MT8XII—Owner’s Manual
Glossary
Bouncing
—See Ping-Pong.
Bus
—A common conductor used to collect and distribute audio signals. MT8XII has four
Group buses that feed the tracks, a Stereo bus consisting of left and right channels, two AUX
buses for the AUX SENDs, and a stereo CUE bus for the cue monitor.
Capstan
—The cylindrical shaft of the capstan motor, which is used in conjunction with the
rubber pinch roller to drive the tape at a constant speed.
Clipping
—The unwanted distortion effect of overloading an audio circuit with a signal that
is too large. Care must be taken when setting the MT8XII GAIN controls so as not to overload
the recording circuits. See Recording the First Track on page 15 for more information.
CUE Monitor
—The cue monitor allows you to monitor individual tracks as they are being
recorded or played back. In Record Pause mode and during recording, the CUE monitor source
is the signal being recorded (i.e., the input signal). For playback, the CUE monitor source is the
tape signal. This is useful with the punch in/out functions, because you can monitor the
recorded signal up to the specified IN point, and then the new signal that’s being recorded up
to the OUT point.
DAT
—An acronym for Digital Audio Tape. DAT recorders are especially popular in recording
studios for recording the final stereo mix.
dbx Noise Reduction
—A noise reduction system for improving the noise performance of
analog tape recorders. During recording, pre-emphasis and 2:1 compression are applied to sig-
nals. During playback, 1:2 expansion and de-emphasis are applied to restore signals to their orig-
inal form. Because the tape hiss was not present in the original signal, it is greatly reduced by
this process.
Demagnetizer
—A hand-held device used to demagnetize (also called degauss) tape heads
and other metal parts that come into contact with a moving magnetic tape.
DI (Direct Inject)
—A technique for connecting an electric guitar or bass guitar directly to a
mixer. The high output impedance of the guitar is matched with the low impedance of the mixer
input using a DI Box. Some instrument amplifier’s feature a DI connection.
EQ
—An acronym for an audio equalizer. MT8XII input channels feature three-band EQ with
a sweepable MID band.
Footswitch
—A foot operated switch. On the MT8XII, an optional footswitch can be used to
perform manual punch in/out.
FSK (Frequency Shift Keying)
—A type of synchronization signal that uses frequency shift
techniques. An FSK synchronization signal can be recorded on Track 8 of the MT8XII. During
playback, the FSK signal is converted to MIDI Clock signals to control a MIDI sequencer. An
optional FSK/MIDI converter, such as the Yamaha YMC10, is required for this.
Group
—A group allows several input signals to be mixed together and recorded to a single
track. For MT8XII recording, input signals are assigned to a group. From there, they are sent to
the tracks for recording. The overall level of group is controlled by the GROUP MASTER level
control.
Line-Level Signal
—A signal in the range from –20 dB to +20 dB. These are essentially
high-level signals. Most audio equipment outputs signals at line level. All MT8XII inputs and
outputs support line-level signals. Contrast with Low-Level Signal.
Low-Level Signal
—A signal in the range from –100 dB to –20 dB. Microphone and electric
guitar signals are in this range. MT8XII MIC/LINE inputs support low-level signals. Contrast
with Line-Level Signal.
