The new king of multitools

The V Twelve DSP MK2 is designed to solve the complexity of upgrading premium OE sound systems in modern vehicles. It combines 12 high-level inputs, 6 RCA inputs, 14 DSP channels and 12 output stages with up to 160 W RMS at 2 ohms — all in an ultra-compact housing with the footprint of just two envelopes. Need fewer channels? The Helix Amplify 206 DSP offers a more compact 6-channel amplifier with an 8-channel DSP.

Virtual Channel Processing – signal routing for modern OE systems

Adapting to modern OE sound systems with a high input count makes signal routing inside an amplifier increasingly complex — especially when multiple inputs are mixed and then split into multi-way systems. Audiotec Fischer's multi-stage Virtual Channel Processing, combined with the DSP PC-Tool software, makes even highly complex system configurations straightforward. It allows free assignment of proprietary FX features such as RealCenter and Augmented Bass Processing. The V Twelve DSP MK2's high channel count also makes it equally suited to simpler 1-to-1 IOR routing applications.

Rapid processing power – thanks to ACO

Managing this many channels demands fast processing throughout the signal path. Audiotec Fischer's 32-bit ACO platform handles all control tasks, delivering exceptional speed for data communication with the DSP PC-Tool software and lightning-fast switching between up to ten sound setups. The ACO platform also enables sound effects including Augmented Bass Processing, StageXpander and RealCenter, alongside a 12-channel input EQ with Input Signal Analyzer (ISA) for easy analysis and compensation of OE radio input signals.

Perfect sound without compromises

The highly efficient Class GD technology and BurrBrown A/D and D/A converters deliver optimal sound performance, a strong signal-to-noise ratio and low distortion. Despite its high flexibility and compact dimensions, the V Twelve DSP MK2 holds its own against top-class competition.

About the Helix HA11208

From our tech experts at CEN

The Helix V Twelve DSP MK2 is a 12-channel Class GD amplifier with a 14-channel 64-bit DSP built in. It delivers 12 x 75 W RMS at 4 ohms and 12 x 120 W at 2 ohms, with two extra processed RCA outputs, in a housing just 44 x 220 x 220 mm.

Who it suits

Owners of premium factory systems with many speakers who want every channel amplified and tuned from one compact unit. Its 12 high-level inputs take the factory signal directly. If fewer channels will do, the V Eight DSP MK2 offers eight amplified channels and ten DSP channels.

Our tech experts advise

There are also six RCA inputs and an optical input, and a Control Input-to-SCP adaptor comes in the box for Helix remotes. The amplifier does its best work once the DSP is set up with in-car measurements and time alignment. Installation and tuning are priced per vehicle, so get in touch with your make, model and year.
