      Anyone here done this for a corporate or broadcast environment? This is for a community radio station where there isn’t an extra producer to balance the levels of the guests, and the main presenter may well be sat away from the main console.

      There are 3 mics, some odd condensor things like PC mics but slightly higher end. They have them big circular windshields before them, the station manager said that the guests sometimes forget to keep correct distance and the presence of these stops some of the popping. He did mention wanting to have tech ops like the old days but if the shows are TX’ing at office hours that means guys like me can’t always attend to do this. I didn’t get a chance yet to see how exactly they were connected to the main console (possibly all 3 via some local amp into a single line level channel!) but of course the different presenters have different voice volumes and sometimes if they are all talking at once or laughing the output (from a recorded audio stream) even distorts!

      Also there are clunks and thumps from somewhere, either a mic is slowly coming adrift from its mountings (they are supposed to be isolated from people setting down scripts and other stuff on the talks studio table and poke through a hole in it) or someone is knocking into a windshield…

      I think this has gone unnoticed because its hit the limiter on the TX chain but the recorded stream (for “listen again” and also ofcom logs) is raw (well I couldn’t see or hear any soundprocessing on it, which otherwise is a good thing as the station still has dynamic range). But the off air monitoring in the reception/traffic office is via a cheap ghetto blaster and I bet the cans have the politically correct limiter to protect the users’ ears so no one is hearing it..

      is there any affordable kit (this station doesn’t have much of a budget) that could be used to give better control over these levels? I was thinking one of them cheap soundcraft 4 way mixers, behringher 4-way compressor and peak limiter like this, and filter off some of the low frequencies? its a bit of a “dirty way” of doing it but surely this could be set for most levels of sound and shapes/sizes of people and left as it is?

        The snag with the linked kit is that it’s general audio. What I reckon would be better would be a real time vocal auto-level control… hang on a minute, I’ll go for a Google…

        Quite a few of them are software plug-ins for existing packages, which (if the station already is using a package) would not mean extra hardware.

        The snag with karaoke equipment is that it suppresses vocals out of tracks – what you want is the reverse effect!

        Hope this helps mate, I’m in a bit of a rush today.

          Have you considered getting an automixer? These are typically used in place of an operator and carry out the basic functions of mixing automatically, such as gating mics that are not in use, levelling, EQ, and they often have a limiter on the output.

          Perhaps there is a similar Behringer product if the Shure is too expensive? I’m AV teching in a conference atm (it’s well fucking dull) so don’t have much time to search the internet.

          Btw I own one of those compressors you linked to, I don’t like it very much but for rough-and-ready speech compression it’s probably ok.

            cheers both of you – I think Auntie use the Shure kit and other similar devices but its not cheap…

            I visited the studio again yesterday and had a better look – turns out that there is a local mixer there, but it was placed in a odd corner where no one could easily get to it rather than in the second studio, which is not always in use! the tech op would not be able to see the guests (not such a disaster as he/she only needs to hear them like the listeners would) – but talkback hasn’t been wired on any of the consoles nor cue lights …

            this whole lot must be shifted anyway to a new studio location, so that issue can be dealt with – I spoke to the station manager and he is in favour of having all speech based shows with a tech op anyway, and although many of the presenters cannot do this due to work pressures, there is a University and FE College within walking distance of the studios both of which teach media production..
