Checa las bocinas puede que no soporten la potencia del amplificador y por eso se protege.

Pm 7000 marantz cuts out when I turn up the volume. Works well at lower volumes... tried other speakers and no issue? Is there a way to check the receiver itself?


If the device works on other speakers then it is probably working as it should. You need to check if the is an issue with the speakers that cause it to cut out. Make certain they are the right Ohms for the Marantz. Check the connections to them. It could be that a safety device is clicking in to protect them amp due to some overload problem, caused by the speakers themselves. It might even be one speaker that is playing up. Try testing one speaker at a time, by not having the other connected and the balance control only to the one connected.

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.

Marantz problems


The speakers are 8ohms. Always try using speakers 6 or 4ohms. For B&W 683 on PM 6004 is too low. You should go for PM 7000 or 8000 series to catchup with 683. Also when you increase the volume please decrease the bass as well.
You need 8ohm 55w to 90w or 4ohm 80w to 110w speakers.

Hi Strange problem with Marantz pm7001 When ever I turn the volume upto around 1/3 and 1/2 of the way, the amp cuts out and reset it self down to minimum volume. It seems like the amp ins't enough power...


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.

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.
