MAIN POWER CABLE ROUTING
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 fire hazards, resulting from a
short-circuit of the main power cable to chassis ground an ANL fuse holder must be inserted within the
first 30cm of the positive main power cable. The applicable fuse value must be matched to the limita-
tions of your main power cable AND the current draw of the amplifier – therefore choose an appro-
priate fuse value.
Attach the ground cable to the amplifier. Try to keep the ground cable („-12V“) as short as possible,
i.e. to find a chassis contact very close to the amplifier. The ground power cable must have the same
cross-section as the positive power cable. The contact surface point on the car chassis must be solid
and clean, i.e. free from rust or paint!
Tighten both power input terminals of the amplifier, and double check for perfect fit.
7. ADJUSTMENT OF THE CONTROL FUNCTIONS
SELECTING THE OPERATION MODE FOR SATELLITE SPEAKERS
Before you power up your amplifier, you must select and set an appropriate operation mode first. The
OPERATION MODE is set, depending on the speaker system connected to the amplifier.
You must configure each stereo channel pair to work in either in fullrange, highpass, lowpass or even
bandpass mode. Select the appropriate operation mode for each channel pair, for example select
HIGHPASS, if the speaker system is a component-, coaxial- or triaxial- type, or BANDPASS in case of
a kickbass system, or LOWPASS if the channel pair will drive a subwoofer system respectively. If you
own a head-unit, that features an integrated DSP controlled active crossover, it is recommended to use
the DSP based crossovers – in this case you need to set the operation mode slide switch(es) to
FULL(range)!
In all other cases you MUST set the OPERATION MODE of each channel pair to the corresponding
HP,LP or BP setting, that corresponds to the function of the connected speaker pair! Otherwise, your
speaker system(s) might be damaged!
SELECTING A CROSSOVER FREQUENCY POINT FOR SATELLITE SPEAKERS
For satellite speakers, you must select the position “HP” on the OPERATION MODE switch. The “HP”
operation mode will take away unnecessary mechanical and electrical ‘strain’ from the connected coa-
xial or component speaker system. Depending on the actual cone surface, voice-coil diameter and the
rated power handling of the installed ‘satellite’ speakers, it is recommended to set the high-pass cross-
over frequency point between 50 and 150Hz, using the „HI PASS“ frequency control.
Note, that the appropriate setting should always be determined by ear!
