Sound outputs on flat screen tv's

place within the digital domain - hence it also affects the sound on
this output.

Then get yourself a decent set. Tone controls operating on a line output
is a nonsense.

As a rule this is true, but the Armstrong 626 Receiver I used to have
allowed the bass, treble and filters to operate on the line output.

Thank you for all the replies. I'm still a bit confused, but will endeavour
to pressure the seller, into to convincing me that it will work as I want
before I buy.


Have you considered asking the RNID? I would expect them to be
particularly interested in your particular problem and may have carried
out their own research into the suitability of different models.

Once again Thank you

I think you have the right idea. What's more, if you can prove that the
retailer has claimed certain things for the product (take a witness in other
words) and it turns out that it doesn't, you are entitled to a full refund.

I was hoping that others would give you a lot more advice, because this
isn't my subject. Indeed there was a bit of good advice, but certain people
had to start their barneying and spoil it.

The mark of a true gentleman is that he behaves like a gentleman even when
unobserved, or in the case of usenet when he is anonymous. Some of us do,
but many are like polecats.

That's unusual. It would be useful though, when feeding a power amp with no
controls.It would remove the need for the 'pre-amp' if the power amp was
only used with the TV set. It's a bit silly really having to use a seperate
remote handset for the audio.

I hope Jim Lesurf has got an excuse for that. ;-)

However on an old Hi-Fi amp where you might be copying disc to cassette
there is some justification for it. But not on a TV to feed an external
amp with its own tone controls.

Two things. If using decent speakers there's no need for tone controls.
You need separate remotes for TV and STB, DVD, etc so why not the amp? And
presumably you'll use it for other things like radio and CD?

Since I was involved with the 600 range I can add two points.

Firstly, the ability to use the tone controls and filters to alter the
output to tape was included as it was a feature users had asked for in the
'questionnaire' cards we sent out as part of the guarantee registration.
IIRC the feature was also in the earlier 400 and 500 ranges. In some ways i
guess it may stem from early days when the owner of a hifi might have to
arrange for his own 'PABO' (Playback Amp and Bias Oscillator) etc when
using a tape deck that came sans electronics. But that was in the distant
past even by my standards, so I don't know. :-)

Secondly, on replaying tape the user can choose to either use the 'tape'
input via the source selector, or press a 'monitor' tab. The selector
choice goes via the tone controls and filers. The 'monitor' bypasses them,
giving the user a choice.

Curiously, the above made the 600 popular with at least one radio 'DJ' of
the time who used to pre-record his program to tape to send to the BBC.

Modern fancy hifi kit often tends to bypass the decision by not actually
having any tone controls or filters. And perhaps also perhaps having no
gain stages at all prior to the volume/balance control. During the 80s it
became tendy amongst the 'golden eared' to say that tone controls always
degraded the sound, so should be omitted from the circuitry.

FWIW I still have a couple of 626s that work fine despite their age. Still
to the original spec when I last checked them.

Slainte,

Jim

If it's this one:-

It does have a headphone socket - so jamie is wrong yet again.

But if you know which model you want Google it and look at the spec for
'headphone'. Not speaker as you said earlier.

Hey meathead,
Did you read the bit where I said "They've omitted the 3.5 headphone jack on
MOST TV models"?
Are you not familiar with the meaning of the word "most"?
