Routing and Auxiliaries

The routing matrix can send a channel to any of the 24 multitrack buses. The channel also provides 12 numbered auxiliaries and two cue sends for effects, foldback and other secondary mixes.

Multitrack bus routing​

The 12 routing switches address buses 1–12 normally and 13–24 when SHIFT is engaged.

  • BUS ROUTING switches assign the channel to the selected bus or buses.
  • SHIFT offsets the routing switches by 12.
  • FOLLOW PAN uses the channel pan position across odd/even bus pairs. Odd buses carry the left side and even buses the right side.
  • LF changes the routing source from the default Short Fader path to the Long Fader path.

For standard tracking, leave routing on SF so the Mic/Line record path feeds the multitrack buses. Use LF when routing a DAW/Tape return or other LF-path signal to the buses.

Auxiliary sends​

Each send-level control varies from off to 0 dB.

  • The numbered sends use LF by default.
  • The SF and PRE switches are shared by Aux send pairs: 1/2, 3/4 and 5/6.
  • SF changes both sends in the corresponding pair from the Long Fader path to the Short Fader path.
  • PRE takes both sends in that pair before the selected LF or SF fader rather than after it.
  • 7–8, 9–10 and 11–12 change the corresponding Aux 1/2, 3/4 and 5/6 controls to Aux 7/8, 9/10 and 11/12.

Pre-fader sends are useful for artist headphone/foldback mixes because changes to the channel fader do not change the send level. Post-fader sends are commonly used for effects where the effect level should follow the channel level.

Cue A and Cue B​

Cue A and Cue B operate as additional send buses and are intended particularly for artist foldback. Use the SF/PRE controls in the Cue section to select the required channel path and pre-/post-fader behaviour. The two Cue buses can also be treated as a stereo pair, with Cue A feeding the left side and Cue B the right side.
