Helix P TWO
Plenty of power and sensitivity – the new P TWO combines two talents in an absolutely unique way. Due to its RMS output power of 2 x 490 Watts into two Ohms, this compact amplifier is able to drive even powerful subwoofers to the max. The technical design is literally predestinated for all woofers with 2 x 2 Ohms dual voice coil like the new HELIX Q subwoofers.
But despite its sheer force the P TWO is by no means a pure subwoofer amplifier. On the contrary, the Ultra HD Class D concept combines an extended frequency response above 40 kHz with high damping factor, minimal distortion and excellent signal-to-noise ratio. Therefore, this amplifier is likewise a perfect buddy for heavy-duty front speakers in audiophile system concepts.

Match M 5DSP
As small as a cigarette packet but a giant in performance and function: the brand-new M 5DSP amplifier provides huge power and cutting edge technology in a remarkably small housing.
Five channels, a powerful 7-channel “fixed point” Audio DSP with 56 Bit resolution and proprietary Class GD technology predestine the amplifier for ultimate car audio performance. Its minimal dimensions as well as its high efficiency and low heat dissipation allow unprecedented space saving and hidden installation concepts, that were not previously possible.
The M 5DSP is featuring two power modes: it can be driven optionally in “HighPower” mode for maximum performance or in “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications.
A subwoofer output, a remote output and a freely configurable 2-channel PreOut for hooking up additional amplifiers offers further connectivity.
Thanks to Audiotec Fischer’s DSP PC-Tool software the integrated DSP can easily configured to individual requirements. The scope of delivery includes a connection cable and an adapter cable to dock a MATCH Plug & Play or a conventional subwoofer.
