HELIX M SIX DSP

6 Channel Class D Amplifier

HELIX M SIX DSP

That rocks – the new M SIX DSP

The M SIX DSP is more than “just” another six-channel amplifier – rather, despite its small dimensions, you are dealing with a powerful control center that has not less than a total of ten processed DSP channels. In addition, the amplifier delivers plentiful output power with generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load. 

Finally its awesome price performance ratio in combination with the fantastic feature set will ensure bright eyes.

Features

• Up to 130 Watts RMS max. output power per channel into 4 & 2 Ω
• Extremely powerful 64 Bit “fixed point” Audio DSP and state-of-the-art AD and DA signal converters
• ACO – Advanced 32 Bit CoProcessor platform for enhanced system and DSP features like:
• ISA (Input Signal Analyzer) and InputEQ for easy analysis and compensation of input signals
• SFX sound effects – Augmented Bass Processing, StageXpander, RealCenter & Co.
• Smart 6-channel highlevel input with ADEP.3 circuit
• Four RCA / Cinch line outputs with max. 6 Volts output voltage
• Virtual Channel Processing (VCP) allows even more flexible configuration for highly complex sound systems
• Bridgeable amplifier channels for driving powerful woofer or subwoofer
• DSP-board manufactured in Germany

ACO – Advanced 32 Bit CoProcessor

The HELIX M SIX DSP 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.

It 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.

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 an amplifier will be hooked up – but not with the M SIX DSP.

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.

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 M SIX DSP 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 M SIX DSP 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.

Start-Stop capability

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