Features
Overview: The Rockford Fosgate Power T750X1bd is an ultra-compact mono-block amplifier. Even though the amplifier is only 8-1/2″ x 4-1/4″, it puts out a full 500 watts x 1 at 4 ohms, 750 x 1 at 2 ohms, or 750 x 1 at 1 ohm.
Class BD: The amplifier features Rockford Fosgate’s proprietary Class bd technology, which is more efficient than typical Class AB amplifiers, with lower distortion than Class D amps. Class AB amps typically have 20-60% efficiency, with the remaining power generating heat. Class bd amps are 75-80% efficient, creating more power to drive your speakers, and less creating heat.
Constant Power: Rockford Fosgate uses a patented circuit design to gain up to 25% more output power. Constant Power actively increases the voltage and current in direct relationship to the rise and fall of music signals to provide additional power.
Fan Cooled: The T750X1bd features extruded aluminum heat sinks and dual fans to keep the amp running cool. Dual Fan Forced Induction pulls in fresh air, which pulls heat off of the MOSFETs, and directs airflow into the exhaust channel and out of the amplifier. Since the top and bottom heat sinks are decoupled, the top remains cool to the touch. When installing, you should leave at least 2-3″ of clearance around the ends of the amplifier to optimize air flow to the fan intake and exhaust vents.
C.L.E.A.N. Technology: Using Rockford’s C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) technology, you can easily and precisely set up the amplifier levels to eliminate distortion from damaging your speakers. Simple LED indicators are used, instead of test equipment, to identify signal clipping at both the input and output, and to match the audio source to the amplifier.
Controls/Indicators
Top Mounted Controls: The T750X1bd features easy-to-reach controls on the top panel of the amplifier. These rotary controls can be set with a small screwdriver (not included). The controls include:
- Input Level: This rotary control lets you match the output of the audio source to the amplifier.
- Punch EQ: The Punch EQ eliminates frequency shift with boost. It functions as a 0 to +18dB variable Bass Boost at 45Hz.
- Frequency: The Butterworth crossover is internally set to Low Pass, and the cutoff frequency is constantly variable between 50Hz and 250Hz with a slope of 12dB/octave.
- Infrasonic Filter: The 2-way switch lets you engage (or turn off) the built-in Infrasonic Filter. The filter has a fixed cutoff frequency of 28Hz, with a slope of 12dB/octave. The Infrasonic Filter cuts out frequency below 28Hz that cause distortion, and are difficult for speakers to reproduce.
LED Indicators: The amplifier has three LED indicators on its top panel:
- Input Clip Indicator: The input clip indicator works in conjunction with the audio source’s volume knob. It will illuminate red when the audio source reaches its clipping point.
- Output Clip Indicator: The output clip indicator works in conjunction with the amplifier’s input level knob. It will illuminate red when the output level has reached the clipping point. When setting the level using test tones, you should adjust the output level until the LED glows blue. If setting the output level using music, the LED should glow blue with only an occasional red indication.
- Power/Protect: The Power LED illuminates blue when the unit is turned on. If the LED turns yellow, a short circuit or too low of an impedance has been detected at the speaker connections. If the LED turns red, the amp has overheated and has shut down.
Connections
Left Side of Amplifier:
- Remote Punch Level Control: This RJ45 jack lets you plug in the optional PLC2 Punch Remote Level Control. The control needs to be switched to the ON position in order to use the remote level control.
- Inputs: The 4-pin Molex connector works with the supplied RCA Input Harness. The amp will accept signals from either high-level (speaker) or low-level (RCA) sources. If connected to a high-level input signal, the amp’s auto turn-on feature is active.
Right Side of Amplifier:
- Power/Remote Terminals: The amplifier’s Power, Ground, and Remote terminals are located in a separate plug-in quick connector. The connector has compression terminals that will accept up to 8-gauge wire. When utilizing a high-level input signal, the auto turn-on feature is active, and the Remote terminal can be used as an output to turn on/off up to two additional amplifiers or other accessories. A small screwdriver (not included) is required to tighten/loosen the compression terminals. Once the wires are installed in the quick connector, the connector can be plugged into the amplifier.
- Note: The amplifier has no built-in fuses. It is recommended that a 100A fuse be placed on the power wire about 18″ from the battery.
- Speakers: The speaker output has removable compression terminals that will accept up to 10-gauge wire.
