P Series – Spectacular Processing Teamed With Awesome Firepower
When it comes to fusing a comprehensive digital sound processor together with a powerful amplifier, there’s few companies that possess the technical acumen required to achieve the feat successfully. If however you’re referring to the Helix P series designs then you’re not only talking about a company more than able pull it off, you’re in fact looking at the range of products against which all others are measured. For these units are the absolutely masters of their class.

Design Ideologies
The P SIX DSP ULTIMATE six channel amplifier delivers enormous power and sophisticated processing technology in perfect harmony. Up to 285 watts per channel into 2 Ohms and the integrated twelve channel signal processor with doubled processing power guarantee an incomparable sound experience in high resolution quality. Helix high definition class D philosophy focuses on combining the excellent sound characteristics of class AB technology with the efficiency of a digital amplifier. In addition, the integration of numerous new functions and features, such as the ACO platform, the optical digital output and much more, make one thing clear; the P SIX DSP ULTIMATE is in a league of its own. For state-of-the-art technology plus twin DSP power adds up to the ultimate high resolution sound experience

The P SIX DSP ULTIMATE is equipped with two most powerful 64-bit audio signal processors from Analog Devices. The incredible processing power of 2.4 billion MAC operations per second, combined with the high sampling rate of 96 kHz, provides an audio bandwidth of over 40000 Hz, as well as the BurrBrown A/D and D/A signal converters, ensure outstanding sound in high resolution quality. In addition, the complete audio signal path including the new more powerful power supply; has been optimized down to the last detail.

Advanced 32-Bit CoProcessor Platform
The P SIX DSP ULTIMATE is equipped with Helix’s proprietary 32-bit ACO platform. This processor doesn’t just handle all control tasks ultra-fast, it undertakes a bunch of audio function, functions including augmented bass processing or RealCenter are implemented, as well as a channel separated Input EQ including input signal analyser for easy analysis and compensation of input signals of OEM radios, many of which include heavily processed sound.

With its wide range of inputs and outputs including 6 x high-level, 6 x RCA, 1 x optical SPDIF, 1 x coaxial SPDIF, 1 x HEC slot, 4 x line output & 1 x optical output); the P SIX DSP ULTIMATE offers everything for an easy adaption to existing factory radios or multi-channel OEM sound systems. The extended voltage range up to 32 Volts allows the combination with almost any imaginable analogue signal source, even with high-power OEM amplifiers. Furthermore the integration of the optical digital output enables a completely digital signal chain with downstream amplifiers, for example the P ONE MK2 or P TWO MK2. Last but not least, virtual channel processing (VCP) is now included for the flexible and easy configuration of even highly complex sound systems.

PC-Tool 5 Featuring TuneEQ
The user software offers powerful features to achieve the ultimate sound experiences. The P SIX DSP ULTIMATE can be easily configured via the latest version of the professional and exceptionally intuitive DSP PC-Tool 5 software. The numerous setting options with their extensive sound processing functions leave nothing to be desired, guaranteeing an extremely precise sound adjustment even under the most austere conditions. And thanks to the new, proprietary TuneEQ function for automated frequency response correction, you can save a lot of time when optimizing your sound.

TuneEQ is an extremely flexible and particularly easy-to-use function for automated frequency response correction. A single measurement per audio channel or channel pair with a suitable measurement microphone such as the Helix MTK1 is sufficient for TuneEQ to independently and precisely adjust the equalizers to the desired reference curve. TuneEQ uses the full function set of the parametric equalizer including center frequency, Q-factor and gain adjustment. And since the highly complex arithmetic operations required for this run in the background, you also save a lot of time when optimizing your sound with TuneEQ.

Ultra High-Definition Class D Amplifier Technology
Compared to conventional class D amps this concept achieves an extended frequency response to more than 40000 Hz, in combination with reduced distortion thanks to an advanced integrated feedback design. Ultrahigh-definition class D achieves outstanding class AB like sound quality combined with the efficiency of a class D amplifier.

Ready For 24 Volts
It is possible to operate the P SIX DSP ULTIMATE with a supply voltage of 12 Volts or 24 Volts, say for example many trucks; without the need to make any changes to the unit. In both operating modes the amplifier will have equal performance characteristics. This guarantees maximum flexibility for numerous applications.

Smart High-Level Input ADEP.3
Modern factory installed audio systems incorporate sophisticated abilities that diagnose all connected speakers. Latest generations of cars are equipped with additional monitoring functions so that failure messages and loss of specific features such as parking sensor and lane departure warnings often appear if a signal processor is plumbed in. Not with the P SIX DSP ULTIMATE though. The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OEM radio during high volumes unnecessarily.

Start-Stop Capability
The switched power supply of the P SIX DSP ULTIMATE assures a constant internal supply voltage even if the battery’s voltage drops to six volts during engine cranking.

Power Save Mode
The Power Save Mode is also incorporated. It allows to significantly reduce the power consumption of the amplifiers that are connected to the processor once there’s no input signal present for more than sixty seconds. Many newer cars utilising digital networks and other internal bus structures may remains invisibly turned on for up to 45 minutes after you’ve locked the car! Once the power save mode is active the remote output and therefore the connected amplifiers will be turned off. The processor then reactivates the remote output within a second if a music signal is applied. It is possible to either modify the turn-off time or completely deactivate the function via PC-Tool software.

Automatic Signal Detection
Switching from analogue input to one of the digital inputs is done automatically as soon as a signal is detected on the optical or coaxial input. This feature can be deactivated in the DSP PC-Tool software. Alternatively you can use an optional remote control for manual switching between sources.

RealCenter
The RealCenter feature is an algorithm developed by Audiotec Fischer that emphasizes the music information which is present in both the left and right front channel to create an unique centre signal. In contrast to common procedures, in which only the channels are summed up; the intensity of the centre signal is also dynamically controlled by the stereophonic informational content of the left and right channel.

Sounds complicated but this effect is astonishing: That means if solely the left or right channel delivers an audio signal, the centre channel will not reproduce a signal. In the case of common algorithms the volume level of the centre channel is only reduced by 6 dB. Audiotec Fischer’s RealCenter allows a unique, broadened sound staging for both driver and co-driver at the same time! Therefore, the disadvantages of a conventional center channel such as an intrusive, small sound stage, are things of the past.

Augmented Bass Processing
Audiotec Fischer’s proprietary augmented bass processing consists of the two revolutionary sound features called Dynamic Bass Enhancement and SubXpander. These have been especially developed to dramatically improve the bass reproduction of subwoofers. The dynamic bass enhancement ingeniously combines maximum deep bass and highest sound pressure regardless of the music style or the tone controls in the head unit. Depending on the input signal, the dynamic bass enhancement gains the lower frequency range and varies the cut-off frequency of the subsonic filter. The result is a significantly more powerful and deeper bass response at low and medium volume levels without the risk of overloading the subwoofer neither mechanically nor electrically at high volume levels. It is simply fascinating how much subbass performance is suddenly possible.

If you want an even lower and darker bass reproduction, the SubXpander can be additionally activated. In doing this, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.
