Anyone got any opinions about the sound quality of built in speakers on
a 26" lcd tv? 2 x 10 watts seems to be the norm. Is it significantly
worse than a CRT? If so, is there any way to run external speakers that
can be controlled with the tv remote? TIA

Our main TV source is the freeview box/PVR, which sends the sound to the
main stereo. Volume can be controlled either via the freeview box or the
main amp. Beats any internal TV speakers by miles. I think I can do the same
with the DVD player, though don't try that nearly so often.

I realise that doesn't answer your question exactly, but thought it may give
you different ideas :-)

Yes, thanks. Interesting that your freeview remote effectively controls
the tv volume. Does this mean that an amplified speaker can be
controlled by the tv remote? With two volume controls how would you know
which levels to set? Trial and error?

Sound from modern flat screen TV's is dire, in part due to them having
no side depth and the box being not much bigger than the screen size.

If the set has outputs for external speakers, then buy some. Failing
that, feed the L+R low level outputs to a stereo system. Even better
would be even a cheap Home Cinema system. Mine includes a DVD + radio.
I do though find on live studio feeds that I can hear noises from
outside the studios, like passing cars with their stereos on full
blast.

You can buy programable remotes and mix the features of two systems so
it controls TV and stereo (for volume only) within the same control
set.

yes, its inevitable. But be grateful for progress.... Had a blast from
a 1950s tv a few years back, and christ was it bad. Very little cone
travel, stiff paper suspension and probably valve bias way off.

If modern TVs used the rear plastic case cover as a flat panel speaker
for lowish frequencies they'd do better.


You could connect some vaguely decent speakers to the internal speaker
connections. Any ok quality small bookshelf stereo speakers of
freecycle should do, eg celestion etc. The other option is to bypass
the tv sound amp/speakers entirely and connect something mildly decent
to your decoder box.

IMHO no TV ever made has speakers which do justice to the transmitted
sound. External ones are a better bet. Decent ones will also have rather
longer a life than the TV. Better sets should have adequate power amps to
drive reasonably efficient ones.

Yes indeed - and this appears to be a problem to the OP, because the set's
remote doesn't control the volume (or mute) the line output. Therefore, if
you feed the line out into (say) a hi-fi system, you need a separate means
of controlling the volume.

I guess this is something which most of us learn to live with. When
watching - for example - the last night of the proms, I mute the TV sound
and control the volume with my hi-fi remote - but this does, of course,
require *two* remotes.

Oh I donno my 1985 vintage Panasonic Prism A1 had pretty good sound.
Being at 26" 4:3 there is loads of room in the box for proper
enclosed speaker cabinets. IIRC there is a 1" tweeter and 4 or 5"
main driver. Fair bit of umph (for a telly) available as well 25W
RMS? This set was bought on the basis of having good sound mind.

Pity it's stopped wanting to play, I suspect a diode in the PSU. At
least there is a large diode with a brown coat and scorched PCB...

I've not listened in anger to modern sets other than the cheap stuff
you find in hotels and they really are dire. 3" speaker mounted
directly on the flexible and rattley external cabinet and no rear
enclosure.

With TVs there is typically a headphone socket that mutes the interna;

625 certainly did that, not sure about 405 though, Might well have been AM.

If you mean using both internal and external speakers at the same time, and
adjusting only the volume of the internal ones, that would probably work -
but the mute button would only mute the internal speakers, and the external
ones would carry on.

No! The audio out is a low level signal from a high (several K-ohm)
impedance source, and needs to go into an amplifier. To drive passive
speakers you need to be able to deliver much higher currents from a very low
(a few ohms) impedance source.

They could but are likely poor value compared to passive types.

10 watts will drive most speakers to a more than adequate level for
ordinary TV listening. And pretty well any half decent speakers at say
80-100 quid will knock spots off the internal ones.

Just tried a pair of powered PC speakers on the TV. Output is 2 'jacks',

just a small jack for a PC, so I couldn't connect that.
Shoved the small jack in to the TV's headphone outlet, turned on both (with
the speaker volume down to zero, wound up the volume and it worked.
Bit weak at first, so set speakers to max. bass and min. treble and the

Took the speakers off as it wasn't worth the clutter for the result.

Next: see if I can wire the TV to the amp. and then to the KEFs :-)

Well yes, I knew that it would be far less than for the speakers but more
than that for powered speakers, which is why I started with the volume on
0. Didn't want to wreck the TV or my ears!

impression is the OP has only a line output - which will deliver
only milliwatts, and require an external amp of some sort.
I haven't got the tv yet but nothing in the spec tells me what sort of
line output it has.

Remind me what set it is, and I'll see if I can find any hidden clues in the
spec.

The spec itself isn't very explicit, but says that audio out is via two RCA
(phono) plugs - which usually means an un-amplified line output.

In the URL which you quote, there is an option to download an operating
manual. The spec on P57 of that explicitly says 0.5v RMS (High impedance).
This means - as I suspected - that this output will *not* drive passive
speakers without an intermediate amplifier.

FWIW, the same audio output signals are also carried on the appropriate pins
of the SCART plugs - should you want the connect them to anything which has
SCART at the other end.

No speaker outlets on the spec. But then it's described as a 'bedroom' set.

They used AM sound. The sound IF was at 30odd megs and was wide
bandwidth, and did not restrict the audio bandwdth. AM radios have an IF
of about 0.45 MHz, and just that difference will reduce bandwidth on MF
radio (as compared to 405 TV sound by a factor of about 75.

In practice most sets did. When BBC 2 started with FM sound it added an
extra octave or so at the top end via the average receiver.

Thanks, Roger. Much appreciated.
Looks like I'm going to be dragged kicking and screaming into the
surround sound world!
How practical would it be to get a cheap ASDA set, ditch the 5 small
speakers, and use the amp/sub woofer/remote control with a couple of 16
watt mini hi-fi speakers I have lying around? They do a 40 watt and a 70
watt system and I'm guessing either would be enough. As I'll only be
sitting 2 metres from the tv, I really don't need home theatre stuff.

My living room is about the size of a bedroom :-)

Just tried a pair of powered PC speakers on the TV. Output is 2 'jacks',

just a small jack for a PC, so I couldn't connect that.

So unless I'm being really fick a phono-phono lead from the poundshop
would connect TV to speakers?

Owain

Yes, but it was only a test to see if there was any real change - and my
nearest shop with such leads is a 2h trip.
It wasn't worth any trouble, as the speakers aren't good ones. I'd like a
2.0 set-up with reasonable speakers (hence amp. and KEF); don't really want
2.1 as I dislike false bass and there's not enough good stuff on TV to
warrant much trouble or expense (now Radio 3...).
