| Rockford Fosgate - Type RF Series
Envisioned as an engineering test bed, the Type RF amplifier platform provides
Rockford Fosgate engineers with the perfect vehicle to explore cutting edge
technologies. Programmable DSP functions, 4 stage thermal management and
extensive audio signal manipulation all made their debut in Type RF amplifiers.
A stunning cosmetic package built on a revolutionary chassis; the Type RF
amplifier introduced the mobile electronics industry to the concept of “focused
mass” thermal management. Creative use of heatsink material, space age plastics
and audiophile components created an award-winning design that allowed for
large, clean, transparent power output in a sleek, stylish package. Three years
after it changed the way people think about mobile amplifiers, Type RF is still
ahead of the curve.
Design Features:
- Variable Crossover – The amplifiers have a built-in 24dB/octave
Butterworth filter with a crossover point variable from 40Hz to 250Hz. The
crossover is set to Low-Pass (LP).
- Protect LED – The (red) LED illuminates when the unit is latched
into protection. It requires momentary AP removal to enable output PWM.
- Gain Control – The input gain control is preset to match the output
of most source units. It can be adjusted to match output levels from a variety
of source units.
- Phase – Used when connecting two bd amplifiers together to phase
one amplifier 180° from the other.
- Infrasonic Filter – A high pass filter designed to prevent
frequencies below the audio range from being applied to the subwoofer from the
amplifier. Consequently, improving subwoofer performance and power handling.
- LED Power Indicator – The LED illuminates when the unit is turned
on.
- Cast Aluminum Heatsink – The cast aluminum heatsink of the
amplifier dissipates heat generated by the amplifier's circuitry. The inherent
advantage of casting provides a 30% improvement of cooling over conventional
extrusion heatsink designs.
- Sync – These amplifiers have a 6 pin mini DIN connector. When
operating two amplifiers in the bridge mode, the SYNC cable must be used. This
will allow the two independent frequency carrier generators in each unit to be
synchronized.
- Speaker Terminals – The heavy duty, gold-plated terminal block
connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG. These
gold-plated connectors are immune to corrosion that can cause signal
deterioration.
- Power Terminals – The power and ground connectors on the amplifier
are gold-plated and will accommodate up to 4 AWG wire maximizing the input
current capability of the amplifier.
- REM Terminal – This terminal is used to remotely turn-on and
turn-off the amplifier when +12V DC is applied.
- RCA Input Jacks – The industry standard RCA jacks provide an easy
connection for signal level input. They are gold-plated to resist the signal
degradation caused by corrosion.
- RCA Pass-Thru Jacks – The Pass-Thru provides 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 rear amplifier location.
- Punch Bass – The Punch Bass control helps correct for acoustical
deficiencies in the listening environment by helping produce full range sound
without adding excessive boost.. The Punch Bass control is a narrow band
adjustment at 45Hz variable from 0dB to + 18dB. Connection is made with a
cable using RJ-45 and can be installed under the dash for remote control
access.
