Surface Metering

Main LED meter

The 12 segment LED metering on the surface of the Qu to the right of the touchscreen displays level metering for the PAFL bus, so will always show metering for what is being sent to the headphone output.

By default, with no PAFL keys active, this displays the Main LR Mix level.

ⓘ The PAFL LED indicator below the 12 segment LED illuminates when a PAFL routing key or button is active anywhere in the mixer.

 

Channel Metering

Each channel strip includes a Chromatic Channel Meter to show level, and a Peak LED to indicate that the signal is peaking somewhere in the signal path.

 

Peak Metering

As long as a peaking channel has been assigned to a channel strip, there is always visibility of any peaking on the Qu surface to allow potentially destructive peaking anywhere within a channel to be found as follows:

  • If a channel is peaking on a channel strip on an inactive layer, the Layer selection key will illuminate red.
  • With the layer selected, the red peak (Pk) LED on each channel strip uses multi-point sensing to display peaking anywhere in that channel’s processing path.
  • With the channel selected, the red peak (Pk) LED’s next to dedicated processing controls (Preamp, PEQ, GEQ, Compressor) will illuminate when signal reaches -3dBFS at the meter directly following that processing ‘block’. 0dBFS is absolute maximum, so the Pk LED indicates the signal is close to digital clipping at that point.

 

GEQ ‘Fader Flip’

When in GEQ Fader Flip mode, if the RTA is assigned to the channel (e.g. visible in the PROCESSING screen), the Chromatic Channel Meters will display the level of each frequency band above the fader that controls it. The most prominent frequency is also displayed using the Pk LED’s.

If the RTA is being used on a different channel to the one selected, by the Qu-MixPad app for example, the Chromatic Channel Meters and Pk LED’s will not illuminate.

 

Meters Screen

|| METERS | Overview

Throughout the meters screens:

  • The main channel level meters display signal from -40dB to +10dB.
  • Gain reduction meters on the right of each channel meter show level reduction from 0dB to -30dB, these are red/bright red when the compressor is switched in and dark/light grey when it is switched out.
  • Gate active indicators are red/bright red when the gate is switched in and dark/light grey when the gate is switched out.

 

Overview

The Meters overview displays all Input, FX Send and Return and Mix meters, along with the meters for the currently selected fader Layer on a single screen.

  • Touch any tab at the top of the screen to view larger meters for each channel type.
  • Touch any section of meters to jump to the relevant tab.
  • Use the surface Layer keys to select which layer is currently selected and displayed.

 

Inputs

  • Touch the Input Meter Source to choose the metering point for all Input channels. Note this also applies to the Chromatic Channel Metering on the surface.
  • The top section displays larger meters with channel name and colour.
  • The lower section displays all input meters and can be used for navigation.
  • Touch and drag left and right on the top or bottom sections to view all input meters.

 

FX

Displays all FX Send and FX Return channel meters.

 

Mixes

Displays all Mix channel meters.

  • Touch the Mix Meter Source to choose the metering point for all Mix channels. Note this also applies to the Chromatic Channel Metering on the surface.

 

USB/SD

USB input meters show signal from either USB-C or Qu Drive playback, with Qu Drive playback having priority.

USB output meters show the output signal from channels that have been patched to USB output sockets in the I/O screen.

 

Layers

Displays all the meters for all fader strips of the currently selected fader strip layer.

  • Use the surface Layer keys to select which layer is currently selected and displayed.

Chromatic Channel Metering

|| METERS | Channel Meters

The Chromatic Channel Metering displays the information of a high-resolution meter in the space of a single LED on each channel strip. It can depict a much greater range of levels than a traditional meter and behaviour is customisable in the Channel Meters tab.

  • Touch an Audio Level value and adjust using the touchscreen rotary.
  • Touch a colour for an Audio Signal State and use the touchscreen rotary to adjust the colour/s for this level range.
  • Touch the Intensity value to choose the behaviour of the meters.

Fixed - Meter switches instantly between states.

Variable 1 - Meter changes close to the endpoints of its range.

Variable 2 - Meter changes across its whole range.

  • Touch the Restore to Defaults button to restore settings:

ⓘ The Chromatic Channel Meter source matches the meter source point selected for Input and Mix Meters.

ⓘ Audio Level values are bound by the level setting of states above and below.
