Marantz PM4000 amp keeps cutting out

My amp works perfectly but when it starts to reach above average volume it cuts out to mute and will only work when i turn it off and on again before cutting again when reaching that same volume. My speakers and CD player both work prefectly when tested with another amp. Is this repairable?

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.

The converter should not b e a problem. It's time to ask a technician or a HiFi shop, an internal short circuit is blowing the fuse. Don't insist.

Marantz pm 7200 loudspeakers do not cut off when headphones pugged in

Some amps have a button which you press to mute the speakers when the headphones are plugged in. Sometimes marked "Speakers on off". If it hasn't then a new headphone socket would not be expensive to fit. As long as the amp producers sound I don't see any future problems. The previous owner may have used the headphone socket a lot, and simply wore it out!

Amplifier works at low volume levels. When volume is turned up it cuts out for a few seconds then there is a click and it comes back on and then cuts out again until the volume is returned to a low...

Try looking at the rear of the amplifier to see what the speaker load should will be measured in will then want to look at the speakers to see what the impedance is on the speakers...if it is LOWER than what is on the back of the amplifier, then you have an impedance mismatch which is causing the amp to go into protect... If the speakers are in fact the proper impedance then you probably have a bad can test this out by disconnecting one speaker and trying it,,,and then the other and so on...another thing to try would be to obtain another pair of speakers with the proper impedance to see if they if you try all this and the amp still cuts out..them there probably is a problem inside the amp...I specialize in Vintage Audio so try these things first...if you have questions feel free to email at

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.

Hi I have two marantz amps witch cut in and out when run from

In stereo terms your system is "clipping" which means you are pulling more amps than the system can handle. If it happens only when you use the mixer, I'm thinking the mixer cant handle the power. Check the specs, It should show maximum amp input.

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
