Impact ISM 400.2DSP

"Slot in" upgrade amplifier module

2-channel amplified subwoofer module with 1-channel DSP for high-quality subwoofer upgrades in modern vehicles, delivering powerful yet controlled bass:

Ideal for targeted subwoofer upgrades in factory-installed sound systems thanks to integrated DSP and high power stereo highlevel input with up to 32 V RMS input sensitivity
Direct upgrade of passive 2 x 2 Ω IMPACT enclosure subwoofers by simply replacing the subwoofer connection terminal
Perfect starting point for custom-made active subwoofer solutions

Up to 460 W RMS output power at 2 x 2 Ω for driving powerful subwoofers
Start-Stop capable power supply with an extended input voltage range up to 18 V – ideal for modern electric vehicles
Very compact design with low heat dissipation thanks to extraordinary efficiency
Extremely powerful 64 Bit “fixed-point” Audio DSP and high-quality AD / DA converters for clean signal processing and maximum bass performance
Smart highlevel input with ADEP.3 for trouble-free integration into OEM sound systems
Additional auto turn-on via music signal for maximum compatibility with factory sound systems
ACO – Advanced 32 Bit CoProcessor platform for system an
AISA (Advanced Input Signal Analyzer) and InputEQ AISA (Advanced Input Signal Analyzer) and InputEQ for easy analysis and correction of input signals
DLC (Dynamic Loudness Control) and RTC (Remote Tone Control) for volume-dependent dynamic adjustment of highs and lows
Proprietary TuneEQ function for automated adjustment of the input, virtual and output equalizers
Augmented Bass Processing
Compact, future-proof SCP (Smart Control Port) for connecting remote controls and accessories
DirectDSP function – the input signal is routed unprocessed and unfiltered directly to the output stage of the amplifier
Maximum control with DSP PC-Tool 6 – professional software for precise configuration and accurate sound tuning in the vehicle, including presets for IMPACT enclosure subwoofers
