Chapter 3: Mackie HUI Control Surface 29
Level Meters
The HUI has eight stereo, 12-segment LED lad-
ders for output level indication of individual
channels.
Meters match the peak reading features in
Pro Tools (clip hold and separate peak hold).
Press the F1 switch in the Function keys section
to clear clipped meters and last held peaks indi-
cations. Mono channels activate the left side of
the meter pair only.
The HUI level meters follow the Pro Tools set-
ting for Pre or Post Fader metering.
Multichannel Metering
Soloed Multichannel Track Display
You can temporarily display the multichannel
outputs of a given track during playback. While
pressing the OPTION button, press a track’s
SOLO switch to solo up to eight streams of a
track.
When a multichannel track is soloed in this
manner, the left side channel meters will dis-
play the levels of each component of the multi-
channel output. Multichannel tracks up to 7.1
in width (8 channels) can be temporarily soloed
and fully metered in this way.
The meters will revert to normal upon release of
the OPTION and SOLO buttons.
