HELIX M SIX DSP

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. Compared to the 8 Bit predecessor,
this MCU achieves much higher speeds in setup switching and data communication. The integrated native
bootloader allows software upgrades of all components, ensuring future-proof operation.

Smart highlevel input ADEP.3

Modern car radios diagnose connected speakers, causing failure messages if an amplifier is added – but not
with the M SIX DSP. The new ADEP.3 circuit avoids these issues without unnecessarily loading speaker outputs.

Power Save Mode

Power Save Mode reduces power consumption after 60 seconds of no signal. The amplifier will automatically
reactivate within a second when a music signal is detected. The turn-off time can be modified via the DSP PC-Tool.

Start-Stop capability

The switched power supply ensures stable internal voltage, even when the car battery drops to 6 Volts during engine crank.

DSP Features

TuneEQ

TuneEQ is a flexible function for automated frequency response correction. A single measurement per channel
with a measurement microphone is sufficient for TuneEQ to adjust equalizers precisely, saving time while
optimizing your sound.

RealCenter

RealCenter emphasizes the information present in both left and right channels, creating a unique, widened
center signal that avoids the narrow sound stage of conventional setups.

Augmented Bass Processing

Augmented Bass Processing combines Dynamic Bass Enhancement and SubXpander to deliver deeper, more powerful
bass, regardless of music style, without overloading the subwoofer at high volume levels.
