Adjust The Pulse Width Modulation (Pwm); Test The Emitters - ETC Desire Fresnel User Manual

Adjust the Pulse Width Modulation (PWM)

If you are encountering flickering in recorded video, you can adjust the Pulse Width Modulation
(PWM) to correct it.
1. Press the Menu button (
then press the Intensity encoder to select it.
2. In the Local Settings screen, turn the Intensity encoder to select the PWM parameter, and
then press the Intensity encoder to select between the two options:
High: The 25 kHz setting prevents flickering when recording video. This is the default
•
setting.
Low: The 5 kHz setting provides greater control of low-end dimming.
•
3. Press the Menu button (
screen when you are done.

Test the Emitters

As part of troubleshooting any issues with a fixture, you can test the emitters, either as a group
or individually by color.
1. Press the Menu button (
menu: Diagnostics > Test.
2. In the Test screen, use the blue encoder to select the emitters to test, and the green
encoder to set the level for the emitters:
Press the blue encoder to select all emitter colors, or turn the encoder to select an
•
individual emitter color. (De = Deep red, Re = Red, etc.)
Press the green encoder to toggle between off and full (FL) for the selected emitters,
•
or turn the encoder to set a specific level (0%–100%).
3. If necessary, use the Intensity encoder to set the intensity level for the emitter test.
4. Press the Menu button (
screen when you are done.
Note:
the Main Menu screen when you are done, the Test screen will time out based on the
Timeout setting (see
Timeout setting to Never and do not exit the Test screen, the fixture will remain in test
mode (overriding any other instructions to the fixture) until you return to the Test screen
and exit it.
