Unlike the typical Class D technology found in similar products, the ZDA4.8 employs Class A/B technology, delivering a warmer, more natural sound that brings your music to life. Even without DSP adjustments, the sound quality is significantly enhanced. However, the built-in DSP takes it further, allowing you to fine-tune your vehicle’s audio system to suit your preferences, no matter your music taste.\nOIS – OEM Impedance Simulation\nThe ZDA4.8 is equipped with OEM Impedance Simulation (OIS), ensuring compatibility with modern head units and amplifiers. By simulating speaker impedance, it maintains the functionality of your vehicle’s OEM head unit, preventing potential issues with installations.\nInput Priority\nThe Input Priority feature ensures effortless integration with your vehicle’s OEM head unit. You can use low-level inputs or digital sources such as Bluetooth, Optical, or Coaxial, without losing vital system sounds like parking sensors, alerts, and radio signals. For instance, if your vehicle has a high-pass filter that limits bass output, you can bypass this limitation by streaming audio directly to the DSP via Bluetooth while maintaining full OEM functionality.\nDSP Outputs\nThe ZDA4.8 doesn’t stop at upgrading your system—it also enables expansion. With four free DSP-configurable RCA outputs (Channels 5-8), you can connect additional amplifiers, such as a subwoofer amp, and fully optimize them using the DSP software. Delay settings, filters, and equalization options ensure top-tier performance for your additional components.\nSoftware\nTake control of your sound system with the free, user-friendly PC software (compatible with Windows 10 and 11). Connect via the included USB-B cable and unlock a suite of powerful tuning tools:\n31-Band Parametric EQ (PEQ) for precise frequency adjustments\nChoose filter types (Bessel, Butterworth, Linkwitz-Riley) with adjustable slopes from -6dB to -48dB.\nTime alignment with a built-in delay calculator\nFully custom channel routing\nCustom link options (Copy or Relate) With these advanced features, you can tune your sound system to your preferences.\nKey Features\nEvery detail of the ZDA Series amplifiers is engineered for excellence:\nBurr Brown OPs – Leveraging the same renowned technology as our ZQ series for superior audio precision.\nBurr DAC PCM1681 – Delivering premium digital-to-analogue conversion for crystal-clear sound.\nBluetooth 5.0 – Seamless wireless connectivity with cutting-edge stability and performance.\nToshiba TDA Transistor Package – Power and efficiency perfectly combined.\nDie-Cast Heatsink – Advanced cooling design for peak performance under pressure.\n48kHz DSP Sampling Rate – Ensuring unmatched clarity and processing accuracy.\nGold PCB Design – A mark of Phoenix Gold’s commitment to quality and durability.\nMolex Connectors – Reliable connections for a worry-free setup.\n8-Channel DSP (All Models) – Unlock unlimited possibilities for customization.\nClass A/B Design – Delivering natural, uncompromised sound without noisy fans.\nHardware Specifications\nType: DSP Amplifier\nAmplifier Class: A/B\nAmplified Channels: 4\nDSP Channels: 8\nFrequency Response (-3dB): 15Hz ~ 23kHz\nMAX Power Rating: 560W\nRMS Power Rating
