Hands-On Product Review:
Fishman Aura Spectrum DI
An entire spectrum of sound for your acoustic guitar
By Darius Van Rheuhl
There’s
being serious about your acoustic sound, and then there’s being Fishman
Serious. People who fall into the latter category are on a never-ending
quest for better sound—much like Larry Fishman himself, who, while
searching for a good-sounding pickup for his beloved double bass, found
himself on a journey of discovery that led him up and down the East
Coast and ultimately back to himself. The discovery was the old cliché,
"If you want something done right, you have to do it yourself." And that
happy accident is how Larry Fishman became the top name in acoustic
amplification, when all he was looking for was a way to have his bass
heard alongside electric instruments. Still on the same quest for the
ultimate acoustic-electric sound, Fishman’s latest advance is the
Aura Spectrum DI ; an eye- and ear-catching pedal that combines a
high-quality DI/EQ/compressor with breakthrough Acoustic Imaging
technology.
What’s in your Aura?
Beyond its understated elegance and solid
build, you don’t have to be psychic to see there’s something very
special in this Aura. Though the
Aura Spectrum was designed as a high-quality, balanced DI, it offers
so much more, including a three-band EQ; one-knob compressor; chromatic
tuner; automatic feedback suppressor with up to three notch filters;
effects loop with automatic ground lift for hum-free effects; a
convenient mute/bypass switch; and last, but miles from least, Fishman’s
remarkable Acoustic Imaging Technology. Think of it as an all-in-one
acoustic guitar processor. And with 32-bit resolution and 24-bit A/D/A,
the Aura Spectrum DI offers Fishman’s best sound to date.
If you’re not familiar with Acoustic
Imaging Technology, here’s a brief primer: It’s designed specifically
for guitars with undersaddle piezo pickups. Piezos are quite adept at
picking up the resonance of your guitar’s top and body cavity, but in
recording (or playing live), that’s not where all the magic happens. The
sonic signature imparted by certain mics and preamps capturing the
guitar’s sound as it blooms in a live acoustic space are the missing
components of said magic. With Acoustic Imaging, a guitar, chosen for
its combination of tone woods and body shape, is excited (vibrated) and
recorded in a beautiful-sounding space through a number of premier mics
and a high-end preamp. The resulting image is then processed along with
your guitar’s piezo output, adding back the acoustic components that
inject the magic into your guitar’s sound.
It’s all about having the
right Image
According to Fishman, the best results are
achieved by matching the Image as closely to your particular guitar as
possible. To aid you,
Aura Spectrum includes Aura Image Gallery software (PC only, with
Mac support coming soon), a downloadable library of over 700 Acoustic
Images. Simply enter the parameters of your guitar, including body type
and tonewoods, and the Gallery pulls ups the corresponding Images, which
you can download into the Aura Spectrum’s User Images bank via its USB
port. As an added plus, the Images aren’t limited to guitar. Other
stringed instruments include violin, mandolin, resophonic guitar,
bouzouki, and ukulele. Fishman also offers the ability to create custom
images for your guitar in their studio. Artists such as James Taylor,
Steve Earle, and Ben Harper have taken advantage of this unique
tone-boosting service.
Both ends of the Spectrum
As a DI with unique processing abilities,
I was curious to see if the
Aura Spectrum was better suited to live sound or studio chores.
There’s not a lot of gear out there that can do both equally well.
Starting with live sound applications first, I set up one of those
affordable mega-bang-for-the-buck mixers and powered monitors. I was
about six feet away from the speaker when feedback reared its rather
unpleasant-sounding extremities. Good a time as any to test the feedback
suppressor. Just by holding down the footswitch, it searched out the
offending frequency. I was surprised at how effective it was, and how
transparent-sounding the results were. With feedback under control and
lots of tonal options to play with, it wasn’t long before the Aura
Spectrum DI kicked the console’s performance up into big-boy territory.
Giving the one-knob compressor a whirl—literally—yielded interesting
results. Along with adjusting both threshold and ratio simultaneously,
gain also came up quite proportionally. My immediate reaction was, "this
will be really useful if you need to cut through an electric mix." Even
as a straight DI, the Fishman front end provided a noticeable
improvement over my mixer’s preamps (which weren’t all that bad to begin
with). I didn’t linger over the EQ—it did exactly what an EQ should.
Moving on to the recording end of the
Aura Spectrum. Lately, I’ve been recording a song that has an
acoustic guitar intro. I recorded a scratch track direct using my
guitar’s piezo pickup, and vowed to come back to it later on; which
meant lots of time choosing and moving mics, and then trying to
duplicate the feel of the scratch track, which I really liked. Initially
I recorded another take using the Spectrum just for some A/B between it
and an untreated direct piezo sound, but upon playback, discovered that
I didn’t need to bother with miking and re-recording my scratch track.
Now I have some pretty decent gear in my studio, but what I don’t have
is a $3,000 Millennia HV-3D preamp, 16 mics hovering in the
$2,000-$4,000 range (including Neumann, DPA, and Schoeps), and a
mega-bucks treated live room. But with the Aura Spectrum, I do—and so
can you. (If you guessed that’s the gear they use to record the Images,
you’d be correct). Using it as a re-amping device, I was able to keep
the feel of my scratch track with the added magic of Acoustic Imaging.
A full Spectrum cure
Going way beyond the functions of a
straight DI, the Aura Spectrum will add wondrous colors to your guitar’s
aura while allowing you to streamline your stage rig and bypass budget
console preamps. If you already have an Aura pedal and choose to
upgrade, you’ll be pleased to know that the image banks in the Aura
Spectrum are the exactly the same, so you can use your normal presets
and experience your preferred sound—and quite a bit more. If you want
the shortest path to a great acoustic studio sound without having to
sort out mic placement, preamp selection, and room treatment, the
Fishman Aura Spectrum DI is the most cost-effective solution I can
think of—and it’s always a big plus when you can find a cost-effective
product that works wonders in both live and studio environments.
