Specifications
Anti-Feedback Filter:
Cut: -14 dB
Bandwidth: 0.25 octave (-3dB from baseline gain)
Default Frequency: 100Hz (Without running “Measure”
calibration)
Compressor
C1-C9: Chord/strumming style
Sustained with smooth attack
L1-L9: Lead style
Percussive attack characteristic
Compression threshold: -22dBu
Compression attenuation at -10dBu:
1dB - 9dB corresponding to the
number in the selected compression
setting.
Example: C7 or L7 would produce a maximum
compression of 7dB.
Noise Gate: On when compression is selected.
Gate Threshold: -46dBu
Normalized Compressor Drive Gain:
To minimize shift in operating level,
mid level gain increases proportional
to each of the compression settings
