Малката промяна в името MK2 всъщност е голяма промяна във вътрешността на модела. Увеличената скорост е благодарение на 32-битовия допълнителен процесор ACO, който подпомага комуникацията между DSP PC-Tool софтуера и усилвателя както и за мигновенното превключване през запаметени звукови сетъпи. ACO платформата обаче предлага повече! Звукови ефекти като Augmented Bass Processing и RearCenter са внедрени в софтуера, а спектрален анализатор на входния сигнал (Inpus Signal Analyzer ISA) помага за линейната настройка и компенсира недостатъците на фабричните източници.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eНови сигнални конвертори за оптимизация на качеството на звука\u003c\/strong\u003e\u003cbr\u003e\nВместо комбинирани кодеци, новият V EIGHT DSP MK2 използва отделни AD и DA конвертори от последното поколение на Asahi Kasei с 32-битова резолюция.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVirtual Channel Processing – that´s how signal routing works today\u003c\/strong\u003e\u003cbr\u003e\nThe 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“.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaximum connectivity\u003c\/strong\u003e\u003cbr\u003e\nПовече и повече от съвременните автомобили са оборудвани с фабрични аудио системи с мултиканален усилвател, който не може просто да бъде заменен с друг. Адаптацията на нова аудио система в тази ситуация изисква не само мултиканален вход по високо ниво, но и възможност за регулиране на входната чувствителност. За това Helix V Eight DSP MK2 е оборудван както със шест RCA входа така и с 8 входа по високо ниво с входно напрежение от 4V до 32V. Разбира се V Eight DSP MK2 е снабден и с последното поколение ADEP.3 електроника (Advanced Diagnostic Error Protection) за безпроблемно интегриране към фабрични аудио системи.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eДо 160 W RMS изходна мощност на канал при 2Ω\u003c\/li\u003e\n\u003cli\u003e“Pure Class GD” концепция за превъзходно качество на звука в комбинация с най-добрата производителност\u003c\/li\u003e\n\u003cli\u003eМощен 64 битов “fixed point” аудио DSP\u003c\/li\u003e\n\u003cli\u003eACO – Advanced 32-битов допълнителен процесор за DSP функции като:\n\u003cul\u003e\n\u003cli\u003eISA (Спектрален анализатор на входния сигнал) и InputEQ за анализ и корекция на входния сигнал\u003c\/li\u003e\n\u003cli\u003eSFX специални звукови ефекти – Augmented Bass Processing, StageXpander, RealCenter \u0026amp; Co.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e1 to 1 Input \/ Output Routing (IOR) – same number of highlevel inputs and amplifier outputs\u003c\/li\u003e\n\u003cli\u003eVirtual Channel Processing (VCP) allows even more flexible configuration for highly complex sound systems\u003c\/li\u003e\n\u003cli\u003eHELIX Extension Card slot (HEC) for additional input \/ output modules like Bluetooth\u003csup\u003e®\u003c\/sup\u003e Audio Streaming, High Resolution Audio Streaming via USB etc.\u003c\/li\u003e\n\u003cli\u003eКомпактен дизайн с ниски нива на загряване поради оптимална ефективност\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecial features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePure Class GD amplifier technology\u003c\/strong\u003e\u003cbr\u003e\nAudiotec Fischers proprietary Pure Class GD concept takes the efficiency of conventional Class D amps to the next level. By varying the internal supply voltage depending on the amplifier’s input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time.\u003cbr\u003e\nSo heat dissipation is almost negligible thus allowing smallest heat sinks and most compact form factors. Besides that Pure Class GD amp outperforms conventional Class D designs in terms of sound quality by implementing a fully differential signal path and improved output filter design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eACO – Advanced 32 Bit CoProcessor\u003c\/strong\u003e\u003cbr\u003e\nThe HELIX V EIGHT DSP MK2 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.\u003cbr\u003e\nIt 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmart highlevel input ADEP.3\u003c\/strong\u003e\u003cbr\u003e\nModern, 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 V EIGHT DSP MK2.\u003cbr\u003e\nThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStart-Stop capability\u003c\/strong\u003e\u003cbr\u003e\nThe switched power supply of the HELIX V EIGHT DSP MK2 assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Save Mode\u003c\/strong\u003e\u003cbr\u003e\nThe 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 V EIGHT DSP MK2 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.\u003cbr\u003e\nThe V EIGHT DSP MK2 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.\u003c\/p\u003e\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower RMS ≤ 1% THD+N\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e– @ 4 Ohms\u003c\/td\u003e\n\u003ctd\u003e75 Watts per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e– @ 2 Ohms\u003c\/td\u003e\n\u003ctd\u003e120 Watts per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e– @ 1 Ohm\u003c\/td\u003e\n\u003ctd\u003e–\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e– bridged @ 4 Ohms\u003c\/td\u003e\n\u003ctd\u003e–\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e– bridged @ 2 Ohms\u003c\/td\u003e\n\u003ctd\u003e–\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax. output power per channel*\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 160 Watts RMS @ 2 Ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmplifier technology\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePure Class GD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 x RCA \/ Cinch\u003cbr\u003e\n8 x Highlevel speaker input\u003cbr\u003e\n1 x Optical SPDIF (12 – 96 kHz)\u003cbr\u003e\n1 x Remote In\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput sensitivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRCA \/ Cinch max. 4 V or max. 8 V\u003cbr\u003e\nHighlevel max. 16 V or max. 32 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput impedance RCA \/ Cinch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 kOhms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput impedance highlevel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9 – 33 Ohms or 20 kOhms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutputs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 x Speaker output\u003cbr\u003e\n2 x RCA \/ Cinch\u003cbr\u003e\n2 x Remote Out\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput voltage RCA \/ Cinch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3 Volts RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 Hz – 22,000 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDSP resolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e64 Bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDSP power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e295 MHz (1.2 billion MAC operations\/second)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSampling rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e48 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDSP type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAudio signal processor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal converters\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eA\/D: AKM 32 Bit\u003cbr\u003e\nD\/A: AKM 32 Bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal-to-noise ratio digital input\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e107 dB (A-weighted)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal-to-noise ration analog input\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e102 dB (A-weighted)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDistortion (THD)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;
