01X Terminology
■ Attenuator (ATT)
After A/D conversion, input signals (pre-EQ level) can be
attenuated using this control. This is used mainly in the EQ
section to prevent the signal from clipping and to adjust the
level so that fader of each channel can be operated around
0dB. (See page 98.)
■ AUX
Stands for “auxiliary.” These are alternate signal output
destinations used to feed the two internal effects of the
01X or an external effect processor.
■ Buses
A signal route that mixes the signals from multiple chan-
nels and send them to an output jack or internal effect input
is called a “bus.”
Unlike channels, which handle only a single signal, a bus
can combine multiple signals into one or two, and send
them to a destination. (This comes from the common
meaning of the word, a vehicle to carry many passengers
simultaneously.) The 01X’s mixer section lets you use the
following buses.
● Stereo buses L/R
This mixes the input signals to stereo, and sends them
via the stereo output channel to the rear panel jacks (for
example, STEREO/AUX OUT/mLAN) as selected by
Output Patch.
● AUX buses 1 through 4
These combine the signals from the channel inputs, ste-
reo input and mLAN inputs, and send them to the rear
panel jacks (for example, STEREO/AUX OUT/mLAN)
as selected by Output Patch. AUX bus 3/4 can be also
used to input the signals to built-in effects 1 and 2.
● REC bus L/R
These combine the signals from the channel inputs, ste-
reo input and mLAN inputs, and send them via the REC
bus output channel to the rear panel jacks (for example,
STEREO/AUX OUT/mLAN) as selected by Output
Patch.
■ Channel
A signal routing unit through which a sound that is input to
the mixer section is adjusted by volume and pan and then
output. The mixer section of the 01X provides a total of 28
channels including the Stereo Inputs for the outputs of the
two effects.
■ Jitter
When digital audio signals are transferred, the wordclock
(page 23) of the devices must match. If this wordclock is
not generated accurately, a type of noise called jitter will
occur. Less variation in the wordclock rate compared to a
perfectly accurate square wave (i.e., a more stable clock)
will mean less jitter and better audio quality.
■ Library
This is a memory location for storing individual settings,
such as those of Scene, EQ or Dynamics. The 01X has
separate Libraries for Scene, EQ, Dynamics, effects, chan-
nels, input patch and output patch. Each Library is stored
(saved) to internal memory. The 01X also includes many
convenient presets in the Libraries for instant use in differ-
ent recording and mixing applications.
■ Nominal level
The “nominal level” referred to on a mixer or recorder
indicates the standard level setting for that device. When
all parameters are set to the nominal level, the audio qual-
ity will be the closest to the specifications given in the cat-
alog.
■ Scenes
A “Scene” is a program containing mixing settings and
internal effect parameter settings for all channels, and is
stored to internal memory in the Scene Library.
