ENHANCE 2
STEREOPHONIC ENHANCER
1
INTRODUCTION
Moving from mono to stereo sound: a logical
progression for any synthesist looking to expand
their sonic palette. Making use of two audio
channels, rather than just one, quite literally adds
another dimension to the capabilities of a
synthesiser.
Unfortunately, controlling stereo signals can be a
challenge within a modular system. This
realisation led to the development of Enhance 2:
a convenient yet high-fidelity tool for stereo
enhancement. It can be used to adjust balance,
width and spectral content, while also opening
up a world of mid/side processing; all under
voltage control and in just 8 HP.
The primary stereo parameters are balance
(moving the sound left or right) and width
(making it narrower or wider). The balance circuit
uses a true constant-power gain law, while the
width stage allows for seamless transitions from
pure mono to extra-wide stereo.
In addition, tone control is provided by a pair of
unique, wide-ranging
mid/side voltage
controlled tilt filters with selectable corner
frequency. These make ‘cleaning up’ a muddy-
sounding mix straightforward, but also provide
unique binaural effects when modulated.
Mid/side processing encodes the stereo signals
into one containing only the mono material
(mid), and another containing the differences
between both channels (side). Apart from the
internal tilt filters, mid/side outputs also enable
external signal processing such as compression
or reverberation. An integrated mid/side decoder
returns the results back to standard stereo. And
at all times, a LED bar phase meter ensures that
phase correlation can be easily maintained.
Stereo field modulation, mid/side equalisation
and beyond; Enhance 2 brings true analogue
stereo control to the Eurorack world.
