B
Balanced Audio Signals
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.
Bounce
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.
Bus
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.
C
Channel
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.
Chase/Lock
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.
Clip
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.
Crossfade
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.
