Low quality signal to harm the speakers?

[Sansiiro]

Hello!

I have noticed that some audio-fans don't connect their TV-s to their
precious sound systems.
This makes me wonder, do they/YOU(?) consider this to potentially damage their
pricey speakers, considering that the signal from TV may not be as
good as say from the CD-player?
The audio signal I get from my TV is definitely very poor.
It comes via internet to "box" then via scart to TV, then via RCA to Receiver.
I am also experiencing occasional cracklings and bass-thumps from speakers when operating
the TV, say turning it off/on.

I have no fancy speakers but would you warn against such practice?

Thank you!

I've had my TV connected to the audio gear for years, without problems.
It's a great way of bypassing the crappy TV audio internals.
In my case the TV has a Toslink out, so that is connected to my external DAC, which also has my Squeezebox Touch connected to it.

That is 95% of my audio playback on just one amplifier input - the other input I use is for my turntable setup.
I don't have problems with cracks and bangs.
If I did have such problems I would switch inputs or at least mute the amplifier output before doing anything with the TV. A remote controllable amp is a godsend in such instances.

unless the sound is heavily distorted and cranked up loud you're not going to damage the speakers.


I use HDMI from box to telly then optical cable from telly to amplifier (with built in DAC). Most channels don't have a cd quality sound feed but they all sound acceptable. Although I still miss NICAM, that gave a great sound IMO.

Thank you so much.
The distortion however sometimes happens.
A family member uses the box remote, and tunes the volume down - then another member likes the receiver remote, and tunes it way up on receiver - and she pushes it way up, if the box is at minimum volume.
Then she calls on me and says: "whats wrong with the sound?" - The sound has picked up a lot of electric noise. I think I will do smth with the box remote, I will disable it somehow.
I have been trying to use "one4all" remote, I think I will give another go.

Thank you so much again for your time!!

I think your family member is telling you that they want a more powerful home cinema system

The reason I don’t have sources like my phone or TV connected to my hi-fi isn’t because they will do any harm, it’s just that they sound awful!

[YNWaN]

Oh, the distortion you are sometimes getting is because you effectively have two volume controls, and amplifiers, in series in the system - turn the source one up to maximum and use the other to actually adjust the volume - don't use a combination of both.

Going back many decades, TVs might have had what they called a live chassis. In this case, one side of the mains (hopefully neutral) is connected to the TV chassis.

This would make connecting an external speaker or speaker / amplifier pretty dangerous. I used to do this safely using an isolating transformer.

yup, you had issues with connecting a scope too philips made one that had a tendancy to give you shocks or blow up if you were not careful... probably late 70's early 80's

If your TV box has a digital output, Virgin has optical...Sky both optical and coaxial, you can purchase a DAC from Amazon for less than 30 quid which will give a much improved sound quality.
You could, of course connect via your TV's optical out....most TV's made over the past 12 years have one.
Your box will likely have a setting buried deep in the menus to adjust sound delay if you experience lip synch issues
