Definitions
Time Code Generator. A device to create the 80 bit time code signal for
recording onto a video or audio tape. The MMR-8 contains a built-in generator
which is always sending out TC when the MMR-8 is playing.
Time Code Reader. The circuit in the MMR-8 that reads incoming time code
from the VITC or time code inputs. Typically used to slave the MMR-8 to
another time code generator's output.
The end of the track's audio.
Can refer to one of the audio channels in the MMR-8, but typically it refers to
the edited audio for one track of audio on the reel.
The process of selecting which tracks an action affects through using the SEL
key for that track.
A generic reference to any audio, video, or film device that mechanically
"moves tape" or electronically plays audio or video.
The process of adjusting the time code using the Wheel.
The process of releasing the removable hard drive from the MMR-8 so that it
can be removed.
When any MMR-8 Setup parameters have been changed, the new settings can
be saved in a User Settings File (menu 900). Ten User Settings are available.
Also known as house sync, it is generated by an extremely stable video source
and consists of black burst, sync bars, or composite video. It's used as a timing
reference to synchronize video devices throughout a video facility.
Audio tracks that are "stacked" on top of one another so that alternate takes can
be kept at hand. Only the track on top will actually play back.
Vertical Interval Time Code. SMPTE/EBU time code that is recorded within
the video signal on a VTR. It has an advantage over LTC in that it can be read
during fast searches and even when the video machine is paused since the
rotating VTR heads are always reading the video portion of the tape.
Variable Speed Oscillator. Indicates that the audio is not being played back at a
"standard" playback speed, but is rather playing back at an off-speed for an
effect or to compensate for incorrect timing between devices.
The digital audio clocking signal (44.1 or 48 kHz most commonly used) used to
synchronize audio devices.
The rotary encoder on the MMR-8 front panel that can be used to trim, jog, and
shuttle audio, in addition to being used to scroll through the Setup Menus and
menu choices.
