Alpine, PDP-E802DSP



8-Channel Digital DSP Amplifier

The PDP-E802DSP is the 2nd generation of Alpine's 8-Channel Digital DSP Amplifier . This amazing all-in-one solution allows the sound system to be upgraded to virtually any vehicle as it is extremely versatile and has many connectivity options. It has  6 fish inputs (for both linear and speaker output ) and up to  8 fully configurable outputs  for a very wide and flexible sound system. Tune your sound system with a professional 240-band parametric equalizer, 8-channel Digital Time Delay and 8-channel Digital Crossover.

To configure the system, there is Alpine PC software that connects via WiFi or via USB. Extremely modern and user-friendly software allows full control over all settings and displays these parameters in a user interface with beautiful graphics support. The free Alpine remote control application (available for both Android and iPhone) lets you quickly control the DSP amplifier and has the most necessary features, such as overall volume, subwoofer volume, input selection, presets, and more. The PDP-E802DSP is the best solution for innovating in- vehicle  OEM audio systems , where, for example, it is not so easy / impossible to change the factory radio. The Alpine DSP amplifier easily connects to an existing OEM system, allowing you to create an extremely wide-ranging sound system in your vehicle.

This versatile DSP amplifier now has many enhancements for easier installation and better sound quality. On the software side, it has a new input system with a significantly lower noise level, and an updated pre-output section allows you to connect an additional subwoofer amplifier if needed. There are also now lower signal-to-noise ratios and jumper circuits with color markings and text for easier installation. In addition, many improvements have been made, such as a much more stable Wi-Fi connection, more detailed control of the RUX-KNOB2 subwoofer , as well as a power-dependent power supply system with automatic adjustment. In addition, it has a new automatic output impedance tester that protects the speakers in case of possible incorrect connections.
