Cable Routing; Adjustment Of The Internal Crossover - Spectron SPA250Z Bedienungsanleitung

CABLE ROUTING

RCA INTERCONNECTS AND REMOTE WIRING
Run the RCA interconnects and the remote lead from the head-unit to the amplifier.
Note that RCA interconnects must be routed away as far as possible from the main
power cable. Connect the remote (turn on/off) lead to the REM input terminal of
the amplifier and to the remote output lead of your head-unit. Now you can plug in
the RCA interconnects to the line outputs of your head-unit and to the RCA inputs
of the amplifier. Pay attention to the channel identification of the RCA plugs ad
interconnect: left channel = white RCA, right channel = red RCA).
LOUDSPEAKER WIRE ROUTING
Strip the ends of the speaker wires and turn loose the speaker terminal screws. After
inserting the stripped speaker cables – re-tighten the screws. Be sure to maintain
correct polarity („+" to „+"; „−" to „−").
MAIN POWER CABLES
Run the positive main power cable („+12 V") directly from the positive terminal of the
car battery to the amplifier. For protection of your car audio system against electrical
short cuts and fire hazards, you must insert a main fuse holder within the first
30cm of the positive main power wire. The fuse value must be matched to the
current (A) limitation of your main power cable cross section and not to the amplifier
fuse rating!
Connect the ground wire to the ground terminal input (GND) of your amplifier and to
a grease and rust free ground point in your vehicle. Always try to keep the ground
wire („-12V") as short as possible. The ground power cable must have the same
cross-section as the positive power cable.
Tighten up both power input terminals, and double check for tight fit of both main
power wires!
Insert the main fuse, or reconnect the ground lead to the negative pole of your
battery.
If you power on the headunit, the LED of your SPECTRON amplifier should light up
green. If the LED lights up red, your wiring is wrong and you have to double-check
and verify all previously described installation steps again!

ADJUSTMENT OF THE INTERNAL CROSSOVER

OPERATION MODE
You must now select and set the appropriate operation mode of the electronic
crossover first. This setting depends on the speaker system connected to the
corresponding channel pair of the amplifier. For example, set the "XOVER" slide
switch to highpass (HI), if the speaker system driven by the corresponding channel
pair is a component-, coaxial- or triaxial- type. Or else, set the "XOVER" switch to
lowpass (LOW), if the corresponding channel pair is intended to drive a subwoofer
system.
Highpass or lowpass filtering allows the connected loudspeakers to work in the
frequency band they can reproduce best.
