9.8.5 System Alignment Rules
The visual result of a sound-system test can be a powerful tool;
however, like any powerful tool, you must be responsible about
how you wield it. Here are few basic principles to follow:
Solve the problem at its source. The closer to the source, the more eective
the solution will be. If your kick drum lacks punch in the mix, take a look
at the kick-drum channel’s EQ and dynamics processing. Is the kick drum
properly tuned? Are you boosting the attack of the kick beater enough
and at the right frequency? Is your compressor’s attack too long?
Use the right tool. The system EQ is the last in a long line of possible solutions
to frequency problems. Once you have fully assessed the problem, you
can choose the right tool. Check the acoustic space, choice of equipment,
and system design rst. Obviously, you don’t always have control over the
acoustic design or treatment (or lack thereof) of a room, and your wallet
might determine your choice of speakers more than your needs do, but
usually you have some control over your sound system’s design.
Can you raise the speakers to mitigate some of the harsher
reections? What about widening the stereo eld?
After you’ve ruled out physical solutions to a sound problem, move on to level and
delay. Can you simply lower the level of your subwoofer to kill some of the boom
in the room? Can you delay your front-of-house speakers by a few milliseconds
so that they’re in alignment with the guitar cabinets blaring from stage?
If you can’t nd a physical solution and can’t mitigate the issue with
level and delay control, it’s time to employ the system EQ.
A frequency-response trace is not a video game. Your goal is to x your
system and make it sound the best it can, not create an EQ curve that is an exact
inversion of the frequency-response trace. Mix with your ears, not your eyes.
An analyzer is a tool; you are the carpenter. You decide where
to measure your speakers. You decide what the resulting data
means. You decide what (if anything) to do about it.
9.8.6 Using the Trace: Spotting the Trend
As discussed in the previous section, many factors can aect the response
of a sound system: the room, system conguration, electronics, wiring, and
more. Part of understanding what you see is knowing what you should
not be seeing—or at least having a basic idea of what to expect. After
all, you are trying to sculpt the EQ curve of the system into something
that compliments that sound system’s frequency response.
For example, a small system without a subwoofer can’t reproduce much energy
below 50 Hz. In fact, this frequency cuto could be even higher, depending
on the size of the speaker, its factory tuning, porting, etc. This means that
if you are analyzing a system that is comprised of two 2-way, 12” powered
speakers, you should expect your frequency-response trace to drop o
around 50 Hz or so (depending on the frequency response of your speakers).
Because of this, boosting low frequencies in this type of system wouldn’t
achieve much and may introduce more problems than it would solve.
