5.5 ADJUSTING INPUT SENSITIVITY
To reach a maximum noise-free dynamic headroom from each
individual head unit/amplifier/speaker combination, it is impor-
tant to set the respective input gain controls correctly. The input
level settings determine the actual signal-to-noise ratio, and they
are also responsible for obtaining the maximum distortion-free
SPL (sound pressure level) from your specific setup.
Turn-on your head-unit and set the volume control to approxi-
mately 3/4 of full volume, while playing a dynamic track from
a CD. Slowly increase the LEVEL adjustment control of the
channel pair to which your subwoofer system is connected to.
Turn up the (sub channel) level control knob until you can just
about hear distorted bass sounds. Now you reduce the volume
level of your head unit to a „normal“ listening level and „add“ all
the remaining channel pairs, by turning up the corresponding
level controls - aiming for a balanced sound with a slight em-
phasis in the bass range. All remaining channels, no matter if
this concerns rear mounted coaxials, component- or kickbass
systems installed in the front doors - must be balanced against
the main level setting of your subwoofer.
