Glossary

1st unit, 2nd unit
On this system, these terms are used to distinguish between two
processors (when two processors are used). The processor that is
connected to the console via VM link is called the 1st unit, and the
second processor that is cascaded is called the 2nd unit.

Absolute recording

One method of recording automix, in which fader or knob
movements are recording just as they are operated.

Active sensing

A MIDI message that is used to prevent problems such as "stuck
notes" occurring on a sound module when a MIDI cable is
disconnected or broken. This message is transmitted at regular
intervals from MIDI OUT. Once a device that is able to detect this
message has received it after being powered-on, failure to receive
any message for longer than a certain interval of time will be taken
to mean that a cable has been disconnected or broken. When this
occurs, all sound will be halted. (On this system, this message is
only transmitted.)

AD converter

A device that converts an audio or other analog signal into a digital
signal.
DA converter
ADAT
A product line of Alesis multitrack recorders compatible with the
standard for digital multitrack recorders created by Alesis
Corporation (USA). S-VHS video tape is used as the storage
medium. If the VM-24E (I/O expansion board: sold separately) is
installed in the processor of this system, bi-directional multi-
channel digital connections with, and remote control of, the ADAT
are supported via DIF-AT (sold separately).
* ADAT is a trademark of Alesis Corporation.
AES/EBU
AES stands for Audio Engineering Society, and EBU stands for
European Broadcast Union. "AES/EBU" standard refers to a
technical specification that was created by these two bodies.
References to AES/EBU format normally indicate a transmission
protocol for digital audio (the audio portion of a digital VCR
signal).
Algorithm
On this system, the structures on which effects are based are called
"algorithms." Some algorithms connect two or more effects such as
reverb or chorus in series, and can be selected as desired. 39 types
are provided for effects 1–8, and three types for master effects.
Effects
Analyzer
On this system, refers to the built-in spectrum analyzer function.

Attenuator
A collective name for any circuit that reduces an excessively strong
signal to an appropriate level. This is used to prevent input
overload distortion from occurring in subsequent circuits. The
digital attenuators in the input section of this system allow the
attenuation to be adjusted in a range of 0 dB – -42 dB. To maximize
the sound quality, it is desirable to use only the least amount of
attenuation required.
Automix
A function that records mixer settings and operations as data
(either internally or on an external sequencer) along with the
progress of the song on a sequencer or recorder. Mixer operations
can be reproduced later as the song plays back, for automatic
mixing. Since operations can be recorded separately for different
channels, and since recorded data can be edited in detail, you can
create complex mixes that would be difficult to perform manually.
Used mainly during mixdown. Sometimes called "compu-mix."

Automix function

A function that allows you to record continuously variable settings,
such as fader or knob movements (controlling volume, pan,
channel on/off, etc.), and then play back these movements as many
times as desired. This recorded content is collectively referred to as
the "automix," and individual settings that make up the automix
are referred to as "data."
Auto punch-in
The action of re-recording an automix over a previously specified
area.

Auto wah

An automatic version of the "wah pedal," used mainly with electric
guitars, which makes pedal operation unnecessary. The peak
frequency changes automatically in response to the level of the
input signal, producing a "wah wah" effect.
Backup
In general use, this refers to the action of creating a copy of data on
another storage medium as a precaution against loss of data due to
accident or inadvertent operation. On this system, the term refers to
the action of copying all user libraries of the console to a memory
card.

Balanced connection

A method of transmitting signals using three electrical conductors
(two signal lines –hot and cold – and an independent ground). The
transmitting device sends the same signal to "cold" and "hot" with
reversed polarity (+/-). The receiving device receives the signal
using a circuit that subtracts the cold signal from the hot signal.
This cancels any noise that may have entered the line during
transmission, allowing noise-free transmission of low-level signals
over long distances. This method is usual on professional and
broadcast equipment. Most inputs and outputs of this system also
use this method. The input/output jacks are normally XLR
connectors or TRS phone jacks. If a conventional TS-type plug
(used with shielded instrument cables etc.) is inserted into such a
TRS jack, it can be used as an unbalanced connection.
