Menu 361 controls the P2 track arming interface.
The original P2 protocol supported up to 4 analog tracks, which was considered sufficient for the
P2 controlled video machines of the time. Setting Menu 361 to Analog A1-A4 will allow the first
four tracks of the MX-2424 to be record enabled from a controller limited to this P2
implementation.
With the introduction of digital video machines the P2 protocol was extended to include a larger
number of digital audio tracks. The default setting, Digital Audio, accounts for this
implementation of P2.
The "Local" option disconnects the MX-2424 from any track arming commands received via the
P2 port, and assumes that the operator will arm tracks at the front panel or with ViewNet.
"Local [enbl=A1]", "Local [enbl=A2]", "Local [enbl=A3]" and "Local [enbl=A4]" also use "Local"
track arming. The difference is that before any recording or rehearsing can take place, the P2
controller must first arm the specified analog track (A1 thru A4). That analog track therefore
serves as a record/rehearse enable. This feature is only useful where (a) the P2 controller has
limited track arming capability and cannot access all 24 tracks, and (b) the operator wishes the
P2 controller's EDL to document MX-2424 punch in and out activity.
Menu 362: P2 Punch Delay
The available choices are:
Off
1 frame
2 frames
3 frames (default)
4 frames
5 frames
6 frames
Menu 362 determines the delay in frames after the MX-2424 receives a command and the actual
execution of that command. The menu applies only to record, rehearse, or track arming
commands.
The "Off" setting means that the commands will be executed immediately, with no frame delay.
Video decks have always had a fixed and predictable delay between the receipt of a punch
command and the execution of that command. Traditional P2 controllers expect such a delay.
This menu allows the operator to set the MX-2424 delay to match that expected by the controller.
P2 controllers designed for manual, unsynchronized operation may have no notion of this delay,
and for these controllers the best menu setting may be "Off". Audio consoles would fall into this
category.
