INFO submenu
1. Temperature: Titan™ reads the temperature of LED1 and LED2 PCBs, and also the driver PCB. It also reads the
RPM of the Fans. This is read-only data. Please note that Titan™ X1 does not have a ‘Right LED’ board, but will
continue to display the RPM of the right hand Fan. RE: Fan RPM: the current fan RPM is displayed here. This will be
based on the operating temperature of Titan™, and the selected ‘thermal management’ mode (see SYS/settings).
2. Volts: Titan™ accurately measures the incoming voltage and this is displayed here. Titan™ also calculates the
average voltage during the last three flash events, so you can see if your power supply is coping well with the extra
power required for flash. Finally the right hand knob controls fixture brightness on this page, and you can adjust
this and see what effect this has on the power source voltage. Please note that we recommend that you only use
Rotolight power adapters or battery adapters. The incoming voltage must not exceed 24-25volts DC or damage
may occur to Titan™
FDIM (True Aperture Dimming™) submenu
The fifth submenu item, is a special function called FDIM (i.e. F-Stop Dimming/True Aperture Dimming™). This
feature is an exposure calculator. It shows the brightness setting as an accurately calculated aperture (f-stop) for
your subject at a given distance, using your camera ISO and shutter. It also provides a nice way to accurately adjust
your key light to match your camera settings, rather than the other way round, which can be very useful.
Select the menu item ‘FDIM’ . Rotating the left knob adjusts the ‘Exposure’ duration setting (set this to match your
camera). The centre knob adjust the ISO setting (set this to match your camera). If you press and turn the centre
knob, you can input the distance of the Titan™ from you subject.. Finally, if you rotate the right knob, it will adjust
the brightness of the Titan™, whilst displaying the correct Aperture (f-stop) setting for your camera.
Please note the ‘True Aperture Dimming™’ algorithm calculates the f-stop based on the Titan™’s brightness
setting, your camera’s ISO and shutter speed, the distance to the subject and compensates for the skin contrast of
the subject.
You can also decide to work in reverse, i.e. you creatively choose an Exposure duration, ISO, AND aperture (i.e. f3.0),
so now you can match your light to your camera exposure settings, this way all the photos from your shoot will
have the same grain structure, depth of field, etc. This is a novel and very useful way of working creatively, and can
also save a lot of time, whilst delivering consistent results from a shoot.
SYS User Presets
The user presets in the SYS menu are numbered from 11 through to 20. You can store your custom system settings
by holding one of the preset buttons, you can recall a system preset by tapping one of the preset buttons, and if a
preset is highlighted you can delete it by pressing the ‘BACK’ button. On future updates you will be able to ‘load/
save’ presets and banks to/from the USB stick, by double tapping the preset or bank button (feature due 2021)
