LOUDSPEAKER WIRES
For longer distances to the speakers, it is best to use 1.5 mm² or 2.5 mm² speaker cables
to avoid a loss of power or risk degradation of the signal quality.
Once the speaker cables have been routed, connect them to the dedicated connector.
Maintain correct polarity („+“ to „+“; „-„ to „-„).
Close the electrical circuit by attaching the ground wire to the battery and switch on your
head unit. The green status LED should turn on. If the status LED does not illuminate or
the red protect LED lights up, your installation is wrong! Immediately turn off your head-
unit and carefully re-check all installation and wiring steps!
SELECTING THE OPERATION MODE FOR CH5/6 AND CH7/8
You must select and set the appropriate operation mode before you turn on the amplifier.
This operation mode depends on the speaker system connected to the respective ampli-
fier channels.
→ Select 4 ohm, if the speaker system has a single 4 ohm voice coil. If the speaker
provides 2 x 2 ohm voice coil, you need to connect both voice coils in series to get a 4
ohm load.
→ Select 2 ohm, if the speaker system has a single 2 ohm voice coil. If the speaker
provides 2 x 4 ohm double voice coil, you need to connect both voice coils in parallel
to get a 2 ohm load.
→ Select "BTL" if you want to drive the speaker in bridged mode. For BTL mode only 4
ohm load is workable. If you want to use BTL mode, then use CH5+ and CH6- for CH5
CH6 BTL mode and CH7+ and CH8- for CH7 CH8 BTL mode.
