The Varispeed Option enables the user to control and chase machines whilst in vari-speed. This option
is normally used for Audio and not audio visual productions.
When Varispeed is enabled the system is no longer locked to video but to an internal crystal oscillator.
The Timecode generator becomes the timing master for the system. If Varispeed wordclock is required
the Generator output should be connected to a suitable wordclock generator (Nanosyncs, Time
Machine, A&D Master Clock) and used to generate a wordclock reference for the studio.
When using the system with Sony protocol machines that lock to timecode they must be run as slaves
or the generator should be selected as the master when in play as follows:-

10.01 Varispeed Macro keys
3 Varispeed Macro keys are provided as follows:-
[Varispeed]:
[Dec Varispeed]:
[Inc Varispeed]:
Varispeed Enable/Disable:
Set Vari-speed:
Trim Varispeed:
Examples:
To set a varispeed value of +1.5% enter 00:00:01:50 then [Store] followed by [Varispeed]
To Set a varispeed of -1.5% (98.5%) enter 00:00:98:50 then [Store] followed by
To Set a varispeed of -1.5% alternative method using trim keys, first reset varispeed to 100% by
using [Clear] followed by [Store] followed by [Varispeed]. Enter 00:00:01:50 then [Trim -] followed
by [Varispeed].
10.02 Lynx operation in varispeed mode
The once modified the SR/MR/RM system provides the frame rate signals to the lynx module in both
normal and varispeed modes.
When in normal/varispeed mode the lynx will resolve the controlled machine wen in normal play as a
Master or Free machine. The Varispeed setting may therefor be use to varispeed a single machine
controlled by the lynx.
Note we currently have to modify the lynx as described in section 10.03.
10.03 Timeline Lynx Modification (Mark I)
There is no current support for lynx available and we have been unable to determine the serial
command controlling the reference source (if there is one). We have therefore to disable this in
hardware as follows:-
Link U50 pins 4 & 5 or Q2 base to Q2 emitter

10.00 VARI-SPEED
Macro 96 See below for use
Macro 203 Decrement varispeed in 0.1% steps
Macro 204 Increment varispeed in 0.1% steps
[Shift] followed by [Varispeed]
The varispeed may be set in 0:10% increments from 88:00% to 112:00% by
first entering the required varispeed via the keyboard and then using [Store]
followed by [Varispeed].
Varispeed may also be adjusted by entering the amount to adjust and using the
[Trim +] or [Trim -] key followed by [Varispeed].
