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:

1. 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).
2. Protect LED – The (red) LED illuminates when the unit is latched into protection. It requires momentary AP removal to enable output PWM.
3. 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.
4. Phase – Used when connecting two bd amplifiers together to phase one amplifier 180° from the other.
5. 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.
6. LED Power Indicator – The LED illuminates when the unit is turned on.
7. 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.
8. 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.
9. 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.
10. 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.
11. REM Terminal – This terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied.
12. 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.
13. 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.
14. 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.
