Input and Output Notes
The Rockford Fosgate Punch P600.1 bd amplifier features a removable terminal
cover. It conceals all speaker, signal, remote, power, and ground connections,
as well as the gain and crossover frequency controls for a cleaner installation.
Aluminum Heatsink: The Focused Mass 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
INDIGO (INDexed Ideal Gain
Operation): The INDIGO PWM
(pulse width modulation) power supply is designed to make the most of the
situation it is presented with. When battery voltage is low, you are guaranteed
to get the power you paid for. When voltage increases, the amp makes even more
(Maximum 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
eliminates noise. The TOPAZ circuit prevents ground loops by allowing the output
impedance of the source unit to determine the signal ground impedance the amp
sees. This virtually assures that the signal ground out of the head unit and the
signal input ground of the amplifier are identical, eliminating any chance for a
ground loop. The result is a 30-40dB improvement of the isolation between input
ground and chassis ground.
Trans-ANA (TRANSconductance Active Nodal Amplifier): The
trans-ANA is a circuit that allows the audio signal to pass through the
amplifier at low voltage. The signal is directly level-shifted to the fixed high
voltage rails via a pair of drive transistors. Signal linearity is assured by an
active node formed by the drive transistors at ultrasonic frequencies. The
result is crystal clear sound quality.
(NOn-Multiplying Advanced Decision): 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 P600.1
bd 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.
Internal Filter: The
amplifier's internal 12 dB per octave Butterworth low-pass filter is variable
from 35 to 250 Hz.
Infrasonic Filter: The
infrasonic filter allows the amplifier to block ultra-low frequencies that your
subs can't reproduce, improving the efficiency of your speaker system. The
filter is fixed at 28 Hz, and has a slope of 12 dB per octave. You can turn the
filter on or off.
Remote Punch Bass: The Punch
Bass helps correct for acoustical deficiencies in the listening environment by
helping reproduce full range sound without adding excessive boost. The Punch
Bass control has a narrow band adjustment centered at 45Hz, variable from 0dB to
+18dB. The supplied Punch Bass wired remote can be mounted in a variety of
locations. The module's case can be removed and positioned with the mounting
bracket above or below the module. Without the case the module can be flush
mounted in your vehicle's dash (requires a 2" x 7/8" cutout with a maximum panel
thickness of 3/8"). The wired remote is 2.294" wide, 1.293" tall and 1.509" deep
(2.606" including the knob and cable connection). The included cable is 16.25'
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
LEDs: There are three LEDs on the top of the amplifier. A blue Power LED
illuminates when the unit is turned on. A yellow Protect LED illuminates if a
short circuit or too low an impedance is detected at the speaker connections. A
red Thermal LED illuminates if the amplifier overheats. The amplifier will
automatically shut down if either the yellow or red LED indicates amplifier
Input and Output 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
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.
Note: Although there
are two sets of speaker terminals, the amplifier still produces a
monaural signal. The A and B speaker outputs are internally wired in
Remote Punch Bass Connection:
An RJ-45 jack is provided for connecting the supplied Remote Punch Bass cable.
CEA-2006 Compliance: The
specifications given by Rockford Fosgate for the Punch P600.1 bd amplifier
comply with the new 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.
Certificate: Each amplifier comes with a Performance Verification
Certificate which lists the results of a 10-point performance inspection as well
as a measurement of the actual power output of that amp.
A one year warranty extension, for a total of two years, is provided by Rockford
Fosgate when this amp is wired using a qualifying Rockford Fosgate amplifier
wiring kit. Qualifying wiring kits include CP4POS and CP4CKDS.
