Helix P TWO 24V - 2-channel amplifier

Helix P TWO 24Volt 

Power and sensitivity in abundance - the new P TWO combines two features in a unique way. With a continuous output power of 2 x 490 watts at 2 ohms, this compact amplifier is able to get even powerful subwoofers up to speed. The technical design is almost predestined for all woofers with 2 x 2 Ohm double voice coil, such as the new HELIX Q subwoofers.

Despite its sheer power, the P TWO is by no means a pure subwoofer amplifier. On the contrary - their Ultra HD Class D technology enables an extended audio frequency response of over 40 kHz, paired with a high damping factor, minimal distortion and an excellent signal-to-noise ratio. Thus, the P TWO is also the ideal playing partner for heavy-duty front systems in audiophile system configurations.

Special features

Ultra HD Class D amplifier technology

• Compared to conventional Class D amplifiers, this concept achieves an extended frequency response of up to more than 40 kHz with a reduced distortion factor thanks to a sophisticated new type of 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

• In the optical signal input, the HELIX P TWO uses a high-quality DA converter of the latest generation with a native resolution of 32 bits instead of the usual 24 bits. This results in unprecedented precision in signal conversion, which further optimizes the sound at lower signal levels. 

Intelligent high-level input

• Modern, factory-installed car radios are becoming more and more intelligent when it comes to diagnosing the connected loudspeakers. If an amplifier is connected to the radio instead, error messages or the loss of individual functions (e.g. faders) usually occur. The new ADEP circuit (Advanced Diagnostics Error Protection) prevents all these problems without unnecessarily loading the speaker outputs of the radio at high levels.

Start-stop capability

• The power pack in the HELIX P TWO amplifier ensures the internal power supply even in the event of short-term dips down to 6 volts. This ensures that the HELIX P TWO remains fully functional even when the engine is started.
