What’s a Levelling
Amp? Clearly, we’ve decided to
distinguish our RNLA from our RNC by calling it a “levelling amplifier” instead
of “Son of RNC” or “RNC II” or some such thing. Without being too geeky about
it, we decided to call it “RNLA” for two reasons:
1) The RNLA has a sonic signature
similar to many compressors that we’ve used over the years, many of which have
been referred to as “levelling amps”(e.g., LA2A, LA3A, etc.). (DISCLAIMER:
Please don’t confuse this with us saying that the RNLA sounds just like
such-and-such, ‘cause it doesn’t and that’s NOT what we’re saying!) There are
some sonic similarities—a “classic” character, if you will—between the RNLA and
some of the more preferred, sought-after levelling amps and opto compressors.
Some well-outfitted RNLA users report that even with a full complement of
expensive, vintage levelling amps/compressors, the RNLA still fills a niche that
the others don’t!
2) It allows us to call the
RNC/RNLA by names that are as distinct as the sounds they produce. The RNC was
designed to be somewhat neutral while the RNLA was designed to deliberately
color the sound.
What’s cool about the RNLA?
Before you
run off to work on your next hit record, I want to point out to you some of the
salient points about the Really Nice Levelling Amplifier
that may not be overtly obvious and, yet, may be important for you to
know:
Wide Dynamic Range -
Despite the unbalanced
input/output connections, the RNLA has a dynamic range of 117dB, minimum, which
is appropriate for today’s digital systems and exceeds that which is attainable
with many older, “vintage” levelling amplifiers. The RNLA offers a clip point
(<3% THD) of 22.5dBu.
Fidelity
- Although the RNLA is designed to dynamically “color”
the sound passing through it, the channel electronics are fairly neutral and
designed so that the output signal (statically measured) closely resembles the
input signal (fidelity defined...though slightly
paraphrased). Each channel is hand-trimmed to typically less than 0.005% Total
Harmonic Distortion plus Noise (THD+N). Even this lowlevel distortion is
predominantly second-order...a much less heinous form of distortion and agreed
by many to impart a slight sweetness” to a signal.
Ugly and
Cheesy Box - Like its FMR brethren, the RNC and RNP, we
use a third-rack cabinet (still a hearty combination of extruded aluminum and
steel) to allow us to throw the money we save in cosmetics into the quality of
the audio electronics. Although we did decide to splurge a little by putting
very red knobs on it along with a brushed-aluminum
Lexan™ overlay for that more impressively cheesy, “homegrown”
look!
Easy-to-read Panel Graphics - This may seem like
an arbitrary and trivial point, but we think it’s important: easily assessing
the settings on a rack-mounted processor is important when you’ve got a lot of
stuff going on during a recording session. In our experience, dark lettering on
a light background works better than the other way
around.
Inputs
and Inserts - As with the RNC, the RNLA has unbalanced
inputs that also double as Tip-Ring-Sleeve (TRS) inserts to mate with popular
mixer and equipment inserts. This allows you to connect an RNLA’s channel (in
& out) to a mixer or other compatible device (such as our own Really Nice
Preamp, Great River Electronics MP-NV preamp, etc.) using only a single
TRS-to-TRS cable per channel.
Balanced Outputs - T he
RNLA has balanced, non-differential outputs. Although the “cold” part of
the signal is not driven (that would be a “differential” signalling scheme), the
impedance in both legs are the same, thereby giving your audio the
benefit of reduced noise IF the RNLA is
connected to a balanced line input.
Precise Gain Reduction
Metering - A highly accurate
gain reduction meter is provided to allow visual verification of
what you’re hearing. Although meters should never be a substitute for what you
hear, a dynamically accurate meter is better than one that can “lag” or misread
the actual dynamic performance of the compressor. Due to our
digitally-controlled architecture, peak-detection errors are greatly reduced.
This makes for a very accurate meter.
Full Parametric Control -
Some of the more common Levelling
Amplifiers don’t have full parametric control. Many LAs are missing the ability
to control the ATTACK time. Some of them don’t even provide a RATIO control, let
alone a continuously-variable RATIO control! The RNLA provides both for maximum
artistic flexibility. But, most importantly, both the ATTACK and RELEASE controls go to
11! In addition, all of
the front panel controls are merely a “control surface” for the RNLA’s internal
digital engine. This means: (a) No main channel audio flows to/from
the front panel controls that might increase its noise susceptibility (that’s
bad) or dreaded “scratchy pot syndrome”
(that’s annoying ), and, (b) We can use
a “ratiometric” measuring technique, along with robust digital filtering, to
derive repeatable and precise compression parameters (that’s good, if not a
little geeky). Did I mention that the ATTACK and RELEASE controls both go to 11?
Alternative Release Contour - Loosely based upon the “Log/Lin” control on the
Valley People’s (Person’s?) Gain Brain II, this control (“Log Rel”) can help
restore some “punch” that can get lost without an acceleration of the release
envelope. So, when Log Rel
is on, we accelerate the release
time as a function of gain reduction amount. We’ve found this to be particularly
handy on drum sub-mixes where we still wanted the drums to “punch”, but in a
compressed and controlled way (you know, it’s really true: talking about
audiois like dancing about
architecture... ).
Hardwired Bypass -
We use a sealed relay (for long
life) to switch the RNLA’s output connectors between the output of the
compression stage or the input jacks, thus providing a true bypass of the signal
path. Worst case, without mains power, you’ll still get a signal out of the
RNLA!
Made In The U.S.A. -
We want you to know that we do our
own manufacturing here in beautiful Austin,
Texas ‘cause: (a) We live here. We’re control freaks. We need things done to
standards that are very specific and loftier than most.
Manufacturing products here help control important costs and reduce waste
(there’s more to producing a product than just considering the costs of labor
and parts). All this helps ensure that your RNLA will retain its value and
continue compressing for many years to come, (b) Austin’s resources and
culture—from a very lively music scene to lots of high-tech
companies/products—help inspire and maintain our commitment to music and
technology, and, (c) In order to help others, here and abroad, we believe we’ve
got to be vital and capable ourselves. Our first choice is to employ as many
U.S.-based resources as possible in the design, manufacture and distribution of
our products.
What sucks about the RNLA?
The first time I
included this What Sucks!
section was in the Really Nice
Preamp (RNP) manual. It had the desired effect: our customers (i.e., those who
“get us” and our products) really like—actually, based upon their responses,
downright appreciate -
having a first-pass
assessment of our product’s strengths and weaknesses even if it’s from the
product designer’s view. So, here’s to you, our dear customers! (drumroll
please!) We continue this new-found tradition and present What Sucks about the RNLA...
The RNLA uses a wallwart -
As with our other products, the RNLA
uses a wallwart. This is done to: (a) reduce internal noise induction, (b) make
the national/international regulatory compliance less costly, and, (c) to permit
easy adaptation of the RNLA to countries other than the U.S.A. As practical as
these reasons for wallwart use are, it doesn’t reduce the annoyance factor that the RNLA uses a less common, *AC* wallwart. You
can reduce this annoyance, however, by:
(a) labelling your wallwart on
both ends (i.e., on the part that plugs into the wall and at its opposite end)
that the wallwart is for use with the RNLA, and/or,
(b) use AC mains power strips
that can accommodate the extra space required by wallwarts, and/or, (c) hook-up
your wallwarts with one of those short, power cord extenders. In either case,
what a pain wallwarts are...
The RNLA “colors” the audio -
I don’t consider myself a “purist”,
however, Ihave
spent a fair amount of time/effort
in the studio (and design lab) trying to reduce sonic coloration (i.e.,
distortion). Although I appreciate and applaud those who are skillful enough to
record and mix with fidelity or colorationat will , I’ve always preferred fidelity over distortion...no
matter how artsy it is! So, why are we now producing a device that
deliberately distorts the audio? There are three reasons for this:
(1) our customers have requested it and feel that they can’t get
specific combination of features elsewhere, (2) I believe that the RNLA
distorts in a tasteful, useful and controllable way, and, (3)
Maybe you can teach an old dog new tricks: I’m
actually learning to like and find uses for the sonics of the
RNLA!
The RNLA has freakin’ RED
KNOBS - Proof, once
again, that there’s “no accounting for taste”, I specified these
knobs after a word-association game with my therapist. Here’s an
excerpt:
Therapist: Dog?
Mark: Compressor(?)
Therapist: Cat?
Mark: Compressor(?!)
Therapist: Red knobs?
Mark: Levelling amp! (???)
Okay, I made that up, but it could have happened! In any case, for those of you who are color-blind (or
not) I apologize...
