RØDE Classic, April 1997


When I first heard that Australian company RØDE was offering a
multipattern, large-diaphragm tube condenser mic for only $1,999, I was a bit
skeptical. The cost of manufacturing a quality vacuum tube microphone
is usually very high. So how good could the modestly priced RØDE
Classic be? Very good, it turns out. The RØDE Classic’s
audio quality and construction are both top-notch. And, considering its
low price, the package includes a surprisingly generous allotment of
features and accessories.

The RØDE Classic is quite retro-looking. Its almost perfectly
cylindrical shape and unadorned nickel finish are reminiscent of
vintage European tube microphones. The mic’s beefy size
(approximately 7×2.75 inches), hefty weight (more than 2 pounds) and
quality construction make a very favorable first impression. The
hand-polished, solid brass body is fitted with a small, gold-plated
Tuchel connector for the remote power supply. A very sturdy, wire mesh
head grille is supplemented by a finer internal pop screen and an
internal shock-mounting system for the capsule.

The hand-assembled capsule is mounted in a side-address orientation
and features 1-inch, gold-sputtered, dual diaphragms that are 6 microns
thick. The Classic’s shock-mounted GE 6072 vacuum tube is matched
to an internal, Mu-metal cased output transformer that was
custom-designed by Jensen. There are no switches on the mic body, and
all adjustments are made remotely from its external power supply. A
small, gold, slotted screw just below the head grille is the only
visual clue identifying the front of the mic. It’s a very minor
niggle, but an otherwise identical silver screw adorns the back of the
mic, making correct setup in low light a rather squinty-eyed task.

A thickly jacketed, custom-made, 10-meter multicore cable mates the
RØDE Classic to its remote power supply via gold-plated Tuchel
connectors. I’ve had occasional problems with Tuchel connectors
getting stuck on other mics, but the ones on the RØDE Classic
unscrew and pull out easily. Besides providing a bomb-proof connection,
Tuchels also offer superior RF rejection.

The RØDE Classic includes a full-featured, remote power supply
and a generous (eight-plus feet long), detachable AC cord. Three large
knobs on the front panel control the mic’s polar pattern, bass roll-off and padding,
respectively. Polar patterns are adjustable from omni through cardioid
to bidirectional in nine steps (achieving intermediate patterns along
the way). The three-position highpass control selects flat response, or
-6/-12 dB/octave
roll-off of bass frequencies at 125 Hz. The mic can be padded 10 or 20
dB, or left unattenuated. A large, red front panel LED lights when the
supply is powered up, which is good, as the on/off positions of the
rear-panel power switch are unmarked. Audio output is via a standard
3-pin XLR (pin #2 hot)
on the rear panel.

Amazingly (considering the price), the RØDE Classic also has a
beautiful, foam-lined, aluminum flight case (lockable, with keys) for
storing the system. In fact, the only items lacking are an external
foam pop filter and external shock mount. A “naked” Classic
can pop on a breathy singer, but a Popper Stopper stocking screen
solved the problem. And although the Classic is a little susceptible to
rumble, the highpass
cures any problem nicely without throwing the baby out with
the bath water. Both the highpass filter and polar pattern controls
switch positions silently. However, changing the pad setting causes a
loud pop in the audio path.

Mounting the Classic to a mic stand is simple. A large, knurled nut
secures the mic to a sturdy L-bracket, which mounts in turn on top of a
mic adapter. The circular nut can be loosened to allow the mic
virtually 360° of rotation about a horizontal access, greatly
easing accurate placement (and allowing you to hang the mic upside
down). One caveat, though: the mic’s considerable weight does
tend to make it slip out of position if you don’t secure the nut
with a very firm twist.

Nothing out of the ordinary here. Sensitivity is a capable 13 mV/PA,
maximum SPL is 130 dB (150 dB with the 20dB pad). The broadband
self-noise spec. of 24dB is fairly typical of tube mics but does prompt
some caution for critical applications—the Classic can be a tad
noisy on exposed sources such as classical harp and wind chimes.

Like most multipattern mics, the Classic offers many timbral
possibilities. The frequency response is quite flat in the bass and
midrange, and never more than 3 dB down at 20 Hz for any polar pattern.
Response at 20 kHz is only 2 to 4 dB down, depending on the pattern
chosen. As is usually the case, Figure-8 mode has the least amount of
“top,” though it’s by no means dull-sounding at
0° on-axis. In all other respects, it’s the flattest of the
patterns offered. Omni mode has a slight, smooth dip in the upper mids
around 2 to 3 kHz and a hefty 6dB boost centered around 11 kHz.
Cardioid mode exhibits a broad 2dB boost in the upper midrange, rising
moderately to 4 dB around 11 kHz.

All of my critical listening tests (and overdubs) were performed
with a Millennia Media HV-3 mic preamp, chosen for its neutrality and
extreme accuracy. The Classic’s off-axis response is outstanding,
with one exception. In Figure-8 mode, close-miked sources 180°
off-axis had a lot more low midrange content than sources miked 0°
on-axis at the same distance. This makes it difficult to find the right
balance on opposing background vocalists, although one could always use
omni mode for this application. On the positive side, the rear side of
the mic in Figure-8 mode yields by far the thickest (if not the
blurriest) sound of all, which can be very useful when trying to add
support to extremely thin or nasal instruments.

Miking male vocals in cardioid mode at seven inches, the Classic
sounded warm and lush with rich texture. The mic has both a big, fat
bottom and an articulately detailed high end. If you’re looking
for a mic with plenty of tube “splatter,” you won’t
be disappointed—here, the Classic really delivers. However, the
mic has a somewhat full lower midrange that can make it a tad cloudy on
inherently woolly-sounding vocalists, who would be better served by a
more open mic such as the AKG C-414TLII. This is not a criticism; I
could say the same thing about the C12VR, U87, etc. That’s why
every studio stocks a variety of mics for different singers.

I got similar results miking a husky, alto female vocalist. Spoken
word sounded awesome—big, detailed, tonally balanced, 3-D and
lush with pleasing harmonics. When she sang over a dense, busy mix,
however, the Classic sounded a tad cloudy. The singer’s natural
sibilance was also a little emphasized by the mic. Unfortunately, I
never got to hear the Classic on a soprano vocal, but I would hazard a
guess that it would probably fatten it up nicely.

Next up: a Fender Strat played through a Mesa Boogie Subway Rocket.
The Classic was put in bidirectional mode, about 45° off-axis and
20 inches from the cabinet. This sounded downright
awesome—creamy, fat, rich and detailed, with the perfect blend of
thick body and raspy cut.

In cardioid mode on classical harp, the Classic demonstrated
outstanding transient response. The tonal balance was very pleasing,
with both a bright, vibrant top and deep, full bottom. The sound was
considerably lusher and fatter than that provided by my B&K 4011s,
though the latter mics were chosen in the end for their open upper bass
and superior signal-to-noise. The Classic’s self-noise was a
little obtrusive during quiet passages on this most dynamic of

Noise was also a problem on wind chimes. But if it’s possible
for wind chimes to sound fat, then the RØDE Classic is your ticket
to obesity. Simply put, I’ve never heard a more flattering mic
(from a timbral standpoint) on this instrument. The sound was full and
lush, yet sparkly and detailed.

Overall, the Classic is no noisier than a C12VR and exhibits better
RFI rejection. Interestingly, much of the Classic’s self-noise
(no, it was not transformer hum) lies in a broadband low-frequency
region, where it can easily be rolled off on background tracks, chimes,
etc., for perceptibly better noise performance.

Finally, we take a vicarious trip to India for overdubs of sruti box
(similar to harmonium) and tamboura. The Classic is a great mic for
sruti box, lending a rich and full—yet present—sound. And
the tamboura sounded absolutely incredible. Here, the Classic perfectly
balanced the sonorous, low-end drone of the instrument’s body
against the rich, tangy buzz of the strings. The pluck of the strings
was also very faithfully reproduced. The power supply’s
switchable highpass filter removed excess low-frequency thumping in the
string attack without robbing the instrument of its warmth and

The RØDE Classic is the richest and biggest-sounding mic
I’ve heard in its price range. It imparts gobs of rich tube
luster to whatever it touches, and its unusually good transient
response (that is, for a large diaphragm mic) makes it a very versatile
performer. The Classic’s only limiting factor is its self-noise
level, which is about average for a tube mic. While noise won’t
be an issue in most situations, it could be a problem in critical
applications such as classical or a cappella recording. When you weigh
the Classic’s beautiful tonality, tight off-axis response, beefy
construction, generous feature set and quality flight case against its
modest asking price, you can only draw one conclusion. It’s a
