•
Control Input Option: This dropdown menu assigns the control function of the external
switch connected to the CONTROL INPUT.
•
External Loop Safe Mode: When using the EQ2 External Loop routing options, we suggest
enabling this hardware option to prevent feedback in your external loop when the EQ2 is
bypassed.
•
Power Up State: Selects between engaging or bypassing the effect upon the initial power up
of the pedal.
•
Default Routing Option: Sets the default I/O signal routing mode. Descriptions of the
available routing modes are available in the
manual.
•
Tuner Reference Pitch: The typical reference pitch for tuning stringed instruments is
A=440Hz, but for alternate use, the reference pitch can be set from 430Hz to 450Hz. Some
musicians, like Jimi Hendrix, have preferred A=432Hz, suggesting it is more pleasing to the
human ear.
•
Pedal Input & Control Input Calibration (Accessible via the Show Expression Pedal
Calibration dropdown controls): In some cases, it might be necessary to adjust the
calibration range of an expression pedal to get the desired pedal response when using
expression control either through the Neuro Hub, a direct connection to the Source Audio
Dual Expression Pedal, or a 3
pedal and press the "Calibrate" button. Then rock the pedal back and forth to set the
minimum value and the range. When complete, press the "Stop And Set" button to retain
the new calibration values. Or press "Reset" to return to the default values.
