What value do you use for attack/hold. I have used 5/20 ms? The I Nuke manual tells you that they are available but, it is hard to find source telling what value to use. I have used the 5/20 with the amps for around 3 years without any amp/driver damage.attack is the time it takes to react to the signal crossing the threshold, hold is how long it will keep the signal limited, and release is how long it takes to restore the signal to full.

the limiter on the "configuration" tab on the inuke is "zero attack".I have been wondering about this.......
I have the dsp software open right now and under the "configuration" tab, for the Peak Limiter there is "HOLD" and "RELEASE". The "HOLD" is default at 50.0ms, and the "RELEASE" is default at 100.0ms. I don't see a "ATTACK". Derrick when you say you have yours set to attack/hold 5/20, is that under the configuration tap? I only see attack in the DEQ tab.
I am curious what the recommended settings are for subs, and for me more specifically......Crowson's.
How popular these amps are for subs, I think it would come up more often.
for a zero attack limiter how long it is "held" and for how long it takes "to scale" back are both irrelevant concepts. the zero attack limiter is a brick wall.
I'm running the default 50/100 Keep in mind, 50ms is 1 cycle at 20hz.I have been wondering about this.......

Because I've tested it with an oscilloscope, that's how it works.why are you thinking that it scales the whole signal down. that isn't how limiters work at all. that is how dynamic limiters work.
As promised, without and with limiter.

Seems to have good control until until you push REALLY hard. It seems the limiter still functions at 0 as well, although that limit is a bit beyond the amps actual capability.

Ok, so say you have a 10v limit, and send a signal that would output 20v. It then scales the signal down 50% to conform. The hold is the minimum amount of time it will keep it limited to 50%, resetting this "counter" any time it crosses the threshold again. Say you have a 1000ms hold timer. If you send a 20ms burst that exceeds the limit, followed by lower level signals, the signal will be limited for a full 1000ms, then it will scale back up to the unlimited level over the release window.when you say "Hold is the minimum time it will keep the limit in place..."
how does that apply? with a zero attack limiter, the limit is in place constantly.
So you don't have drastic changes in output suddenly. You can control it with the settings. It's useful if you're limiting different frequency ranges as well.Why would you want to hold the limit any amount of time beyond the length of the signal that caused it? As long as the limiter can keep up with the incoming signal it seems pointless to continue limiting afterwards.
