Chapter 1 - Channel Types
1-10
Towards the bottom of the Outputs display, there are three buttons marked output (direct in Input channels), insert A and
insert B. Selecting one of these buttons assigns that send (or send and return) to the signal routing area above it: When either
insert is assigned, the ins A send or ins B send routing button appears in the left-hand column, and the ins A return or ins B
return routing button in the right-hand column; When the output (direct output in Input channels) is assigned, the outputs (direct
outs in Input channels) routing button appears in the left-hand column and the right-hand column is left blank. Pressing any of
these routing buttons opens a routing display.
An extra button labelled send+return is included above the ports list in the Insert Send Route display button. When this button
is activated, the send and return routing is linked for all signals within the INTERNAL port: If the Graphic 1 input is assigned to the
insert send, the Graphic 1 output is automatically assigned to that insert return. Similarly, if it is the return which is manually
assigned, the send automatically copies that send assignment. The send+return button is grey when inactive and brown when
active.
The mono > mono and mono > stereo buttons are used when routing a mono channel to internal fx units and Waves plug-ins
(where available). When mono > mono is selected, the channel signal is routed to left side of an fx unit, or to a mono Waves
rack input. When mono > stereo is selected, the channel is routed to both sides of the fx unit or Waves rack.
1.3.4 FX Presets .............................................................................
Each channel output or insert send can be sent to an internal FX Unit. Pressing the fx presets button at the bottom of the
Outputs display brings up the fx Presets display. The fx preset is applied to whichever channel output is active in the Outputs
display when the fx presets button is pressed: the main channel output (or direct output), insert send A or insert send B:
Note that column widths can be adjusted by dragging their borders within the title row. To return all col-
umns to their default widths, press RESET WIDTHS, in the top left-hand corner of the window.

1.4 Input Channel Specific Functions
1.4.1 Trim and Track ......................................................................
On Input channels which a mic or line input, there is a trim section at the bottom of the channel strip’s input area, consisting of a
smaller pot marked trim and a track on/off button. The trim pot digitally trims the level of the input signal, and the level adjustment
is displayed to the right of the pot in dB. If track is switched on, the trim level automatically compensates for any adjustments
made to the analogue input level: If the analogue input level is increased, the trim level will decrease in order to keep the signal
level coming through the channel at the same level. This function is particularly useful when the analogue level is being controlled
from another console, such as when this console is running monitor mixes and another console is running Front of House. Control
of the trim pot and track on/off button can be assigned to the encoder and button above/below the channel using the assign
scrollers to the left of the encoders or the quick select buttons.
Relative Gain-Tracking - Snapshot Recalls Total Gain
“Relative Gain-Tracking” is implemented as a “Snapshot Recalls Total Gain” option at the bottom of the Snapshot Global Scope
panel. When a snapshot recalls an input channel trim, it compares the snapshot’s stored analogue gain against the current gain
on the channel’s input socket. If there’s a difference it offsets the value recalled by the trim. This only happens when the
socket’s rack is in Receive Only, or the analog gain is not in Recall Scope.
