So…
Something I have noticed of late was that when using the Dyn8, is that in the DynEq4 part, I can only select frequencies to adjust down to 40Hz. Checking the firmware guide, I see this is correct, as per the attached image.
Regularly though, due to my venue having a government mandated SPL limit of 112dB in C-weighting, I have to try and control the lower frequencies to try and get good FOH levels while still having the best sound possible. Lately I have been having a ton of acts coming through with tracks producing some hefty sub in the 30-35Hz range. I don’t want to cut these out with an HPF, but control them.
I know that I can just set it at 40Hz, and use a wider Q, but is there any reason why A&H claim it is “Full Range frequency control”, when it isn’t? I would much rather be able to pin point the frequencies I want with a narrower Q so I am not having to cripple all the lows that I want to keep in the mix.
Surely it should be capable of manipulating down to at least 25Hz?
Anyone from A&H able to chime in? Or be able to see if it would be possible to update the DynEQ to be able to manipulate lower frequencies with a future update (preferably sooner rather than later 
)
And maybe add this suggestion that was posted some time ago which still remains something that could be implemented.
Another older Dyn8 feature request/suggestion
Thanks in advance, and if anyone has any suggestions, please chime in as well, as I am new to dynamic EQs, so am still learning their beautiful ways.
Out of curiosity, what do you need a dynamic EQ under 40Hz for?
A lot of acts come with tracks that are absolutely unmastered. Especially DJs for hip hop acts. I regularly see ±10db in the sub range. Crazy!
I do it with a slow dyn8 mbc low band and a quick dyn8 dynEQ low band in shelf mode to tame those crazy spikes.
Apart from that I would low cut almost any source from 40 below.
But for such scenarios there is a shelf available in the DynEQ.
And I use the low cut too.
As already suggested, you should be using the Dyn8 instead of the DynEQ4.
I believe the DynEQ4 is a holdover from the iLive systems while the Dyn8 was new for the DLive. Plus there really is no reason to burn one of the 16 FX slots with the DynEQ4 when you have 64 instances of Dyn8 available (unless of course you have already used all 64 Dyn8s somehow).
EDIT - corrected the number of FX slots available on the DLive (I had listed it as 12 instead of 16).

As my post said though. I am using the Dyn8.
I also said that I do not want to use the DynEQ4 part of the unit to attenuate all of the sub, just a narrow band of the problem frequencies. Oftentimes, 40Hz upwards is fine, but the artist will have a massive boost in the 30-35Hz range.
Yes, I could use the shelf option there, but I am trying to be more exact with what I am doing so I don’t cripple the rest of the input’s frequency dynamics.

That’s what I get for posting when I have a bad headache. My apologies for not comprehending your initial post.

Oh I feel you so much. Happens even on mastered tracks or from set to set. You go from disco to D&B, take +10dB @ 40Hz… punk !
I don’t like to HPF either. The subtle thumps on well balanced tracks would suffer.
Try with a Lo shelf indeed. Not sure it works. I’m adjusting the low end by EQing by hand most of the time to keep the dynamic. It’s tedious but it sounds better.

Normally the shelving would work but, when trying to keep the rest of the frequencies where they are, it seems like a fruitless task.
Like yourself, I have just taken to hovering near the regular PEQ when possible in the hopes I can pre-empt the onslaught.
