RECORD SAMPLE RATE
Options if Record Audio Source is set to ANALOG:
• 44100
• 48000
• 88200
• 96000
• REFIN RATE
• DIGIN RATE (BNC)
• DIGIN RATE (XLR)
DigiCart/E will convert analog signals to digital data at a sample rate selected here. Internal clock signals
are used, except for the Ref In Rate and Dig In Rates, which are external sync sources. Ref In is the AES-
11 BNC connector. Dig In is selected to be one of the digital audio inputs.
Options if Record Audio Source is set to DIGITAL:
• AS RECEIVED
• CONVERT TO 44100
• CONVERT TO 48000
• CONVERT TO 88200
• CONVERT TO 96000
• CONVERT TO REFIN
When set to “AS RECEIVED”, DigiCart/E will use the AES data stream clock as its sample rate.
When “CONVERT TO a specific sample rate” is selected, the recording will always be made at this rate. If
the incoming digital audio sample rate is not already at this rate, the sample rate converter will be
automatically switched into the data path to obtain the specified rate.
Digital audio presented at any sample rate may be converted to match an external reference frequency
during record. Setting this menu item to “CONVERT TO REFIN” will place the SRC in the input path and
use the externally supplied signal to clock the input rate. RefIn is the AES-11 BNC connector.
The recorded sample rate of the current file is displayed on the LCD. Whenever the SRC is switched into
the signal path, the SRC indicator on the front panel will illuminate. The EXT SYNC indicator on the front
panel will illuminate if the sync source is set to an external source.
Some of the RECORD SAMPLE RATE options may be suppressed depending on the current RECORD
DATA FORMAT. For example, if the AC2 compressed file format is selected, the sample rate is limited to
48000 only. Also, the 88200 and 96000 rates are available only if the 24-bit WAV format is selected.
R ECORD D ATA F ORMAT
• 24 BIT WAV
• 16 BIT WAV
• 16 BIT DC2
• 16 BIT AC2
• 24 BIT DIGITAL DATA
Sets the data format for the recorded file. DigiCart/E will normally record in either 16- or 24-bit linear
stereo WAV format. Additionally, recordings can be made in 16-bit linear DigiCart (DC2) format, or 16-bit
AC-2 format.
See Appendix E for details on using the 24Bit Digital Data format. This can be used to record encoded
signals such as Dolby E.
