Rate Pull Up/Down

Normally a synchronized audio clock is set to be
precisely 44,100 Hz, 48,000 Hz, and so on. There are
some cases where it is required to run the audio at
pull-up or pull-down rates.
The Rate Pull Up/Down options are:
• – Normal use
Off
• – If and only if the frame rate is 29.97 (DF
29.97 Up
or ND), then pull-up the audio clock rate.
• – If and only if the frame rate is 30.00 (DF
30.00 Down
or ND), then pull-down the audio clock rate.

FreeWheel

The HD-P2 FreeWheel setting lets you adjust how
many bad, missing, or discontiguous timecode frames
should elapse before dropping out of a timecode
operation (record or play). The options are from
frames, or . After a timecode operation has

started when FreeWheel is set to
be stopped or removed and it will still continue (In
this case, you have to press the
memory space or power to stop the timecode opera-
tion).

Jam Sync

When timecode is set to
Infinite
timecode source is connected, the internal timecode
generator is started. While there is a signal, the HD-P2
will continue to follow the external timecode. Should
the timecode stop, the internal timecode generator
takes over as the timecode reference until one of the
following occurs:
• clock source is changed
• freewheel setting taken off of
• power cycle
This assumes that the internal clock, or something
else, does not stop when the LTC is unplugged. You
can turn on/off the timecode (via keys) or disable/
enable timecode, and the generator will continue to
run.

Timecode Origin

When a project is created with timecode enabled, it
has an initial timecode origin of 01:00:00.00. This
defines the beginning of a 24-hour "timecode day" for
the project. If an operation hits the end of the timecode
day (e.g. 00:59:59.29, in this case), it is stopped.
Before recording audio into the project, the user can
modify the start/stop points of the timecode day to
correspond with the range of external timecode that
is expected to be used with the project. For example,
if the user is using 30 fps code, and sets the timecode
origin to 02:00:00.00, the timecode day will range
from [02:00:00.00 to 23:59:59.29] and then from
[00:00:00.00 to 01:59:59.29]. In this case, a recording
at 00:01:30.00 will be towards the end of the 24-hour
timecode day instead of near the beginning. This
makes "recording over midnight" possible in time of
day applications.

Timecode Offset

The HD-P2 can offset incoming timecode up to +/-12
hours during playback. This is useful when the user
wants to line up playback with a timecode source that
uses a different timecode range than that used to origi-
nally record the material into the project. An
selection allows the user to activate and deactivate
the offset without having to reenter the numeric offset
each time. The word
