Philosophy Of The Crossover; Connecting The Crossover - Rainbow SL-C3.2 Einbauanleitung

For audiophiles the halogen bulb can be replaced by a silver wire jumper.
Note: The overload protection of the tweeter will thereby be lost. Therefore care should be taken in
adjusting the volume control!
Experimentation is highly encouraged!
The crossovers are designed in such a way that a multitude of sound combinations is possible, allowing
listeners to select their personal preference. Because each person hears differently and each vehicle
possesses different acoustics, we can give only basic positioning recommendations here. Therefore,
experimentation incorporating individual preferences is encouraged! Normally high and middle range
tones sound louder on the driver's side, since the driver sits directly in the sound field of the
loudspeakers. The front passenger side is comparatively quieter, since the speakers are located farther
away, with timing delays even being detectable. The result is inevitably an unbalanced sound.
A basic correction of the sound can be achieved as follows: The crossovers of the front passenger side
can be adjusted through „frequency response". Note that the frequency of the crossovers on the driver's
side is adjusted until a pleasant, stress-free sound is achieved. Under normal conditions thereafter, high
and middle range tones are around at least 6 dB quieter than on the front passenger side. For optimal
positioning, a professional dealer, who can more accurately position the frequency response using
specific measuring instruments, should be contacted.
Note: It is important that all loudspeakers are correctly attached before start-up of the crossovers. If
the crossovers are set into operation without the loudspeakers being hooked up, a very high
current is produced on the unloaded LC-filters, which can, under the circumstances, destroy
the coils! The wire jumpers of the crossovers must always be placed on the specified pins,
according to the instructions. Other combinations are not functional and do not behave like
unattached loudspeakers! What's more, improper connection of the crossover will prevent it
from working within the intended range.
Connection of Amplifier/Radio:
Attach prepared loudspeaker cable (2.5 mm²) at the screw connections „Input" of the crossover, whereby
the connector with the red conduit cover is connected with the positive terminal and the connector with
the black conduit cover with the minus connection. Attach the other end of the loudspeaker cable making
sure the polarity corresponds with that on the amplifier and radio sides.
Connection of Woofer:
Attach prepared loudspeaker cable (2.5 mm²) at the screw connections „Woofer" of the crossover,
whereby the connector with the red conduit cover is connected with the positive terminal and the
connector with the black conduit cover with the minus connection. Attach the other end of the
loudspeaker cable, making sure the polarity (+/-) of the connections corresponds, and connect to the
woofers.
Connection of Tweeter:
Attach prepared loudspeaker cable (1 mm²) at the screw connections „Tweeter " of the crossover,
whereby the connector with the red conduit cover is connected with the positive terminal and the
connector with the black conduit cover with the minus connection. Connect the other end of the
loudspeaker cable, preferably with suitable contacts and making sure the polarity of the connections
correspond, to the available connection cable of the tweeters (+ = red marking)
