ReQ·131 Instruction Manual
v1.2
D) Using the ReQ·131 to process MID and SIDE signals in series
In setup (D), this approach uses 2 ReQ·131’s in series (one after the other), as an insert chain. The
difference between this setup and prior setups is that the mode is set for each ReQ·131 to process the
specific Mid / Side signals, rather than effect the full signal coming out of the sampler / synth module.
ReQ·131 #1 has been set to ‘MID 12dB’ mode, meaning that whatever we change on the front panel*
of this particular instance will affect ONLY the MID content of the audio signal. What in turn this will do
is attenuate frequencies found ‘centrally’ to the mix (also known as ‘phantom centre’), so central sounds
can be boosted without affecting hard panned or very wide stereo signals.
Continuing through the chain, ReQ·131 #2 has been set to ‘SIDE 12dB’ mode, meaning whatever we
change on the front panel* of this instance will affect only the SIDE content of the audio. This would
allow us to attenuate frequencies that are not central to the mix (ie hard panned signals, phaser / chorus
/ unison / reverb effects for example). NOTE: some effects mentioned may also include MID signal
information as well as SIDE signal information.
To determine what you are equalising in each mode, you can do the following: ‘BYPASS’ one of the
ReQ·131’s and activate the HEAR EQ button, to hear ONLY the signal of the MID/SIDE matrix alone
and out of context, so you can really focus on that particular signal type. Turn off HEAR EQ to hear your
equalised MID/SIDE signal in context with the non-processed part of the MID/SIDE matrix signal.
Additionally, you can use the DRY/WET knob in all setups explained, to mix and compare between your
new EQ adjustment and your original signal, which gives you the opportunity to process in parallel
For more information on selecting the signal mode and what MID and SIDE information is, please refer
to the sections ‘Selecting the Signal Path and dB ranges’ on page 14, and ‘HEAR EQ mode and how it
works’ on page 15.
* all except the GAIN control, which affects the final output level of the RE, and controls the dry level &
wet level at the same time.
