Best Seat In The House

On-stage may not be where you’d expect to hear the best sound in the house, but that’s the aim of the foldback engineer.

Face it: being a front-of-house audio operator is the glamour job. Once the trucks are empty you roll up with a shiny briefcase filled with a few irritating CDs and some headphones, survey your perfect domain – a mixing position at the best seats in the house – and your office is all ready to go. You get the adoring fans, the near-naked girls hurling themselves at your feet (or just hurling on your feet), and at the end of the night all the accolades for a great sounding show. You’re a mere step in line behind the performers themselves in the queue for fame, fortune and recognition. Plus you have the luxury of telling the band afterwards, “yeah, it sounded brilliant – awesome” and how the hell would they know any different? They couldn’t hear it.

The guy (or gal, of course) who’s really under pressure, however – the one who has to perform perfectly for every minute of the concert – is the humble foldback engineer. Always the bridesmaid and never the bride, the foldback operator gets the lead vocalist dashing across the stage and literally screaming in his or her face that he or she can’t hear “a f**king thing in the monitors.” You’re supposed to interpret fleeting, minimal finger movements as perfectly clear instructions and endure a hundred different ways a singer manages to point the microphone directly into the front wedges – and they still don’t get it when you again later ask that they don’t do that.

BACK INTO THE FOLD

Running foldback is a tough job, sometimes appreciated but rarely acknowledged. It’s also the job that can bring you the most grief, if you’re not completely on the ball. Preparation is the key, whether you’re working with a band – and a rig – for the first time, or the 300th show on a worldwide tour. Some things are perhaps bleedin’ obvious, which means they’re the first to be forgotten and you’ll get into trouble. Others are deeply secret and you mustn’t divulge them to anyone – chew and swallow this magazine after you’re read these.

Okay, before we dive in I must clarify that we’re talking about a large and conventional foldback setup here without any in-ear systems – they’re a different beast and another story altogether (which we covered back in Issue 70). This issue we’re talking specifically about lots of wedges on lots of sends with drum-fill and side-fill included. We’ll also assume everything is up and running correctly…

So now, where do you start? What are you even trying to do?

Ideally foldback is about creating a cocoon of sound on stage that’s the perfect environment for the band. Get this straight – the foldback mix is never secondary to the FOH and never compromised for the sake of FOH either. Without a doubt it’s more important than FOH. If the band is happy in their workplace it will translate into a great show and the FOH engineer gets it easy… well, relatively at least.

Cut a Rug: Foldback is about creating a cocoon of sound on stage that’s the perfect environment for the band.

FOLBACK ENGINEERING

First and foremost, the foldback engineer has to project confidence and professionalism. This means becoming one with the signal paths on your mixing console, outboard processors, the output buses and where they go with respect to the wedges on stage. Label everything clearly. It doesn’t matter if you’ve done this a million times or not – always make Send 1 the centre pair, for example. It doesn’t especially matter what order you choose to put things in, just so long as these elements become second nature to you. In the heat of the moment you’ll need to instantly grab the correct fader or knob and believe me, when the chips are down you don’t want to suffer even an instant of hesitation in front of your employers. Musicians get nervous easily, so the idea is to build up an intimate knowledge of the console until you can literally operate it in the dark – which you’ll probably have to do at some point.

Next, establishing the real-world limits for each section of foldback is very important – and I mean standing on stage yourself with a microphone and finding the maximum physical volume that should ever be fed through those wedges, then identifying where that level is on your mixing desk. Remember, on a good system with plenty of headroom this isn’t necessarily going into the red. In fact, forget meters for a moment. With a flat EQ, determine with your own ears what you’d consider bloody loud and mark it on the desk even though (hopefully) you’ll never be pushing things that far.

WORKING ON STAGE

The problem is that foldback engineers generally don’t have the benefit of listening to their mix as they work – which is kind of crazy, but a fact of the foldback engineer’s life. It’s like a pilot flying on instruments on a pitch-black night. What we’re trying to do here is set safety benchmarks. Sure, the goal posts can shift a little with compressor tweaking and different performers, but not much. The concept is that, if things go pear-shaped and you’re asked to push the on-stage sound harder and harder to a level where you figure things are getting ridiculous – yet the performer is still insisting there’s not enough volume – you have a finite point where you know it’s got to be near-deafening and therefore the problem, if it exists at all, must lie elsewhere. Hey, these things happen. Speakers and cables fail without warning sometimes and the vocalist for example might be right – there isn’t any sound coming out. However, what usually occurs is that the band gets progressively louder and the singer more deafened. In this situation you must not let yourself be pressured into running signal levels beyond what you’ve determined to be maxing out – bloody loud, remember? It’s a recipe for feedback disaster.

Back-tracking a little and repeating myself, never hesitate to jump up on stage during the setup and listen to what the performers are hearing. In emergencies, even do it during the gig. Don’t get entrenched behind your mixing desk thinking you have all the answers and information at your fingertips. Headphones are useful, and having your own powered wedge running from the phones output is even better, but nothing beats hearing the foldback mix from the band’s perspective. Get out there and listen!

SINS OF THE PAST

The latest foldback monitors are pretty well designed pieces of gear and shouldn’t need much EQ’ing (stage monitors produced in the 1980s and ’90s were nightmarish to work with and the perception that foldback needs extensive EQ’ing still lingers). Some of the modern, dual-purpose, self-powered speakers like JBL Eons can maybe benefit from a little tweaking to help them adapt to the foldback role, but not in a bad way. Positioning issues can cause feedback problems such as a wedge that has to be placed side-on to a keyboard vocalist. Low ceilings over a stage can be difficult, too.

Whatever is causing the hassle, if you still find that EQ’ing is necessary, don’t ever, ever ‘squeak test’ the system. This is the old method of putting a live microphone on stage and pushing up the gain until things start feeding back, which supposedly reveals any troublesome frequencies. There’s about, oh, a hundred reasons not to do this, but I’ll give you three. First, you can damage your equipment and your hearing. With the latter I’m not being alarmist and suggesting you’ll be rendered stone deaf, but one decent feedback squeal can kill off your top-end hearing for half an hour or so and any adjustments you make during that time will be worthless. Secondly, it’s a pointless exercise anyway. An open microphone on an otherwise quiet stage running at high gain levels doesn’t remotely emulate the true performance conditions, so why bother? Thirdly, and most importantly, it’s really bloody annoying. Really annoying. Nothing will make you more unpopular with everyone faster than a sudden 8kHz screech from the wedges. Do it repeatedly and you’ll get lynched. It’s unnecessary and aggravating. If you have a tricky problem and it’s unavoidable that feedback will occur while you’re working on it, warn everybody. Better still, clear the stage area if you can. Mind you, creating extreme EQ settings to kill off feedback should be your last resort anyway, and a wedge that’s made to sound like crap to avoid feedback is next to useless. If you’re in this situation, try a different monitor or another microphone if you can. Also, move the wedge around and get it away from the offending microphone. Try everything else, before mashing the sound to a pulp with EQ.

Know Your Console: You’ll need to be able to instantly grab the correct fader or pot without hesitation.

THREE GOOD TRAITS

Technical skills are plainly vital and good equipment makes a huge difference, but the most invaluable assets a foldback operator can have are patience, tolerance and a sense of humour. In other words, ‘people skills’. We all know a stage can be rife with egos; the real trick is not to trample on them. Treat every member of the band is if they’re the most important. Give them equal time and equal consideration. Create an atmosphere of co-operation and often problem areas like too-loud guitars will be seen by the band for what they are, rather than a guitarist stubbornly insisting on a particular ‘sound’ because he or she feels like they’re playing second fiddle to someone else. A seasoned foldback engineer is part mixer, part psychiatrist and part expert in conflict resolution. Never hesitate to politely communicate your problems with the band. If a singer has a soft voice, tell them. If a guitarist is too loud, tell them. I can guarantee that 99% of the time they’ll be well aware of these things, but often nobody’s had the courage to say them out loud. If you’re being honest and professional no-one can complain.

Finally, check out the real logistics about the band early and maybe save yourself a lot of hassle. Countless times I’ve been asked for a vocal microphone for every member only to be told later that someone only sings once in a single song and it’s not so important – they don’t really want it. Also make sure that vocalists won’t be bringing their own microphone and, if they are, get hold of it for your setup time. Another tip is that sometimes you’ll need to mic up something twice: separately for FOH and foldback. Grand pianos are a good example of this. The kind of delicate, condenser microphones that can produce excellent FOH tones are occasionally too sensitive for feeding a foldback wedge. Dedicating a separate mic – perhaps something that’s much more tolerant, like an SM57 – specifically to the task of driving the foldback wedges can be the best and least time consuming solution. A word of warning if you use this technique: make sure you explain to the pianist that the foldback they’ll be hearing isn’t representative of the FOH quality. You might have to repeat this four or five times if they’re a particularly obnoxious jazz pianist (okay, I must let that one go…).

Good foldback is all about building a good sound on stage, not some technically complex yet strangled, over-EQ’d and compromised mix to accommodate a combination of problems. Take your time, work on it and try and create an immersive on-stage sound that’s the best seat in the house. The band will love you for it…

PHANTOM MENACE

But hang on, what was the deep secret I was going to divulge?

Well, sometimes it’s useful to have a “phantom” channel that isn’t actually patched into anything. When a particularly demanding performer rushes over during a show to ask for more “this” and less of “that” try giving them a big, cheerful thumbs-up and let them see you making an adjustment on the phantom channel. You’ll be surprised how often this can have beneficial results. They’ll nod that it’s made a difference – they’re happy.

Are you tricking them? No. Are you being dishonest? Not really. Are you being a wanker? No, but by then at least the astute foldback engineer will have established that someone is…
