Members kayak Posted August 30, 2004 Members Share Posted August 30, 2004 Anyone here using the iEQ31 AFS system? I want to know if the filters in live mode tend to try to grab sustaining music notes, whether it be from a guitar, bass, keyboard, or vocal?

CMS Author Craig Vecchione Posted August 30, 2004 CMS Author Share Posted August 30, 2004 I'm pretty sure this is the same system used in the Driverack PA. It works by sensing a frequency that's starting to feed back, basically whatever exceeds a certain dynamic limit, not by how long that note is held. It hasn't affected sustained notes in my experience. My only complaint is the lag between a note feeding back and it being clamped, but this is unavoidable. For that reason I set mostly fixed filters and keep my peak volume well below the safe range, using only 4 live filters as 'just in cases'.

Members Black Frog Posted August 30, 2004 Members Share Posted August 30, 2004 Craig is right- same circuits as in their Driverack. I just got my IEQ31 two days ago and haven't had a chance to use it live yet. I do wish it had a highpass filter on it though, other than their 40Hz lowcut switch..... Craig, have you used the Type III noise reduction feature on yours? comments on it? Link to comment Share on other sites More sharing options...
Members B. Adams Posted August 30, 2004 Members Share Posted August 30, 2004 I got my iEQ about 6 months ago, and I still don't really know how to use the damn thing. Somebody on the LAB told me once, but I can't remember exactly what he said. One of these days I should really set up that feedback thing. Maybe this weekend I guess.

Hmmm, I'm guessing no, I haven't. Not because I don't want to, but because I didn't know it was on there. My rig is pretty quiet, so I'm not sure it would be a good test case, but anyway, where's it located, menu-wise? I'll check it out tonite...

Members Black Frog Posted August 30, 2004 Members Share Posted August 30, 2004 but anyway, where's it located, menu-wise? I mistated, it should be "Type V noise reduction" instead of III. No menu- it's on the front panel. Left side, bottom-left button for each channel. Labeled "TYPE V NR". I believe it also has an indicator light for engagement. I don't have my unit in front of me to be sure.... If you have yours hooked up to a rig- I'd be curious to do some vocal things with and without the NR engaged and see if you hear any noise floor differences. I'll get to do it within the next couple of weeks as we are setting up the new rack and rig, but I'll have to wait to play. Link to comment Share on other sites More sharing options...

Members Black Frog Posted August 30, 2004 Members Share Posted August 30, 2004 ohhhh...... my mistake. I thought when you were referring to the AFS circuitry that you had an IEQ31. Link to comment Share on other sites More sharing options...
Members B. Adams Posted August 30, 2004 Members Share Posted August 30, 2004 I pressed that button once, and I didn't notice any difference. I have a pretty quiet system though. I guess I just don't have much of a need for noise reduction. Link to comment Share on other sites More sharing options...
