DISPLAY
The display can be used to display the spectrum or the equalization level.
• For spectrum display (L), (R) or (L.R)
OB
+ 12 - · - ·
* The "full range" area on the right side
displays the combined level of all of the
frequency bands.
* If there is no input signal to this unit. The 1st
row (0 dB) of all frequency bands is
displayed.

AUTOMATIC LEVEL FUNCTION
This unit incorporates a function for automatic adjustment of over-indication or under-indication of the spectrum (caused by high or low
input signal levels), so that the displayed spectrum is always at the central part of the display for easy visibility.
• When input level is high
