With 8 x 110W RMS into 4 ohms and 4 x 220W RMS into 2 ohms on channels 5–8, it provides a flexible foundation for demanding multi-channel speaker upgrades.\u003c\/p\u003e\u003cp\u003eTwelve high-level inputs, six RCA inputs, optical SPDIF and USB PerfectStream support factory-system integration, aftermarket sources and direct digital audio connections. Six processed RCA outputs allow additional amplifiers to be added, extending the system beyond the eight internally amplified channels.\u003c\/p\u003e\u003ch3\u003eDSP PC-Tool 6 and advanced tuning\u003c\/h3\u003e\u003cp\u003eThe 64-bit DSP and 32-bit ACO coprocessor support precise configuration through DSP PC-Tool 6. Virtual Channel Processing provides cross-channel group equalisers, flexible multi-way speaker configurations and Rear Attenuation. The Advanced Input Signal Analyzer and Input EQ help analyse and compensate for factory-source processing, while TuneEQ provides automated equaliser adjustment using a suitable measurement microphone, available separately.\u003c\/p\u003e\u003cp\u003eSound-processing options include RealCenter, Augmented Bass Processing, Dynamic Loudness Control and Remote Tone Control. ACO supports fast switching between up to ten sound setups, making the amplifier adaptable to different listening preferences.\u003c\/p\u003e\u003ch3\u003eUSB PerfectStream and expandable connectivity\u003c\/h3\u003e\u003cp\u003eThe bidirectional USB PerfectStream interface combines lossless audio streaming, AISA measurement-signal transmission and simultaneous DSP configuration through USB-C. It accepts audio streams up to 192kHz\/32-bit; the internal DSP operates at a 48kHz sampling rate. Individual DSP-channel audio can also be returned to a computer for analysis.\u003c\/p\u003e\u003cp\u003eThe Extension Card 2.0 slot supports optional expansion modules for functions such as Bluetooth HD streaming and additional inputs. A Smart Control Port connects compatible optional remote controls and accessories. Expansion cards, remote controls and measurement equipment are not included.\u003c\/p\u003e\u003ch3\u003eIntegration and efficient power delivery\u003c\/h3\u003e\u003cp\u003eThe 12-channel high-level input accepts up to 32V RMS and incorporates ADEP.3 circuitry to support integration with modern factory-radio speaker diagnostics. Input-to-Output Routing allows high-level inputs to be individually assigned to amplifier or line outputs. Class HD amplification combines Class H supply-voltage control with Class D amplification to reduce losses, while SOP Max stabilises output power as the vehicle supply voltage changes.\u003c\/p\u003e\u003cp\u003eThe start-stop-capable power supply supports brief voltage drops to 6V. Auto Remote switching allows activation without a separate external remote signal, and configurable Power Save Mode switches off the internal amplifier stages and remote output after a period without music, returning to normal operation when a signal is detected.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEight amplified channels and 14 processed DSP channels.\u003c\/li\u003e\n\u003cli\u003eSix processed RCA outputs for expansion with external amplifiers.\u003c\/li\u003e\n\u003cli\u003eTwelve high-level inputs with ADEP.3 diagnostic protection.\u003c\/li\u003e\n\u003cli\u003eSix RCA inputs and an optical SPDIF input.\u003c\/li\u003e\n\u003cli\u003eUSB PerfectStream audio, measurement and configuration via USB-C.\u003c\/li\u003e\n\u003cli\u003e64-bit audio DSP and 32-bit ACO coprocessor.\u003c\/li\u003e\n\u003cli\u003eVirtual Channel Processing, AISA, Input EQ and TuneEQ.\u003c\/li\u003e\n\u003cli\u003eRealCenter, Augmented Bass Processing, Dynamic Loudness Control and Remote Tone Control.\u003c\/li\u003e\n\u003cli\u003eExtension Card 2.0 slot and Smart Control Port.\u003c\/li\u003e\n\u003cli\u003eSOP Max stabilised output power, Auto Remote and start-stop capability.\u003c\/li\u003e\n\u003cli\u003eConfiguration through DSP PC-Tool 6.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAmplifier technology: Class HD.\u003c\/li\u003e\n\u003cli\u003eRMS power at ≤1% THD+N, 4 ohms: channels 1–8, 8 x 110W.\u003c\/li\u003e\n\u003cli\u003eRMS power at ≤1% THD+N, 2 ohms: channels 5–8, 4 x 220W.\u003c\/li\u003e\n\u003cli\u003eMaximum output in typical multi-channel applications: up to 140W RMS per channel at 4 ohms on channels 1–8; up to 270W RMS per channel at 2 ohms on channels 5–8.\u003c\/li\u003e\n\u003cli\u003eInputs: 6 x RCA, 12 x high-level speaker inputs, 1 x optical SPDIF (12–96kHz), 1 x Extension Card 2.0 slot and 1 x USB PerfectStream.\u003c\/li\u003e\n\u003cli\u003eRCA input sensitivity: 1–8V.\u003c\/li\u003e\n\u003cli\u003eHigh-level input sensitivity: 4–32V.\u003c\/li\u003e\n\u003cli\u003eRCA input impedance: 25kΩ.\u003c\/li\u003e\n\u003cli\u003eHigh-level input impedance: 9–33Ω with ADEP.3.\u003c\/li\u003e\n\u003cli\u003eOutputs: 8 x speaker, 6 x RCA and 2 x remote outputs.\u003c\/li\u003e\n\u003cli\u003eRCA output voltage: 3V.\u003c\/li\u003e\n\u003cli\u003eFrequency response: 15Hz–22,000Hz.\u003c\/li\u003e\n\u003cli\u003eDSP resolution: 64-bit.\u003c\/li\u003e\n\u003cli\u003eDSP power: 295MHz, 1.2 billion MAC operations per second.\u003c\/li\u003e\n\u003cli\u003eInternal DSP sampling rate: 48kHz.\u003c\/li\u003e\n\u003cli\u003eA\/D and D\/A converters: BurrBrown, 24-bit.\u003c\/li\u003e\n\u003cli\u003eA-weighted signal-to-noise ratio: 107dB digital input; 102dB analogue input.\u003c\/li\u003e\n\u003cli\u003eTHD at 1kHz, 1W into 4 ohms: \u0026lt;0.007%.\u003c\/li\u003e\n\u003cli\u003eTHD+N at 1kHz, 1W into 4 ohms: \u0026lt;0.009%.\u003c\/li\u003e\n\u003cli\u003eDamping factor: 100.\u003c\/li\u003e\n\u003cli\u003eOperating voltage: 10.5–18V, with drops to 6V supported for a maximum of 5 seconds.\u003c\/li\u003e\n\u003cli\u003ePower rating: DC 12V, 110A maximum.\u003c\/li\u003e\n\u003cli\u003eIdle current: 750mA.\u003c\/li\u003e\n\u003cli\u003eMaximum remote output current: 500mA.\u003c\/li\u003e\n\u003cli\u003eFuses: 2 x 40A LP-Mini (APS).\u003c\/li\u003e\n\u003cli\u003eOperating temperature: -40°C to +70°C.\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D): 44 x 220 x 180mm.\u003c\/li\u003e\n\u003cli\u003eManufacturer model code: HA18207.\u003c\/li\u003e\n\u003cli\u003eEAN: 4057204315948.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation notes\u003c\/h3\u003e\u003cp\u003eThe 14-channel DSP does not mean 14 amplified speaker channels: eight channels are amplified internally and six additional processed line outputs are provided for system expansion. 2-ohm operation is specified for channels 5–8 only; 1-ohm and bridged operation are not specified by the manufacturer.
