Using UltraStudio 4K Mini's
Front Control Panel
On UltraStudio 4K Mini, most of the settings that can be changed in the Desktop Video Setup
utility are also available via the LCD menu on the front panel. To navigate through the settings,
press the 'menu' button to open the menu, then scroll through the options using the settings
knob. To enter submenus and confirm a setting, press the 'set' button.
To exit the menu, keep pressing the 'menu' button to step back through the menus and return
to the home screen.
TIP You can also navigate directly to the video or audio settings by pressing the
'video' or 'audio' buttons. This lets you go directly to the relevant settings without
scrolling through the settings list, which can save time.

Audio Settings
UltraStudio 4K Mini also has additional audio settings in the LCD menu. These settings let you
change the type of audio meters displayed on the LCD during capture and playback. The two
audio meter types are VU and PPM.
VU
The VU meter, or 'volume units' meter, averages out short peaks and troughs in your audio
signal. If you are using VU metering, adjust the output levels of your source so that the meter
peaks at the 0db indicator on the audio meter. This maximizes the signal to noise ratio and
ensures your audio is at the highest quality. If your audio peaks beyond the 0dB indicator there
is a high risk of sound distortion. If you are using the analog audio inputs of the UltraStudio 4K
Mini, the input levels can be adjusted in the LCD menu or setup utility.
PPM
PPM meters, or 'peak programme meters', display a 'peak hold' feature that momentarily holds
the signal peaks with a slow fall back so you can easily see the audio level at which your audio
is peaking.
Both VU and PPM meters can be set to use reference levels of -18dB or -20dB so you can
monitor your audio to suit different international broadcasting standards.
SD Card Slot
UltraStudio 4K Mini's front panel also features an SD card slot that reads and writes files when
the unit is connected to a Mac or Windows computer. This slot can be used just like a typical
SD card reader or writer and is detected by your computer as another drive. This means you
can quickly import clips from your camera's SD card or set Media Express to capture a clip to
portable media.
