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 K&F System Controller, set the input level of the ampli-
fier module on the 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 lev-
el than the outer ones. In this case, the level of the gain control on the inner
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 a K&F
System Controller this adjustment should be carried out using the gain control of
the SP subwoofer; in the case of a system with K&F System Controller, set the
gain on the 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.
