The Jensen Octane Power Amplifier, available in models XDA91RB, XDA92RB, and XDA94RB, is a Class-D amplifier designed to enhance a vehicle's audio system. This series of amplifiers is engineered for high performance and offers various configurations to suit different audio setups, from mono subwoofer applications to multi-channel speaker systems. The installation and owner's manual provides comprehensive guidance for setup, operation, and troubleshooting.
Function Description:
The Octane Power Amplifier serves as a central component in a car audio system, boosting the low-level audio signals from a head unit to drive speakers or subwoofers with increased power and clarity. It features a Digital Signal Processor (DSP) that allows for advanced audio customization and control via a dedicated smartphone or tablet application. The amplifier is designed to operate with both low-level (RCA) and high-level (speaker wire) input signals, offering flexibility for integration with various head units, including factory-installed systems.
Key functions include:
- Power Amplification: Delivers significant power output to speakers or subwoofers, improving sound quality and volume.
- DSP Control: Enables precise adjustment of audio settings such as crossovers, equalization (EQ), and RGB lighting directly from a mobile device.
- Crossover Functionality: Allows users to filter out unwanted frequencies, directing specific frequency ranges to appropriate speakers (e.g., Low-Pass Filter for subwoofers, High-Pass Filter for midrange/tweeters).
- Bass Boost: Provides an adjustable boost at 45Hz for enhanced low-frequency response, particularly beneficial for subwoofers.
- EQ Presets and Customization: Offers pre-defined EQ settings (Classic, Pop, Rock, Jazz) and the ability to create custom EQ profiles.
- RGB Color Control: Manages the amplifier's illumination, allowing users to turn it on/off or select single/multiple colors.
- Protection Circuitry: Features a "PROTECT" indicator (red LED) that illuminates when the amplifier detects a fault, safeguarding against damage.
