  • Page 20: Input-To-Track Routing

    Input-to-Track Routing The 702T uses a flexible routing scheme to assign inputs and tracks for recording. The input matrix allows any input to be routed to any recording track. Multiple inputs can be routed to a single track to create mono-mixed recordings.

    See Time Code section for more information about the 48.048F, 47.952F, and 96.096F rates. Bit Depths The 702T records at bit depths of either 16 or 24 bit. 24 bit recording provides greater dynamic range and addition headroom for signal peaks relative to 16 bit recordings. 24 bit recording (versus 16 bit) is a significant benefit for field production audio tracks.

  • Page 23: Word Clock

    If the 702T is slaved to external word clock, be certain that the source is stable. Loss of the word clock signal during recording can cause the 702T to revert back to its internally set sampling frequency. If this occurs, the portion of the file recorded after the loss of word clock may not play back at the prop- er speed.

Link (control link) connection allows multiple 702T, 702T, 722, and 744T recorders to be connected and clocked together. The C. Link also enables the CL-1 Remote Control and Key- board interface to control the 702T with an attached keyboard or via switch closures.

  • Page 25: Outputs - Analog And Digital

    Outputs – Analog and Digital The 702T has two independent output buses , the Analog Output Bus (Bus 1) and the Digital Output Bus (Bus 2). Each side (left and right) of the two-channel buses are assigned audio sources indepen- dently, allowing the 702T to feed multiple audio devices with unique program content.

    The 702T generates SMPTE time code from this number and extrapolates it based on the time code frame rate for playback. All files generated by the 702T have time code numbers begin on the 0 frame (or 02 in DF modes). If necessary, pre-roll is dynamically applied to accomplish this. This simplifies synchronization in post-pro- duction.

  • Page 32: Frame Rate

    Sound Devices Wave Agent Beta for Mac OS and Windows computers allows users to change the Frame Per Second Stamp of any file. This is useful when the wrong Frame Rate was selected at the time of re- cording.

  • Page 34: Time Code Hold Off

    When external code advances, the 702T enters record mode automatically. When the external code is stopped, the 702T generator pauses and recording is stopped. If the external time code is removed the internal generator continues to run to preserve continuous time code. Useful for time code transmission over RF where RF “hits”...

    CompactFlash, substituting the external drive menu selection for the CF. After recording to an external drive has stopped, it may take several seconds for the 702T to finish “housekeeping” on drive. This is especially true when recording to DVD-RAM disks, which generally have slower throughput than hard drives.

  • Page 55: Firewire Bus Powering

    The six-pin FireWire port on the 702T provides power for bus-powered FireWire drives. The follow- ing conditions should be observed when connecting to bus-powered drives. • Bus powering a drive requires external DC powering of the 702T. The 702T cannot operate bus- powered drives from an attached Li-ion battery.

  • Page 56: File Transfer - Firewire

    The 702T’s FireWire (IEEE-1394) port makes transfer of recorded files to a computer quick and easy. When connected, the CompactFlash card of the 702T will mount to a Mac OS X or Windows comput- er as a local, removable mass storage devices. Using Mac Finder, Windows Explorer, or any other file utility, files can be copied, read, and deleted directly to and from the 702T Compact Flash card.

  • Page 57: Powering

    In Windows, right-click the drive icon and select “eject.” The cable between the computer and 702T can now be disconnected. If a future connection is going to be made the cable can be left connected.

  • Page 59: Power-Up Messages

    The best determination of your run time is to experiment with a given record- ing setup. The 702T power consumption varies over a range between 4 W to 20 W (12 volts), depending on ac- tive functions. The following functions have the most significant affect on power consumption: Inputs Active analog inputs increase power consumption.
