Product Overview
The Helix AMPLIFY 206 DSP is a versatile 6-channel Class D amplifier with an integrated 8-channel DSP, combining HELIX DSP expertise with a compact, bridgeable amplifier architecture suited to a wide range of modern vehicle audio configurations. The fully bridgeable design supports 3, 4, 5, or 6-channel operation - from fully active 3-way front systems in 6-channel mode to classic 5-channel layouts with bridged channels 5 and 6 delivering 380W RMS at 4 Ohm to a dedicated subwoofer.
At the core of the DSP section is a 64-bit fixed-point audio DSP running at 295 MHz with BurrBrown 24-bit A/D and AKM 24-bit D/A converters, supported by the ACO (Advanced 32-bit CoProcessor) platform for ultra-fast switching between up to 10 sound setups and advanced features including AISA, TuneEQ, RealCenter, Augmented Bass Processing, DLC, and RTC.
Inputs include 6 x RCA, 6 x high-level with ADEP.3 for OEM integration, and 1 x optical SPDIF (12-96kHz). Outputs include 6 x speaker and 2 x RCA at 8V. No external remote signal is required thanks to the Auto Remote switch. Start-stop compatibility operates down to 6V supply voltage. Full configuration is via DSP PC-Tool 6 software. An SCP (Smart Control Port) is included for connecting remote controls and accessories.
Features & Benefits
Fully Bridgeable 6-Channel Architecture: Supports flexible configuration in 3, 4, 5, or 6-channel operation. Bridged channels deliver up to 380W RMS at 4 Ohm per channel pair, enabling powerful subwoofer drive alongside full front/rear speaker coverage from a single unit.
Integrated 8-Channel HELIX DSP with 64-Bit Processing: The full-featured 8-channel DSP uses a 64-bit fixed-point architecture at 295 MHz with BurrBrown 24-bit A/D and AKM 24-bit D/A converters for precise, high-resolution signal processing, parametric EQ, time alignment, and filter control via DSP PC-Tool 6.
ACO Platform with AISA, TuneEQ, RealCenter and Augmented Bass Processing: The 32-bit ACO CoProcessor enables advanced features including AISA (input signal analysis and correction of factory-processed audio), TuneEQ (automated EQ correction), RealCenter (dynamic centre channel synthesis), Augmented Bass Processing (Dynamic Bass Enhancement and SubXpander), Dynamic Loudness Control, and Remote Tone Control.
ADEP.3 High-Level Input for OEM Integration: The smart 6-channel high-level input with ADEP.3 circuit enables seamless integration into factory OEM sound systems, automatically compensating for factory EQ, boosted signals, and other manufacturer processing in the source signal.
Optical SPDIF Input (12-96kHz): A dedicated optical digital input accepts signals up to 96kHz for lossless digital source integration.
Compact Class D Design with Removable Top Cover: The compact 40 x 263 x 114mm chassis suits installation in tight spaces. A removable top cover conceals all connections and controls for a clean, streamlined installation.
Auto Remote Switch and Start-Stop Capability: The Auto Remote switch activates the amplifier without requiring an external remote signal. Start-stop compatibility maintains operation down to 6V supply voltage for uninterrupted performance.
SCP Smart Control Port: An SCP port enables connection of the HELIX CONDUCTOR PRO and other compatible remote controls and accessories.

Frequently Asked Questions
What channel configurations does the AMPLIFY 206 DSP support?
The fully bridgeable architecture supports 3, 4, 5, and 6-channel operation. In 6-channel mode it suits fully active 3-way front systems. In a classic 5-channel layout, channels 1-4 drive front and rear speakers while bridged channels 5/6 deliver 380W RMS at 4 Ohm to a subwoofer. Three bridged channel pairs each provide 380W for high-power multi-zone setups.
What is ADEP.3 and why is it important for OEM integration?
ADEP.3 is HELIX's smart high-level input circuit that enables clean integration into factory OEM sound systems. It automatically compensates for factory equalisation, boosted output signals, and other processing applied by the vehicle manufacturer, allowing the AMPLIFY 206 DSP to receive a clean, corrected signal without the need for additional signal processors in most OEM integration scenarios.
What DSP features are available on the AMPLIFY 206 DSP?
The integrated 8-channel DSP includes parametric EQ, time alignment, crossover filters, and RTA analysis via DSP PC-Tool 6. The ACO platform adds TuneEQ (automated EQ correction via measurement microphone), AISA (input signal analysis), RealCenter (dynamic centre channel synthesis), Augmented Bass Processing (Dynamic Bass Enhancement and SubXpander), Dynamic Loudness Control, and Remote Tone Control.
Does the AMPLIFY 206 DSP require an external remote signal to turn on?
No. The Auto Remote switch allows the amplifier to activate automatically without requiring an external 12V remote signal from the head unit. This simplifies installation in OEM and aftermarket systems where a remote turn-on wire is not readily available.
Can the AMPLIFY 206 DSP be controlled with the HELIX CONDUCTOR PRO?
Yes. The SCP (Smart Control Port) on the AMPLIFY 206 DSP is compatible with the HELIX CONDUCTOR PRO and other HELIX remote controls and accessories, sold separately.
