Glossary
A/D converter — An electronic device that converts analog signals
into digital signals.
Aliasing — A type of signal distortion that occurs during A/D con-
version if the sampling frequency is less than twice that of the highest
audio frequency. A/D converters employ aliasing filters to filter out
audio frequencies higher than half the sampling frequency. See also
Nyquist Sampling Theorem.
BGM (Background Music) — Music played in the background as
a backdrop to a main event. Can be used as an accompaniment, or to
create a mood.
Bulk Dump — A ProMix 01 MIDI function that allows data transfer
between ProMix 01s. Data is transmitted as MIDI System Exclusive.
Bus — In an audio mixer, a common conductor used to collect and
distribute signals. The ProMix 01 has the following buses: SEND1,
SEND2, SEND3, SEND4, ST, and CUE.
IEC958 (Consumer) — A digital interface format that is used to
transfer digital audio data between consumer type digital audio
equipment such as CD players, consumer DAT recorders, DCC, and
Mini Disc recorders. Two channels of digital audio (left & right) are
carried in one connection, usually a phono/RCA jack type connec-
tion. This format is often called S/PDIF (Sony/Phillips Digital Inter-
face Format). ProMix 01 DIGITAL REC OUT uses this format.
Channel mode — The mode in which each bank of MIDI Control
Change messages used to control ProMix 01 parameters are trans-
mitted on individual MIDI channels.
Confidence monitoring — Monitoring directly from a recording
medium to make sure that program material is being recorded cor-
rectly. On an analog tape recorder, signals are picked up by the play-
back head immediately after being recorded to tape by the record
head. This allows for confidence monitoring. It is not possible on a
tape recorder with combined record and play heads. A DAT must have
4 heads (inside one drum) for confidence monitoring.
Control Change — A type of MIDI message that offers real-time
control. Typical Control Changes include Modulation, Volume, Pan,
and Portamento. All ProMix 01 mix parameters can be controlled
using MIDI Control Change messages
D/A converter — An electronic device that converts digital signals
into analog signals.
DSP (Digital Signal Processor) — A chip designed specifically for
processing large amounts of data at high speed in real time. This type
of processor is ideal for handling digital audio data.
