By utilizing the USB-C OTG input on the Harmony HB 68 II, you bypass the noise-prone RCA outputs and "dirty" processing of a standard factory radio. A bit-perfect, pure digital signal is fed directly from your mobile device into the 32-bit DSP engine. You get to tune the raw data exactly how you want it before it passes through high-fidelity DAC and is converted into a crystal-clear analog signal for your amplifiers.

Coupled with the HB DSP R-II in-dash controller, you get that "factory head unit" feel with modern precision. From the driver's seat, you can easily manage master volume, sub woofer level, and toggle through your custom DSP presets for different genres of music - all without ever touching the iPad screen.

This combo hits the sweet spot of price vs. performance. Most high-end processors are expensive because they are packed with "OEM integration" features designed to "fix" bad signals from factory radios. You aren't paying for what you don't need. Since your iPad is the source, the signal is already clean, allowing every dollar of your investment to go toward pure, high-resolution processing.

The Harmony DSP may not be the "Top Dog" in the ultra-boutique competition world, but the massive sound quality advantage you gain by streaming Hi-Res audio directly to the DSP gives you a level of clarity, depth, and "black" background silence that even the most expensive processors struggle to achieve when fighting a noisy factory head unit. 

If you want the shortest, cleanest signal path from your iPad to your speakers, the Soundman Pure-Link Kit is the most intelligent way to spend your budget.
