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.
