slowly. Ok at lower volumes. Something seems to be overheating,...


Or it could be you're overdriving it, hence the heat. Take a clue and turn it down. At 70 wpc played loudly it could be going into speaker- and self-damaging distortion.

Make sure it has a lot of ventilation.

Mute function on the amp


A couple of questions to try and narrow this down:

1) What is the impedence rating for the speakers?

2) When the unit shuts down, will it recover on its own after a little while or do you need to power cycle it to get it to work again?

3) When the unit shuts down, is it hot?

Possible causes of this behavior:

1) Impedence rating too low causing the amp to work too hard and shutdown.

2) Excessive heat (caused by #1?) will shutdown the unit to prevent damage.

3) Possible intermittant short in the speaker wires somewhere? Loose connection?

A little more investigation will be required to find this. A repair shop would run this unit under load and monitor the outputs for heat and any spikes in the signal that could kick in the protection circuits.

Keep us posted on what you find.

Amplifier power cutting out


not enough power to amp and or amps location is too hot might want to invest in a couple cooling fans from computer store and attach where needed

an amp should take up to 3/4 load but when not enough air to it to cool it off it will shut down

try this turn gain all the way down and slowly work up too desired amp volume setting
