ParticipantThe limiter on the main output only works on physical outputs, SPDIF and TRS Jacks on the surface – and XLR on the MixRack.
I use my iLive for recording, and need to feed my stereo balance to:
a) Matrixes – an attenuated feed for distribution to recorders which can’t take full line level and also broadcast PPM meters which have to show -18dB as 4PPM
b) Local Monitor – via PAFL section, for control room monitors.
These two paths pick up the mix BEFORE the limiter so I can’t hear, or meter the limiting.
Of course, I never use the limiter, but there are times I’d find it handy. Is there a work around, or am I missing something?

Not sure why you need a limiter on the recording mix unless you’re running your levels high, but couldn’t you do the same there?
Of course this depends on your configuration having enough groups available.

I’m already using some groups as part of my mix. You can’t route groups to other groups can you?
You ask why I need a limiter on the recording. I work in broadcast and it’s always a live mix, straight to stereo. I’m often giving the audio to editors who don’t have time or equipment to deal with a wide dynamic range – they just need it loud enough, but not too loud.

perhaps I am misunderstanding your question but could you not just use the matrices’ limiters ???

2012/08/25 at 9:54 pm #31216ParticipantHi RayS
Yes, in theory I could use the matrix limiters, but I’m using 3 different matrixes (2 analog recorders and the PPM meters) so it’s not ideal – I’d be recording something I couldn’t easily monitor. And it still doesn’t sort out the loudspeaker monitoring via the PAFL section.
It would be so much easier if the limiter was in the right place on the mix bus!

if your mains feed the matrices then all these matrices will be post limiter/eq/comp etc,from the main L_R …..also solving your pafl problem since you would be monitoring post fader etc….??!!

2012/08/26 at 7:59 am #31218ParticipantAmazingly, NO. That’s the nub of the problem Ray. The limiter gets left out of the chain if the main output is going to a matrix. Strange but true…
Or I’m an idiot and doing something odd?

ddff_lvParticipantI believe there can be just one limiter and only at the end of signal path. Like in any speaker processor. Because it is not a part of dynamic processing, but a mechanism for protection.

2012/08/26 at 12:58 pm #31220ParticipantHmmmm – still doesn’t explain the PAFL monitor problem. It would be nice if there was an option to over-ride this. I think I’ll have to make a suggestion to A&H.
Cheers all

SteffenRParticipantIt should be possible to monitor the limiter with pressing the coresponding select.
The limiters in iLive are mainly for protection…
You can configure the compressor for needs.
The auto modes are taylored for such tasks you have.SRV-AVB
R-72, iDR-16, xDR-16, Dante2012/08/26 at 4:16 pm #31222Participantsteffenromeiss and ddff_lv both point out that the limiters are for “protection”. I’m trying to “protect” my recording from digital clipping or “overs”.
I successfully produce workable balanced recordings using the dynamics sections on input channels and groups and the main output compressor. The occasional audience member clapping extra loud will not cause a PPM meter to go above 6 (maximum) but may reach 0dB on the digital scale which gives a little red light on all digital meters. Whilst that in itself is not a major problem, it would be nice to be able to control these peaks.

2012/08/27 at 8:14 am #31225ddff_lvParticipantIn order to protect mix from clipping I suggest to use compressor with appropriate settings. You should be able to replicate limiter with all the controls you have.

ParticipantI thought it worked as I use compression and limiting on our record buss although I don’t use LR to record but I have a separate Post fade stereo Aux with all the faders set to 0dB which I then route to OB, the CDR and Parent’s Room via matrices as appropriate.
I will check out the LR limiter just to satisfy my curiosity next time I am in front of it…
