Special features:

TwinDSP Power

The DSP PRO MK3 contains two of the most powerful 64 Bit audio signal processors from Analog Devices with the outstanding overall calculating power of 2.4 billion MAC operations per second.
The TwinDSP Power concept makes the twelve separately processed channels and the numerous new sound features in combination with the extended sampling rate of 96 kHz (resulting in an audio bandwidth of more than 40 kHz) possible.

ACO – Advanced 32 Bit CoProcessor

The HELIX DSP PRO MK3 incorporates an extraordinary powerful 32 Bit CoProcessor of the latest generation. This not only takes over all control tasks ultra-fast, but also the lightning-fast switching between up to ten possible sound setups. But ACO offers much more – besides a channel-separated Input EQ including Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios and fantastic sound effects like Augmented Bass Processing or RealCenter, there is now the revolutionary TuneEQ function for automated adjustment of the output equalizers.
A further significant advantage is the integrated, native boot loader of the CoProcessor. It allows software upgrades of all components of the DSP in order to adjust the microcontroller-controlled ADEP.3 circuit for example at future modifications / changes in the diagnostic system of factory radios or if the device will be extended with additional interfaces.

Smart highlevel input ADEP.3

Modern, 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 a signal processor will be hooked up – but not with the DSP PRO MK3.
The 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.

Start-Stop capability

The switched power supply of the HELIX DSP PRO MK3 assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.

Power Save Mode

The 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 DSP PRO MK3 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. The ­HELIX DSP PRO MK3 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.

Automatic Digital Signal Detection

Switching from analog 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 analog and digital inputs.
