Distorted Speakers from TV sound

jazzcurtis · 16-12-2015, 19:08

We have a Samsung Smart TV - UE46F6320 and are attempting to feed the audio through our Pioneer Integrated Amp model A-20K

We have used the optical input in the TV, but as the amp does not have a facility to connect to this we have bought an off board optical D/A converter. Although we are getting sound the bass is extremely distorted.

So, we have used a different amp to make sure it wasnt the Pioneer, (this Sony amp is working perfectly in another room) - the results were just the same.
Also, we have changed the phono cables from the D/A converter to the amp, same distortion.
We have checked the speaker cables, all tight and have been working perfectly ok until this problem (Tannoy 636's floor standing)

The TV does not appear to have the facility to connect phono to phono, hence the use of an off board D/A converter. There are inputs which we tried, but nothing

As both speaker are giving the bass distortion, we have discounted it being a problem with the speakers.

PLEASE....ANY IDEAS? What are we missing?

Many thanks

Look for L+R RCA audio out sockets at the rear.

What input are you plugging the phono cables into on your amp? It sounds like you might be using the PHONO (MM) terminals, which are supposed to be used for turntables only.

A possibility though that would probably produce distortion across the frequency spectrum not just the bass. It would also sound very bass heavy and treble light and the volume control would be barely off the end stop before your ears were bleeding

Plus it would be odd if the OP made the same connection error on two amps (though not impossible).

The other possibility is using a naff digital to analogue converter. Or the TV output is dodgy.

You're right on all those points, although it would be understandable to use the same connection on two different amps. The OP is using phone cables and the terminals are marked as PHONO, perhaps they are not aware that these should only be used with turntables.

I made the mistake of using the PHONO terminals once, can't exactly remember how it sounded apart from it being loud and distorted.

Could be a naff DA converter or dodgy TV output. If it's not the PHONO terminal then perhaps the OP could try the DA converter with a DVD or Blu-ray player.

Looking at the technical specs, whilst boasting of its wireless facilities it seems woefully short of other options. That's very poor design in my opinion and it would certainly put me off buying it.

Thanks to all offering suggestions. We have tried everything and I am coming to the conclusion that the TV input is dodgy even though its a new tv. We have, through a process of elimination, tried everything else. Grr

Thanks again for all your suggestions

Well the optical on the TV is an OUTPUT (not an INPUT) - and it's extremely unlikely to be faulty, more likely the converter you have is faulty - or (as has been suggested) you're using the phono input on the amplifiers, this will give loud and highly distorted bass. You need to use a line input on the amp, either Tuner, CD, or Tape should be OK.
