Driver gains
Whereas the 'Input Gain' raises or lowers the overall input sensitivity up to
+/-10 dB, the 'Driver Gains' work only within the corresponding frequency
range, raising or lowering from +/-2 to +/-6 dB.
4.5
High / low shelving
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 work differently. They 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).

frequencies above 6 kHz

Bass EQ Section (parametric EQ)
There are three fully parametric EQs (20 Hz to 200 Hz) that
can be used to combat standing waves in the control room.
The EQs can be bypassed individually or as a group so that
their overall effect can be analyzed in direct comparison to
the unaffected signal.

LED Dim
All LED indicators can be dimmed if necessary by pressing the 'LED Dim'-
button.
