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.

The new G amplifiers are more than just impressive power packs. They unite innovative technology, extensive functionality and best sound with a very attractive price to performance ratio.
If we do not talk about their more obvious features, such as fully active crossovers with highpass, lowpass, bandpass, bass boost and input mode switch for flexible input signal routing and smart high level input with ADEP circuits, we can still talk about how the G series also provides Start-Stop capability which is an exceptional feature in this price range. Wait, that’s not all… a remote control for adjusting the subwoofer level is included as part of the deal.
With such an extensive list of features in this piece of equipment, it is really not hard to realize a sound system in your car that has a great sound and lots of power for when you need it most.
Furthermore, the G amplifiers have the compact and straight HELIX design that has become synonymous with HELIX. In addition, for those who love a good light show, the logo has been illuminated for your viewing pleasure.
