Need help?Do you have a question about the B2 Audio rage 1500 and is the answer not in the manual?
The B2 Audio Rage series amplifiers are designed to elevate the car audio experience, offering a blend of power, precision, and compact design. These amplifiers are crafted for enthusiasts who demand high performance and exceptional sound quality, pushing the boundaries of what's considered standard in car audio. The Rage series embodies B2 Audio's commitment to integrating passion and soul into every product, ensuring a superior auditory journey.
The B2 Audio Rage series comprises high-efficiency Class D full-bridge amplifiers, including mono-channel models like the Rage 1500 and Rage 3200, and a four-channel model, the Rage 1200.4. These amplifiers are engineered to deliver substantial power output across a wide frequency range, ensuring accurate reproduction of audio signals from deep bass to crisp highs. The mono-channel amplifiers are optimized for driving subwoofers, providing robust power for impactful low-frequency response. The four-channel amplifier offers versatility for powering multiple speakers, allowing for a comprehensive sound system setup.
Each amplifier features a sophisticated crossover circuit, enabling precise control over the frequency range sent to connected speakers. The mono-channel amplifiers include variable low-pass and high-pass crossovers, allowing users to fine-tune the frequency response to match their subwoofer and enclosure characteristics. The four-channel amplifier provides similar crossover capabilities, with additional options for bandpass, full-range, or high-pass configurations on each channel, offering extensive flexibility for system integration.
The Rage series amplifiers are equipped with a remote control port, facilitating connection to an external level controller that often includes a voltmeter and clip sensor. This allows for convenient adjustment of the amplifier's output level and real-time monitoring of signal integrity, helping users prevent signal clipping and potential damage to their speakers.
Protection circuits are integrated into all Rage series amplifiers to safeguard against various fault conditions, including short circuits, speaker overload, and thermal issues. These circuits automatically shut down the amplifier in the event of a problem, indicated by a protection LED, thereby preventing severe damage to both the amplifier and connected components. The design also emphasizes efficient heat dissipation, with recommendations for vertical mounting to maximize cooling and ensure stable operation even under demanding conditions.
The Rage series amplifiers are designed for straightforward integration into various car audio systems. Installation begins with careful preparation, including disconnecting the battery and ensuring proper grounding. The amplifiers feature robust power and ground terminals, designed to accommodate heavy-gauge wiring for optimal current delivery and stability. External fuses are required for both the battery and amplifier connections, providing essential protection against short circuits.
Input sensitivity controls allow users to match the amplifier's input stage with the output level of their source unit, ensuring a clean and undistorted signal. The wide voltage range of the input sensitivity (6V to 0.2V) accommodates a variety of head units. For optimal performance, it is recommended to use a low input voltage, especially when driving the amplifier into low-ohm loads. RCA input terminals are provided for connecting the audio signal from the source unit, with an emphasis on using high-quality cables and routing them away from high-current wires to prevent noise and interference.
Speaker output terminals are designed for secure connections, with specific impedance recommendations to ensure safe and efficient operation. For the mono-channel amplifiers, a minimum load of 1 Ω is specified, and external bridging is not supported. The four-channel amplifier supports a minimum load of 2 Ω in stereo mode or 4 Ω when bridged, offering flexibility for different speaker configurations. Users are advised to measure voltage at the speaker terminals before making any changes to connections, as the circuit design maintains a high output voltage even after the amplifier is turned off.
The LED indicators on the amplifier provide visual feedback on its operational status. A lit power LED indicates that the amplifier is on and functioning. A flashing clip LED signals that the audio signal is approaching distortion, while a solid clip LED indicates heavy distortion, warning users to reduce the gain to prevent damage to speakers and the amplifier. The protect LED illuminates when the amplifier has shut down due to a fault, prompting users to troubleshoot the system.
While the Rage series amplifiers are built for durability, proper maintenance and troubleshooting are essential for long-term performance. The user manual provides a comprehensive troubleshooting guide to address common issues. If the amplifier fails to turn on, users are instructed to check voltage at the +12V and remote terminals, inspect ground connections, and verify in-line fuses. If the protection LED is lit, checks for speaker wire shorts, load impedance, and power cable integrity are recommended.
Overheating issues can be mitigated by ensuring adequate airflow around the amplifier and avoiding installation in areas prone to excessive vibration or upside-down mounting. If the amplifier experiences insufficient or distorted audio output, users should verify gain settings, adjust head unit volume, check speaker shorts, and ensure crossover frequencies are set correctly. RCA connections and cables should also be inspected for any faults.
To address "turn on thump," users can disconnect the signal input and observe if the noise is eliminated. Solutions include installing a delay turn-on module on the remote wire or using a separate 12V source for the remote lead with a relay to isolate the amplifier. For high hiss or alternator whine, it is crucial to route signal wires (RCA, speaker cables) separately from power and ground wires. Bypassing electrical components between the head unit and amplifier, ensuring proper grounding of all electrical components, and checking the battery and alternator load are also recommended steps.
Regular inspection of all connections—power, ground, remote, and speaker—is vital to ensure they are secure and free from corrosion. Adhering to the specified wire gauges and fuse ratings is also critical for maintaining optimal performance and safety. By following these guidelines, users can ensure their B2 Audio Rage series amplifiers provide many hours of high-quality audio enjoyment.
