HELIX M SIX DSP

CALL FOR CURRENT PRICING

That rocks – the new M SIX DSP

The M SIX DSP is more than “just” another six-channel amplifier – rather, despite its small dimensions, you are dealing with a powerful control center that has not less than a total of ten processed DSP channels. In addition, the amplifier delivers plentiful output power with generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load.
Finally its awesome price performance ratio in combination with the fantastic feature set will ensure bright eyes.

Tonally absolutely HELIX!

Compromises in terms of sound quality have no place in a HELIX product – and that's why the M SIX DSP is equipped with all the finesse for perfect sound. Of course, excellent and separate A/D and D/A converters are just as natural as on the DSP circuit board, which is completely manufactured in Germany, you will find only excellent, separate A/D and D/A converters as well as an extremely powerful DSP from Analog Devices. In addition, the four pre-amplifier outputs with 6 Volts output voltage provide more than enough level to drive any additional amplifier.

Maximum flexibility

Even the internal amplifier section of the M SIX DSP is extremely variable – it can either be operated in 6-channel mode or, thanks to its bridging capability, can also be configured as a 5-channel, 4-channel or even 3-channel amplifier.
But that's not all – in connection with the four pre-amplifier outputs, the sound system can be expanded in a diverse manner and upgraded to up to 10 channels.
In combination with other amplifiers of the M series (M ONE X, M ONE, M FOUR or M SIX), there are more than enough possibilities to expand the number of power channels.
This makes complex, yet affordable and, above all, space-saving multi-channel systems with enormous performance possible.

Virtual Channel Processing – that´s how signal routing works today

Many DSP channels need to be managed and configured properly – so there was no question that the M SIX DSP is also equipped with Audiotec Fischer's innovative virtual channel processing.
The adaptation to modern OE sound systems via an increasing number of inputs has a significant impact on the complexity of the signal routing inside the amplifier. Especially when several input signals are mixed together and then split again into multi-way systems, conventional routing concepts quickly reach their limits, both in terms of implementation and usability. Audiotec Fischer's new multi-stage "Virtual Channel Processing", in conjunction with the recognized user-friendly DSP PC-Tool software makes it easy to realize even highly complex system configurations. Besides, it allows to freely assign our proprietary FX sound features such as "RealCenter" or "Augmented Bass Processing".

The plus in speed – thanks to ACO

Faster is better – the particularly powerful 32 Bit ACO platform takes over all control tasks and ensures significantly more speed, especially for data communication with our DSP PC-Tool software but also for the lightning-fast switching between up to ten sound setups. But ACO offers much more – fantastic sound effects such as Augmented Bass Processing or RealCenter are implemented as well as a channel-separated Input EQ including the Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios that already include an “ex works” sound setup.

Compact, cool and absolutely practical

Despite its vast range of functions and huge output power the M SIX DSP presents itself in the same classic, compact HELIX design with distinctive lines like a HELIX M SIX. Thanks to its Class D amplifier technology, it keeps a "cool head" even at full power. And thanks to features such as start-stop capability, ADEP.3 circuit and power save mode, it is also ideally equipped for the now everyday challenges of OEM integration.

Special features:

ACO – Advanced 32 Bit CoProcessor

The HELIX M SIX DSP incorporates an extraordinary powerful 32 Bit CoProcessor of the latest generation for all monitoring and communication tasks, both internally and externally. In opposite to the 8 Bit predecessor generation this MCU achieves way higher speeds with respect to setup switching and data communication with our DSP PC-Tool software. A further significant advantage is the integrated, native boot loader of the CoProcessor.
It allows software upgrades of all components of the integrated DSP in order to adjust the microcontroller-controlled ADEP.3 circuit for example to future requirements of the diagnostic system of factory radios or if the device will be extended with additional interfaces. In addition, thanks to the new flash memory, the ACO offers 10 memory locations for sound setups instead of the common two.

Smart highlevel input ADEP.3

Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. In particular the latest generation of car radios are equipped with additional monitoring functions so that failure messages and loss of specific features (e.g. fader function) quite often appear if an amplifier will be hooked up – but not with the M SIX DSP.
The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Power Save Mode

The Power Save Mode is incorporated in the basic setup. It allows to significantly reduce the power consumption of the amplifiers that are connected to the HELIX M SIX DSP once there’s no input signal present for more than 60 seconds. Please note that in many up-to-date cars with “CAN” or any other internal bus structures it may happen that the radio remains “invisibly” turned on for up to 45 min. even after locking and leaving the car! Once the “Power Save Mode“ is active the remote output and therefore the connected amplifiers will be turned off.
The M SIX DSP will reactivate the remote output within a second if a music signal is applied. It is possible to either modify the turn-off time of 60 sec. or completely deactivate the “Power Save Mode” via the DSP PC-Tool software.

Start-Stop capability

The switched power supply of the HELIX M SIX DSP assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.
