MAC Ultra Wash User Guide
LED PWM frequency control
The PWM frequency of the MAC Ultra’s LEDs has been chosen carefully to avoid flickering on camera. In
some rare situations – for example when using cameras with non-standard settings – it may be necessary to
adjust the LED PWM frequency manually.
From firmware version 1.2.0 (due for release mid-2021), you can do this via DMX by sending value 255 on
either the FX1 Selection or the FX2 Selection channel. Once activated, the corresponding FX Speed and
Direction channel will control the LED PWM frequency. Note that this change is not stored permanently in
the fixture, so you have to keep the FX Selection and FX Speed/Direction channels at the chosen values in
order to keep the LED PWM frequency at the corresponding custom value.
The default PWM frequency is 3000 Hz.
Pre-programmed FX
From firmware version 1.2.0 (due for release mid-2021), the MAC Ultra Wash offers a range of
pre-programmed effect macros that we simply call FX.
FX give instant access to complex dynamic effects with no need for time-consuming programming at the
controller.
