RECORDING
Both 47.952 and 47.952kF settings use a record sampling rate of 47.952 kHz,
0.1% lower than 48 kHz. The 47.952kF mode, however, identifies the file as
being recorded at 48 kHz.
When using 47.952kF sample rate, set main menu option TIMECODE > Frame
Rate to 23.97ND or 29.97ND. When set to 23.97ND, files will be stamped with a
frame rate of 24. When set to 29.97ND, files will be stamped with a frame rate
of 30ND.

MP3 recording is not allowed in “F mode”.
Setting the Bit Depth
The 664 records 24 bit WAV files by default. Bit depth defines the digital word
length used to represent a given sample and correlates to the maximum
dynamic range that is represented by the digital signal. Larger bit depths
accommodate a wide dynamic range.
To set bit depth:
1. Press the MENU button.
2. Turn and press the Headphone encoder to select RECORDER > Bit Depth.
3. Turn and press the Headphone encoder to select 24 or 16.
i
The bit depth value is stored in file metadata.
Setting the Pre-Roll
Pre-roll buffering is available on the 664 to help prevent missing record cues or
up-cutting takes. By default, the pre-roll time is 0 seconds (off). When active,
pre-roll begins recording at a set number of seconds preceding the record but

ton being pressed.
To set pre-roll time:
1. Press the MENU button.
2. Turn and press the Headphone encoder to select RECORDER > Pre-roll
Time.
3. Turn and press the Headphone encoder to select a value (0 s to 6 s).
i
While a pre-roll time may be set regardless of the timecode mode, pre-roll is
ignored whenever timecode mode is set to Record Run. Additionally, when the
mixer’s timecode mode is set to either External Timecode Auto Record, or External
Timecode Continuous Auto Record, pre-roll is only applied within the Hold Off
period and never before receiving rolling timecode value from the master external
timecode source. This prevents possible overlapping timecode numbers between
