Amplifier with Helix M Six DSP processor

The Helix M Four DSP is more than "just" another six-channel amplifier - rather, despite its small size, you're dealing with a powerful control center that has a total of no less than ten processable DSP channels. In addition, the amplifier provides a rich output power of 100 W RMS per channel into 4 Ohm and 2 Ohm loads. Amazing value for money combined with a fantastic feature set.

The sound is absolutely Helix!

Compromises in terms of sound quality have no place in the HELIX product - which is why the M Six DSP is equipped with all the subtleties for perfect sound. Of course, the excellent and separate AD and DA converters are as natural as the DSP circuit board, which is completely manufactured in Germany. You'll find only excellent, separate AD and DA converters and extremely powerful DSP from Analog Devices. In addition, the six 6V preamplifier outputs provide more than enough level to drive any additional amplifier.

Maximum flexibility

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

Virtual Channel Processing - this is how signal routing works today

Many DSP channels need to be properly managed and configured - so there was no doubt that the M Six DSP also features Audiotec Fischer's innovative virtual channel processing. Adapting to modern OE audio systems through an increasing number of inputs has a significant impact on the complexity of signal routing inside the amplifier. In particular, when multiple input signals are mixed together and then re-distributed into multipath 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 acclaimed user-friendly DSP PC-Tool software makes it easy to implement even very complex system configurations. In addition, it allows you to freely assign our proprietary sound FX functions such as "RealCenter" or "Augmented Bass Processing".

Plus in speed – thanks to ACO

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

Compact, cool and totally practical

Despite the wide range of functions and enormous output power, the M FOUR DSP presents itself in the same classic, compact HELIX design with characteristic lines as the HELIX M FOUR or M ONE. Thanks to Class D amplifier technology, it keeps a "cool head" even at full power. And with features like start-stop, ADEP.3 circuitry and power saving mode, it's also ideally equipped for the everyday challenges of OEM integration.

Number of amplifier channelsAmplifiers are divided into: - Monoblocks - 2-channel - 3-channel - 4-channel - 5-channel - 6-channel - multi-channel Each channel is used to power one speaker for the coaxial type, or one side if they are component speakers. Monoblock type amplifiers are mainly used for subwoofers. 2-channel are suitable for both subwoofers and, for example, the front pair of speakers in a car. 3-channel is used for front or rear speakers + subwoofer. 4-channel are used for front + rear speakers or 1 pair of speakers + subwoofer. 6 or 5-channel are used for 2 pairs of speakers + subwoofer, most often. Bridging means connecting the amplifier to a bridge, using the + pole from one channel and the - pole from the other channel. In most cases this is shown as "BRIDGED" on the amplifier.	6
Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers.	D

Frequency rangeThe ability of the amplifier to reproduce the signal from the lowest frequency to the highest = faithfully reproduce the sound in a specific frequency band. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. Since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even specify this maximum tolerance of sound pressure in decibels in their catalogs for reasons of prestige. Data impoverished in this way is unfortunately worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness or undulation of the frequency curve in good speaker systems for high-quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural.	20 - 22000 Hz
Harmonic Distortion (THD)Total harmonic distortion indicates how much the input signal is distorted in the amplifier. Distortions appear as overtones contained in the output signal. The proportion of originally absent parts of the signal is given as a percentage, typical values are between 0.001% and 0.5%. Distortion is measured in their power band. If it exceeds the limit of 0.7% from a certain power, it is the value of the output power of the given amplifier, from which it no longer plays without distortion and from which the distortion usually increases steeply, so that no further increase in power can be counted on. The lower the value, the better.	< 0.03%
Signal-to-noise ratioThe signal-to-noise ratio means that the output signal always contains noise. The signal-to-noise ratio expresses how much of this noise is compared to the useful signal. The so-called A value is given, which does not take deep and very high frequencies into account. This corresponds to the characteristic of human hearing, which is not so sensitive to deep frequencies, especially below 1 kHz. The higher the value, the better the amplifier is.	105 dB
Damping factorDF - Damping Factor . It is the ratio of the load (repro + cables, crossover, etc.) to the internal resistance of the amplifier. The bigger the DF, the more controlled the bass. Amplifiers with a lower DF tend to hum. Subwoofers with a higher Q in the bass reflex and sometimes in the enclosure will also cause humming.	100
High level inputsThe high-level input on the amplifier allows connection directly to the existing speakers in the car without additional purchase of an external high/low adapter. Important equipment in the case of installing an amplifier on an original car radio.	Yes
Automatic on and offThis function allows you to automatically switch on the amplifier.	Yes
Socket input terminalsFerrule terminals allow better wiring contact to the amplifier. It is also a more secure form of terminals. If you are tightening the sleeve terminals, we recommend retightening them after 1 day, as the connected cable gradually compresses.	Yes
Remote control included in the packageSome models of amplifiers also come with wired remote controls in the package, which on one side plug into the amplifier and on the other side you have a potentiometer that you can place anywhere in the cabin. A common place to place the remote control is under the steering wheel. The advantage is the regulation of power, and therefore volume, depending on driving conditions and the mood of the crew in the car.	No
