Cast 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 designs.
Dynamic Thermal Management (DTM):
DTM Evenly distributes excess heat across entire
(Maximum Efficiency Heat Sink Application-Third Generation): 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
Trans-ANA (TRANSconductance Active Nodal Amplifier): 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.
TO-247 MOSFET: The Power T500-1bd
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.
(Discrete Surface Mount): In the manufacturing process high speed
robotics are used to place 1% tolerance parts and large board traces. DSM
improves the efficiency of the circuit, decreases cross-talk from other discrete
components and lowers operating temperature.
Low Impedance: The T500-1bd is 1-ohm stable and outputs 500 watts RMS into a 1 ohm load.
Power and Protection LEDs: The LEDs are
located on top of the amplifier. A blue Power LED illuminates when the amplifier
is turned on. A red Thermal LED illuminates if the amplifier overheats. The yellow Protect LED illuminates if a short
circuit or too low an impedance is detected at the speaker connections. When any
of the protection circuits engage, the amp automatically shuts down until the
problem is corrected.
Internal Crossover: The
amplifier's internal crossover has a 24 dB/octave slope. The crossover point is variable from
35Hz to 250Hz.
Punch EQ: Punch EQ acts as a variable bass boost; 0-18 dB at 45 Hz.
Infrasonic Filter: The infrasonic high pass filter is designed to prevent frequencies below the
audible range from being applied to the subwoofer from the amplifier,
consequently improving subwoofer performance and power handling, particularly in
vented enclosures. The crossover point is fixed at 28 Hz, the slope is 12
dB/octave, and the filter can be turned on or off to suit your preference.
Power Connections: The power
and ground terminals are nickel-plated captive c-clamp wire connectors and will
accommodate up to 4-gauge wire. An external 100-amp fuse (not included) must be
installed on the power 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
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 parallel.
Line Input/Output: The RCA jacks are
nickel plated to prevent corrosion. The full range line output allows easily
adding another amp without running a second set of cables.
Remote Punch EQ (PEQ) Connection: An RJ-45 jack is provided for connecting an optional remote PEQ control (item
number 575ROCKPEQ). If you use the remote PEQ, the Punch EQ control on the
amp is disabled, and replaced by the remote.
Previous model Punch Bass and Para-Punch remotes will not work with this amp.
