DC-FEED DLS A4
If you use both DC-inputs for the DC feed,
connect a Fuse block with two 70 Amp fuses, one
for each input.
If you have problems
with the mid bass dri-
ver ”reaching the bot-
tom” (the voice coil
touches the bottom
pole plate) at high
volumes, use the HP-
filter to avoid this with
a setting at 50 - 80 Hz
or higher. Make your
own tests.
Use a 2 mm hexagon key to speaker terminals.
Use a 2,5 mm hexagon key to DC input terminals on A1
Use a 4 mm hexagon key to DC input terminals on A2, A3, A4
