24 frames

The standard film frame rate per second.

The standard PAL and SECAM video frame rate per second.

29.97frames The standard NTSC video frame rate for color broadcasting per second.

30 frames The standard audio-only and black and white video frame rate per second.

AES/EBU 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.

Autolocator 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.”

Biphase 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.

Bus 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.

Calibrate 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.

Capture 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.

Chase 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.

Clear A function to remove audio between the In and Out times on one or more tracks of audio.

Clip 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.
