Speck Electronics Model ASC Description
Jensen transformer option equipped model.
What is the
ASC?
The Model
ASC is a professional single channel 4 band equalizer in a 1/2 rack format. It
is simple...it is useful...and it delivers the high quality and specifications
found in all Speck Electronics gear.
That
Classic Sound
You'll hear
none of the thinness and edginess experienced with some other outboard EQ
devices. The Speck Model ASC is reminiscent of vintage equalizers, revered for
their dynamic range and musical performance.
The Front
Panel
This
compact 4 band parametric equalizer has 12 controls for equalization adjustment
that covers the audio spectrum from a low 20Hz all the way up to 25kHz. There
is a - 12/+6 dB gain control that handles the level variations when patching
between balanced and unbalanced gear. A bypass switch silently removes the
equalizer from the audio path.
The Rear
Panel
Connect the
ASC to virtually any line level source: balanced, unbalanced, or mixer inserts.
The Model ASC has high headroom that will handle balanced signals up to +28dBu.
To enhance the classic EQ experience, the Model ASC offers balanced transformer
and active balanced outputs.
4 Sweepable Bands
-
L Band: a low band that incorporates a
"Simulated Inductor" (si) design that sweeps the low frequencies from
20Hz - 150Hz. This band offers a Peak/Shelf select switch.
- L/M Band: a switchable low and mid band. This
fully parametric section can be switched between a low frequency band that sweeps
from 40Hz- 800Hz, or a mid frequency band that sweeps 400Hz-8kHz. This band has
a variable bandwidth adjustment.
- M Band: a fully parametric mid band with a
frequency sweep range from 400Hz to 10kHz.
- H Band: a high band that also incorporates
a Simulated Inductor (si) circuit that adjusts the high frequency from 4kHz
all the way up to 25kHz.

EQ Review / See
All ZenPro Audio Reviews Here: Review Page
The Speck ASC and ASC-T (“T” =
Jensen output transformer equipped, giving you the choice between active
balanced and transformer balanced outputs) 4 band equalizers have been around
for a long time for a reason: they do the job very well and are built to last a
lifetime by a guy who has been building gear since the early 70’s, Vince
Poulos. If you’ve ever met Vince at a trade show and talked with him at all
then you know, he’s likely one of the nicest guys in boutique pro audio and
knows what he’s doing and stands behind his work. His utility approach gives us
very specific devices for very specific jobs without too many bells and
whistles.
The ASC is super versatile in many
ways. First of all, it’s not really a “character” EQ in that it tends to stay
quite clean and isn’t in the business of drastically altering the tone. There
is a switchable low / low-mid band that is incredibly useful, say when you want
to use the dedicated low band as more of
a hi-pass but still need to bring it up in the right registers. Just hit the “low”
switch from “mid” and now you’re working with 40hZ to 800hZ, rather than 400hZ
to 8kHz. Now that is control, and control of the toughest region to get right.
Or think about sculpting a kick drum, you even have overlapping bands at 400hZ
(the “gut” range for me most times…) if you really need to carve up the low and
low mids. The dedicated low band is switchable between bell and shelving style
also. Both the low-mid and hi-mid bands have fully parametric control
(adjustable bell width). Now how about a top end shelf that extends to control
of up to 25kHz? Serious air can be delivered, again in a clean manner that
doesn’t get harsh but remains open and smooth.
The ASC-T model gives you two
outputs to choose from, active balanced and a high quality Jensen output
transformer that adds a subtle “sheen” to things and offers a bit of a
character choice (as well as what transformers do well which is rejection of
noise by design).
Conclusion: All purpose, excellent
sounding and a “can’t go wrong” EQ that won’t overly affect your tone, the ASC
and ASC-T models deliver high quality sound and are made in the USA and built
to last.
