MID GAIN:
The voltage gain of the midrange amlifier can be varied as well, however in a ±2 dB
range only. As the midrange is so crucial for neutral reproduction we limited the
range compared to the tweeter level control.
ROOM EQ - Adapting to room acoustics
A more detailed possibility to optimize the reproduction are the two shelve filters
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 five curves, the controls can be changed continuosly, however.
ROOM EQ (shelve filter) for the low frequencies:
ROOM EQ (shelve filter) for the high frequencies:
