User Question: Smaart Practice

I received a message from Jedidia, a church audio engineer in Africa, asking if I could look over his measurement data and talk about time alignment between the two sources. Here is Jedidia’s measurement setup: And here are his traces for his main and his sub: Thank you to Jedidia for allowing me to share …

Exploring Large-System Level Variance Compromises

Exploring Large-System Level Variance Compromises

Our heroes find themselves in a larger reverberant space (an armory, actually) which is, of course, the best environment for events requiring speech intelligibility. PA is twelve dual-15 boxes per side with a sub “mono block” on the ground front and center. The optimization you see here was masterminded by my friend David, whom I …

Control Booth Monitor Calibration

Control Booth Monitor Calibration

I don’t like mixing from within a booth any more than the next person, and for any serious audio work, I will fight hard for a FOH mix position. However, for “talking head” events or playback-based dance shows, sometimes a booth mix position is a reality. (In the case of the dance shows, it’s actually …

Make It A Double: Inside Approaches to Parallel Processing

Make It A Double: Inside Approaches to Parallel Processing

One of the earliest studio mixing tricks that I learned was parallel processing – running the same signal through several mixer channels and processing them independently. There are a few variants of this technique, the most common being parallel compression. For example, the first application I saw of this was when a studio engineer double-patched …

Trimming the Fat

My mixing technique is largely subtractive in nature (remove things from the mix that don’t need to be there). If I’m getting a lot of hi hat bleed through the other drum mics, I’ll pull the hat fader back. I’ll high pass, low pass, and mid-scoop mix elements that aren’t contributing necessary energy (or contributing …

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 …

Sound Design Live

Sound Design Live

I was a guest on the Sound Design Live podcast hosted by Nathan Lively. We talked about mixing monitors from FOH, workflow, and how I’ve mostly (but not completely) managed to avoid artists vomiting on my mics.  Check it out here: Fighting Microphone Feedback WITHOUT a Graphic EQ While Mixing Monitors from FOH in a …

Line Array Bench Test and Gain Setting

Line Array Bench Test and Gain Setting

RCF is a production partner on an outdoor rock show I’m running this weekend. They sent along 12 of their HDL6-A line array cabinets along with four SUB 8004-AS subwoofers. It’s a killer little rig that packs a punch, with some smart engineering – stay tuned to next month’s issue of Live Sound International for …
