Key Features

• Massive 5500W RMS Power at 1 Ohm: Delivers an impressive 1 × 5500W RMS output at a 1 Ohm load, providing substantial amplification power for demanding automotive audio systems and high-power speaker configurations.
• Full-Range Class D Amplification: Features Class D Full-Range amplifier technology, designed to deliver efficient, high-power amplification across a broad audio frequency spectrum while reducing energy losses compared with conventional Class A/B amplifier designs.
• Adjustable Low-Pass Filter: Equipped with an adjustable 100Hz–20kHz low-pass filter with a 12dB/octave slope, providing frequency control to help tailor the amplifier's output to the connected audio system.
• Adjustable Subsonic Filter: Features a 10Hz–2kHz subsonic filter with a 12dB/octave slope, allowing users to manage unwanted low-frequency signals and optimise performance for compatible speakers and subwoofer enclosures.
• Customisable 0–12dB Bass Boost: Includes an adjustable bass boost function from 0 to 12dB, enabling users to increase low-frequency emphasis according to their preferred sound characteristics and system requirements.
• 95dB Signal-to-Noise Ratio: Features a specified 95dB signal-to-noise ratio, helping maintain clear audio reproduction and minimise unwanted background noise when the amplifier is properly installed.
• Built-In Overvoltage Protection: Incorporates an overvoltage protection circuit designed to help safeguard the amplifier against excessive supply voltage.
• Output Short-Circuit Protection: Includes speaker output short-circuit protection, helping reduce the risk of amplifier damage caused by wiring faults or short circuits.
• Thermal Overheating Protection: Features overheating protection designed to respond to excessive operating temperatures and help protect internal amplifier components during demanding use.
• Designed for High-Power Audio Installations: Suitable for custom car audio systems, high-output subwoofer setups and compatible full-range speaker applications, provided the speakers, wiring and vehicle electrical system meet the installation requirements.
