ALANCED
Signals that are carried on three-conductor cables, with two of the conductors carrying
the same signal 180° out of phase and third as ground. Balanced connections usually cost
more than unbalanced connections, but are less susceptible to picking up hum and
interference with low-level signals.
B
OUNCE
Bouncing means taking audio from one track and placing it on another. The term,
sometimes called "bouncing down," also describes the process of mixing several tracks
onto one or two.

A bus generally refers to any common signal pathway. In a mixer, a bus is usually a wire
that is or can be made common to the outputs of any or all channels in the mixer.
Examples of buses include the main stereo mix, sub-mixes, monitor buses and aux sends.

HANNEL
In audio, a channel is an internal audio path maintained separately from other audio
paths of identical function. Mixer input strips are examples of channels, but an audio
snake also has channels.

HASE OCK
Chase/Lock refers to a tape machine's ability to read incoming timecode, locate its
tape to the position indicated by the timecode, and synchronize playback to the
incoming timecode.

LIP
In the analog world, clipping occurs when the input to a circuit exceeds the gain of the
circuit. The circuit passes the signal at its maximum value. All input values exceeding
the maximum value are "clipped." The result is audio distortion. In digital audio,
clipping occurs when the input to an A/D exceeds the voltage represented by the
maximum number the A/D is capable of transmitting.
C
ROSSFADE
A crossfade is a gradual "dissolve" between two portions of audio; one segment of audio
fades out while the other fades in. When punching in on the XT20, the audio on tape is
faded out while the new audio which is being recorded is faded in.
D
DAT
Digital Audio Tape. This term has come to mean specific digital audio tape recorders
that use cartridges smaller than those of a standard cassette, and which record two
tracks of digital audio (and sometimes timecode).
D I/O
IGITAL
Input and output connections where signals passed from one stage to another remain in
the digital domain. The XT20 has digital I/O connectors that carry digital data for all
eight tracks.
D/A D
OR
The device that converts digital signals back into an analog format so that they can be
heard.
