Routing & Options
The Spectrum's stereo inputs and outputs offer dramatic stereo effects and numerous complex signal
routing options, including "side chain" and the insertion of external pedals to the signal path. Side
chain is particularly useful with envelope filters, because a dry signal is sent to the envelope detector,
while the wet signal is sent to the filter section. A useful template for side chain routing can be
found as a factory preset in the Neuro preset library. Many other stereo routing options can be
accomplished with each Voice's Processor Pan parameter combined with the final Destination
dropdown in the MIX 1 & 2 blocks. (See the Processor Pan section for details on stereo routing)
Input Routing Option: Selects the configuration of the Input jacks per preset. There are four
•
different options:
Auto Detect (Default): This is the default setting – it detects which input jacks are
o
currently being used and configures the routing accordingly.
Single Input 1: Use this setting if you have a single instrument cable plugged into
o
Input 1.
Dual Input 1 & 2: Use this setting if you have instrument cables plugged into both
o
Inputs 1 & 2.
External Loop (Pre-Processing): It is possible to manually set up most all stereo Input
o
and Output routing using a combination of the Processor Pan parameter in each of
the Voice blocks and the Destination dropdown menu in the Mix blocks – this
includes effects loops either between Voices or at the end of the signal path. The one
routing option that can't be set up manually is the an external effects loop that
places the external effect in front of the Spectrums's Voice processor. Choose this
option if you wish to create a pre-Voice external effects loop. See the diagram below
to get a better understanding of the routing.
