Cadence M7000 Car Amplifier User Manual


 
Thermal Protection: When the amplifier reaches an unsafe operating
temperature of 80 degrees Celsius the amplifier will turn off. Once the
amplifier cools down, simply reset the amplifier by its Remote
connection,(turn the amplifier off and then of again once you have given
the amplifier a chance to cool down) and the amp will once again begin to
play.
If you live in hot climate we suggest installing additional cooling fans in
your trunk to exhaust the hot air which can build up in the trunk this will
help keep the ambient temperature in the trunk as low as possible so that
your amps work flawlessly and without any musical interruption.
Speaker Short Circuit Protection: Should your speakers short circuit
due to voice coil burn out, or should the amplifier sense an impedance
too low to handle, the Protection LED will light, indicating a diagnostic
condition. Turn off your system, disconnect one speaker at a time and try
to determine which speaker might be faulty. Correct the condition and
restart the amplifier. You must reset the amplifiers by turning off and then
on by the Remote power for proper operation after correcting a
diagnostic condition.
Clipping or total shutdown may also be a result of a bad ground
connection or loose ground. If you find that your speakers and speaker
wires are not shorted, please check your ground connection.
Input Overload Protection: This circuit will either shutdown the
amplifier completely or make the amplifier spurt on and off indicating
that it is in a diagnostic condition. Turn the system off and reduce the gain
on the amplifier or volume from your head unit, this should result in a
corrected condition.
DC Offset Protection: Should any DC voltage try to enter the amplifier via
the speaker terminals it will cause the amplifier to shut down and not
operate until this condition is remedied. This circuit will also protect
damaging high DC voltages from reaching your speakers should you
amplifier ever miss-function.
INSTALLATION BASICS
Before you begin with your installation disconnect the NEGATIVE (-)
terminal from your car's battery. This safety precaution will avoid possible
short circuits while wiring your amplifier. Cadence amplifiers operate on
12-volt negative ground system only.
