Black Lion Audio AM/CHA1 Equalizer Description
Go hear it now in our Clip-A-Lator test page!
We're all fans of inductor based EQ. While it doesn't offer the
surgical precision of its solid-state based gyrator circuit cousin, it
has a wonderful musical quality that's very natural sounding. Typically a
good inductor EQ has, in the past, been rather expensive to purchase. A
classic API or Pultec-based EQ will set you back a few thousand dollars
for a stereo pair.
Since we enjoy a good challenge, our goal was to develop a transformer
coupled two channel inductor based EQ that could perform every bit as
well as a high priced mastering-grade setup, but do it at a lower price.
Since there are lots of Pultec clones out there, we wanted do develop
something that was unique. We based it on what's known as a
state-variable filter, and built it around custom wound Cinemag
inductors. We gave it overlapping frequencies within each set of
frequency bands to enable flexibility and frequency correction when
needed. We use the same grain oriented silicon steel transformers in the
input and output stages to give the audio a nice vintage character,
although amorphous core Lundahl transformers are available as an option
for an additional charge.
And since we have access to a few mastering-grade inductor EQ's, we
tweaked and refined the circuit until we were satisfied that it was
every bit as good as the expensive brands. The smooth highs, natural
mids, and thick, powerful bass that only a good inductor EQ can deliver.
Go ahead; shoot it out against your Neve, Massenburg, API, or Tube
Tech. We think you'll be very impressed.
