TL-Sync Synchronizer / Clock Generator

 

 

    The TL-Sync is a stand-alone, high-quality, multi-purpose Synchronizer and Clock Generator for use in a wide variety of configurations and situations. Providing multiple Sony 9-Pin ports, MMC, TL-Bus and TimeLine Lynx Bus, the TL-Sync can lock to a wide variety of digital clock and positional references while simultaneously generating multiple SMPTE/EBU time codes and digital clocks, MIDI time code, Super Clock (Digidesign), Word, AES clock and other high frequency clock signals.

 

 

Overview

  • Four 9-pin serial ports.

  • One multi-purpose RS-422 / RS-232 port.

  • MIDI.

  • TL-Bus port links together up to 32 TL-Sync’s for large systems.

  • Virtual Machine operation simplifies 9-pin and MMC control from DAW's and Consoles.

  • Virtual Track mapping scheme makes individual machine tracks accessible to external control.

  • Digital Clock and Frame Rate gearbox.

  • Two independent, isochronous digital clock rate generators.

  • Four simultaneously active digital clock or oversample outputs sourced from either generator.

  • Two timecode generators, cross-frame synchronized.

  • Independent LTC/MTC Reader.

  • Biphase, ADR Beeps, and GPIs for Post Production.

  • TimeLine Lynx Bus port for Lynx and KCU connections.

 

 

Features

 

 

Virtual Machine

  • The TL-Sync implements an internal Virtual Machine which responds to machine commands and can act as a master for the synchronization system.

  • Virtual Machine operation simplifies 9-pin and MMC control from DAW's and Consoles by presenting a complex set of synchronized machines as a single entity.

  • The Virtual Machine has a system of 112 Virtual Tracks into which the tracks of individual machines may be mapped, again providing simpler external control.

  • For chase synchronization the Virtual Machine itself may in turn be slaved to external timecode (LTC or MTC).

  • When multiple TL-Sync’s are linked together using the TL-Bus their Virtual Machines merge together to form a single unified Virtual Machine.

 

Digital Audio Clock and Timecode Gear Box

  • Two low-jitter, independent, isochronous digital clock rate generators, "A" and "B".

  • All pull-down and pull-up rates supported, including 24:25 and 25:24 ratios.

  • Four simultaneously active digital clock or oversample outputs sourced from either generator.

  • Oversample selections: 2x, 4x, 64x, 128x and 256x ("Super Clock")

  • System digital clock rate "A" may be locked to:
    – Internal crystal
    – Wordclock In
    – AES/EBU In
    – LTC In
    – Video (NTSC, PAL, Tri-Level)
    – Lynx Bus

  • Two timecode generators (TCG), "A" and "B".
    – synchronous cross-framing operations at all standard frame rates
    – TCG "A" may be referenced to Video

  • All digital clocks and timecodes synchronous/isochronous with each other.

  • The LTC Input may provide either or both of the system rate and the master sync position reference, and need not be the same timecode type or rate as TCG’s "A" or "B".

  • When multiple TL-Sync’s are connected with the TL-Bus, the "A" rate and "A" timecode type is shared by all units, while the "B" rate and timecode type may be set independently at each TL-Sync.

 

System Control Sources

  • Front Panel.

  • P2 In.

  • MMC In.

  • Console or Workstation In (console adaptation software modules TBA).

  • Parallel GPI Inputs.

  • Tascam RC-2424.

  • TimeLine KCU (via Lynx Bus).

  • All controls can operate in parallel and at the same time.

 

Machine Control Destinations

  • P2 Out:
    – machine types detected and loaded in traditional fashion
    – NTSC, PAL
    – 24P support
    – machine parameters may be hand-modified and stored

  • MMC Out.

  • TL-Bus, in addition to linking TL-Sync’s, may be used to directly control Tascam MX-2424’s.

  • Lynx Bus to TimeLine Lynx and Lynx-2 Time Code Modules.
