Cadence Q Series amplifiers feature "ARVA" circuitry in their power supply. This circuit
constantly monitors the output stage and under high current demands will adjust the power
supply rail voltages so that enough power is available for peak situations. The "ARVA" also
improves the damping factor of the amplifier when playing low impedance mono loads.
Cadence Q Series amplifiers have tighter sounding bass reproduction thanks to this unique
circuitry.
CadenceQ Series amplifiers are rated and regulated to 13.8 volts and below. Increasing
voltage to 14.4 volts will increase the power output of the amplifier in the same proportion.
Maximum input voltage is 14.4 volts while the minimum voltage is 12 volts.
DO NOT EXCEED 14.4 INPUT VOLTAGE.
Cadence Q Series amplifiers are not competition style amplifiers!
Cadence amplifiers incorporate many outstanding protection circuits to help protect the
amplifier from being damaged during operating conditions.
If you live in a 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.
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 on again once you have
given the amplifier a chance to cool down) and the amp will once again begin to play.
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 amplifier 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 your amplifier ever miss-function.
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 systems only.
It is recommend that you layout your sound system design on paper first. This will help you
during the installation so that you will have a wiring flow chart and not miss-wire any of your
components.
Mount the amplifier in the trunk or hatch area of your vehicle. Never install an amplifier in the
engine compartment or on the firewall. Please be sure to leave breathing room around the
amplifier heatsink so that it can dissipate the heat it produces efficiently. The amplifier can be
installed either horizontally or vertically.
When mounting the amplifier on the trunk floor, be sure to watch for your gas tank, gas lines
and electrical lines. Do not drill or mount any screws where they might penetrate the gas tank
of your car.
