Muffled sound quality on analogue ITV1
John
Sutton Coldfield transmitter (Central region)?
I've noticed over the past week or so that the sound quality on ITV1 is
very poor compared to the rest of the analogue channels. ITV sounds
very muffled like there is far too much bass with low frequency noise
hard to hear. The rest of the channels, BBC, C4 & Five are very crisp &
clear. It seems to be only affecting ITV from the central region as I
can also pick up analogue ITV from the Granada region (although a poor
picture) but the sound quality is much better and sharp compared to ITV
Central.

Just had a listen. ITV1 seems to have quite bad top cut, on Nicam and
FM. DTT is a little better, but doesn't sound right either. As you say
it sounds muffled.
BBC1 FM sound from SC has bass cut and sounds low level compared to the
Nicam.
On the other channels, there's negligible quality or level difference
between Nicam and FM, other than the lack of stereo.

Someone's been in and fixed it now! Hurrah!

You spoke too soon as I noticed it was back to poor quality again
yesterday. Someone over at the DigitalSpy forum contacted ITV & Aquiva
who say they are looking into the problem.

Just listening now (18:30, 28th Nov, ITV1 news) it's definitely back. 5KHz
notch, funny spike at 12KHz. Oh well ... looks like I did speak to soon :)

off-air at ITV in Birmingham, why can't they hear it?
Anyway, there is a discussion about this at the following thread:
http://forum.digitalspy.co.uk/board/showthread.php?t=300206
ITV and Arquiva are monitoring this thread, so any comments posted
there would be appreciated
Cheers

They probably don't monitor anything to any detail at Birmingham now,
transmission playout of 'Central ITV' is done at YTV Leeds, Birmingham
is just a shed producing local news, and fed up a line to Leeds as a
remote source
Dave Plowman (News)
Several years ago there was a problem with the CP transmitter on NICAM -
ITV1 only. It was approx 6 dB low on one leg. Phoned The London Studios
after a couple of days and eventually got put through to master. The guy I
spoke to claimed they couldn't check off air levels...
It was, however, fixed the next morning.

Well, that explains it then. Having worked in radio with split ouputs
of commercial/jingles, it still never occured to me that TV had now
gone this way too <hangs head in shame>.
Still OK tonight since fixed a few days ago, that's not to say it won't
go again!

SuttonColdfield, Sky & Freeview. However, this time there's a bumpy
bass to it - possible phasing issue?
Mike Brown in a previous post said "definitely back. 5KHz

techie specs again, please?
I'll e-mail the duty Office at ITV, and copy in the contact at Aquiva.
Perhaps if others could do the same, please. The more they get, the
more they may action?
Hope this won't set the standard for 2006 :-(

I've just given it a listen on D-Sat, it's bloody awful, and yes there does
appear to be something odd with the L-R phase.

Central West is played out from Yorkshire TV in Leeds, and it's quite possible
that the D-Sat backhaul from there to the Astra uplink goes nowhere near
Birmingham. If it's on both digital platforms (is analogue affected too ?) the
likely suspect is a fault at Leeds.
Might be worth trying to contact someone in transmission there, good luck with
that one ! (might help to pretend to be one of Central's advertisers ;-) )

This is what it sounded like with the initial problem a couple of
months ago. However, that didn't affect Sky or Freeview, that I can
recall. After that the problem was just distinctly muffled with loss of
top-end and no extra bass-effect, as opposed to the phasing issue as it
sounds tonight

Now which one of the half dozen national advertisers shall I pretend to
be, there doesn't seem many others on at the moment ;-)
I copied my e-mail to my contact at Aquiva who had looked at the issue
previoulsy, worrying it has bounced tonight showing he no longer works
there :-(
Oh well, this will carry on well in to 2006
Happy New Year to everyone in uk.tech.broadcast :-)

Ah, I see what you mean, my typing is crap!
But yes, I did spell it as they like, it was a 'reply' to e-mail and I
always copy/paste such things if in doubt. It was the 'user' part that
bounced, not the domain.
I'll have to see what ITV says (if anything). I've not even turned on
the TV, yet!

Yup. Noticed it on the audience clapping in "Millionaire", and it was
still there through "50 more adverts you've seen before" and Paul
Zenon's "White Magic" program. Gone again when I checked today.

Email address for "the contact" ? I tried to get to the digitalspy
forum thread that was mentioned here as being "monitored" by Aquiva,
but the site was coming with empty content on that thread. It had worked
before (typical!) :)

I was dealing with a guy at Arqiva directly rather than continually via
the Duty Office at ITV, but now he's left :-(

Ah, but the sound's gone on the blink again (don't know when it went, but
from 7pm-8pm ITV1 Sunday 8th it was definitely back to muffled).
Jingleman
Oh dear, it's muffled again :-(
Reported to ITV Duty office, if others would be so kind as to do the
same?

Yes, I made a posting in this group via Google before 7pm but it
doesn't seem to have made it.
E-mail already sent to Duty Office at ITV.
Jingleman
heard it. It's so bad, I have switched to another ITV region on Sky!
I have again reported to the Duty Office at ITV, but if anyone could
analyse as Mike had previoulsy done, then report their 'techie'
findings to ITV, it would be much appreciated.
Thanks

I've just had a look [23:05, Jan 15th], and yes, it's the usual 5Khz
centred wide notch. Muffled as ever.
Last time it happened, the fault continued all the way through the night
and cleared "as if by magic" when GMTV started. Don't know if that's
significant in finding the problem. It then remained OK through most
of GMTV, and went back to muffled at the hand over "and now the news in
your local region". It then continued muffled through the rest of GMTV,
magically fixing itself mid-program later on.
It's almost like it's being introduced when a regional opt-in happens,
maybe? I don't know the exact mechanics of ITV's overnight programming
handing over to GMTV and back to local news etc. so this could be just
wild speculation!
I've put some pictures of the frequency scans at
http://www.pootle.demon.co.uk/itv/
including some of BBC1,BBC2,C4 and C5 on the same night, same equipment,
showing a "normal" trace. These are from Sutton Coldfield, Analogue
receiver, NICAM Stereo. Analogue-Mono (FM) is also affected.

Mike, thanks very much for that. If you wouldn't mind leaving the
pictures up there for a while.
I have sent it off to ITV, they have acknowledged the e-mail and
promised I will get a genuine human reply from Arquiva (however you
spell it). The copy I sent to my contact at Arquiva before, hasn't
bounced either.
It's getting now that I may be upset if they do fix, I'm quite getting
used to adverts for ITV West Country on Sky (it's one I added in for
some reason in the past).
Thanks again.

No problem. Haven't noticed it for a few days now, fingers crossed etc.
