1. What is bx_digital V2?
bx_digital
V2
is
a
latency-free
De-Esser
that
works
in
several
sophisticated M/S modes for mastering and microphone recordings.
It is based upon the "modern classic" bx_digital V1 and the analog bx1 EQ. We
developed this hi-end analogue EQ 2006/2007 and we offered an emulation of
this EQ ever since.
The hardware bx1 is our „MODUS EQ", an analogue high class equalizer that runs
in four different modes, giving you up to three channels of extremely musical filters:
•
a conventional L(eft) and R(ight) stereo mode for any stereo/dual mono
applications.
•
a stereo mode with a built-in M/S-matrix, mainly used for stereo mastering
purposes.
•
a 3-channel mode (one stereo PLUS one mono channel) for surround
mastering & recording studios purposes.
•
an M/S-Recording-mode that will use two individual microphone-signals
(M&S-signals) fed into the bx1 to create a highly mono compatible stereo
signal, mainly used for orchestral recordings, choirs or for recording accoustic
instruments in general.
The hardware bx2 is an „Image Shifter" and De-Esser that can work in M/S
mode as well and therefore is the perfect extension to our bx1 when it comes to
mastering stereo signals. It also includes a „Mono-Maker" that allows you to mono
the bass frequencies of your mix from 20 Hz up to 22 kHz to make sure your
bass-section is „tight" and compatible for vinyl-pressings.
The bx_digital V1 was an exact emulation of both units´ features, our state-of-the-
art equalizer bx1 and its expansion unit bx2, with only one mode of the hardware
(the 3-channels-mode) not working (for audio host standard reasons). Together
these two units are the perfect choice if you are looking for an extremely musical
and tasty way of eq-ing and de-essing stereo signals (mixes), most likely in a
11-band
stereo
EQ
and
stereo
modes,
among
them
mastering process, or if you are into mixing and sound-design as well as recording
with M/S-microphone-technique.

bx_digital V2 now offers additional features that neither the original bx1 analog EQ
nor the v1 plug-in offered.

2. What is M/S technology?
Most engineers who are recording music know about the M/S microphone
technique (two different microphones for stereo recordings - an OMNI or CARDIOID
microphone for the M (mid) signal and a "FIGURE-OF-8 microphone" for the S (side)
signal).
Recording a signal with M/S microphone technique means to create a stereo
(L/R) signal by mixing the M and the S signals together in a special way that will
result in a very mono-compatible stereo signal. To record in M/S you have to feed
the M-signal to the Left and Right channel of your mix and the S-Signal will be fed
phase-correct to the Left channel and phase-reversed to the Right channel. This
means you will have to split the S-signal and use a total of 3 channels for only 2
microphones that will be mixed together to create a conventional stereo-signal.
Quite confusing?
Well, bx_digital V2 does all that work for you, just feed it with the separate M- and
S- microphone signals and switch it to M/S Recording...
For additional details about this technique you may have a look into any decent
audio book. Please do so if you want to learn more about this method to create
very mono-compatible stereo-signals, e.g. when recording classical music, drums,
choirs or acoustic instruments in general.
