Limiter Settings on Driverack 260

#1 Post by David Carter »

Just looking for some input on limiter settings for a Driverack 260. Obviously, the threshold will be determined using a meter connected to the amp, but there are other limiter-related settings that I'm wondering about. My DCX only has the following limiter parameters: on/off, threshold, and release. The 260 has

Limiter (on/off)
OverEasy (on/off)
Threshold (in dB)
PeakStop+ (on/off)
Auto (on/off)
Overshoot (2-6dB)
Attack (in ms)
Hold (in ms)
Release (in dB/sec)

So far, I've just turned off all the on/off stuff except the main limiter on/off. What I'm mainly wondering about is what would be reasonable values for hold and release. I assume the attack should be as low as possible (minimum is 0.1ms).

Any input would be greatly appreciated.

P.S. A quick reminder on max voltages for my drivers would help, too. I don't do this often enough to remember stuff like that. I seem to recall that it's 60V for the 3012LF's. What about the DeltaPro 8B (16-ohm) drivers in my 4xDR200?

Thanks!
Dave

You'll probably want:

Limiter: On (the obvious one)
OverEasy: Probably off; otherwise it'll begin to compress before it actually limits. The PC GUI will show this graphically where it might make a bit more sense. If it sounds bad or obvious when limiting kicks in, try creeping this up a bit to make the transition smoother.
Threshold: Determined by what comes out of the amp
PeakStop+: I see no reason not to have it on since it should make the limiter sound more pleasant, but it allows the Overshoot option.
Auto: Probably worth trying, but I'm not sure (I don't have this option on my 480)
Overshoot: The minimum possible; the manual indicates 1. Or leave PeakStop+ off. Audio is often a series of trade-offs; try both (measure amp output voltage for each), pick one. :) Saving two presets with this being the only difference will make it easy to A/B.
Attack/Hold/Release: There's still this post that could help, but there's a bit of mental conversion to make use of it with this product.

Also check out dbx's forums, there are probably similar questions with answers and everyone there has similar DSPs.
Slowly working on a pair of T30s...
