Protection circuitry
The built-in protection circuitry in the pyramid
Arctic amplifiers will disable the amplifier if it
senses an input overload, a speaker short
circuit, or extreme temperature conditions.
If this occurs ,carefully inspect the system to
determine the source of the problem.
When the protection circuit is activated by any
of these conditions,
the Protection LED will be
illuminated.
If the shutdown was a result of a thermal overload
condition, allow the amplifier to cool down before
attempting to restart it.
If the shutdown was a result of an input overload,
or speaker short circuit, be sure to corr the
condition before restarting.
The amplifier
can be restarted by turning the
remote power OFF and then ON again.
No output.
Check both in-line and built-in fuses. Both the +12V and the Remote terminals
must have +12V referenced to chassis ground.
Confirm that all terminal strip connections are secure and tight.
Confirm that the audio signal source(car radio, equalizer, etc.) Is connected
and is supplying output signal. To check if the
amp is supplying signal, unplug
the cables from the signal source(but leave them plugged into the amp).
Briefly tap the center pin of each of the disconnected RCA plugs with your finger.
This should produce a noise)feedback) in your speakers.
Only one channel works.
Confirm that all terminal strip connections are secure
and tight.
If the above steps fail to improve or clear noise interference, the system
should be checked by a professional mobile audio installer.
If you are using the Low Level RCA input , reverse the input plugs at the
amplifier(i.e.,switch the L with the R). If the channels which is
silent switches
to the other side, the problem is either in the head unit/other source or the
connecting cables.
Weak output.
If the noise is a “clicking” or “popping” noise whose rate follows the engine
speed, this usually means that the vehicle is equipped with resistor spark
plugs and wires, or that
the ignition is in need of service.
Noise in the audio.
Readjust the Input Level Control(s) to better suit the input signal.
If the noise is a “whine” whose pitch follows the engine speed, confirm that
the amplifier and any other signal sources(hesd unit, etc.) Are properly ground.
Check the Balance control
on the head unit(or other source) to verify that it
is set to its midpoint.
Check the routing of the speaker and input wires to make sure they are not
adjacent to wire which interconnect lights and other accessories.
