Input Calibration allows GENOME to accurately match the signal level expected by compatible amplifier and pedal models. When configured correctly, it ensures consistent behavior between different model formats and technologies, helping them respond as intended to your instrument's input signal.
For TSM-Ai Amplifiers and Drive Pedals, calibration is applied automatically.
For NAM and Ampnet models, Input Calibration and Output Calibration must be enabled in the corresponding Codex or Paradex instance settings.
The Input Calibration setting can be found in:
The default value is set to +10 dBu.
This value can be modified at any time. You may also define a new default value, which will be applied automatically to future GENOME instances.
Input Calibration is an instance-level GENOME setting and is not stored within Rig Presets.
The Input Calibration setting should match the maximum input level of the audio interface input you are using when its gain is set to 0 dB.
This specification is typically available in your audio interface documentation and may be listed as:
*This naming convention usually means Minimum Gain is a negative value (padded input), and not 0.
Depending on the manufacturer, this value may be expressed in dBu.
This value is usually between 0 and +20 dBu.
If you cannot locate this information, or if the published specification is unclear, we recommend contacting your audio interface manufacturer directly for confirmation.
Please note that maximum input level specifications are theoretical values and can vary depending on how the manufacturer measures and reports them. As such, they may not always correspond exactly to the effective operating level of the interface.
If you are unable to locate the maximum input level for your audio interface, or simply want a good starting point, the table below provides recommended Input Calibration Value values for a number of commonly used interfaces.

The values shown above are intended as guidance only and should not be considered definitive. They are derived from publicly available manufacturer specifications together with measurements contributed by members of the Two notes online community. Actual input sensitivity may vary depending on hardware revision, firmware, driver implementation, input mode, gain structure and the manufacturer's measurement methodology. Where available, we always recommend using your audio interface manufacturer's published specifications as the primary reference.
Input Calibration is primarily intended for use with compatible amplifier, drive pedal and studio outboard gear models.
If no compatible component is present in the signal chain, the Input Calibration control behaves as a simple input gain adjustment.
For this reason, if GENOME is being used only for mixing or effects processing (such as EQ, modulation, delay, reverb, or cabinet simulation) within a larger calibrated plugin chain, the Input Calibration setting should generally be left at its default value of +10 dBu.
No.
GENOME will continue to function normally even if the Input Calibration value is not configured. Most users can achieve excellent results without adjusting this setting.
However, setting the correct calibration value allows compatible AI-based amplifier and pedal models to operate under the conditions they were designed and captured for, resulting in the most accurate and consistent behavior across supported model formats.
