Less Is More? Do Fewer Channels And An Acoustic Performance Make For An Easier Gig?

Mixing a small number of channels while retaining the full frequency spectrum, intimacy, and dynamics may be the pinnacle of the craft.

EQ With A Scalpel

Keeping as much of the frequency spectrum as possible of all sources in an intimate-sounding performance is key to conveying the artist’s energy from the stage to the audience. Make sure that EQ cuts are only as narrow and as deep as they absolutely have to be. Removing large parts of a sonic image will lead to an underwhelming sound and usually won’t support the intimacy of the conveyed message.

I try to have the performer sing softly, close to the mic, and apply a high-pass filter with a shallow slope (if that option is available on the console). This helps ensure that the proximity effect will not produce any “boominess” or feedback issues, but it’s important to make sure that the low end is still present.

Next, I focus on intelligibility, adjusting the 2 to 7 kHz range to taste, and then listen for the “annoying” frequencies and apply cuts, making sure this is as precise as possible. I always try to keep in mind that there are very scarce resources for filling in the cuts.

Imagine The Space

Selecting the right ambient sound for an intimate performance is a deal breaker, and it’s almost always left at the discretion of the mix engineer. I usually prepare a few options in advance that help me decide what’s best for the given performance.

“At least in my experience, intimate performances actually require quite a bit of support from the engineer throughout the show.”

Spatial decisions are based on one fundamental principle: does the space support the intention of the performance? Is the artist going for that “playing for a few people down the pub” vibe or trying to lead the audience to an imaginary palace of magic and fairy dust? Whatever it may be, being able to enhance that energy and intention is crucial.

My effects suite for small-channel-count performances is almost always the same: a room reverb, a plate reverb, a cathedral-type reverb, and a delay unit. The room reverb is for fill-in for those moments of the show that are particularly intimate and personal. It’s added at a level where its presence can only be discerned if it were turned off, but it can’t necessarily be heard on its own.

Sometimes, equalizing this room verb also acts as an additional master EQ parameter. For example, if more low mids are needed, I can just add them to the room verb instead of the master EQ or individual channels.

The plate/hall verb is the one that can actually be heard. I almost always have the decay set between 1.3 to 2 seconds, but I also make sure that the pre-delay is set to at least 80 milliseconds. Using a longer pre-delay helps retain the intimacy of a vocal or an instrument while still developing a nice space around it. Sometimes I remove the delay from the FX chain and just play with the pre-delay on this verb to get that “one-time-repeat” delay feeling.

The cathedral-type verb is an option that I add to certain songs or moments in a performance to open up the sonic space and make it more “dreamy” or “magical.” The decay times are usually over 4 seconds, but as with the room verb, it’s never overpowering. It’s like a delicate spice in a dish, adding an extra dimension that helps the artist convey the message.

About 90 percent of the time, I EQ the verbs quite dark, with a low-pass filter set low, usually between 2 and 3 kHz. To me, intimate performances need to sound natural and a bright sounding reverb can destroy the illusion of listening to a performer up close and personal.

The delay unit comes on for certain songs, but only if I can make it blend with the rest of the space. To do that, I always run the send from the delay unit into the plate/hall reverb aux, just to make the repeats more a part of the imagined space and not having them break the illusion. Again, as with reverbs, removing the top end of the delay can help in maintaining the soundscape, making sure nothing is shifting the focus of the listeners away from the initial source.

Fader-Riding Messenger

So, if the overall intention is to create the illusion that the performer is sitting intimately in front of the audience, how much action is required on the part of the engineer throughout the show? Surely if everything is set correctly then the act should be able to perform without the engineer riding the faders and adjusting parameters throughout the show, right?

Well, at least in my experience, intimate performances actually require quite a bit of support from the engineer throughout the show. However, I hasten to add that these changes are usually minute corrections. Riding the faders should be in support of keeping the dynamic range intact and ensuring that all possible nuances are heard. My initial fader positions are set at 0 dB, which helps ensure maximum control over fader movements, and then whatever I do with levels never sounds unnatural or harsh (except when the performance demands it).

At a recent show, I was working with an acoustic band that wanted to have moments of sounds rising to levels that were almost uncomfortable for the audience, only to resolve them with very intimate and quiet passages. Although making sure that it was not unbearable, I supported those “noisy” moments by pushing the faders up while also enhancing the dynamic range and helping the act convey the message, which is the point of all of these techniques.

But the underlying principle is the most important one: do whatever is needed for the song and performance to convey the intended meaning from the stage to the ears (and hearts) of the audience.

Although this applies to all shows, the ones with small channel counts usually need that support the most. Because there’s far less material to work with in terms of channels, there’s no place to hide – every decision you make will be displayed for all to hear.
