Pioneering Audio Processing with Remote Level Control

The XDSP28 stands out as the first of its kind in the automotive car audio market with a Remote Level Controller, enabling simultaneous control of all eight outputs. This feature, combined with its advanced capabilities for filters, graphic and parametric equalization, alignment, phase inversion, limiter, and an audio generator, makes it a revolutionary tool for enhancing automotive audio systems.

User-Friendly Interface and Versatile Connectivity

Featuring an intuitive interface with an LCD display for real-time audio adjustments. It comes equipped with 2 audio inputs (A and B) and 8 independent outputs, allowing users to select the audio source for each output. This flexibility is essential for customizing audio according to individual preferences or specific vehicle needs.

Sophisticated Equalization System

The XDSP28 boasts a comprehensive equalization system, including a 15-band graphic equalizer with manual tuning and 12 presets for various genres. Additionally, it offers 1 INPUT and 1 OUTPUT Parametric Equalizers for professional-grade adjustments, providing users with detailed control over frequency, gain, and bandwidth.

Advanced Crossover and Limiter Functions

This audio processor features a precise Crossover function with customizable frequencies, attenuation rates, and filter types (Butterworth and Linkwitz-Riley). The Limiter, with its Dynamic Attack-Release system, helps protect amplifiers and speakers by dynamically adjusting the Attack and Release parameters, ensuring both security and high sound fidelity.

Comprehensive Audio Treatment and Configuration Features

The XDSP28 excels in audio treatment with functions like High Accuracy Delay, Phase Inversion, Independent Gain by Output, and Master Level. Additionally, it has an integrated Audio Generator for accurate measurements, a Configuration Copy function for output channels, and various management features like Save and Load Settings, Security Password, Marquee/Text Display, and multi-language support (English, Spanish, Portuguese).

Frequently Asked Questions (FAQ)


Check if the Bluetooth mode is active; if it's on, the RCA inputs are automatically muted. Also, ensure the "Remote Level Controller" isn't turned all the way down, as it controls all 8 outputs simultaneously.
Ensure the Bluetooth antenna is pointed up and not obstructed by metal. If pairing fails, long-press the volume button for 5 seconds to clear previous memory. For the best wireless experience, always use NVX high-quality interconnects.
This is likely a ground loop. Ensure the NVX XDSP28 ground wire (16 AWG recommended) is secured to a bare metal chassis point. Avoid routing input signal cables next to power wires to prevent electromagnetic interference.
Use the built-in "Limiter" function to set dynamic attack/release parameters. This protects your gear from signal spikes. For maximum protection and clarity, pair this unit with NVX V-Series amplifiers for a matched, clean signal path.
Verify the "REM IN" wire has a solid +12V signal from your head unit. If the XDSP28 stays on but amps don't, check that your total remote turn-on load doesn't exceed the output limit; you may need an NVX power relay for multiple amps.

Great crossover, for the most part

Control knob very sensitive. Remote control of adjustments would be nice whether through an app or even a port to connect a tablet or laptop.
