Abbreviations

and Terms

Definitions

Monitor

The process of selecting one or more tracks to listen to in the headphones or
rear panel studio monitor output.

Motion

Controls

The “transport” keys on the MMR-8.

MTC

MIDI Time Code. Time code that is transmitted as part of a MIDI signal.
Because there is not enough room for the complete time code to be sent at once,
MTC counts in two frame increments.

Multitrack

A tape or solid state device that can record and/or playback more than one track
of audio at a time.

NDF

Non-Drop Frame. A type of time code that uses full frames for timing. It is
used in audio-only applications and with black and white video.

NTSC

National TV Standards Committee. The television and video format used in the
USA and Japan. The basic frame rate is 30 fps for monochrome and 29.97 fps
for color transmissions and recording.

Offset

The amount of difference between the program time code and an event. Tracks
and entire machines can be offset. Offsets are sometimes added to correct for
incorrect time code numbers on a tape or to compensate for timing delays
between machines.

Operating State

There are eight operating states of the MMR-8, Normal, Setup, Load Track,
View Track, Slip Track, Backup,Verify, and Error. These are distinguished by
the nature of the information displayed in the LCD window and by the keys
that are available while in each state.

PAL

Phase Alternating Line. The main European broadcasting standard that uses a
25 fps rate.

Phase Lock

The process where a machine is locked to reference signal (or to another
machine’s reference signal) so that its reference signal can be matched in phase
by controlling the speed of the machine compared to the other machine or to a
speed reference signal.

RAM

Random Access Memory. To convert audio from analog into digital, or vice
versa, a RAM buffer is required to allow the continuous analog audio to be
converted into “chunks” of digital data and the chunks of data from the hard
drive to be converted back into continuous analog audio.

Rate

How many ticks per second of some clock or other counter. There are various
rates used in the MMR-8 include fps (frames per second), ppf (pulse per frame,
biphase), word clock (samples per second)

Reference

The master clock. The MMR-8 uses two reference signals: a sample reference
