    About this item

    • ULTIMATE HI-FI UPGRADE (ESS QUAD DAC & TI OP-AMP)

      Unlike generic receivers, SLASH 4 features the flagship ESS ES9219 Quad DAC and Texas Instruments OPA1692 OP-AMP. It transforms standard car audio and home stereos into professional-grade systems, delivering 24-bit/96kHz Hi-Res sound with an industry-leading 130dB SNR.

    • ELIMINATE NOISE (BUILT-IN GROUND LOOP ISOLATOR)

      Stop suffering from alternator whine and electrical power noise. Our advanced LDO regulator and isolation technology physically block ground loop interference, ensuring a pitch-black, silent background. This is critical for high-end car audio builds and commercial environments with complex power setups.

    • TOP-TIER HI-RES WIRELESS (SONY LDAC & aptX ADAPTIVE)

      Powered by the Qualcomm QCC5125 chipset, SLASH 4 supports Sony LDAC (990kbps), aptX Adaptive, and aptX HD. The deliberate single-device pairing design ensures maximum bandwidth and 100% signal stability for lossless, studio-quality streaming.

    • VERSATILE PRO OUTPUT (OPTICAL, AUX & HEADPHONE AMP)

      The unique 3.5mm multi-port serves three roles: Analog AUX for vehicles, Digital Optical for home/DSP amplifiers, and a high-performance Headphone Amp. This versatile interface makes it an essential tool for car audio installers and commercial BGM setups.

    • 24/7 B2B RELIABILITY (HEAT-RESISTANT & MADE IN KOREA)

      100% Designed and Manufactured in South Korea for demanding 24/7 continuous operation. Engineered with a robust Navy-finished metal housing, it operates reliably even in extreme temperatures from hot vehicle interiors to enclosed equipment racks.

    • PLUG-AND-PLAY CONVENIENCE & SPECIFICATIONS
