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

MARANTZ MA 700 NOT SURE HOW TO MAKE CONNECTIONS. NO MANUEL. LIGHTS UP


you'll want to use the rca sub out from your pioneer, to almost any input (aux, tape, cd) of the marantz, then speaker cable from marantz to sub. once you get them hooked up, adjust volume, bass, on the marantz to blend well with main speakers at a nominal lvl,

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.

After listening for awhile the volume will automatically cut to a lower level, then iuse the remote to turn up to correct. does this sound like dirty contacts?


I would thought no. Generally you would only get that effect if you had moved the control yourself. Many amps now use a IC for volume control. That could be playing up. It could be a dry joint, if the sound effects some movement in the unit, but it seems unlikely.

Marantz SR9200 shuts off intermittently while watching or listining.


Check all speaker connections. unplug everything.. start with just L and R speakers. Do a mic calibration..also check all your source inputs to the amp. start from the basics. Is the amp still under factory warranty? I used to install marantz...also make sure unit is well ventilated. IF you are using audio zones in your place..with in wall volume controls..make sure they are impedance matched. VOLUME may be set to high...overdriving the outputs..eventhough audio may not be loud. Set volume to -30...?

Marantz sr18ex clicks on and off while watching dvds.


I'm not familiar with Marantz receivers but sounds like it could be intentionally cutting out either because it's overheating or it's afraid it might blow your speakers. Two basic things to try:

1) Leave it off for a few hours
2) Turn the volume way down so you can just hear it - not sure if the cutout is intelligent enough to take this into account but worth trying...

Also, any chance you have it in a closet or cabinet without adequate ventilation? Does the area where it's sitting seem especially warm? If you don't have enough air movement then overheating is far more likely.

Good luck!

Loss of volume on left channel


Marantz SR 5200/6200 lost audio or crackling on left or right channel except in mode s-direct is now fixed !
The root cause is a defective inegrated circuit on DSP board (the one with digital inputs). To fix it change the chip CS4391 by a new one or better by the improved version CS4392. On my device a capacitor was cut close to this IC : replace one 1uF after changing the IC. For any question search me with my callsing "F5RCT"; i have a spare IC for the one who is able to change it !
I'm amateur radio and engineer
