Utility functions 

Three utility functions are provided to adjust screen contrast, the display units used for 

parametric equalisation bandwidth and switch between stereo and mono mode. 

The device automatically adjusts for the variations in display contrast as the temperature of 

the LCD changes. The screen contrast utility control sets the base contrast of the screen 

and also allows optimization for a given viewing angle. 

Parametric equalisation width parameters can be displayed in either ‘Q’ or bandwidth, 

expressed in octaves.

Care should be taken when swapping between mono and stereo mode as the parameter set 

for the left hand channels will be copied to the right hand side, overwriting those settings. 

This is not reversible and could represent quite a significant and potentially damaging 

change to the processing.
