I would suspect that the radio is not installed correctly. There should be 12V present on one wire for retaining memory. There is a capacitor inside the radio that will retain memory for a short time (less than 5 minutes), but you should not have to reset the system after each start. If the wiring is correct, then the internal memory system may be defective and require replacement.

My Yamaha RX-A830 won't play the sub. I've reset the speakers with the mic multiple times but it's still not working. I confirmed that the sub works on another receiver.


There is a difference between SUB and LFE. In 5.1 mode, the LFE is the ".1" channel. It will output bass only when audio information signal is addressed to this channel. In stereo mode, depending of the receiver setting, it can output normal bass when front speakers cannot handle low frequency. In setup menu, you'll probably have to set your Front speakers as "Small" to make the sub channel taking the relay in low frequencies. There also can be many other reasons for your problem but this might be the solution. Good luck!

I can't determine the best listenmodes for DVD and particularly VCD. I have a 5.1 fazor Dali speaker system. I listen to music in 'all channel stereo'. My preference for movies would be thx. For vcd this...


The 'best' audio result will always be subjective, but when it comes to digital multichannel content, the engineers probably had it right, so I'd go with Dolby Digital, THX for movies; and experiemnt with all the others for muical content becaasse any given audio recording can yield surprising new details when you turn DSP loose on it.

Is there any way i can use all channels regardless of source? i would like to understand what i need have as an input source inorder to use all 5.1 or at least 4 speakers


The answer is yes - and no. By definition, audio sources are encoded or recorded in a specific manner. If I record a stereo signal, there really are no rear channels or center or bass specific channels. To be most faithful to the original, you play back stereo in stereo and 5:1 in 5:1 and so on. There ARE several units designed to "synthesize" additional channels from sources that do not contain all the info specifically. Some multi-channel receivers/amps incorporate such circuits and you can "derive" rear channels from stereo inputs and so forth. If not, you may need an additional box (device) to turn 2 into 4 or 5, 3 from 2 and so on. Your choice but that's how it works.

Just want to know watts per channel in traditional stereo mode.


Im geusing this means not all channels driven, but in reality it will be the same as the left and right speaker output regardless of if its in multichannel mode, whenswicting between all it will do is bypass the ADC/DSP/DAC circuitry and use a relay to directmode, it will not turn off the other amps, only the input to them, so you have the same amount of power avaibly for the right a left channel which will be 110 watts at 0.08 THD at 8 ohms, which is **** anyway, if you want it for pure stereo and nothing else, buy a dedicated stereo amp.

One channel not working (no output) when useing various modes


Hello

I had a similar problem, now to be honest there is quite a couple of things that could be faulty. I dont know which cable you are using between the source and the amp, but i am using RCA to mini jack.

I had the same problem that my tuner on amp played through all channels dvd as well, but as soon as i hook up the amp to my computer only some of the chanels played.

I found out that there is actually mono and stereo versions of of that cable thus, if you use a external source and channel it trough the amp with a mono cable, only some channels will be playing.
If you use a stereo cable both channels will work.

The other problem could just be a simple setting on the amp itself.
Usually you can set the number of channels you want the amp to be set on. It is very simple, locate this function an try every setting untill you hear that all channels are working.

It could also be an "ic" on the heatsink of the amp which overheated, if you open up the amp you will be able to see it instantly. This will explain the slight sound you manage to hear.

My advice is to try the first and second sollution and as a last resort send it to a repair shop or if you still have warrenty send it back. I doubt that it is a hardware problem on the amp itself.

Please rate this.

Best regards

It could be a bad balance control potentiometer or just broken/cold soldering joints due to the age. Bring it in a repair shop. Thanks. ebcelectronics

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


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 :)
