WZ 20S Application Notes
3
The WZ 20S is well suited to many high performance live, recording and installed sound
applications including multi source stereo mixing, multi output sub mixing, club systems,
small broadcast, production mixing... and more. The following notes present suggestions
for these applications. Of course, you may find different or better ways to suit the particular
requirements of your application.
Mixing Many Stereo Sources
There are many situations where you need to mix multiple stereo sources for
example keyboards, MIDI synthesisers, voice modules, sound cards, samplers,
outboard mic preamps, effects processors, CD, vinyl, DAT, MiniDisc, new media
players and recorders, stereo recorded tracks.
Dual stereo inputs
switch between them or mix them together as required. Inputs A and B have
independent gain control so that the balance can be set as required. You do not
need to reset the gain each time you switch the inputs. You also have the
convenience of selecting either the TRS jack or XLR connections as appropriate
rather than using cable adapters.
Split stereo inputs The two stereo inputs feeding each stereo channel may be
split so that input B feeds the channel and input A routes direct to the LR mix.
This provides independent control for up to 16 stereo sources. For example, tape
returns, MIDI voice modules and other pre-processed sources can route in this
way leaving the channels available for additional sources needing EQ and
processing.
External stereo inputs
stereo inputs to 18. You still have the four mono channels for microphone or line
level inputs. The EXT inputs are typically used to return the processed signal
from effects devices such as reverb, or to plug in a sub mixer.
Signal processing
equalisation. The six AUX sends provide plenty of outputs for effects, monitors,
mono or stereo sub mixes and special feeds. The effects can be returned to the
EXT or dual stereo channels.
combined into one stereo channel. The mono channels and main outputs provide
inserts for patching in additional signal processors such as compressors or
effects dedicated to individual sources.
Production and Recording
The number of inputs and processing power together with the sonic purity of
analogue sound make the WZ
program production.

or stereo effects returns. For multitrack recording you can connect up to 16 track
returns to the 8 stereo channels. You can use either mono or stereo channels to
connect to outboard mic preamps, increasingly common in the studio.
Outputs
independent recording devices. This is useful when recording translations and
voiceovers.
