The Front Panel
The Front Panel Controls allow the speaker to be adapted to different listening and
room requirements. There are controls for:
INPUT GAIN
(Input sensitivity) ±10 dB, 0 dB for medium sensitivity
HIGH GAIN
(Tweeter gain) ±4 dB, 0 dB for flat response
MID GAIN
(Midrange gain) ±2 dB, 0 dB for flat response
Room EQ >6 kHz
Shelve Filter with 6 kHz cut off frequency
Room EQ <150 Hz
Shelve Filter with 150 Hz cut off frequency
INPUT GAIN:
To adapt to different signal levels, the voltage that is needed
to drive the unit to its maximum SPL (sound pressure level), is
variable in a ±10 dB range.
The voltage gain of the tweeter amplifier and thus the complete tweeter level can
be varied in a ±4 dB range. This can cause 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.
