5. CROSSOVER SETTINGS
5.4 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 correspon-
ding level controls - aiming for a balanced sound with a slight
emphasis 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.
5.5 ADJUSTMENT OF PHASE SHIFT
CONTROL
The phase shift function of channels CH5/6 can be activated with
the corresponding slide switch. The phase-shift control enables
you to match the acoustical phase relations of subwoofer and
the speaker system playing in the front doors, either a component
or a kickbass system. The target is that both speaker systems,
normally separated by aprox. 3m of distance are intended to
play acoustically "in-phase" at the drivers seat location. A
good match of the acoustical phase between subwoofer and
the system in the front doors will give you the impression of
bass sounds coming from a place in front of you. Or the other
way round, the subwoofer playing in the trunk of your car can
not be localized that easily.
The second advantage is, that the upper bass region - i.e. where
the sound waves radiated by the subwoofer and the kickbass or
front door mounted component system are crossing over - will
sound considerably more precise and tight. This phase adjust-
ment can only be determined by ear, there is no rule of thumb
to find a good match, and you will definitely need somebody
to help you. To judge the effect of the phase-shift adjustment,
you must sit in the drivers seat, and somebody must adjust
the phase shift control knob until the sound reproduction in
the bass region is best. Furthermore, it might be necessary to
invert the (connection) polarity of your subwoofer - and re-adjust
the phase, if you can not find a proper match with the correct
polarity subwoofer in-phase connection.
