4) GAIN CONTROL (± 6 dB)
a) The gain control can be used to adjust the input level of the amplifier module
by ± 6dB. It serves to balance the volume levels of the various systems. In or-
der to avoid overloading the input circuit or mixer's output circuit, it should
normally be set in the case of K&F full-range systems at 0 dB (centre notch
setting).
b) When operating with C2 Controller, set the input level of the amplifier mod-
ule on the C2 Controller (Input Gain). The gain control on the SP speaker
should be set at 0 dB (centre notch setting). One exception to this rule is a
cluster arrangement, in which the inner speakers should be set at a lower
level than the outer ones. In this case, the level of the gain control on the in-
ner SP speakers can be adjusted downwards accordingly.
When operating with additional bass systems it is very important that the respec-
tive volume levels between the top speakers and the bass systems are correctly
balanced. To this end, the sound engineer should check the volume levels during
the set-up and adjust them accordingly. When setting up a system without C2
Controller this adjustment should be carried out using the gain control of the SP
subwoofer; in the case of a system with C2 Controller, use the 'Sub Gain' control
on the C2 Controller.

* These details may vary due to different room geometries. The position of a bass
speaker is also crucial for its actual sound level. A bass speaker, which is on the
floor, can be a few decibels louder than a flown bass system because of the floor
reflections. Because of this, a sound engineer must always fine-tune the system us-
ing the corresponding level controls.
