  • Page 19: Input-To-Track Routing

    722 User Guide and Technical Information Input-to-Track Routing The 722 uses a fl exible 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.

  • Page 20: Selective Input Muting

    Sampling Rate and Bit Depth When recording to WAV (or BWF fi les) the 722 generates uncompressed, PCM audio fi les at the user- selected sampling rate and bit depth. The 722 LCD calculates available recording time based on the sampling rate, bit depth, number of tracks set for recording and the selected storage media available capacity.

  • Page 21: Bit Depths

    16 bit, meaning the least signifi cant 8 bits are discarded. Once a fi le is recorded its sampling rate and bit depth can not be changed in the recorder. The 722 does not perform sample rate conversion or bit depth changes. File conversion must be done in another en- vironment, such as an audio workstation.

  • Page 22: Clock Slave

    If the 722 is slaved to external word clock, be certain that the source is stable. Loss of the word clock signal during recording can cause the 722 to revert back to its internally set sampling frequency. If this occurs, the portion of the fi...

  • Page 23: Outputs - Analog And Digital

    Outputs – Analog and Digital The 722 has two discrete 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 their audio sources indepen- dently, enabling the 722 to feed multiple audio devices with unique program content.

  • Page 24: Headphone Output

    722 User Guide and Technical Information Headphone Output The 722 headphone output is a fl exible tool for monitoring audio in the fi eld. The 722 allows the user to monitor inputs, tracks, and post-record tracks in a number of combinations. MS stereo monitoring is also available in headphones.

    File Time and Date Similar to a computer fi le system, all fi les recorded by the 722 are stamped with the time and date of fi le generation. To ensure that accurate time-of-day and fi le generation dates are written for each fi le, make certain that the time-of-day clock and calendar are accurately set.

  • Page 36: File Deletion

    Error Conditions: If a fi le is to large for the destination medium, the 722 will give you the option to skip the it or cancel copying. If an error occurs during fi le copying, the 722 will prompt to cancel the transfer. When the destination medium is full, the 722 will report the error and end the transfer.

    fi les present on the medium. This reduces possibility of corruption and reduces the possibility of fragmented audio fi les. Be certain that all fi les on the 722 drive have been backed up to another media before formatting. Once formatted, all data on the drive will be erased.

  • Page 39: Drive Failure

    The mechanical construction of the 722 is designed to minimize the transmission of shock to the hard drive. The drive is isolated from the chassis using special shock-reducing closed-cell foam. This material increases the amount of shock the hard drive can withstand.

  • Page 40: Storage Medium - Compact Flash

    Compact Flash (CF) is a practical, portable storage medium for audio recording. Its speed, reliability, and price continue to evolve to the benefi t of portable recorders. The 722 can write to and read from CF as either its sole recording medium or simultaneously with the internal hard drive.

  • Page 41: Testing

    SanDisk, and Kingston Technology cards in capacities from 128 MB and above will successfully operate in the 744T. The unit will support up to 2 TB of data. It is not feasible for Sound Devices to test all available CF cards for compatibility or maximum throughput with the 722. Use the CF trans- fer speed test to verify that an installed card can support the needed read/write speed.

  • Page 42: Formatting

    FAT32 volumes. Upon connection to an unformatted (or non-FAT32 formatted) external drive, the 722 will prompt the user to format the drive. If the drive is already formatted as a FAT32 volume the drive will be ready to be selected as a storage medium. The front panel drive LED will illuminate to show which drives are available for recording.
