Rate Playback and Stack Programming
Overview
A Rate Playback is a cue replay device, which enables the operator to
control the rat of a cross fade between two cues. The cues are pre-
programmed, entered in order into a cue list, or stack and replayed using
the digital fader and associated control buttons. The replay can be manual,
semi automatic or fully automatic depending upon the exact requirements.
Creating a new Stack
This procedure assumes that the required cues have been previously
programmed.
 Select the Stack entity screen by pressing the stack entity button,
situated just under the right hand LCD screen and the next. The
right hand LCD is now displaying the entry screen which is similar
to that shown below:
Stack:1 {Stack 1 } Len:0
Entry:1 Cue:1 Cue 1
TP:1 XFade:As Cue --:--.-
Wait:Man 00:00:00:0 [Record] [MAKE]
Field name Value Description
Stack
0 – 100 The stack object number
Len
0 – 999 Length of the stack
Entry
0 – 999 Entry number of cue list
Cue
0 – 999 Cue assigned to entry
TP
1 – 4 Identifies which Time Part details are
displayed in the following fields:
XFade
As Cue,
Timed,
Snap
Sets the cross fade mode for the entry.
Wait
Auto,
Man,
Smpte
Sets the wait mode between entries on
manual, auto timed or Smpte timed.
 Select the required stack number.
 Press the enter button on the numeric keypad and the cursor will
move to the stack legend area of the LCD. Here you can enter an
eight character legend using the keyboard.
 Press the enter button again and the cursor will move to the Stack
Entry Number field. Ensure that this field is showing Entry:1. (All
settings set for entry 1 will be used as default in the next entries)
 Press the enter button again and the cursor will move to the Cue
Number field. Enter the cue number you wish to make entry one
and press the enter button. (The cue name will appear on the
right).
 Press the enter button until the cursor is in the Xfade area of the
LCD. Select the required Xfade type by using the rotary control.
As Cue
This uses the times which have been previously stored
against each cue in determining the Xfade time. For HTP
channels the fade time used will be the up time of the next,
or incoming cue and this will also be used as down time of
the current, or outgoing cue. For LTP channels the situation
is similar with the move time of the next, or incoming cue
being used as the overall move time. This approach also
applies to all time parts which maybe used in each of the
cues.
Timed
This will override the times stored against each cue with the
time entered against the stack entry. This operates in the
same manner as above for HTPs, with the time being the
fade down time of the current cue and the fade up time of
the next cue. For LTPs the time is used as the overall move
time. This approach also applies to Time Parts and a
separate time can be entered for each time part of the cue.
Snap
This essentially gives a cross fade time of zero seconds and
therefore the cross fade is instantaneous, a snap change.
 Press the enter button to move to the wait area of the LCD. Select
the required Wait type by using the rotary control.
