First of all, if you don’t understand what great music sounds like, you’ll struggle to build a great sounding mix. Your musical-balance instincts are guided by conscious or subconscious impressions and observations. As sound operators, we aren’t charged with simply archiving an event—we’re trusted to build a musical mix that has power, blended with intimacy and accessibility. Every excellent sound operator should spend a lot of time listening to music and analyzing its sound.
1. Consistent, Understandable, and Powerful Lead Vocals
It is job-one to make sure the leader is heard and understood at all times, whether he or she is singing or speaking—accomplishing this demands your constant attention. Compression can help keep the vocals in a narrower dynamic range but successfully keeping the lead vocal in the best space requires active mixing (adjusting the fader level). Learn to enjoy riding the flow of the lyrics and musical energy during a song. It’s not uncommon to cover a wide fader range in the effort to keep the lead vocal in just the right place.
2. Make Sure Speaking Parts Are Heard
When the leader is talking over the music, make sure he or she is heard—this is more easily accomplished by turning the band down than by simply turning up the leader. If the band is on a set of subgroups, simply turn those subgroups down a little while you boost the leader. Make sure that verbal directions and praise are heard—many strong singers lack support when they speak and can’t be heard without a substantial level boost. And, always remember to mute the effects returns between songs when the leader or pastor is speaking.
3. Balanced and Blended Backing Vocals
Balancing and blending the backing vocals is as important as balancing the leader. An out-of-balance harmony part destroys the impact of an otherwise powerful sound. Always be aware of the lead and backing vocal balances and blend. Personally, I prefer to keep the backing and lead vocals on consecutive faders under my right hand. When adjusting the rest of the mix, always be aware of the vocal blend.
4. Consistent Focal Point Throughout the Song
It’s very important to hold the congregations attention. As the mix engineer, it’s your job to control the focus—to build a mix that is undeniably easy to follow. Lead vocals provide the obvious focal point in most genres, but in the spaces between lyrics or musical sections, some mix ingredients need to take over, providing a bridge to deliver the listener to the next musical section. If your music team has spent the time and energy to construct strong musical parts, the focus will tend to flow naturally, but in many instances, the sound operator needs to skillfully create a focus by highlighting mix ingredients between vocal lines and so on.
5. Sounds Good in Stereo and Mono
This is a very common consideration for studio engineers, but many live engineers never think about the way a stereo mix collapses to mono. With the introduction of modern affordable digital mixers, more and more churches are capturing multitrack recordings of their music services and then remixing after the fact for distribution to the congregation. When building a mix, continually cross-reference the sound of your stereo mixes in mono to confirm that they sound good both ways. This is especially important for sound operators who work with mono live church sound systems. It is entirely possible to create a huge-sounding wide stereo mix that sounds small and very out-of-balance when played through the mono system. For a more in-depth study of this concept, refer to books 1, 2, and 6 of the Hal Leonard Recording Method.
6. Width
When mixing for a studio project, a stereo mix is more interesting if there are one or two instruments defining the far left and far right boundaries. Some sound operators ridicule the idea of a stereo mix in a live setting—I don’t. Even if all you do pan stereo effects wide left–right or pan the stereo synth and guitar processor outputs hard left and right, you’ve gained something. Both sides of the room hear the same balance but most of the room is treated to a wide sound with space reserved in the middle for the vocals, kick, and snare. It’s also helpful to slightly pan instruments such as acoustic guitars slightly off center.
7. Depth
A two-dimensional (left-right) mix is okay, but when a mix sounds three-dimensional (if the sounds seem distributed from near to far, as well as left to right) it becomes much more interestingly real-sounding. Reverberation and delays add depth—a very important part of a good mix. Most mixes should sound very large and impressive, yet somehow they must also feel very intimate and personal. Each mix must be shaped and molded to fit within the soundscape that projects the most realistic musical emotion for that specific song. Avoid adding reverberation to everything in the mix. Keep some ingredients intimate (dry) and others larger and more distant (wet).
8. Strong, Smooth Highs That Are Easy On the Ears
A mix that has one particular high frequency boosted on several instruments can take on an abrasive and irritating character. High frequencies must be distributed evenly.
Frequencies between 2.5 and 5 kHz can create a piercing, harsh, and edgy sound when exaggerated.
Frequencies between 6 and 9 kHz can add clarity without a harsh timbre.
Frequencies above 10 kHz add an airy quality to the sound with less of an apparent high-frequency boost.
If you need to boost the high frequencies on several tracks, combine cuts and boosts across the high-frequency spectrum to create an even dispersion of tones.
9. Mids Distributed Evenly Among Various Instruments
Midrange frequencies contain much of each sound’s character. However, too much midrange results in a “honky” sound, and too little midrange results in a hollow, empty sound. It’s important to control this frequency range. Midrange tones tend to help a mix sound blended and smooth; however, overly accentuated mids can cause a mix to sound dull and lifeless in the highs, or weak and powerless in the lows.
10. Strong, Solid, Yet Controlled Lows
It’s extremely important to build a mix that distributes low frequencies evenly. If the kick is boosted at 100 Hz, the bass should not be boosted at 100 Hz. In fact, most likely the bass should be cut at 100 Hz and, if necessary, boosted at possibly 60 or 150 Hz—this, of course, depends completely on the inherent sound of the bass. Low frequencies contain more energy than mids and highs, so exaggerated boosts can dramatically increase the mix level. Great sound operators pay close attention to this frequency band.
