Speck Electronics Model ASC-V Description
What is the ASC-V ?
The ASC-V
is a professional single channel 4-band equalizer in a 5.25 vertical module
compatible with API Audio® 500 series rack frames. It is simple... it is
useful... and it delivers the high quality and specifications found in all
Speck Electronics gear.
This compact
4-band parametric equalizer has 12 controls for equalization adjustment that
covers the audio spectrum from a low 25Hz all the way up to 25kHz. To enhance
the classic EQ experience, the ASC-V offers both transformer-balanced and
active-balanced outputs.
4 Sweepable Bands
- L Band: a low band
that sweeps the low frequencies from 25Hz - 400Hz. 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 adjusts the high
frequency from 2kHz all the way up to 25kHz. This band also offers a Peak/Shelf
select switch.
The Rear Panel
In addition
to the standard rack friendly edge connector, the ASC-V has a set of 1/4"
TRS input/output jacks, and a power input connector. With these I/O connectors
and the optional power module, you can ignore the PC edge connector and use the
ASC-V as a stand alone EQ.
We even offer a mounting
base that will hold a single EQ or a pair of the ASC-V's.
Connect the
ASC-V to virtually any line level source; balanced, unbalanced, or mixer
inserts. The Model ASC-V has high headroom that will handle balanced signals up
to +28dBu.

EQ Review / See

The ASC-V version offers switchable bell / shelf on the hi-freq band and runs on API 500 series power supplies.
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.
