HIGH GAIN
The voltage gain of the tweeter amplifi er and thus the complete tweeter level can
be varied in a ±4 dB range. This is a considerable change in the sound characteristic
and should be used with caution. If there is a considerably damped room or if there
is a special taste you are after this control will serve you well.
ROOM EQ - Adapting to room acoustics
A more detailed possibility to optimize the reproduction are the two shelve fi lters
at both ends of the frequency band. Above - or below - the given cut off frequency
the amplitude is progressively changed. The given dB values occur at 20 Hz and
20 kHz. We show fi ve curves, the controls can be changed continuosly however.
