Once configured as an input the following changes are made to the unit.
1) The controller connected to port A will control the currently selected master (B, C, D).
2) Key [A] will become a local Switch, when the LED is illuminated this will enable control from port A.

1.14 Setting the Pre-Roll, Start Time, Loop Delay, Post-Roll, Record Advance and
End Time
To Set the Pre-Roll, type in the required pre-roll, then press [Shift] followed by [Store] followed by
Reverse Play [ < ].
To check the Pre-Roll depress Recall Followed by Reverse Play (<).
The Pre-Roll is used with Locate when using multiple machines to allow time for the slave machines to lock. To locate without Pre-Roll use Shift followed by Locate.

Start Time use the Rewind (<<) key instead of the Reverse Play key.
The Start time is particularly useful when using open reel or film machines, in rewind when the tape is within approximately 1 minute of the start time a locate to start time command will be issued to the machine.
Loop Delay use the Stop key.
Post Roll use the Play key.
Record Advance use the Record Key.
End use the Forward Wind (>>) key.
2.0 Multi-Machine Synchronizer Set Up
The SR/MR series of synchronizers offer two forms of synchronisation using either the SR/MR synchronizer or where available the machine's built in synchronizer. The user interface is identical. The decision "which type of synchronisation to use" depends on the users requirements and the technical details of the machine and the installation.
When a new machine is connected the a system parameter (Unit | Chase | Menu 18 Default Chase
Type) determines which type of synchroniser to use if there is a choice. Once connected the user is free to change the synchroniser type. The user selection will only be changed after a hard reset or if the machine connected to the port is changed.
2.1 The SR-4 as a multi-machine synchroniser
Please ensure that you have a copy of the drawing SR-4 Block / SR-3 Block whist reading this section.
The SR-4 may be used as a 4 machine remote control only, however because control of both offset and chase are included the SR-four may be used as a 4 machine synchroniser. One machine, the timecode reader, or the timecode generator may be chosen as the master. The remaining machines will slave to the selected master.
For serial controlled machines a single SR-4 can replace five Timeline Lynx II modules and a KCU controller. Where parallel controlled machines are used your existing Timeline Lynx I/II, AK ES-1.11,
Studer TLS4000, or AS Zeta 3 synchroniser module may be used with the SR-4.
2.2 SR-4 BLOCK / SR-3 BLOCK
This diagram shows a typical SR-4 installation, the four machines may be any selection of 9-pin controlled machines. Note the Video Reference is sent to all machines.
2.2.1 SR-4 TIMECODE OUTPUT
The SR-4 timecode output follows the position of the selected master machine (including the SR-4 timecode input). The timecode generator position is calculated as follows:- [Timecode Output] =
[Master Position] - [Master Offset]. Including the master offset in the calculation allows the user to change the master without having to update all the slave offsets.
The timecode generator output is also used in the perfect machine mode to provide a timecode master in a tapeless studio.
