Amplifier with DSP processor Helix V Twelve DSP MK2

The Helix V Twelve DSP MK2 is a new solution to the challenges of upgrading premium audio systems in today's vehicles. Like its predecessor, it combines 12 high-level inputs, 6 RCA inputs, 14 DSP channels and 12 power amplifiers with up to 160 RMS at 2 ohms in an ultra-compact case that only takes up the space of two envelopes.

Multifunctional amplifier

Even if the vehicle is already equipped with a premium sound system from the factory, the amplifier of which often already has more than 10 channels, the sound quality does not always meet one's expectations. In many cases, it is no longer possible to replace existing components, so only an amplifier with the same number of high-level inputs can be considered for expansion. For this reason, the HELIX V TWELVE DSP MK2 offers not only 12 high-level inputs, but also enough amplifier channels to ensure optimal adaptation to existing multi-channel sound systems. In addition, the V TWELVE DSP MK2 is also equipped with a digital input and HEC slot, with which the sound system can be expanded with other signal sources, such as Bluetooth streaming or the integration of a high-resolution audio player. The management of the fabulous fourteen (14!) separate channels of DSP is handled by a powerful integrated 64-bit DSP in conjunction with our unique DSP software for PC. In addition, the newly developed, future-ready Smart Control Port (SCP) facilitates the connection of accessories and, in addition to a compact and secure plug connection, offers an integrated power supply for remote controls such as CONDUCTOR or DIRECTOR, which significantly reduces the number of cables needed and thus the required installation space.

Virtual Channel Processing – this is how signal routing works today

Adapting to modern factory audio systems, the increasing number of signal inputs makes signal routing in the amplifier increasingly complex. Especially when multiple input signals are mixed together and then re-distributed into multipath systems, conventional routing concepts quickly reach their limits. Audiotec Fischer's new, multi-level "Virtual Channel Processing" in conjunction with the acclaimed, user-friendly DSP PC-Tool software makes it possible to easily map even very complex system configurations and freely assign proprietary audio FX functions such as "RealCenter" or "Dynamic Bass Enhancement" , so that you can But with its huge number of channels, the V TWELVE DSP MK2 is also a prime example of applications where 1:1 routing (IOR) makes sense.

Fast computing power - thanks to ACO

Such a huge number of channels not only requires processing power in the signal path - Audiotec Fischer's own 32-bit ACO platform takes over all control tasks and ensures enough speed, especially for data communication with our DSP PC-Tool software, but also for lightning-fast switching between up to ten possible sound settings. The fantastic sound effects associated with the ACO platform, such as extended bass processing, StageXpander or RealCenter, are as natural in the V TWELVE DSP MK2 as the 12-channel input EQ including the Input Signal Analyzer (ISA) for easy input analysis and compensation. signals from OE -Radios.

Perfect sound without compromise

The sound performance of the new HELIX V TWELVE DSP MK2 is as strong as its range of features. High-efficiency Class GD technology and BurrBrown's most advanced AD and DA converters ensure optimal audio performance, the best possible signal-to-noise ratio and minimal harmonic distortion. The TWELVE DSP MK2 is therefore an absolute sonic masterpiece despite the extremely high flexibility and very compact design and does not have to hide from the absolute top.

GD class amplifier technology

AudioD Fischers Pure Class GD proprietary concept takes the efficiency of conventional Class D amplifiers to the next level. By varying the internal supply voltage in response to the input signals of the amplifier, no-load losses are significantly reduced and overall efficiency is close to maximum at all times. Heat dissipation is therefore almost negligible, allowing for the smallest heat sinks and the most compact form factors. In addition, the Pure Class GD amplifier outperforms conventional Class D designs in terms of sound quality by implementing a fully differential signal path and improved output filter design.

ACO - Advanced 32-bit CoProcessor

The HELIX V EIGHT DSP MK2 contains an extremely powerful 32-bit CoProcessor of the latest generation for all monitoring and communication tasks, internally and externally. Unlike the generation of 8-bit predecessors, this MCU achieves much higher speed with regard to switching settings and data communication with our DSP PC-Tool software. Another significant advantage is the integrated native CoProcessor bootloader. It allows software updates of all components of the integrated DSP in order to adapt the ADEP.3 circuit controlled by microcontrollers, for example, to the future requirements of the diagnostic system of production radios or if the device is expanded with additional interfaces. In addition, thanks to the new flash memory, the ACO offers 10 regular memory settings instead of the usual two.

ADEP high level smart input.3

Modern factory-installed car radios include sophisticated diagnostic options for connected speakers. Especially the latest generation of car radios are equipped with additional monitoring functions, so error messages and loss of specific functions (eg fader functions) often appear if the amplifier is connected - but not with the V EIGHT DSP MK2. The new ADEP.3 (Advanced Diagnostics Error Protection, 3rd generation) circuit avoids these problems without unnecessarily loading the OE radio speaker outputs at high volumes.

Start-Stop option

The switching power supply of the HELIX V EIGHT DSP MK2 ensures a constant internal supply voltage, even if the battery voltage drops to 6 V during engine cranking.

Power saving mode

Power saving mode is part of the basic settings. It allows to significantly reduce the power consumption of the amplifiers that are connected to the HELIX V EIGHT DSP MK2 when no input signal is present for more than 60 seconds. Please note that in many modern cars with a "CAN" or other internal bus structure, the radio may remain "invisible" on for up to 45 minutes. even after locking and leaving the vehicle! When "Power Save Mode" is active, the remote output and connected amplifiers will be turned off. When a music signal is applied, the V8 EST DSP MK2 activates the remote output within one second. It is possible to change the shutdown time to 60 seconds. or completely disable "Power Saving Mode" using the DSP PC-Tool software.

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.	12
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.	GD

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.	< 0.015%
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.	107 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.	> 70
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
