F01NC*2

Toggle NC state on all microphone input

channels (1-8) .

F01NC*abcdefgh , where the letters (a, b, etc.) are each

0 or 1 depending on the current state of NC for each of

the corresponding input.

F01NC*?

Query NC state on all microphone input

channels (1-8) .

F01NC*abcdefgh , where the letters (a, b, etc.) are each

0 or 1 depending on the current state of NC for each of

the corresponding input.

8.99. NCL -- Set Noise Cancellation Attenuation

This command sets or queries the attenuation level of the Noise Cancellation algorithm on input channels 1-8 .

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

Section 6.3 and Section 6.2 for more information 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.

Example Description Status Message

F01NCL13

Set NC attenuation level on input

channel 1 to 3 dB.

F01NCL13

F01NCL1?

Query the NC attenuation level on

input channel 1 .

F01NCL1x , where x is a number between 0 and 20,

depending on the current setting of the NC attenuation

level on input channel 1 .

F01NCL*6

Set NC attenuation level on all

microphone input channels (1-8)

to 6 dB.

F01NCL*èèèèèèèè

F01NCL*ääääìììì

Set NC attenuation level on input

channels 1-4 to 0 dB and NC

attenuation level on input

channels 5-8 to 9 dB.

F01NCL*ääääìììì

F01NCL*?

Query NC attenuation level on all

microphone input channels (1-8) .

F01NCL*abcdefgh, where a-h are each between ä

and ÿ, depending on the current setting of the NC

attenuation level for each of the eight input channels.

8.100. 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.

When this command is issued, it writes to non-volatile memory in order to format the contents back to the

factory default state. The writing process results in a short delay. After the non-volatile memory has been

reformatted, the Vortex will perform a software reset, which is equivalent to a power cycle.
