Helix M Six DSP 6 Channel Amplifier 10 Channel Digital Sound Processor 600w RMS

The Helix M Six DSP is a 6-channel Class D car amplifier with a built-in 10-channel 64-bit DSP, delivering 6 x 100 W RMS into 4 or 2 ohms (600 W RMS total). It is part of the Helix M Series, combining amplification and full DSP tuning in a single compact unit.

Key specifications

• Power: 6 x 100 W RMS at 4 and 2 ohm, 3 x 200 W bridged at 4 ohm
• Max output per channel: up to 130 W RMS at 4 / 2 ohm (typical multi-channel use)
• DSP: 64 Bit, 295 MHz, 10 processed channels, 48 kHz sampling
• Inputs: 6 x RCA, 6 x highlevel speaker input, 1 x optical SPDIF (12 to 96 kHz)
• Outputs: 6 x speaker, 4 x RCA (6 V), 2 x remote out
• Highlevel input: ADEP.3 circuit for factory radio integration
• Operating voltage: 10.5 to 16 V (max. 5 sec. down to 6 V)
• Dimensions (H x W x D): 50 x 320 x 154 mm

6 channel Class D amplifier with 10 channel DSP

The M Six DSP is more than a standard six-channel amplifier. Despite its compact dimensions, it functions as a full processing hub with ten processed DSP channels. It delivers 100 W RMS per channel into both 4 ohm and 2 ohm loads. If you need a dedicated subwoofer amplifier alongside it, the Helix M One pairs naturally within the M Series.

ACO: Advanced 32 Bit CoProcessor

The M Six DSP includes a 32 Bit CoProcessor for all monitoring and communication tasks, internally and externally. Compared with the previous 8 Bit generation, this MCU achieves significantly higher speeds for setup switching and data communication with the DSP PC-Tool software. The integrated native boot loader allows software upgrades across all DSP components — useful for adapting the ADEP.3 circuit to future factory radio diagnostic requirements or adding additional interfaces. The ACO also offers 10 memory locations for sound setups, made possible by the onboard flash memory.

Smart highlevel input ADEP.3

Modern factory car radios use sophisticated speaker diagnostics. The latest generation can trigger failure messages or lose features such as fader control when an amplifier is connected. The ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) prevents these issues without placing unnecessary load on the OE radio's speaker outputs at high volumes.

Power Save Mode

Power Save Mode is active by default. It reduces power consumption across all amplifiers connected to the M Six DSP when no input signal is detected for more than 60 seconds. In vehicles with CAN bus or similar systems, the radio may remain active for up to 45 minutes after the car is locked — once Power Save Mode engages, the remote output and any connected amplifiers will switch off. The M Six DSP reactivates the remote output within one second when a music signal is detected. The 60-second turn-off delay can be adjusted or disabled entirely via the DSP PC-Tool software.

Start-Stop capability

The switched power supply in the M Six DSP maintains a constant internal supply voltage even if the battery voltage drops to 6 V during engine crank, ensuring stable operation during start-stop events.
