    Quick Start Guide Quick Start Guide The 722 is an extremely powerful and fl exible portable audio recorder. Before recording, familiarity with the product is essential. Several settings should be verifi ed or set based on individual recording needs. Powering the Unit Apply power to the unit by connecting the (included) removable, rechargeable Li-ion (lithium ion) bat- tery to the back panel battery mount.

    722 User Guide and Technical Information Input Setup and Control The 722 has two inputs and two record tracks. Inputs are selectable between analog or digital sourc- es. Analog inputs are connected with the balanced XLR connectors; digital inputs can be connected to either XLR Input 1 (AES3) or the BNC input (AES3id).

    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 20: Input-To-Track Routing

    Serious damage could result. Input-to-Track Routing The 722 uses a simple, yet powerful routing scheme. The routing matrix allows each input to be routed to any track. Inputs can be routed to a single track to create mono-mixed recordings.

  • Page 21: 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 of these two-channel buses are assigned their audio sources independently, enabling the 722 to feed multiple sources with unique two-channel program.

    1 dB increments by 40 dB. 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, or post-record tracks. The headphone output is independent of the Master Output Bus and Output Bus 2—audio sources can be routed to headphones independent of routing...

    You can exit the selection process by pressing the stop or cancel (backlight) key at any time. If DONE is pressed in the fi rst headphone slot, the 722 will select a single option (Tracks A, B) for head- phone monitoring. The 10 factory presets will be erased.

  • Page 24: Headphone Playback Mode

    While giving a very good visual indication of perceived loudness, VU meters gives poor information on actual signal peaks and are virtually useless for tracking to the 722. In VU mode, the front panel meter labeling is in volume units with –20 dBFS cooresponding to 0 VU.

  • Page 25: Peak Leds

    In addition to the main LED output meter, peak LEDs show input peaks, track peaks, and head- phone peaks. Input Peak The 722 has a peak LED associated with each input. These LEDs illuminate when input signal reaches –3 dBFS. There is no user-adjustment to the Input Peak LEDs. Track Peak The 0 dBFS LED on each track can also function as a track peak indicator.

  • Page 26: Lcd Contrast & Backlight, Led Brightness

    Bit Depths The 722 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 acquisition is a signifi cant benefi...

    16 bit, meaning the least signifi cant 8 bits are discarded. Once a fi le is recorded its sample 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 environ- ment, such as an audio workstation.

    AutoPlay The 722 can be set to play back all (playable) audio fi les in a directory. Files will play back in their order in the directory. Autoplay can be set with the following options: • Disabled – auto playback is off •...

    fi les present on the medium. This reduces possibility of directory corruption and reduces the possi- bility of fragmented data 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 30: 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 31: 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 32: Testing

    If the 722 detects a fi le with a duplicate name in the destination directory, the letter suffi x, starting with “A” is added to the fi le name after the take number with poly fi les and after the track firmware v.

  • Page 33: File Management And Copying

    File Management and Copying The 722, like a computer, writes its audio recordings to a fi le system. That system is FAT32. The 722 formats its internal hard drive and Compact Flash medium as single volumes named “722”. All fi les generated by the 722 are placed in the folder (directory) named SOUNDDEV.

    File names are listed in the order they were recorded. Data fi les not native to the 722 will show in the fi le directory view but no detail will be available. They will report as “Invalid File Format.”...

  • Page 35: File Time And Date

    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 and fi le generation date are written with each fi le, make certain that the system time and date are accurately set.

  • Page 36: File Transfer - Firewire

    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.

    722 will power down—any recordings in-process will automatically stop. External Powering The 722 can be powered from clean DC power sources within a range of 10–18 VDC, 12 watts mini- mum. Connection to the 722 is through the 4-pin Hirose connector (Part # HR10-7P4P). Pin-1 of the −...

  • Page 38: Charging

    722 User Guide and Technical Information The 722 has a battery charger for the Li-on battery. The charger is active when 10–18 VDC is applied to pins 2 (–) and 3 (+) of the Hirose connector. When power is applied, the charging circuit evaluates the battery condition and supplies charging current, if necessary.
