Definitions
The standard film frame rate per second.
The standard PAL and SECAM video frame rate per second.
The standard NTSC video frame rate for color broadcasting per second.
The standard audio-only and black and white video frame rate per second.
Audio Engineering Society/European Broadcasting Union. The two main
organizations that set the standards for audio production. Digital audio
connections are often referred to as AES/EBU since these organizations
standardized the digital audio interconnection methods.
An analog tape function to position the transport to previously marked
locations that is emulated in the MMR-8 using the LOC key and a register or
memory location to instantly locate the "play head."
The two-pulse sync signal generated by a film transport that the MMR-8 uses
to generate time code or feet & frames timing. The MMR-8 can also generate
biphase signals to control a film transport.
Any signal that is daisy chained between multiple devices. In the case of the
MMR-8, there are two main buses: the MMR bus and the Lynx Bus.
Adjusting a signal to match a reference or standard. The MMR-8's inputs can
be calibrated so that a +4 dBu signal will correctly drive the MMR-8, and the
outputs can be calibrated for a +4 dBu output from the MMR-8. In these cases
the calibration references are the level meters.
During play or stop saves the current time code into the bottom line of the LCD
display for subsequent saving to a memory or position register.
The process whereby one device controls another device to synchronize their
playback. Chase implies there is both a synchronization signal as well as a
device control signal.
A function to remove audio between the In and Out times on one or more
tracks of audio.
Indicates the maximum signal level has been exceeded going into the analog-
digital converter. Typically this will cause severe distortion (popping, snapping,
crackling sounds) in the output signal.
