Question about Marantz SR-7400 Receiver

1 Answer

Marantz Surround SR7500 Receiver (don't know if anyone has this model)

Our receiver, on it's own, has changed over from surround sound to 2-channel stereo the last time we turned on our TV. This has happened randomly over the past few months, and I've been able to solve it by pressing random buttons. We have two stereo speakers, a subwoofer, a center channel speaker and two surround speakers, all set on A. We've never had a problem switching over to FM (goes to stereo setting automatically), but sometimes we lose the center channel and subwoofer on the trip back to TV mode. The panel is confusing, and I don't have a manual. I'm not even sure what the question should be --- how do I reprogram my receiver for surround? Why is my center channel pooping out? What happened to my subwoofer and why are my settings changing themselves?

I'm HUGELY frustrated. Ready to toss into the river. Any help is good help- thanks so much.

Hi 3303k

Strange dramas you are having there. I would suggest first, that you switch the unit off overnight(unplug at the wall) to allow for a fulll hard reset. Then fire it up in the morning again, and see if it behaves itself. I found a user manual for you online here

It is a good amp that you have, and hopefully resetting it will sort it out for you. If not, please do get back to me here and we shall look deeper..

Thanks for using FixYa, a FixYa rating would be great for looking into this for you. Happy to help further :)

Marantz NR1402 AV receiver Going to standby Mode


There could be a short in one (or more) of the speaker connections. Try disconnecting all speakers and turning on the receiver. If it still switches to standby, there may be an internal problem.

I have marantz Av surround receiver model SR301 I have tried a lot but I am having sound from only 2 speaker when I put in setero mode but when I put in surround no sound from any speakers I checked all...


First off you will need to do a little bit of trouble shooting. Is the source (dvd, Blu-ray, cable box, etc...) plugged into the receiver with the standard red and white RCA cord or by an optical (toslink-fiber optic) or digital RCA (orange color code). If you are connected with a standard RCA cord then that it your problem and you need buy digital cord that both the source device and the receiver can accept (toslink - http://www.we-supply.com/browse.cfm/optical:-audio/2,779.html or Digital RCA). If the connection is now correct then you need to make your receiver do a "test-tone" to insure that a signal can be sent to every speaker (this is an internal test that just checks the speaker connections). If the tone tone operates correctly then you know the amplifier is functioning. If both of the mentioned things are now done and still not surround output then you need to check the internal menus on your source device and make sure that it does not require you to manual change a setting in the audio menu to make it work (i.e. change from 2-ch 44KHz to 5.1 or 7.1 or Dolby Digital or AC3 or some other surround sound protocol.)

Hi There, I have a Marantz SR7005 Receiver and Bose 901 Series VI speakers with the Bose equalizer. I'm struggling to figure out the best way to connect the Bose equalizer/speakers to the SR7005. ...


It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

Yes. It is 5.1 surround. There are 2 front channels, 1 center channel, and 2 rear channels which comprise the "5" in 5.1 surround. The pre-amp output channel for a sub is the ".5".

DVD player and receiver will not play a dvd in surround sound ?


The dvd player is responsible for reading the surround sound track, and sending it to the receiver. First make sure you are playing the surround sound track on the dvd, many have a stereo track too. Next, try another dvd and see if you can play surround sound on that one. If you can't play surround on ANY dvd I would start looking at the audio connection from dvd to receiver. Are you using an optical cable? Red, white, and yellow RCA cables? Optical will transmit any sound over only one cable, RCA cables need one cable for each channel (LF, C, RF, LR, RR, sub.) If your connections are correct, is the receiver set to play a surround sound track? Is it set in 2 channel mode?

My kenwood receiver has


If you are referring to the rear speakers, it is normal. The rear speakers are not supposed to get a signal as loud as the fronts or center.

A surround sound system was originally developed for playing movies and the rear channels are for effects. In most surround modes the center channel will always be the loudest with the widest range of audio signals.

I have been repairing these type of systems since they have been on the market, so I know a lot about them.

This Kenwood you have is like most surround systems and does not have a feature that you would obviously like to have, 5 channel stereo. Only a few surround systems have this feature and they cost much more than the Kenwood systems. Denon and Marantz both make one with that feature. In 5 channel stereo you get a full signal to all the speakers. All the other surround modes you get a much lower signal to the rear speakers.

So in closing, you do not need it fixed, there is nothing wrong with it. You have a common complaint that many people have who buy a surround sound system but are not fully understanding of just what a surround systems is supposed to be capable of
. This is something that the salesman who sold it to you should have explained to you, that way you could have purchased a system that would have better suited your needs.

I would be happy to give you more help if you would like, just let me know. As I already stated, I have many years of experience with surround sounds systems, in fact I own the exact Kenwood model that you have and I like it very much. It is about the best you can get for that price.

Surround sound


The unit has only 2 channels of output thus, cannot provide surround format. Depending on your sound needs, you will have to shop around for a good 5.1 or 7.1 surround unit
