360 Systems DigiCart/EX - Manual (Page 37)

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/EX 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/EX 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.
R ECORD D ITHERING
• OFF
• DITHER DIGIN 24>16
Sets dithering ON or OFF for digital inputs during Record. The system does not make any
assumptions about the word size of the incoming stream. If you have selected a 16-bit record data
format and the digital input is known to be 24-bits then select the DITHER DIGIN option.
