  • Page 22: Sampling Rate And Bit Depth

    • 48.048kF -file stamped at 48 kHz Bit Depths The 702 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

    Without dither, 24 bit audio is truncated to 16 bit, meaning the least significant 8 bits are discarded. Once a file is recorded its sampling rate and bit depth can not be changed in the recorder. The 702 does not perform sample rate conversion or bit depth changes. File conversion must be done in another en- vironment, such as an audio workstation.
