Multi Machine Synchronizer Set Up; The Sr-4 As A Multi-Machine Synchroniser; Block / Sr-3 Block; Timecode Output - CB ELECTRONICS SR-3 User Manual

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 17 System 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.

1.01 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.
1.02 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.
1.03 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.
1.04 SR-4 TIMECODE INPUT
The SR-4 timecode input may be used as a remote timecode master. All four machines may be
slaved to this timecode source. In order to use the SR-4 timecode input a macro key must be used
to display the timecode (Macro 113).

1.10 Setting up the System

1.11 Defining the Master

Any machine on the system may be defined as the master including the generator or the reader. The
master machine is defined using [Shift] followed by a machine key (A, B, C, D, E (SR-24)), [Reader]
or [Generator]. Once the master has been defined and offsets set for all the slaves the master machine
may be changed as required. Note: on MR systems only machines controlled directly by the controller
may be defined as a master machine and not machines controlled by the MR-3's.
The master of a multi-machine system is the machine to which all commands are sent. The other chase
enabled machines then follow the selected master.
The master is the machine over which the user has direct control. Each user has his own reasons for
selecting a particular machine as master, here are some:-
1) Film because it is the slowest.
2) Video so that the user can jog the picture directly.
3) The record machine so that it is first to lock.
4) A machine that slaves badly or not at all.
