button is selected and either or both of the routing buttons are selected.
LINE HOLD Selection
The LINE HOLD button works in conjunction with the fader and is used to control channel
remotes and routing. The button shows various states. When unlit the channel is o.
Flashing red indicates that the channel has been selected to LINE HOLD but remains
unrouted i.e. neither PGM or AUD is selected. Steady red indicates that the channel is
holding the telephone line and “armed”, ready for the fader to be raised. Raising the fader
changes the illumination to green indicating that the channel is live. Alternatively, with the
button unlit the fader may be raised and the channel can be operated simply by selecting
LINE HOLD button (Note though that this will cause dial tone and the dialling of the call to
be heard on-air). The illumination in this case toggles between unlit (channel o) and green
(channel on). Remotes are triggered when the LINE HOLD button is on.
Scribble Pad
A scribble pad is provided at the bottom for user labelling of the channel function.
