The HELIX P SIX DSP MK2 6-Channel Amplifier also incorporates advanced 8-Channel DSP with exceptional processing power. This fusion sets a completely new standard with its "Ultra HD Class D" amplifier technology.
With a sampling rate of 96kHz and an extended audio bandwidth of over 40kHz, this precision engineered prowess raises the bar in terms of sound quality.
If we put that aside for a moment, versatility is another important milestone to be achieved during the development process. Therefore, we are pleased to introduce HEC. The HELEC Extension Card (HEC) slot allows you to extend the possibilities of your devices far beyond ordinary RCA sockets. Interfaces such as a Bluetooth ® audio streaming module or a high resolution USB sound card have been created to give you more options than ever before.
Two fully processed RCA outputs provide connectivity for daisy-chaining multiple amplifiers without the need for a second DSP.
Setting up the internal 64-bit DSP couldn't be easier thanks to the professional and user-friendly PC-Tool DSP software that offers almost unlimited sound optimization capabilities.
Despite this impressive engineering feat, the P SIX DSP MK2 has not lost its HELIX design heritage; It still has a clean design while remaining very compact for easy installation.
Ultra HD Class D amplifier technology with 96kHz sampling rate
The HELIX P SIX DSP MK2 is the first Class D amplifier with integrated DSP on the market that operates at a sampling rate of 96kHz. Thus, the audio bandwidth is no longer limited to 22kHz, but allows for an extended frequency response beyond 40kHz. The higher sampling rate was only possible by implementing the latest DSP chipsets and amplifiers. The result: a Class D amplifier with unprecedented sound quality.
Ready for 24V.
It is possible to operate the P SIX DSP MK2 with a supply voltage of 12 Volt or 24 Volt (for example, as usual in trucks) without the need to make any changes to the unit. In both operating modes the amplifier will have equal performance characteristics. This ensures maximum flexibility for numerous applications.
High-end intelligent entrance
The latest generation OE car stereos incorporate sophisticated possibilities for diagnosing the connected speakers. If a normal amplifier is connected, the results are often error messages and the loss of specific functions (e.g. fader function), but not with the P SIX DSP MK2. The new ADEP (Advanced Diagnostics Error Protection) circuit avoids all these problems without loading the OE radio speaker outputs in case of unnecessary high volumes.
Energy saving mode
Energy saving mode is built into the basic settings. It allows to significantly reduce the power consumption of the P SIX DSP MK2 and connected amplifiers when there is no input signal for more than 60 seconds. Please note that in many cars updated with "CAN" or any other internal bus structure it may happen that the radio remains "invisibly" on for up to 45 minutes. even after leaving the car! Once "Energy Saver Mode" is activated, the remote output (Rem Out) and internal stages of the amplifier will be deactivated. The HELIX P SIX DSP MK2 will reactivate the remote output and internal amplifier stages within one second if a music signal is applied. The shutdown time can be changed by 60 sec. or completely deactivate the "Energy saving mode" via the DSP PC-Tool software.
The switching power supply of the HELIX P SIX DSP MK2 ensures a constant internal supply voltage even if the battery voltage drops to 6 volts while cranking the engine.
Automatic detection of digital signals
The transition from analog input to digital input is performed automatically as soon as a signal is detected on the optical input. This function can be disabled in the DSP PC-Tool software. Alternatively, an optional remote control can be used to manually switch between analog and digital inputs.
