MAC Aura XIP User Manual
Pan and tilt
The MAC Aura XIP offers 540° of pan and 220° of tilt.
See the pan/tilt orientation reference drawings at the end of this user manual for a guide to the direction of
pan and tilt movement.
16-bit pan and tilt control are available. In each case, the second (LSB) DMX channel adjusts the position
set on the first (MSB) channel.
It is possible to set limits for the pan and tilt range (see details on page 18).
LED PWM frequency control
The PWM frequency of the MAC Aura XIP’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.
You can adjust the PWM frequency via DMX using channel 20. Note that the new PWM adjustment value is
not stored permanently in the fixture, so you have to keep the channel 20 at the chosen value in order to
keep the LED PWM frequency at the corresponding custom value.
You can adjust PWM frequency as follows:
High-speed PWM Frequency Mode drives the LEDs at 24 000 Hz. This frequency greatly reduces electronic
switching noise but it gives slightly faster cut-off at the low end of the dimming range.
The default PWM frequency is 3000 Hz.
Pre-programmed FX
The MAC Aura XIP offers a range of pre-programmed effect macros that we simply call FX. See a full
description under “FX: pre-programmed effects” on page 36
FX give instant access to complex dynamic effects with no need for time-consuming programming at the
controller.
