Technical Specifications Review: Good product - Haven’t figured it out yet but it connects easily and works. Review: Great little DSP - Aside from the input being glitchy and unusable when the remote volume nob is installed, this is a great little DSP. Other reviewers have expressed displeasure over not being able to control the programming via Bluetooth, but it's really not that difficult to set up once you get familiar with the controls. I use this via a 'wall wart' 12v power supply to play music through pro audio amps in my garage. It syncs with my phone quickly, and provides crossovers and routing to 4 high channels and a sub. ## Features - Advanced Audio Customization: Elevate your sound system with the NVX XDSP28, featuring a 15 Band Parametric EQ and a rotating control knob for easy access to all menu functions and settings. Fine-tune your audio with fully adjustable high and low-pass filters and a variety of crossover types and filter slopes. - Seamless Integration: Designed for aftermarket audio systems, this DSP offers 2 RCA inputs and 8 RCA outputs with up to 2 Volts of output. Enjoy crystal-clear audio with a signal-to-noise ratio of over 94 dB and a total harmonic distortion of just 0.01%. - Precision and Flexibility: Achieve perfect sound alignment with time adjustments in 0.02 ms increments and phase adjustments of 0 or 180Β°. Choose from 12 graphic equalization presets to suit your music style, including Rock, Hip Hop, Pop, Vocal, and more. - Enhanced User Experience: The NVX XDSP28 features an integrated audio tone generator with frequency sweep and pink noise for precise tuning.
