■ 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.

●

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.

●

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.

●

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.
