Problem: The E/G/G+ Series mix computer operating on SSL SL4/6/8000 consoles uses switch/relay closures to control the master recorder's transport, and reads timecode back off tape to lock the automation. However, the computer also requires tach pulses and direction information to follow the machine position as the autolocator can't read LTC during fast wind. This is all achieved via an SSL parallel connection (S29E) commonly employed on traditional multitrack tape recorders. This protocol is normally omitted from contemporary tapeless and videotape-based devices, which generally incorporate high speed serial connection protocols instead.

Solution: The Whizzer directly interfaces to the SSL E/G-Series parallel machine control connection, takes commands from the console's transport keys and provides switch tallies in return. It also produces the required timecode, tach and direction signals.

With a built-in timecode generator, internally crystal referenced or resolved to an external video signal, The Whizzer is a true "Virtual Machine", able to control any device that can chase timecode (be that LTC or MTC). All common audio frame rates are supported.

Additionally, The Whizzer can be employed as a frame rate converter, as it will output a different frame rate from the incoming signal.
