Inputs and Outputs Notes
Rockford Fosgate Punch RF2002 amplifier features dual removable covers.
One of the covers conceals all speaker, signal, remote, power and ground
connections, as well as the gain and crossover frequency controls for a clean
Aluminum Heatsink: The cast aluminum heatsink dissipates heat
generated by the amplifier's circuitry. The inherent advantage of casting
provides a 30% improvement of cooling over conventional extrusion heatsink
Efficiency Heat Sink Application):
MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer
from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA
substrate operates with minimal thermal resistance, spreading heat both downward
and outward to quickly dissipate heat from each device across the heatsink. This
allows greater power output, enhanced thermal stability, and maximum
(Tracking Operation Pre-Amplifier Zone):
TOPAZ is a circuit that simply eliminates noise. The TOPAZ circuit allows the
amplifier ground to move with the source unit ground, creating a "noise
elimination" zone just before the preamp section. If there is any noise in
the ground coming down the RCA line to the amplifier, TOPAZ amazingly tracks it
down and eliminates it. The result is a 30-40dB improvement of the isolation
between input ground and chassis ground.
NOMAD is an intelligent protection circuit that uses an analog computer to make
real time decisions regarding temperature, voltage, current and impedance. The
unit is protected without limiting sound output unless needed.
(Discrete Surface Mount):
In the manufacturing process high speed robotics are used to place 0% tolerance
resistors and large board traces providing greater reliability and efficiency.
TO-247 MOSFET: The Punch RF2002
utilizes ultra high performance MOSFET output devices, giving the amplifier more
power handling capability as well as lower thermal impedance for more reliable
operation, even under the harshest load conditions.
The amplifier's internal front and rear crossovers are 12dB/octave Butterworth filters, independently selectable for
high-pass, all-pass (full range) or low-pass operation variable from 40Hz to
Optional Remote Punch Bass:
The amp has an input for the optional Remote Punch Bass control, which boosts
low frequency information to overcome road noise. The Punch Bass control would
provide a narrow band adjustment centered at 45Hz,
variable from 0dB to +18dB.
RCA Pass-Thru Jacks:
The pass-thru jacks provide a convenient source for daisy-chaining an additional
amplifier without running an extra set of RCA cables from the front of the
vehicle to the amplifier location. The pass-thru jacks output a full-range
Power Indicator and Protection LED:
The red LED beside the RF logo, located on the top left of the amplifier,
illuminates when the unit is turned on. The LED will go out if the amplifier
overheats. The amplifier will automatically shut down to cool if this occurs. In
Protect Mode, the LED will blink slowly if a short circuit or too low of an impedance is detected at
the speaker connections. The amplifier will automatically shut down if this
and Outputs Notes
Power Connections: The power
and ground terminals are nickel-plated captive c-clamp wire connectors and will
accommodate up to 4-gauge wire. The remote turn-on terminal will accept wire
sizes of 12- to 24-gauge. A Phillips-head or slotted screwdriver (not supplied)
is required to tighten/loosen the terminals.
Speaker Connections: The
2-channel nickel-plated clamp wire connectors will accept wire sizes of 8- to
18-gauge. A Phillips-head or slotted screwdriver (not supplied) is required to
tighten/loosen the terminals.
Remote Punch Bass Connection: An
RJ-45 jack is provided for connecting the optional Remote Punch Bass cable.
CEA-2006 Compliance: The
specifications given by Rockford Fosgate for the Punch RF2002 amplifier comply
with the CEA-2006 Amplifier Power Standard from the CEA (Consumer
Electronics Association). All manufacturers who comply with the standard can
display the CEA-2006 logo on their product.
