“ARVA” - AUTOMATIC RAIL VOLTAGE ADJUSTMENT
CIRCUITRY:
Rockville RX Phenom 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. Rockville RX Phenom
Series amplifiers have tighter sounding bass reproduction thanks to this unique circuitry.
BATTERY VOLTAGE:
Rockville RX Phenom 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. ***
Though capable of high power reproduction, Rockville RX Phenom Series amplifiers are not
competition style amplifiers! They were designed for audiophile sound reproduction.
PROTECTION CIRCUITRY:
Rockville amplifiers incorporate many outstanding protection circuits to help protect the amplifier
from being damaged during operating conditions.
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.
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.
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 it OFF and
then ON again by the Remote power connection after correcting a diagnostic condition. (Turn your radio off
and then on again.)
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 malfunction.
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. Rockville 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 heat sink 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.
