Question about Marantz Audio Players & Recorders

Open Question

I have a Marantz SR-96 THX receiver, which sounded powerful and sweet up until 6 months ago. The right front channel now sounds crackly & scratchy in the mid-high area... I nearly replaced my whole front audio speakers but, I tried another amp from a mate and they sounded great again. So the problem points to the right output stage. Is it the caps or pre-amps? or something else.?

SOURCE: no audio output - Marantz 2238

This can be as simple as a poor connection somwhere in the voltage regulator circuit or a defective driver transistor or output transistor. In any case, this is a simple repair for any shop that works on vintage receivers. If it is the outputs, that will be the most expensive repair from a parts perspective. The outputs will cost in the $5-$10 range for each one and it could be 2-4 pieces. If you wish to attempt this repair yourself, you will need a multimeter that has a diode checker. Let me know and I'll provide additional details and instructions.

SOURCE: Pioneer audio receiver pre-amp output

It is possible then that the root cause may not be electrical, but acoustic if you're noticing the issue from your listening position.
If you can run a channel test signal identically one channel at a time by positioning your meter less than a foot away and exactly the same distance with each speaker and the level differs by more than 1/2dB, then it's not the acoustics.

I am not getting sound from the marantz 5009 receiver to the tv. I am using hdmi cables from receiver to the tv


Huh? why? would you not want to get sound from the lousy TV speaker to the receiver and it speakers instead? That's how I have my Onkyo THX system set-up. My Samsung TV actually has decent speakers but even they are junk compared to a real speaker system. Even $500 worth of real speakers can sound better then the speakers on a $5000 TV. Do not do it.

Marantz SR-18 NO Sound No Data error for DSS (Directv) only


You need to check the connection of the lead that carries the audio from the DSS to the amp, move it to one of the other channels ie vcr and see if it can be heard when set to and switched to vcr. Then we know if we are dealing with the Amp or the source..

I want to connect my bravia lcd to my marantz sr770 i can only get two chanel sound from my two front spearker i cant get the surround working


Let's break this into little pieces. Disregarding the TV, does the Marantz otherwise provide multichannel sound?

How is the TV-related audio getting into the Marantz? Analog RCA yields only 2-channel audio.

Two front speakers are only capable of two channel sound.

What would work better for Marantz SR 4200 Apple Composite or component cable? In order to play music through the amp as well as watching videos


Component Video is a big step up the food chain in quality. Component Video inputs are for video only, not for audio. I don't see Component Video inputs on the Marantz SR-4200; only Composite and S-Video. S-video would be a step up from Composite and it carries analog stereo sound.

You don't give any clues as to the source's audio capabilities.

Digital Audio of either flavor is preferable. Grab the best possible TV-related audio from your Cable/Satellite box to the Marantz and run a pair of RCA audio cables to your TV just in case you want to watch the weather channel without hi-fi sound.

Center channel goes muffled after a while of use.


It is likely that something overheating is causing the problem, but nothing should be overheating. Cleaning won't hurt and may help but it is likely to require repair of the faulty component, perhaps a failing capacitor or amplifier.

SR4300 Centre Channel


Hi...

Try another GOOD speaker on your centre channel.
If the buzz ....buzzes off, it's a bad speaker.
If not , It's in the power amp section on the unit.

No output from left channel after crackling sound


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 !

Marantz SR 7200


It is likely that the PA stage has developed an offset voltage in the output stage. The faulty amplifier channel can be found by progressively disconnecting the collectors of the of the power transistors until the protection fault disappears. Once the faulty channel is found the the cause of the offset has to be traced to the faulty transistor or resistor. Don't forget that if you can smell smoke or burning then there are likely to be components(esp transistors) that have been damaged by the fault.
I had a Luxman unit that destroyed 5 transistors in the output stage that was due to an open .5W resistor in the driver stage.
Good luck.
