Stereo Inputs and Subgroups

Stereo Inputs​

The four Stereo Inputs provide additional return paths for effects, samplers or other line-level sources without using a full main channel.

Each Stereo Input provides:

  • Record-bus routing switches with SHIFT for buses 9–16
  • F/B A and F/B B sends to the Foldback system
  • Input TRIM of +/-20 dB
  • Rotary FADER
  • MIX assignment to the stereo bus
  • SOLO using the currently selected solo mode
  • CUT

Because the Stereo Inputs can be routed to the record buses as well as the stereo Mix, returned effects may be recorded if required.

Subgroups and Line Inputs 17–24​

Buses 1–8 also feed eight subgroup paths in parallel. Each subgroup provides pan, Mix assignment, Solo, Cut, a fader and an insert point.

  • PAN positions the subgroup across the stereo Mix bus.
  • MIX assigns the subgroup to the stereo Mix bus.
  • SOLO auditions the subgroup using the selected solo mode.
  • CUT mutes the subgroup.

The eight subgroup faders sit in the centre section. Each provides a normal 0 dB operating point and up to +10 dB of gain.

The subgroup insert returns also function as Line Inputs 17–24. When a return is being used as a subgroup insert return, it is not simultaneously available as the corresponding additional line input.
