SA248 Spectrum Intelligent Filter User Guide 22
Default Input: Selects the default configuration of the Input jacks. There are four different
options: Auto Detect (Default), Single Input 1, Dual Input 1 & 2, External Loop (Pre-
Processing). Go to the Routing and Options section for details on all of the routing choices.
Quick Bank Switch Using Footswitch (2 Seconds): By default you can only use the footswitch
to alternate between Preset Bank 1 (Green LED) and Preset Bank 2 (Red LED) from the
disengaged state. Checking this box allows you to alternate Preset Banks quicker AND from
the engaged state.
USB MIDI Skip Power Check: The Spectrum can receive MIDI PC messages via the pedal’s
USB port. It requires MIDI DAW software or a MIDI host device with USB. The Spectrum
should respond to most devices, but some don’t generate enough power for the Spectrum to
recognize them as a MIDI host (the MIDI Baby and qCONNECT from Disaster Area Designs are
two examples). If your Spectrum is not responding to your MIDI host device, try checking this
box.
Show Expression Pedal Calibration: If necessary, open this control set to calibrate external
expression pedals.
Preset Editor
Click the Sound Editor (wrench) icon in the Connections section to open the Spectrum’s Sound Editor
in the center tab. This is where all of the sound editing work takes place. The Sound Editor is broken
into several sub-sections, each containing a unique variety of virtual knobs and dropdown menus.
The following is a brief explanation of each Sound Editor sub-section.
Master Controls
The controls that populate the Master Controls section apply to all Voices in the Spectrum Editor.
Input 1 Gain 1 & Input 2 Gain: Because the Spectrum’s envelope followers respond
differently depending on the level of signal going into the pedal and because the output
levels of different instruments vary so greatly, it can be helpful to adjust the level of signal
going into the effects processor. The two Input Gain controls make it possible to adjust the
level from Inputs 1 & 2 independently.
Master Depth: A master control for the modulation depth of Filter 1 and Filter 2. When
running both filters simultaneously the Master Depth control adjust the depth of both filter
to scale with their individual settings.
Mod Source (ENV / LFO): Adjusts the mixture of the modulation source. The modulation
source refers to the mechanism that moves (a.k.a. “modulates”) the filters. The Spectrum has
two types of filter modulation: the envelope follower (ENV) moves the filter based on the
