Before replacing the fuse, power off
the audio source and then
disconnect the battery.
Remove the blown fuse and replace
it with the same model and rating
(same maximum amp)
FASTENING HOLES
Use the screws provided in the package
or screws of 4mm diameter. Tighten bolts
to a maximum of 5 Nm torque.
NEGATIVE POWER
CONNETION
Securely connect the
clamp to a metallic part
of the frame or chassis
of the vehicle. Strip the
paint and debris, and
use the shortest
possible cable with the
proper terminal.
POSITIVE POWER
CONNECTION
Connect the clamp to
the positive lead of the
battery. Use the
shortest possible cable
with the proper
terminal. We
recommend using an
external fuse as close
as possible to the
battery.
LOW PASS FILTER
Activate
Control
the low pass filter by pushing
the button
the cut-off frequency of the low-
pass filter by using the
potentiometer (knob)
ATTENTION!
Use power cables with a gauge that is appropriate to the
current load and to the length of the cable. The table in this
manual indicates the minimum gauge for safe use. Whenever
possible, use the largest gauge available.
