Cable Preparation; The Crossover - Rainbow SL-C3.2 Einbauanleitung

Detaching the protection grill
The protection grill can be detached for optical or sound quality
reasons by a spiky tool. Painting of the protection grill in individual
color is possible.
When putting back the protection grill on the tweeter there is no need
to glue it. The magnetic force of the tweeter's inside neodymium
magnet disc will fix the protection grill to the tweeter.
ATTENTION: Do not damage the tweeter cone with the spiky tool
and do not press into the cone.
Shorten tweeter cable (at least 1 mm²) to the appropriate length and strip both ends. Insert the red
conduit cover (+) over the appropriately marked conductor and the black cover (-) over the remaining
conductor. Solder one end of the stripped conductor to the u-shaped metal jacket. Provide suitable
polarity plug contacts at the other end of the cable as well as at the short connection cables of the
tweeters.
Note: Attach tweeter only over the prepared connection cables, preferably with suitable plug
contacts. Soldering of the cables directly to the tweeter is not possible. The tweeter can be
severely damaged by the soldering procedure.
Shorten woofer cable (at least 2.5 mm²) to the necessary length to run from the woofer to the screw
connections of the crossover and strip at both ends. Insert the red conduit cover (+) over the
appropriately marked conductor and the black cover (-) over the remaining conductor. Equip both ends
of cables with conduit covers provided and solder to the u-shaped metal jacket.
Note: If cables with a larger diameter than 2.5 mm² are being used for the installation, they must be
provided with the appropriate u-shaped metal jackets according to DIN 46244. Cables should
not be soldered at the screw connections. The heat from soldering causes the screw
connections to move out of position, making misfires caused by poor contact unavoidable.
In general, the loudspeaker cables should be kept as short as possible and run in such a way that they
are kept separate from the auto's electrical system, thereby preventing distortion from the generator and
electrical wiring. The loudspeaker cables can also be twisted together to help prevent distortion. Rolling
up excess loudspeaker cable length is not helpful, as it merely increases chances of distortion.
The tweeter range has been provided with a thermal protection device (PTC) in the crossover. This
added measure protects the high-quality tweeter against overly high performance levels. However, with
extremely high performance levels, the thermal protection device will shut down the tweeter to a low
level. Once reduced the power to a normal level the thermal protection device will cool down and will
release tweeter from protection status after a few minutes.
With SL-C6.2 Pro system, the tweeter range has been provided with a second thermal protection device
in the crossover additionally. This added measure protects the high-quality tweeter against overly high
performance levels. However, with extremely high performance levels, the protecting halogen bulb
(12V/20W/G4) can burn out and must then be replaced with a halogen bulb of the same type. If this
happens, remove crossover covers carefully and loosen the screws on the bulb mounting plate. Replace
the defective halogen bulb and firmly tighten screws again.
