Digital Recording Console 02R User's Guide
Expander – An expander is another form of automatic level control. By
attenuating the signal below the threshold, the expander reduces low-level
noise or expands the dynamic range of the recorded material. See Dynamics
Processor
F (frequency) – The center frequency of an equalizer band. See Equalizer.
Fader calibration – The motorized faders occasionally require
re-calibration in order to maintain the highest performance possible.
G (gain) – The signal gain of an equalizer band. See Equalizer.
Gain and 20dB (pad) – The analog input pre-amplifier controls. These
controls are used to optimize the signal from the input connectors. The pad
switch is used to reduce the channel gain for line level signals.
Gate – A gate, or noise gate is an audio switch used to mute signals below a
set threshold level. It can be used to suppress background noise and hiss
from valve (tube) amps, effects pedals, and microphones. See Dynamics
Processor.
IEC958 Part-2 (Consumer) – A digital interface protocol that is used to
transfer digital audio data between consumer-type digital audio
equipment such as CD players and DAT , DCC, and Mini Disc recorders.
Two channels of digital audio (left/right) are carried on a single line. A
coaxial phono/RCA jack connection is typical, but some systems use
optical interconnects.
IEC958 Part-3 (AES/EBU - Professional) – A digital interface protocol that
is used to transfer digital audio data between professional digital audio
equipment such as PCM and DAT mastering recorders, modular
multitrack recorders and other equipment. Two channels of digital audio
are carried on a single line. An XLR-type connector and a shielded cable is
typically used.
Internal Effects – The 02R is equipped with two internal multi-effects
stereo processors. These processors have a startling range of special effects
available to apply to your mix – shimmering reverbs, clean, precise delays,
flanging and chorus, and a myriad of other effects are available.
Metering – The 02R features comprehensive signal level metering. The
mono and stereo input channels, the tape and effect returns, and the
auxiliary sends and buses are all metered using the METER display
function. The control room output is metered using the dedicated
21-segment LED meters. Peak hold is available for all meters.
MIDI implementation – MIDI is an acronym for Musical Instrument
Digital Interface. It is an international standard that allows electronic
musical instruments to communicate with each other. Because of the
complexity of the 02R, it only recognizes MIDI Program Change, Parameter
Change, and System Exclusive messages. It uses System Exclusive
messages to provide bulk data transfers as well as controller changes. It
also reads MTC (MIDI timecode). See Timecode.
