8.78. NCL -- Set Noise Cancellation Attenuation

This command sets or queries the attenuation level of the Noise Cancellation algorithm on input
channel 1 . For example, if NCL is set to 10, then the Noise Cancellation for that channel will cancel
10 dB of noise. Higher numbers mean more cancellation will be applied, but may result in slight
artifacts depending on the characteristics of the noise. Typical settings are 10 dB for normal
cancellation and 6 dB for light cancellation.
This command is a channel integer command. See
on this type of command. The minimum and maximum values for this command are 0 and 20,
respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.

8.79. NVINIT -- Reinitialize Non-Volatile Memory

This command reinitializes (or formats) all non-volatile memory settings. This will effectively erase
settings for global settings, user presets, macros, labels, and logic I/O configurations. This will
basically reset the unit to a "fresh-out-of-the-box" state.
Q01NC*0
Q01NC*x, where x is 0 or 1 depending on
the current state of NC for each of the
corresponding input.
Q01NC*x, where x is 0 or 1 depending on
the current state of NC for each of the
corresponding input.
Section 6.3 and Section 6.2
Status Message
Q01NCL13
Q01NCL1x , where x is a number
between 0 and 20, depending on the
current setting of the NC attenuation
level on input channel 1 .
Q01NCL*è
Q01NCL*x, where x is between ä and ÿ,
depending on the current setting of the
NC attenuation level for input 1.
