Nihilism FTW. Bringing in guests as often as possible so you can pinch a lunch voucher seems to be the standard method to make what you described more bearable.

Teams are on super-cardioid desk mics, desk is acoustically treated and the 3:1 rule is (almost) always adhered to. Presenter has a lav where the bas tilt is deployed to add to the gravitas. Defo fig 8s on audience as well. I think that format is about 50 years old?

Haven't been around these parts for a while, but popped in and found this. I've been the sound supervisor for this show since 2001, and your comments are most kind. Here's a bit more info if anyone's interested.

The desk mics are currently Sennheiser 8040 cardioids; I've tried 8050 hypercardioids and although the extra suck was welcome it caused the dialogue while the teams chat to each other to go more off-mic. The desks aren't great acoustically, being mostly wooden tops with glass panels for TV flatscreens, but it works ok with the proximity of the mics.

Roger Tilling performs the VOs live in the studio; he sits next to the audience and has a Sennheiser 416.

Jeremy has a Sony ECM77 omni lav mic, mainly because a desk mic would pick up noise from his question cards, as well as being blocked sometimes by them. It's always put on the same position high on his tie, on the right side away from the teams, and then as you spotted it has a specific EQ curve to make it work. His desk DOES have some acoustic treatment on the raised edges to stop the "honk" from the height and distance of his tie mic.

All mics have 5:1 soft-knee compression tickling for normal speech, and go into a group with 10:1 to even out and give a nice average speech level. No auto-mixer is used; the show is hard-mixed by hand with lots of fader movements. There's also a CEDAR DNS 1500 stereo noise reduction unit across the group because there's quite a high noise floor from the studio lights.

Audience is about 70 people, and are covered with 4 Audio Technica cardioids dropped from the roof to about 8 feet above their heads. Lots of gain for the occasional laughs, 10:1 pre comp and then 50:1 on the main audience group. Whole mix then goes through a final TC6000 brickwall at - 3dbFS for R128 compliance, and goes off to the edit.

The whole mix is kept at around - 23 LUFS, and I deliberately keep the loudness range fairly small so it hopefully translates ok on domestic tellies.

(Just to contrast with the comments on large mix environments, I mix this and all our other shows with a pair of Harbeth Monitor 20 bookshelf speakers which sit just behind the meter bridge.)

Indeed - a real insight into the nitty gritty of quality audio recording to suit a particular scenario.

Thanks Jake!

Thanks for the info Jake, very interesting.

What equipment is used to provide FOH sound for the audience?

We've got 3 Nexo PS10 speakers slung on trussing above the front corners and centre. They're nicely directional, and don't have an extended bottom end response, which is just what you need for TV speech. No subs; there's only a small amount of music in each show and it's never at concert volumes. They're at least 25 years old and currently showing no signs of breaking down. The audience mics then sit in between them, 2 front and 2 rear, and their group fader is worked very heavily to control PA colouration.

The teams each have a K-Array Anakonda speaker hidden in their desks, and Jeremy has a small active Fostex speaker by his chair, although he hears the teams mostly through his earpiece.

Teams and presenter hear a "mix-minus" of speech with everyone but themselves in it, which are all sent from post-fader channel auxes. This and the hard mixing style keep any spill under control.

Thanks for the detail Jake. :thumbup:

Coincidentally, we are looking at replacing our current PA system in our main studio with Nexo PS10s also. The current system was installed sometime in the late 80s/early 90s and is comprised of 8 EV SX300s powered by Crown Macrotech amps. Each speaker is hanging from the studio grid on its own lighting ‘scope.
It seems crazy to me to be driving these ancient budget speakers from a beautiful new Digico SD5 but it’s what we’ve got for the moment. The audience for most shows in that studio is 200 people but the configuration changes from show to show so we need to be able to reposition speakers to suit the production.

Do you do the FOH mix for from the broadcast desk or is there a dedicated FOH console?

I have not entered the debate so far but last night I watched the first Dirty Harry film. I have a modest, mainly home built 5.1 system (but no rear speakers at the mo) and I was struck by the high quality of the music and the crisp dialogue.

So yes, much modern sound production is poor to dreadful IMHO and I agree that a large part of that is due to the lack of consideration of the rubbish speakers in FSTVs but even in my quite decent system 'FX' music often drowns out speech and is often totally unrelated to the picture and unecessary.

The picture quality was also excellent and even in the night scenes they lit the action where it was needed so you could follow it.

Contrast that with the recent production of War of the Worlds. I know it was SUPPOSED to be soul destroying but the lack of light became such a strain I gave up in the end. I will confess I found the plot line hard to follow. Maybe I should read the book?

It's all fed from a post-fader aux on the broadcast desk. The actual mix to FOH is more or less the broadcast mix minus the audience mics, with odd tweaks depending on the studio geography; for example the VO is slightly lower because he's virtually in the audience. I set it up all by ear with feedback from the floor crew, then it's saved and recalled each time we come back.

This is another common problem. The gamma curve of Plasma TVs screens is quite different to that of LCD TVs. Plasma screens can cope very well with low-light images -- you can still see detail in the dark bits. But LCD screens tend to just go black and all detail is lost.

Needless to say, with the increased sensitivity of modern cameras, it is genuinely possible to light a scene with single candles these days and, as most productions are shot, edited and viewed using expensive plasma screens (moving to OLEDs now), or projected in low-light viewing theatres, it all looks great and 'moody'. Meanwhile, viewers at home with the £50 LCD sets from Tescos (which they're viewing from well off-axis) can't see half of what's going on!
