Glossary

 – Dithering is a mathematical process where a random noise is 

added to the least significant bit of a digital word. With very low level 
signals, the quantization error becomes correlated to the signal level. This 
creates a measurable amount of distortion. By adding dither, the correlation 
between the signal level and the quantization error is cancelled, allowing 
the digital system to encode amplitudes smaller than the least significant 
bit. If you change the word size as a signal passes from one digital system 
to another, being able to add dither allows you to maintain a high quality 
signal.

 – A specialized circuit, usually a chip, that 

is designed to manipulate large quantities of data in real-time. YAMAHA 
has developed world renowned expertise in proprietary musical 
application specific digital signal processing.

 – Ducking is used to automatically reduce signal levels when the 

level of a source signal exceeds a specified threshold. It is used for 
voice-over applications where, for example, level of background music is 
automatically reduced, allowing an announcer to be heard clearly. See 
Dynamics Processor.

 – The difference between the loudest (maximum output 

level) and quietest (residual noise floor) sounds produced in an audio 
system. The dynamic range in a digital system is determined by the data 
resolution, about 6dB per digital bit. A 20-bit system has a theoretical 
dynamic range of 120 dB. The 02R has a specified dynamic range of 105 dB.

 – An area in 02R memory used to access and store 

dynamics settings – stored as programs. There are 40 preset programs (1 to 
40) for you to recall and 88 user programs (41 to 128) for you to store your 
own dynamics settings.

 – Dynamics processors are used to correct or control 

signal levels. The 02R features comprehensive dynamics processors for all 
the input channels, tape returns, and the bus and stereo outputs. These 
processors allow you to compress, expand, compress-expand (compand), 
gate, or duck the signals passing through the mixer. See Compander, 
Compressor, Ducking, Expander, and Gate.

 – The Edit Buffer is the current mix settings. When a scene 

memory is recalled, the mix settings of the selected scene memory are 
written to the Edit Buffer. When a scene memory is stored, the mix settings 
in the Edit Buffer are written to the selected scene memory.

 – The 02R is equipped with a four-band, fully parametric 

equalizer, with variable bandwidth (Q), center frequency (F), gain (G), and 
ON/OFF parameters. equalization can be applied to the input channels, 
the tape and effect return channels, and the stereo output. For stereo 
channels, the equalization curve is applied equally to both channels.

 – An area in 02R memory used to access and store 

equalizer settings – stored as programs. There are 40 preset programs (1 to 
40) for you to recall and 88 user programs (41 to 128) for you to store your 
own equalizer settings.
