Input Gain; High Gain; High & Low Shelfe Filter - Adam S1X Bedienungsanleitung

4.3

Input Gain

'Input Gain' regulates the overall input sensitivity of
your loudspeaker within a range of -10 to +10 dB, and
controls the volume of your loudspeaker equally in all
frequency ranges.
4.4

High Gain

Whereas the 'Input Gain' raises or lowers the overall in-
put sensitivity up to +/-10 dB, the 'Tweeter Gain' works
within the frequency range of the tweeter (>1.800 Hz)
only, raising or lowering up to +/-4 dB.
This is a considerable change of the sound characteristic
and should be used with caution. However, to meet difficult room acoustics
or adapt to a special taste the Tweeter Gain will serve you well.
4.5 High / Low shelf filter (Room EQs)
The other two controls operate in a different manner.
The 'High Shelve' is a shelving filter that progressively
raises or lowers above 6 kHz up to 6 dB. Whereas the
gains raise or lower a specific frequency range as a
whole, the shelve filters do not alter a whole frequency
band but alter in this band: from a certain point (6 kHz
respectively 150 Hz in this case) the frequencies are
gradually being changed (see figure 5 & 6).
