PWM Frequency:
The output PWM frequency is set through this parameter, with “XX” being the frequency in
kHz. The default value is “01”, corresponding to 1kHz. Options range from “00” = 500Hz to
“30” = 30kHz.
The output PWM frequency can be adjusted to avoid flicker in different settings. It can be left at
1kHz for most applications. For on-camera use, settings around 5kHz are typically sufficient to
eliminate flicker. Very high frequency settings (over 10kHz) should be used only if necessary.
Very high frequency signals can be distorted by long cable runs and/or environments will a lot of
electrical signals.
Output Dimming Curve:
The “gamma” value of the dimming curve is set with this parameter. This changes the rate at
which the brightness changes at different DMX values. It can be used to make dimming less
sensitive at the high or low end for greater precision in that brightness range. Default value is 1.5
and can be adjusted from 0.1-9.9. Values less than 1 give greater dimming precision at high
brightness and values greater than 1 increase precision at low brightness. Human vision is more
sensitive at low light levels, so values greater than 1 are most common.
