HIFI-X12 8-Channel Car Amplifier with 10-Channel DSP and HD APTX Media Player

Overview: The HIFI-X12 integrates an HD APTX media player, an 8-channel power amplifier and a 10-channel digital signal processor into a compact module designed to simplify and elevate in-car audio. Each amplifier uses advanced switching amplifier technology with real-time monitoring and correction of switching errors, dynamic output filter adjustment, and time-aligned correction/amplification to deliver smooth, detailed and natural-sounding output. Power & Amplifier Configuration: - 8-channel car amplifier with 10-channel digital signal processing - CH1~CH6: up to 75 watts per channel into 4 ohms, or 100 watts into 2 ohms; Class AB; THD < 1%. - CH7~CH8: up to 125 watts per channel into 4 ohms, or 190 watts into 2 ohms; Class D; THD < 1%. - Bridged mode (into 4 ohms) yields up to 250 watts into 4 ohms or 380 watts into 2 ohms. Digital Signal Processing (DSP): - 10-channel DSP using 2 dual-core high-end hi-res audio processing chips with computing power up to 456 MHz. - DSP Processor: OMAP 2 x 456 MHz, 32 Bit (till 64-bit/IEEE double precision). - DSP processing modes: Fixed & Floating. DSP sampling rate: 96 KHz. - Built-in flexible audio routing matrix to route all inputs/outputs with high flexibility and sync parameter loading to maintain filter stability. ADC / DAC, Noise & Dynamic Specs: - ADC Processor / DAC Processor: 64 Bit, 784 KHz, 115 dB DNR~132 dB DNR (*10ch). - Frequency response: 5Hz @ 45 KHz. - THD+N: 0,0008 (Digital Input), 0,001 (Analog Input). - 1V Out S/N Device Floor Noise: -125 dB (from 20 Hz to 20 KHz), -135 dB (from 150 Hz to 20 KHz), -140 dB (average from 80 Hz to 20 KHz). - S/N Ratio (Digital Inputs): from 115 to 120 dB A. - S/N Ratio (Analog Inputs): from 109 to 115 dB A. - Crosstalk: > 110 dB (from 300 Hz to 0.9 KHz); average 115 dB (from 300 Hz to 0.9 KHz). Tuning & Adjustment Features: - 10-channel OMAP 2 x 456 MHz, 32 Bit (till 64-bit/IEEE double precision) digital processor. - 31-band EQ with fine tuning. - Adjustable high-pass, low-pass and band-pass filters covering 20-20 KHz. - Selectable filter slopes: 6, 12, 18, 24, 30, 36, 42, 48 dB/octave. - Delay: 0-20 milliseconds (0-273"). - Phase: 0° or 180° selection. - DSP configuration and real-time adjustment via Windows PC over USB. Additional Details: - The DSP allows compensation for speaker, amplifier and acoustic environment limits through speaker EQ, multiband compression, clipping and AE algorithms to improve perceived sound quality. - Optional wired LCD remote control (sold separately). - Remote dimensions: 95mm * 70mm * 15mm. - DSP unit dimensions: 305mm * 180mm * 55mm.
