Recording - December 2015 - 41
But engineers, never satisfied, wanted more flexible and precise control over the sound and
atmosphere of each mic. The American answer was to adapt equipment designed for the
phone company (the famous Pultec MEQ EQs, with passive equalizing circuits and tube
makeup gain) and the movie industry (Cinema Engineering passive EQ boxes). The boffins
at EMI, meanwhile, developed a gadget called the Curve Bender. They built precisely one of
these, and would wheel it from studio to studio at Abbey Road, as needed.
These devices offered a type of equalization new to the record industry, peak-and-dip EQ.
A peak-and-dip equalizer allowed the engineers to boost or cut a narrow band centered
around a particular frequency, which was selected using a multi-position switch. You can build
a hardware version of this type of equalizer, designed by our own Scott Dorsey; construction
information is posted on Recording's website at http://is.gd/RECDIYActiveEQ. It does frequency selection using capacitors and coils; because some of the coils Scott specifies behave
in a nonlinear fashion, meaning that they distort the signal in ways that sound interesting, this
hardware box doesn't sound like any software EQ I've heard.

When I said earlier that hardware and software sound alike, mostly, I had boxes like Scott's
in mind for the "mostly" part. Some companies, like Universal Audio, have designed plug-ins
that mimic similar nonlinearities in classic hardware EQs. Our reviewers report that they deliver an excellent simulacrum of the hardware units' sound. But I digress.

EQs with switchable peak and dip frequencies were all very well, but recording engineers,
as usual, wanted more. They wanted the frequency control to be a continuous sweep, rather
than a switch choosing between fixed frequencies, so they could zero in on a problem frequency and turn it down or up. And they wanted control over the shape of the peak or dip.
Design engineers came up with some clever circuits which did just that, and the word "surgical" began to be heard in control rooms around the world.
Shape controls altered the bandwidths of the peaks and dips, but that's not how they were
labeled. Here's why: a peak or dip with a bandwidth of, say, 300 Hz takes a big bite out of
the spectrum if its center frequency is 1 kHz, but if the center frequency is 10 kHz, a 300Hz
peak or dip is more like a sliver. Instead, the knobs were (and are) calibrated for the mysterious-sounding Q. This is nothing more than the center frequency of the peak or dip,
