A versatile mic at a
righteous price
Blue makes fine mics—whether
you’re talking specs or industrial
design. Although the company built
its reputation on high-end mics,
Spark takes its condenser know how
into a lower-priced world.
One Size Fits All
Spark seems designed so that if
someone could only afford one
condenser mic, they’d choose
Spark. It’s a medium-diaphragm
cardioid design with subtle
response tweaking—a small lift
around 11kHz (which brings out
the clean, responsive high end) and
1kHz, a bit of a dip in the “mud”
frequencies around 400Hz, and
another slight dip around the 2kHz
“honk” frequency. All of this is
ideal for vocals. A boost around
90Hz can emphasize the proximity
effect, or be tuned out with Spark’s
unique “Focus” switch, which
reduces bass and tightens the
lower mids
Focus isn’t a standard low-cut
filter; it alters the capsule’s voltage
loading rather than processing
the mic’s output, thus affecting
both dynamics and frequency
response. The effect is both subtle
in that it retains the mic’s desirable
characteristics, and striking in that
it can make quite a difference with
some sound sources. For example,
switching Focus out with vocals
gave a full, deep sound, but I had
to be careful about plosives and air,
even when using the included pop
filter. With Focus in, the vocal cut
more, minimized plosives, and had
a “direct” quality. With acoustic
guitar, switching Focus in helps
control “boom” if you like miking
close to the sound hole, while
switching it out sounded best
when I backed the mic off for more
room sound. It’s almost like having
two separate mics, increasing the
overall value considerably.
A Class-A Act
The solid-state electronics are
Class-A, which eliminates crossover
distortion because there is no
crossover, and handle SPL levels
up to 128dB. But, the mic package
as a whole is a class act. There’s an
industrial-strength shock mount
(improved over earlier versions) and
semi-effective pop filter, included
with the mic in a sweet wooden case
(Figure 1). Also, the manual goes
beyond just documenting the mic,
and provides helpful miking tips.
If you prefer hand-held rather
than shock-mount, at 1.25 lbs.,
the body feels substantial, yet fits
comfortably in any size hand. It
seems no more prone or immune
to handling noise than any
comparable mic.
Conclusions
At a below-$200 price, you’d
expect compromises, yet the
transient response and clarity
excel, without the high-end
“brittleness” sometimes
experienced with low-cost
condensers. It’s a sensitive mic—
you have to be careful about
“swallowing” it, and there’s a
reason why it includes a pop filter
(although you’ll probably want a
heavier-duty one on call)—so it’s
important to experiment to find
the right mic positioning. That
sensitivity is an asset, though, if
you like to move the mic back a
little bit to give more “breathing
room” and pick up a shade more
room ambience.

Fig. 1 Spark comes with a pop filter, shock mount, groovalicious wooden case, and helpful documentation.
If someone said they could
afford only one condenser mic, I’d
recommend Spark not just for the
versatility, but the quality. If Blue’s
goal was to produce the VW of mics,
I’d say they succeeded—except that
it’s the Turbo Diesel model.

STRENGTHS:
Clean, transparent
sound, with slight but
effective response
manipulation. Focus
switch adds value and
versatility. Improved

many types of signals.
Striking look and
packaging.
LIMITATIONS:
Pop filter lacks
effectiveness with
close-miking.
