Manley VOXBOX - MVB 1996 - 2/2000 and MVBX 6/2000 - 4/2003 - Manual (Page 3)

INTRODUCTION

THANK YOU!...
for choosing the Manley VOXBOX. This unit is the result of our customers asking us to make a vocal
oriented combination from some favorite Manley designs. We combined the Manley Mic Preamplifier,
Electro-Optical Limiter, and Mid Pultec and then went further. Uniquely, we put a compressor before a
minimalist mic preamplifier. This can substantially reduce distortion while having no more sonic imprint
on the signal than the mic pre by itself because the compressor is just a passive light dependent clamping
resistor. For those who want the shortest path to tape, but use compressors, this has to be the ideal solution.
We added attack and release controls to the compressor with some "very special" settings such as one
that simulates a LA-2A, another "tuned" for drums and a setting that works like a great engineer "riding"
a fader. Then we extended the PULTEC MEQ down to 20 Hz and up to 20 kHz so its not just a mid EQ
anymore. To this we added a new de-esser circuit and gave it a "Limiter" setting. This final de-esser /
limiter is completely independent of the compressor and is post EQ.
We wanted the VOXBOX to be "Manley quality" and the first and only "analog combo" (other than
consoles) to make a serious entry into the major studios. We provided our style of balanced inputs and
outputs and used fewer but better parts. It only required five Manley audio transformers, six multi-tapped
inductors, two expensive Multi-Caps, four mil-spec JAN tubes, four Vactol opto-isolators, five regulated
power supplies, six Bournes conductive plastic pots & seven Grayhill gold contact rotary switches. A few
of these items are likely to cost more than other manufacturer's total parts. With all these serious
transformers we even provided ways to go transformerless,the minimalist and purist way to go. We went
to great lengths to eliminate typical clicks and pops from switches. The compressor and limiter can be
switched in while recording and the change happens smoothly. We added auto-mute circuitry to eliminate
the turn-on & turn-off thump and regulated all the power supplies. In fact many of these developments
are being incorporated into our next versions of our other pro products.
While we were designing the VOXBOX we couldn't help but notice how well it would work on other
instruments besides voice. There were some great settings for drums (unusual), bass, guitar and keys.
So don't just use it for voice - you can use it everyday and in any situation regardless of how well equipped
the studio may be. The name "VOXBOX" represents only the beginning and the most obvious application.
Please take a few moments to read through this manual carefully as it contains information essential to
proper operation of this unit and we scattered little hints all over. Thank you again, and please enjoy !
GENERAL NOTES
LOCATION & VENTILATION
The Manley VOXBOX must be installed in a stable location with ample ventilation. It is recommended,
if this unit is rack mounted, that you allow enough clearance on the top and bottom of the unit such that
a constant flow of air can move through the ventilation holes.
WATER & MOISTURE
As with any electrical equipment, this equipment should not be used near water or moisture.
SERVICING
The user should not attempt to service this unit beyond that described in the owner's manual.
Refer all servicing to your dealer or Manley Laboratories.
