REDUCING THE TREBLE BY 1DB
KEILIDH LS 300 :
PROCEDURE ON HOW TO REDUCE THE
TREBLE BY 1 dB
This procedure is the similar for KEILIDH, TUKAN, CENTRIK. The SEKRIT procedure
is also similar once you gain access to the crossover, see 6.18 on removing the
baffle. All crossovers also have instructions on them describing the required steps.
TOOLS REQUIRED:
2.5 MM Allen key (Hex key)
Small pair side cutters.
Silicone sealer and dispenser. ( Where required, see 2 below)
Temperature controlled Soldering Iron and Multicore solder.
PROCEDURE
1.
Place one speaker on its back and carefully remove the bass unit trim rings.
2.
Remove the silicone that may be between the unit and the cabinet. This is best
done by rubbing it off with your finger. Be careful not to damage the surround
of the unit.
Please note: Later cabinets do not use silicone, trim ring is held in place by
locating in a groove in the baffle
3.
Remove the 4 bolts that secure the bass unit to the cabinet
4.
Lift the unit out of the cabinet and un-solder* the wires from the crossover.
Place carefully to one side. *Alternative is to leave it soldered but support the
unit when you move the speaker, to avoid cabinet or unit damage.
5.
Stand speaker upright and remove the collars from the back of the speaker.
KEILIDH: Do not loose the 2 blanking discs from the Aktiv bass sockets.
6.
Remove the wadding from the speaker and lift the crossover off the back of the
speaker.
7.
Locate resistor normally R1(see board)
on the crossover.
Cut and lift one leg of resistor clear from
board, bending it back to ensure that it
cannot short. Do not cut both in case you
wish to connect it back. KEILIDH NOTE:
Speakers over serial number 21,000 will
have the resistor located on the left side
of the board.
8.
Replace the crossover on to the back
panel and secure in place using the
speaker socket collars. Make sure that
the treble input is at the top!
9
Replace the wadding then solder (if
required, see 4 above) the wires back on
to the bass unit terminals, red wire to red terminal. Refit the gasket and screw
the unit in place. Repeat whole procedure with other speaker.
10.
Now carry out listening test and if satisfied with the result secure the trim ring
back in place with silicone (where required, see 2). Caution: Use silicone
sparingly and avoid getting it on to the surround of the unit.
