HELIX P TWO - 2 Channel 1100 Watts High-Res Car Amp Amplifier With Integrated, Active Crossover And Digital Signal Input
Power and sensitivity abound - the new P TWO combines two features in a unique way. With a continuous output power of 2 x 490 watts into 2 ohms, this compact amplifier is able to get powerful subwoofers on their toes. The technical concept for all woofers with 2 x 2 ohm double voice coils, such as the new HELIX Q subwoofers, is virtually predestined.
But despite its sheer power, the P TWO is by no means a pure subwoofer amplifier. On the contrary, their Ultra HD Class D technology allows for extended audio response up to 40kHz, coupled with high attenuation factor, lowest distortion, and excellent signal-to-noise ratio. Thus, the P TWO is equally the ideal game partner for heavy-duty front systems in audiophile system configurations.
Features:
- "Ultra HD Class D" concept that combines the sound quality of the Class AB technology with the advantages of a Class D amplifier
- Two speaker outputs each with 490 watts RMS to 2 ohms
- Digital SPDIF format optical signal input including SPDIF Direct In switch to route the digital input signal directly to the power amplifier
- BurrBrown DA converter of the latest generation with 32-bit resolution
- Integrated, active crossover with high pass, low pass, bandpass and configurable bass boost
- Intelligent high-level input with ADEP circuit
- Wired remote control for volume control
- Extremely compact dimensions and low heat generation thanks to very high efficiency
Special features:
Ultra HD Class D Amplifier Technology
Compared to traditional class D amplifiers, this concept achieves an extended frequency response of over 40kHz with reduced harmonic distortion through ingenious new negative feedback. The result: the sound quality of a Class AB amplifier combined with the efficiency of Class D concepts.
Signal converter with native 32-bit resolution
The HELIX P TWO uses a high-quality DA converter of the latest generation in the optical signal input with a native resolution of 32 bits instead of the usual 24 bits. This results in unprecedented signal-conversion precision, which further optimizes sound at lower signal levels.
Intelligent high-level input
Modern, factory-installed car radios are becoming increasingly intelligent in terms of diagnosing the connected speakers. If an amplifier is connected to the radio instead, it usually results in error messages up to the elimination of individual functions (such as faders). The new Advanced Diagnostics Error Protection (ADEP) circuitry eliminates all of these problems without unduly stressing the radio's speaker outputs at high levels.
Start Plugability
The power supply in the HELIX P TWO amplifier ensures the internal power supply even with short-term drops down to 6 volts. This ensures that the HELIX P TWO remains fully functional even when the engine is started.
