RCF HDL6-A Outdoors

RCF HDL6-A Outdoors

This past weekend, I mixed an outdoor concert with RCF as the PA sponsor. My colleague has been planning on investing in a new compact-format array system for a while, and this event proved the perfect occasion to do a test drive. A trim height of 17.5 feet on an SL100 and a coverage area …

Understanding LF Headroom in Arrays

Understanding LF Headroom in Arrays

Modern line array elements have very narrow vertical dispersion at high frequencies, which allows us to manipulate inter-element splay angles to manage overlap and therefore power addition. However, at LF, dispersion is very wide (approaching omnidirectional) and the elements overlap regardless of splay angle. Thus, all boxes in an array contribute to LF headroom over …

My Measurement Rig

I’m asked on a relatively regular basis what gear I’m using in the field, so I figured I’d post it here. Audio Interfaces Roland OCTA-CAPTURE (8-channel interface. Since the preamps are digitally controlled, Smaart can track when you’ve adjusted a preamp level, which is helpful) Behringer UMC404HD (4-channel interface, and bus powered unlike the Roland so …

Why Your RTA App Isn’t Showing What You Think It Is

Why Your RTA App Isn’t Showing What You Think It Is

I was recently reading a forum discussion about whether an external mic was necessary when using a mobile app for RTA / spectrum analysis.  It had occurred to me that the physical dimensions of the device might cause some significant spectral variance as the device’s orientation changed relative to the source. In other words, the …

How to Look like a Phase Alignment Wizard

How to Look like a Phase Alignment Wizard

I’m going to show you how to quickly estimate alignment delay values in your head, which is a hell of a party trick if you’re at… a system optimization party? This might seem mathy, but it’s not. If you passed middle school math, you can handle this. We’re going to look at the delay needed …

Filters, Phase, and the Double Patched Kick

Filters, Phase, and the Double Patched Kick

This post comes on the heels of this article by my friend Jim Yakabuski, and my recent article about double-patched channels, so if you’re not up to speed on those, check them out and then come back. I’ll be here.   Back? Okay great. So the discussion now is that we want to split a …
