It looks awesome, but what is
it?
Primarily,
it is a voice processor which in itself is not a novel idea, but the time had
come to pull out all the stops and make a truly professional high-end statement.
One that covered the needs of the project songwriters and big-time major studios
alike. One whose all-tube signal path could bring every instrument and overdub
to life. One that, plain and simple, sounded unquestionably better than the
rest, provided flexibility, simplicity, and well thought-out ergonomics. Full of
features, timeless style, robust build quality, and that world-famous
"Manley Sound", we present to you the MANLEY VOXBOX®.
That’s nice. What’s it
good for?
While
we were designing the VOXBOX® we couldn't help but notice how well it works on
other instruments besides voice. There are some great settings for drums,
bass, guitar, and keys and the two separate sections can be used together or
independently. Stereo using two VOXBOXes? You know we couldn’t resist
planning for that as well. There are Stereo Links for both the compressor and
the De-Ess/Limiter sections, special compression settings and super-sweet EQ
frequencies for your mix or pre-mastering. So don't just use it for voice. The
name "VOXBOX®" represents only the beginning...

MICROPHONE
PREAMPLIFIER SECTION:
The preamplifier is
a clone of a highly regarded and popular
mic pre: the Manley Mono Microphone Preamplifier! The mic input
transformer is our own
design wound in-house at the Manley Labs factory. High current 48V
Phantom power is
switchable from the front panel. A simple and effective passive BASS
CUT switch kills rumble
and reduces popping. The INPUT ATTENUATOR is a variable pad control
situated before the first
tube stage allowing the preamplifier to accommodate +4 line level
signals via the balanced LINE
INPUT and instruments via the front panel 1/4" DIRECT
INPUT. These inputs are selected in the middle position of the
dual-function phase
invert switch. We provide both transformer balanced XLR output as well
as a transformerless
"audiophile" 1/4" phone jack output. The Gain switch is actually a clever variable
feedback control that changes not only the gain but the
slew rate and flavour of the circuit. With it you can choose how laid
back and mellow or how
up-front and aggressive you want it to get.
See "Notes
on Variable Feedback" for more
info. Headroom is a
strong point in this circuit, +31dBu capable. This is 5 to 10 dB better
than almost all other pro gear.
The music passes through only our super-clean
pure Class A vacuum tube circuitry. There are obvious advantages
to our purist approach and foremost is the un-electronic final
sound that carries emotion into the digital realm.

COMPRESSOR
SECTION: This cool compressor design takes
our opto-isolator
approach of the Manley ELOP®
Limiter to the max. We adjusted the Ratio down to 3:1 to turn our ELOP
into a compressor and added ATTACK and RELEASE controls for more
versatility. What is clever is how the signal is compressed before it hits the tubes
with no detrimental effect on distortion or frequency response. This
way, it can prevent mic-pre
clipping and eliminate whole stages of electronics. This cuts the
typical path of mic to tape in
half! We also pioneered new thinking in the sidechain by using up to four different
time constants
simultaneously and controlling them with familiar simple attack,
release and threshold controls.
We call the approach "Parametric Compression". We
developed optimum settings or presets based our favorite Vactrols that
we use in our own fast
ELOP®
Limiter, the quick LA-2A's T-4 module, the slower LA-3A and then created
more complex special settings. This extended range and method of timing delivers fresh sounds
from powerhouse punching drums to super-solid bass
yet can also emulate the way good engineers delicately ride a fader
while recording. It is transparent and liquid-smooth on vocals, easy
to use and accurate. Also rare for an opto-based dynamic processor,
this compressor works great on mixes. Of course, you’ll be
needing two VOXBOXes linked in stereo...

EQ
SECTION: Lots of folks requested that we
include the Pultec Mid Frequency
Equalizer in the VOXBOX®, but they wanted MORE.... Now we’ve
extended it to 33 frequencies in 3 bands with 6 new frequencies
from 20 Hz to 150 Hz, and 6 more in the highs from 6.4 KHz
to 20 KHz. Ever notice that only EQs with real inductors have the
bottom end magic or that only Class A circuitry can keep the top
end sweet? This is for you. The EQ INPUT switch patches in the Line
Input, Preamp Output, or the INSERT return. This switch serves double-duty
acting as a bypass switch for the preamp and/or external
processors or for processing two different tracks.
|
|
DE-ESSER
& LIMITER SECTION: Designed by folks
with admittedly large gaps
between their two front teeth, (Hutch and EveAnna) the VOXBOX®
combo also
includes a de-esser & peak limiter based on our original ELOP®
Limiter design but with
an added passive LC network to handle the de-essing– four carefully
chosen notch frequencies from 3KHz to 12KHz. (That 3KHz setting
really tames those annoying frequencies!) The fifth position gives
you a limiter which
totally mimics the famous LA-2A. This means you can
both compress pre-EQ then limit here post-EQ. Another cool feature
is the ability to
insert this de-esser silently and smoothly as the music plays,
using it as needed.

The
METER is
a full size illuminated Sifam VU meter. A five-position switch shows three audio
levels: the line input, the preamp output and the final output.
It also shows compressor gain reduction and the de-esser/limiter
action. Other clever
innovations incorporated into the VOXBOX®
combo include warm-up muting
circuitry, extensive magnetic field containment, ‘smart -grounding’,
and silent switching.
The sum-total is more than the separate parts:
consider the reduced patching, the short path to tape and you having
this much immediate
control.
As
engineers, we choose what we use not based entirely
on features and functions– there is a sound, a texture we reach for
and the VOXBOX®
combo
puts the
‘Manley Sound’ together with ‘Your Sound’.

NOTE:
Operating mains voltage: Units are purpose built for original
destination country's mains voltage:
100V, 120V, or 220-240VAC as indicated on the serial number badge. Power
transformer must be replaced in order to change mains operating voltage.
120VAC units may NOT be rewired to put the primaries of the power transformer in
series for 220-240V operation or a large radiated field of hum will develop. If
changing locations/voltages, the power transformer must be replaced with the
dedicated one for the voltage at which it will operate.

I get replacements?
Older units before serial number MVB**1359 shipped
before 9/2003 use:
12V 1.2W FESTOON LAMPS; Manley's Part Number: VAR016C Order
these
spare bulbs using our parts order form.
Newest units after serial number MVB**1359 shipped after 9/2003 use yellow LED lighting
and those shouldn't burn out.
You can get in touch with Paul in
our service department and upgrade your older unit to yellow LED lighting
for $25 bucks.
2. Question: What's the "High Gain
Mod"?
The High Gain Mod for Serial Numbers MVB000 - MVB737
is available
for $150 cost and includes tube changes, resistor changes, re-cal and checkover plus
return shipping (within USA). This mod updates older Voxboxes to current version
(MVBX###)
for more gain: 40, 45, 50, 55, 60dB. Please contact Paul
in our service department to arrange this.
Or if you are as good a tech as we are, you may do it yourself. Step-by-step
instructions may be found here.
3. Question:
I have a VoxBox® which I use as my main
input into my PT system, recording not only vocals through it but most anything
else too. To achieve a stronger level from guitars you suggest running it
through an effects pedal before the VoxBox®.
Would running it through a Di first be better? And if so, would you
recommend active or passive or indeed your Dual Mono Di?
And Hutch's reply:
My comments were meant to address the low-ish gain of the VoxBox
Direct
Input and the possibility that some axes are quieter than average. In those
situations, one might need to boost the gain before it hits the VoxBox. Many
stomp boxes have gain or volume controls with more than enough range to
provide some seriously impressive levels.
Now a direct box is a completely different animal from a stomp box. The DI's
basic function is to turn an instrument signal into a mic level signal (or a
balanced line level signal). In the case of the former. A DI generally
reduces the voltage (-20dB) to be appropriate for a mic pre, which means you
would plug the DI into the Mic Input, and my comment wouldn't be relevant
because it was pointed at the Instrument Input. Might also be weird to go
thru adapters to drive a stomp box with a signal now dropped 20dB to raise
it back +20 to +40 dB again.
However, one could use most direct boxes to drive the mic input and have
plenty of gain in most cases. One wouldn't put a stomp box after a DI, but
if you like there is nothing to stop you putting it before the DI. In fact
one could "insert" the stomp box between the VoxBox Mic Pre and EQ
sections
though that signal may be a little hot, but workable. (or not)
And then there are some active Direct Boxes that convert an instrument
signal to line level, and the appropriate place to patch these is into the
VoxBox Line Input.
As to Active or Passive DI's - whatever works - whatever sounds right to
you! Basically they all sound a bit different, have strengths and weaknesses
and a few right ways to use them, plus many wrong ways.
The idea of the VoxBox Instrument Input was to allow most guys to not have
to require a Direct Box - just plug the axe into the front panel - bingo.
Several top session bass players do just that routinely. This doesn't rule
out that if you prefer, you can use a direct box that you love and patch it
into the Mic or Line Input, whichever is more appropriate for that box.
But the only point of all this is "Are the levels that YOU are getting hot
enough, OK or too hot?" If they are OK, no problem, if too hot, turn down
the gain, if not hot enough, then there are solutions maybe requiring a
stomp box or DI. And only YOU can really judge "better" and that only
requires listening and playing, rather than getting bogged in
technicalities, patching and electronics. Have fun, make music.....
