Chapter 7 Advanced Features This manual describes the functions available with the standard Keyboard Control Unit (KCU) 080 series software. This chapter describes those functions uniquely available in other configurations, including KCU 600 and KCU 300 series software. The Advanced Features chapter has the following product sections: Varispeed (KCU 600 series software) •...
Page 108: Varispeed (Kcu 600 Series Software)
Advanced Features Varispeed (KCU 600 Series Software) With the KCU, Lynx-2 modules will operate both X-Frame rate and Varispeed synchronization. Varispeed synchronization permits machines to be locked together and run at different speeds to allow time compression or expansion. Varispeed synchronization allows many operational features: Tapes that have different running times can be fitted together.
Page 109: Varispeed Pivot Points And Offsets
Advanced Features To varispeed a tape, varispeed must be turned on and a varispeed source sync point marked. The KCU detects Lynx-2 modules and Lynx modules fitted with V600 on the Lynx bus, and switches for X-Frame and Varispeed operation automatically. In some instances when using the KCU, subframe amounts appear in the time code registers.
Page 110 Advanced Features Example of Pivot Points In this example, the varispeed pivot point is at 00:00:00 (no offset has been entered). There are two tapes with a zero offset. The master machine is running at standard speed, and the slave running with a +10% varispeed.
Page 111 Advanced Features Machines running in varispeed can be offset by all standard methods. The offset can be entered manually, captured, or calculated from sync points. Offsets can be recalled and trimmed dynamically, if required, using the [+] and [-] keys or the Jog/Shuttle wheel.
Page 112: Varispeed Options Menu Differences
Advanced Features When the reference sync or edit in points are changed, all machines with active source sync point registers will have their offset recalculated and reposition. The source sync point is active if the [SRS SYNC] key LED is on in solo or status modes. If you do not want a particular slave machine offset to recalculate, the source sync point for that machine should be made inactive by holding the [CLR] key and pressing the [SRC SYNC] key, before...

System Supervisor Unit (KCU 300 Series Software) With the System Supervisor Unit (SSU), the KCU becomes a powerful editor/controller within console and automation systems. The SSU becomes the central communication hub of a TimeLine machine control system. Installing the SSU In installation, the KCU and Lynx modules are all routed through the SSU.
Page 117 Advanced Features Connecting the System Supervisor Unit Instead of daisy-chaining Lynx modules from the KCU power supply, the ES bus software of the KCU requires that the KCU be connected to the SSU. The Lynx modules are daisy-chained from the RS422 port of the SSU. 1.

Page 127 SMPTE Made Simple The Time Code Tutor from TimeLine Introduction When the television broadcast industry moved from film and live performance to prerecorded video production, a method was re- quired to reliably synchronize and edit the new medium. Historically, film rushes were lined up at the clapper board and rubber stamped with footage numbers, and by default film was mechanically held in sync by the sprocket holes.
Page 128 The correct solution is to use SMPTE time code a TimeLine synchronizing system. It works like this: a TimeLine Lynx or Micro Lynx generates time code that is recorded onto the audio tapes. The time code is then used as a common reference point, the “glue”...
Page 129 Appendix Locking to Picture Suppose you have footage on videotape and you need to create an audio track to go with it. It could be music, dialog, effects, or all three. How do you lock the sound to picture? Use SMPTE and a Micro Lynx or two Lynx modules, exactly as de- scribed in the previous audio example.
Page 130 Mix Automation and More If you have a MIDI sequencer and some synthesizers that you want to lock to your multitrack tape or to picture, the TimeLine Micro Lynx can translate SMPTE time code into the MIDI data that the sequencer needs to lock to tape.
Page 131 Appendix Figure Appendix A-4. Complete Studio System How Does SMPTE Do It? If you know precisely where a piece of program is and how fast it is playing, then it is possible to use this information to control other machines so that they are all in the right place at exactly the same time.
Page 132 Appendix tape speeds up, the frequency will increase. A controlling device, tied into the tape machine’s capstan motor, senses the difference between the reference tone and the pilot tone on tape; and varies the speed of the tape machine motor to make the two match up again.
Page 133 Appendix SMPTE: What You Can Do with a Speed and Position Reference This is where SMPTE time code enters the picture. As we said, SMPTE indicates not only tape speed, but also tape position. SMPTE time code is a complex digital signal, equivalent to the simple, analog pilot tone signal with a unique number assigned to each cycle of the sine wave.
Page 134 Appendix The time code reader uses the direction sense bits to determine • whether the tape is running forwards or backwards. The sync word is a series of preset 1’s that allow the speed and • phase of two time codes to be read and compared by the Lynx or Micro Lynx module to establish synchronization.
Page 135 Appendix Phase Alternate Line (PAL) In Europe, the standard wall current frequency is 50 Hz. Thus we have another format: 25 frames-per-second or the PAL format, the standard for European color television. Drop Frame (DF) What about American color TV? When it was invented by RCA, they reduced the American black and white frame rate of 30 frames-per-second to 29.97 frames-per-second, to allow both color encoding and compatibility with existing black and white televi-...

Page 137 Appendix VITC uses a 90-bit data word instead of the 80-bit data word used by LTC. The extra bits are used to provide error correction and to prevent bad time code values from being read. VITC allows accu- rate reading of tape position even when the tape is stopped in freeze frame, which is something that LTC can’t do.
Page 138 As soon as one complete SMPTE address is transmitted, the MTC generator updates the time code by 2 frames and starts again. The TimeLine Micro Lynx and Lynx System Supervisor Unit can take SMPTE from a master tape and generate MTC. Thanks to...
Page 139 In the early days, a different device was quite often required to perform each of these functions. Today, TimeLine has several products that perform them all: the Lynx Time Code Module with a Keyboard Control Unit, compact, high-end, high performance units;...
Page 140 Appendix With digital audio machines, the sample rate or word clock must be locked to the time code. This is normally done by using a video sync signal as a common timing reference for the generator and the digital machine. Set both to “EXT VID” before printing time code.
Page 141 Jam sync provides the resulting program with continuous time code. TimeLine’s Micro Lynx and Lynx both have manual and automatic jam modes, that quickly and simply let you repair or create new time code tracks to overcome the problems that are detected with bad code.
Page 142 Phase or Sync Lock Phase or Sync Lock emulates the old control track or pilot tone method of synchronization. The TimeLine system reads the time codes and synchronizes the transport, taking into account any de- liberate offsets. Once the system is locked, the slaves only use the speed information that is derived from the time code, and specific time code addresses are ignored.

These ATRs are locked to the video master using a TimeLine system controller, such as the Keyboard Control Unit or Console Control Unit. Then the multiple audio sources are balanced by a mixing console to provide a finished audio master for the program.
Page 145 In short, just about every device in the recording studio − tape ma- chines, consoles, effects processors, and electronic instruments, can now be automated using SMPTE, and MIDI, and the appropriate TimeLine equipment. Thus the Electronic Recording studio is created. Figure Appendix A-11. The “Modern” Electronic Studio...

The DAW records, edits, manipulates and mixes multiple tracks of audio in a single digital environment. Like the biosphere, it’s a self contained, self- sufficient system;...
Page 147 Appendix It’s even possible to varispeed the master tape. The Digital Audio Clock Card automatically adjusts the ACGs word clock rate. If the tape speeds up or slows down, the DAW will adjust to match the new play speed (within the limits of the disk system). As we enter the digital era, time code continues to be an impor- tant, practical solution to multiple equipment communication and control.
