Chapter 2: Installation and Configuration Hardware Connections The following are the primary hardware connections on a SYNC peripheral: • AC Power • Serial to a DigiSerial port on a Pro Tools core card (HD Accel Core, HD Core, or HD Native), or a serial port on a Windows computer Serial Connections Serial to Pro Tools Core Card Pro Tools systems require a serial connection between the SYNC peripheral and a Pro Tools core card.
Serial Connections in Standalone Mode for the SYNC Setup Software Utility To connect a SYNC peripheral to Pro Tools HD interfaces: (Windows Only) 1 To use the optional SYNC Setup software utility to communicate with a standalone SYNC peripheral, you need a serial connection from the SYNC peripheral to a supported Windows computer. (For compatibility information, see “System Requirements and Compatibility” on page 3.
MachineControl On MachineControl-enabled Pro Tools systems, SYNC peripherals support limited Serial Deck Control only. For full use of MachineControl option features, a direct serial connection to the host Pro Tools computer is required. Serial Deck Control Mode (Non-Linear Decks Only) A limited degree of Serial Deck Control mode is available through a connection to the 9-pin ports on the SYNC peripheral. For full Serial Deck Control, a direct serial connection to the host Pro Tools computer is required.
Character Generator for Timecode Window Dub SYNC peripherals can generate a timecode window dub on SD signals coming into the Video In port. For SYNC HD only, even when you have an HD video reference signal connected to the Video Ref connector, you can still connect an SD video signal to the Video In connector to provide a window dub. To use the SYNC peripheral Timecode Character Generator to make a window burn: Connect an SD video signal to the SYNC peripheral Video In port.
Connecting AES/EBU Devices Pro Tools and MTC To input AES/EBU clock reference to a SYNC peripheral: Pro Tools receives MTC from SYNC peripherals through its connection to the SYNC peripheral Host Serial port. This signal does not include standard MIDI timecode, but is instead a highquality, proprietary timecode signal designed for Pro Tools. A MIDI Interface is not required for Pro Tools to receive MTC. Connect the device’s AES/EBU output to the SYNC peripheral AES/EBU input.
Software Installation The following sections provide instructions to install software required to use a SYNC peripheral with Pro Tools or with the standalone SYNC Setup software (Windows only). SYNC Peripherals with Pro Tools All software required to use SYNC peripherals is installed with Pro Tools software. The availability of SYNC peripheral features depends on the version of Pro Tools software you are running. For details on features available with your version of Pro Tools, visit www.avid.com.
SYNC Peripherals with SYNC Setup Software Utility Emulating a SYNC I/O (Windows Only) (SYNC HD Only) When using a SYNC peripheral in Standalone mode, it can be controlled remotely using the SYNC Setup software utility. Updates to this utility can be downloaded from www.avid.com. To install the SYNC Setup software utility on Windows: Make sure the SYNC peripheral is connected to a serial or COM port on your computer.
Configuring a SYNC Peripheral from Pro Tools 3 Under Synchronization Device, select Enable SYNC HD (for a SYNC HD) or Enable SYNC Peripheral (for a SYNC I/O). Pro Tools HD software provides configuration controls that establish communication between Pro Tools and the SYNC peripheral. Loop Sync SYNC peripherals support the Loop Sync feature for connecting Pro Tools HD interfaces.
Configuring a SYNC Peripheral in the Session Setup Window When a SYNC peripheral is connected through Loop Sync and enabled in the Peripherals dialog, its settings become available in the SYNC Setup and Timecode Settings sections of the Session Setup window. Clock Source Session settings The Clock Source can be any device in the Loop Sync chain.
When the SYNC peripheral is not the selected Clock Source device, the Clock Reference menu in the SYNC Setup section switches to Loop Sync. For LTC clock reference, multiple choices are available from the LTC sub-menu. See “LTC and Clock Reference” on page 39. When Clock Source is an HD I/O When a Pro Tools audio interface is providing the Clock Source, it will be the Loop Master.
Speed Cal The Speed Cal indicator lights to in- dicate the status of the clock reference: • Yellow Solid: SYNC HD is locked and that the clock reference is within 0.025% of the expected rate • Yellow Flashing Fast: SYNC HD is locked, but the clock reference is between 0.025% and 4% faster than the expected rate • Yellow Flashing Slow: SYNC HD is locked, but the clock reference is between 0.
To set the session Timecode Rate: HD Video Reference Choose a rate from the Timecode Rate pop-up menu in the Session Setup window. Choose the video reference rate for the session from the Video Ref Format pop-up menu in the Session Setup window. If the session already has video, the format will be set automatically. Choosing a session Timecode Rate In Standalone mode, the SYNC peripheral Timecode Rate can be set using the SYNC Setup software utility (Windows only), or from the front panel.
The following video reference rates are available in the Video Ref Format pop-up menu: Video Reference (HD) Rate Video In Format Slow PAL - 23.976 NTSC • 720p - 24 Slow PAL - 24 PAL • 720p - 25 720p - 23.976 NTSC 720p - 24 PAL (NTSC avail) 720p - 25 PAL 720p - 29.97 NTSC 720p - 30 NTSC • 1080i - 50/1080psf - 25 720p - 50 PAL • 1080i - 59.94/1080psf - 29.97 720p - 59.94 NTSC 720p - 60 NTSC 1080i - 47.95/1080psf - 23.
Video Reference (HD) Rate Video In Format 1080p - 30 NTSC 1080p - 50 PAL 1080p - 59.94 NTSC 1080p - 60 NTSC Selecting the Transport Master The Transport Master selector in Pro Tools lets you select the device that will be controlled by the Pro Tools transport. Choices include Pro Tools and any other devices or modes you have enabled in the Synchronization or Machine Control tabs of the Peripherals dialog.
Troubleshooting Status LEDs The Locked and Speed Cal status LEDs on the SYNC peripheral front panel and in the Session Setup window may help you isolate potential problems. Incoming Time Field The Incoming Time field in the Session Setup window indicates whether or not the SYNC peripheral is receiving positional reference.
Synchronization Accuracy If you are noticing drift or lack of accurate synchronization between your devices, check the following: If your system locks up in the wrong place, make sure you have set the correct frame rate and format (NTSC or PAL) on all your devices. If your system locks up in the correct location, but drifts, check your clock signals and settings.

Parameters and Values When configuring a SYNC peripheral with the Set, Run/Stop and other parameter controls, the LED display shows parameter names, values, and other data. For a table identifying each LED abbreviation and function, see “Parameters” on page 59. Positional Reference Switch This switch selects the positional reference source, as indicated by the Positional Reference LEDs. Choices include LTC, VITC, Auto Switch Bi-phase, and Generate.
SYNC Peripheral Back Panel Video Ref Bi-Phase/Tach GPI/Pilot Video In/Out Host Serial LTC In/Out AES/EBU In/Out MTC Out Word Clock In/Out 9-Pin Out 1 9-Pin Out 2 Loop Sync In/Out AC Power Figure 2. SYNC HD Back Panel Bi-Phase/Tach/GPI/Pilot This is an accessory port for Bi-Phase, Tach, and Pilot signals (specific cables are required for different applications). This connector is also used for GPI input, output (including Fader Start), and thru signals. This port handles up to 12 V Bi-Phase.
Host Serial Port LTC In/Out The Host Serial port is a bidirectional (in/out) port to connect the SYNC peripheral to the DigiSerial Port on a HD Core card. When not being used with Pro Tools, the SYNC peripheral Host Serial port can be connected to a standard serial port on a supported computer to run the SYNC Setup software utility (Windows only). LTC In Receives a Linear Timecode (LTC) Video In/Out LTC Out Outputs linear timecode, in balanced or unbalanced analog audio format.
Word Clock In/Out Word Clock In Receives (1x sample rate) Word Clock, for clock reference purposes only. Word Clock is often used with external digital consoles and digital tape machines. Word Clock Out Outputs 1x sample rate Word Clock information (for Word-clock capable peripherals) or 256x Super Clock information. This port is configured using the controls on the front panel of the SYNC peripheral or the SYNC Setup software utility (Windows only).
Timecode Window Frame Rate The timecode display mirrors the LED Timecode Display on the SYNC peripheral front panel, displaying (in hours:minutes:seconds:frames) the timecode address of the current positional reference. This control selects the frames-per-second (fps) rate of external (or internally generated) timecode. When the SYNC peripheral is reading odd-numbered fields, the separator changes from a normal colon (:) to a period (.
LTC Output Level VITC Insertion Enabled This control adjusts the analog audio level of the SYNC peripheral LTC output, from –24 dBu to +9 dBu. When selected, VITC will be inserted into the outgoing video signal—assuming that a video signal is present at a SYNC peripheral video input, and that the SYNC peripheral is in a valid mode for inserting VITC. The only invalid positional reference modes are VITC or Auto Switch LTC/VITC. SYNC peripherals cannot read VITC and generate new VITC at the same time.
Bi-Phase/Tach Parameters Variable Speed Override (VSO) Used for specialized applications that involve film or other equipment that output BiPhase/Tach information. These parameters must be set to match the Bi-Phase or Tach source to achieve lock. Used to change (or varispeed) the rate of the SYNC peripheral internal crystal-referenced clock. This change is measured in cents, or hundredths of a semitone.

Chapter 4: Using SYNC Peripherals SYNC peripheral settings can be controlled in three ways: About SYNC Setup Software Utility Remote-Only Mode From Pro Tools Provides access to most SYNC peripheral controls from within the Pro Tools Session Setup window or the Synchronization page of the Peripherals window.
SYNC Peripheral Controls in Pro Tools, SYNC Setup Software Utility, and the Front Panel Table 2.
When a parameter value is visible Press Set once Front Panel Generator/Parameter Switches to set the value for that parameter and return the Display to timecode. The Generator/Parameter controls are labeled Set, Down, Up, and Run/Stop/Clear/Esc. In addition to their primary generator functions, these switches provide front panel access to most SYNC peripheral parameters.
Edit Mode To enter Parameter/Value Edit mode: Press Set (when timecode numbers are visible in the LED Timecode Display). The first press displays the first parameter name, “Set Gen,” (for the timecode generator). The first page of Generator Parameter controls A different parameter may be displayed, depending on the previous SYNC peripheral settings. To scroll through parameter choices: Press the Up or Down switches to scroll through available parameters.
Video and Clock Reference (SD Video Only) If you have only a single SD (standard definition) video source, and if the video source and the SYNC peripheral have a common video reference, then you can connect the SD video signal to the Video In connector.
Digital Clock (AES/EBU or Word Clock) Options To resolve the SYNC peripheral to external AES/EBU or Word Clock using Pro Tools: In the SYNC Setup section of the Session Setup window, select the appropriate digital clock reference from the Clock Reference pop-up menu. To resolve the SYNC peripheral to external AES/EBU or Word Clock using the front panel controls: Press the Clock Reference switch to select Word/AES (SYNC HD) or Digital (SYNC I/O).
LTC and Clock Reference LTC can provide both positional and clock information in the same timecode signal. LTC can be recorded onto and played back from an analog track, or a VTR audio, address or cue track. LTC cannot be read when the reference deck is stopped, or playing back at slow or fast wind speeds (roughly 10x playback speed). Pro Tools will not lock until the LTC signal is close to playback speed.
Adjusting LTC Output Level/Gain To adjust LTC output level/gain from Pro Tools: 1 Choose Setup > Peripherals and click Synchro- nization. Choose a value from the LTC Output Level popup menu. 2 3 Click OK. To adjust LTC output level/gain using the front panel controls: Press Set, and use the Up and Down switches to display one of the following: 1 • SYNC HD: LTC Level (“L7C LEUL”) – or – • SYNC I/O: LTC Gain (“L7C GAIn”) 2 Press Set.
Bi-Phase/Tach and Clock Reference SYNC peripherals are able to resolve to Bi-Phase/Tach information for use as a clock reference. Bi-Phase/Tach can synchronize positional reference, but you must provide a reference start address (see “Bi-Phase Position Trimming” on page 48 for other requirements). Pro Tools will not lock until the Bi-Phase signal is present.
Variable Speed Override (VSO) To fine-tune the speed (and pitch) of Pro Tools or any device receiving its clock reference from the SYNC peripheral, you can varispeed the rate of the SYNC peripheral’s crystal-referenced internal clock. VSO is available at any Positional Reference setting. VSO is not available from the SYNC peripheral front panel controls, but can be controlled directly from Pro Tools or with the SYNC Setup software utility (Windows only).
When Pitch Memory is enabled, Pro Tools continues to play and record at the resolved sample rate even if the Clock Reference source disappears. The SYNC peripheral retains the Pitch Memory setting, even when the unit is powered off and on again, until you change it. To configure Pitch Memory using Pro Tools: Choose Setup > Peripherals and click Synchronization. 1 2 Select the Pitch Memory Enabled option. 3 Click OK.
To set LTC as the SYNC peripheral positional reference using the SYNC Setup software utility (Windows only): Select Linear Timecode (LTC) from the Positional Ref pop-up menu. Make sure you select the appropriate clock reference, sample rate, frame rate, and freewheel duration. Also make sure the LTC signal is routed properly to the SYNC peripheral LTC In connector.
To set VITC as the SYNC peripheral positional reference using Pro Tools: In the SYNC Setup section of the Session Setup window, select VITC from the Positional Reference pop-up menu. The Positional Reference setting you choose remains set, session to session, until it is changed again. To set VITC as the SYNC peripheral positional reference using the front panel controls: Press the Positional Reference switch to select VITC.
To select Auto LTC/VITC for positional reference using Pro Tools: To use Serial Timecode as the SYNC peripheral positional reference: In the SYNC Setup section of the Session Setup window, select Auto LTC/VITC from the Positional Reference pop-up menu. The Positional Reference setting you choose remains set, session to session, until it is changed again.
Bi-Phase/Tach Starting Frame In order to use the Bi-Phase/Tach signal as a positional reference, the SYNC peripheral also needs to know the timecode address for a particular frame of film. This positional relationship is established by parking the film device at a particular frame and setting the SYNC peripheral to the equivalent timecode value using the Bi-Phase/Tach Starting Frame parameter.
To define the direction for a Bi-Phase/Tach input signal using the front panel controls: To set the pulses per frame value for a Bi-Phase/Tach signal using Pro Tools: Press Set, and use the Up and Down switches to display Bi-Phase/Tach Input Signal (“bIPH 5I6”). 1 1 2 Press Set. 3 Use the Down and Up switches to scroll parameter values: • “A LEAd b”: Bi-Phase: FWD = A leads B • “b LEAd A”: Bi-Phase: FWD = B leads A • “r–n–d LO”: Tach: FWD = B is Low • “r–n–d HI”: Tach: FWD = B is High 4 Press Set.
Compensating for Timecode Offsets You can offset the display of incoming timecode in the Pro Tools application. This is useful when you want to adjust the display of timecode to match the start time of the session (such as with source material that starts at a different time), or compensate for source material that is consistently offset by a fixed number of frames (such as with some color–corrected video masters). Pro Tools provides five different types of External Timecode Offset settings.
Requirements for Read/Regeneration of LTC, VITC and MTC LTC The external positional reference must be moving at normal, 1x forward speed (±8 %). VITC The positional reference must be LTC or Bi-Phase/Tach, at any readable speed, forward or reverse. The SYNC peripheral will not regenerate VITC if the positional reference is VITC. MTC In order for the SYNC peripheral to regen- erate continuous MTC, the external positional reference must be moving at normal, 1x forward speed (±8 %).
Generator Start Time LTC Generation/Regeneration To set the generator start frame using Pro Tools: Regenerating LTC Configure the Session Setup window as appropriate for your system and the current project. See the Pro Tools Reference Guide for more information. SYNC peripherals will regenerate LTC whenever the external positional reference is moving at normal, 1x forward speed (±10%).
Generating LTC In Generator Preset mode, the SYNC peripheral can generate LTC using either an external or internal clock reference. Make sure LTC is correctly routed and that all your other gear is properly configured before you begin. If necessary, adjust the input level for the destination device. To generate LTC using Pro Tools: 1 In the expanded Transport window, click Gen LTC. Start Pro Tools recording or playback.
The SYNC peripheral Video Out signal is connected to the destination device. The SYNC peripheral is then able to stripe the second VTR’s videotape with VITC. (At the same time, you might also want to insert a window dub. See “Generating a Window Dub” on page 56.) Unlike LTC, SYNC peripherals can regenerate VITC with both forward and reverse timecode addresses.
To regenerate VITC based on an external positional reference using the SYNC Setup software utility (Windows only): 1 Ensure that the SYNC peripheral is connected in-line with a video source and video destination. 2 Ensure that VITC Insertion Enabled is selected and that you have selected the appropriate video format (NTSC or PAL). 3 Use the VITC Generate Lines menu to configure the line pair, if necessary. 4 Select the appropriate clock reference.
Use the Down and Up switches to scroll through the parameter values and select a VITC line pair. 7 8 Press Set. Using the Positional Reference switch, select Generate. 9 Set the timecode start time. See “Generator Start Time” on page 51 for instructions. 10 11 Arm the destination VTR to record video, so that VITC can be inserted into the video signal, and be recorded on the destination videotape.
MTC Output and Idle Muting MTC is normally output whenever LTC is output. Whenever LTC output stops, the SYNC peripheral will continue to output MTC in bursts of one frame every 200 milliseconds. This allows any connected MIDI-reading device to be continuously updated as to the position of VITC or Bi-Phase (either of which might be operating at slow or still speeds). Thus, you can still use a connected MIDI device for Auto-Spotting from VITC or Bi-Phase.
To insert a timecode window into a video signal using Pro Tools: 1 Choose Setup > Peripherals and click Synchro- nization. 2 Select Enable Dub Window. 3 Configure any of the following window dub appearance settings from the corresponding popup menu: Vertical Position, Horizontal Position, Size, and Color. Vertical Position Sets the vertical position of the window dub, relative to the bottom of the video picture. The choices range from 10% From Bottom to 50% From Bottom, in 10% increments.
Sync Status Indicators in the Edit Window • Flashing slow: SYNC I/O is locked but the clock reference is more than 0.025% slower than the expected rate. Pro Tools HD 10 now provides graphic indicators in the Edit window for Video Reference, Sync Lock, and Speed Calibration. In lower versions of Pro Tools, you have to view the Session Setup window (which takes up valuable screen space) or the front panel of the SYNC peripheral to view these indicators. • Unlit: Clock reference is not within 0.
Chapter 5: Additional Operational Information Front Panel Generator/Parameter Controls This section details the parameters available from the multi-function Set, Down, Up and Run/Stop/Clear/Esc switches on the SYNC peripheral front panel. For details on the multi-function Generator/Parameter switches on the front panel, see “Front Panel Generator/Parameter Switches” on page 35. Parameters SYNC peripheral parameters are selected and edited using the four Generator/Parameter switches.
SYNC peripheral front panel display of parameters Set Generator Start Time Lets you set a start time for the SYNC peripheral timecode generator. LED Parameter SE7 6En Set Generator Start Time dI6 rEF Digital Reference SPL FrEC Sample Freq (Rate) PuLL r7E 1 Pull Up/Down 0.1% PuLL r7E4 Pull Up 4.167%, Down 4.
Base Clock VITC Read Lines Configures the Word Clock Out port. Choices are Session (1x the base session sample rate), or 256x (for Slave Clock devices). This setting determines which line pair of incoming video is used for the VITC source. To choose the VITC read lines: The base sample rate is 44.1 kHz when session sample rate is 44.1, 88.2, or 176.4 kHz, or 48 kHz when session sample rate is 48, 96, or 192 kHz.
Window Dub/Burn To set the freewheel duration: By enabling this setting, you can superimpose a window dub onto an incoming video signal. 1 Select Freewheel Length (“FrEE LEn”), using the Set, Down, and Up switches. 2 Press Set. The LED Timecode Display displays the current setting, in frames. The front panel lets you enable window dub but does not let you adjust any window options. 3 Use the Down and Up switches to scroll parameter values. 4 Press Set.
Servo Gain Pitch Memory/Hold This setting provides a user selectable LTC servo gain offset. The five choices provide different servo gain settings to reduce the effects of jitter when locking to linear timecode. The front panel Servo Gain settings correspond to the same settings available in Pro Tools: Pitch Memory is useful when resolving the SYNC peripheral to off-speed, free-running LTC.
Bi-Phase/Tach Pulses Per Frame Video Format/System Bi-Phase/Tach involve several settings, including pulse per frame. This sets the number of BiPhase/Tach pulses per frame of timecode. Selects the format (NTSC or PAL) for both the incoming and outgoing video signals. To set the pulses per frame value for a Bi-Phase/Tach signal: Select Bi-Phase/Tach Pulses Per Frame (“bIPH PPF”), using the Set, Down, and Up switches.
HD Video Format 2 (SYNC HD Only) 3 Selects the video reference rate when the Clock Reference is set to Video Reference (HD). 4 The following progressive video reference rates are available from the front panel display: • Slow PAL 23.976 • Slow PAL 24 • 720p - 23.976 Press Set. Use the Down and Up switches to select an video reference rate. Press Set. The SYNC peripheral will retain the setting, even when the unit is powered off and on again, until it is changed.
Using Fader Start To configure Pro Tools tracks for Fader Start Play and Stop: Fader Start allows faders in Pro Tools to trigger external devices to play and stop. 1 SYNC peripherals have six GPI outputs in total: two TTL-level and four relays. Together, this combination of outputs makes it possible to provide Fader Start capability. Utilization of Fader Start has specific wiring requirements. See “GPI Relay Wiring for Fader-Start” on page 94.
You may want to recalibrate a SYNC peripheral in the following situations: • If greater than 5 ppm accuracy is required. The original Oscillator Calibration value is printed on the factory sticker, on the SYNC peripheral bottom panel. • If the unit needs to be matched to a unique (nonstandard) frequency. To restore the SYNC peripheral oscillator calibration to its factory setting: • To precisely compensate for component aging. 1 – and – • To restore the original factory setting.
Restoring Factory Settings A SYNC peripheral can be reset to its default factory settings. To reset all parameters to default settings: Switch off power to the SYNC peripheral and wait at least 10 seconds. Factory Default Settings The following table lists the default settings of each parameter. SYNC Peripheral Defaults Parameter Name Default Set Generator Start Time 01:00:00:00 1 Hold both the Up and Down front panel switches and turn on power to the SYNC peripheral.
Managing and Selecting Video Inputs (SD Video Rates Only) SYNC peripherals have two independent video inputs, “Video In” and “Video Ref,” on the SYNC peripheral rear panel. These let you use one of the video inputs as a Clock Reference (the resolver sample clock master reference) and use the other input for working with VITC timecode and the character generator (window dub).
Figure 3.
Appendix A: Additional Synchronization Information Video and VITC Signals Black Burst and House Video Reference A black burst signal is essentially a “positionless” video signal. As with any “shared” video signal, you’ll want to ensure that your video feed comes from a properly buffered and distributed source, such as a video distribution amplifier, or the house video reference/black burst output of another device in the chain.
Example of VITC Timing Rule Working with Analog Machines As an example, if you are using LTC as a positional reference from a 3/4-inch U-Matic VTR, then that VTR should be referenced to the same video signal that you are applying to the SYNC peripheral.
Examples of Auto-Switch LTC/VITC The SYNC peripheral will switch to LTC for positional reference during hi-speed searching and cueing, for example, or whenever the tape speed is too high to read VITC. The SYNC peripheral will switch to VITC if LTC stops or is unavailable. This will include, for example, if a tape is paused or parked. If both LTC and VITC are available, the SYNC peripheral chooses which one to use based on the speed of playback.
Using just Word Clock, it is possible to create a “chain” of digital devices in your studio by picking one source as the Word Clock master, and configuring other sources as Word Clock slaves. Strictly speaking, Bi-Phase/Tach signals are clock reference signals, and do not contain positional information of their own. However, they do contain enough information for the SYNC peripheral to calculate positional information.
way. Fortunately, the SYNC peripheral Input Signals option allows you to choose the appropriate method (Tach: Fwd = B is Low, or Tach: Fwd = B is High). Please note that Pilot Tone contains no positional information; it is simply a clock reference. Most 1/4-inch machines have a center track for timecode or pilot.
