AudioWinner DSP46U+ 4 In 6 Out Bluetooth DSP Car Audio Processor

DSP46U+ 4-In 6-Out Car Audio DSP Processor

AudioWinner DSP46U+ is a compact 4-in 6-out car audio DSP processor for upgrading factory and aftermarket audio systems with external amplifiers. Its high-level inputs allow installers to retain the original head unit, while six RCA outputs provide flexible signal routing for multi-channel audio systems.

Bluetooth 5.4, optical input, USB audio and USB disk playback provide multiple source options. Audio tuning is available through PC software and Android or iOS apps, while support for an optional wired controller gives the driver convenient access to volume, source and preset controls.

A Flexible DSP Upgrade Without Replacing the Head Unit

DSP46U+ accepts high-level signals from factory head units and provides six RCA outputs for connection to external amplifiers. It is designed for installers who need flexible signal processing without adding an integrated power amplifier.

Why Choose DSP46U+

• Retain the factory head unit through four high-level inputs

• Connect external amplifiers through six tunable RCA outputs

• Add Bluetooth 5.4, optical and USB audio sources

• Tune EQ, crossover, delay, phase and presets through PC or mobile apps

• Add an optional wired controller for convenient in-car operation

• Install in limited spaces with its compact enclosure

Multiple Audio Inputs and Six RCA Outputs

DSP46U+ supports four high-level inputs, two RCA inputs, optical input, Bluetooth 5.4, USB audio and USB disk playback. Six RCA outputs can be independently configured for different speaker and external-amplifier arrangements.

The REM input and output allow the DSP and connected amplifiers to switch on as part of the same car audio system.

PC, Mobile App and Wired Controller Support

System tuning is available through Windows PC software and Android or iOS apps. Installers can adjust equalization, crossover filters, time alignment, phase, output levels and presets for each audio system.

An optional wired controller provides convenient access to volume, source selection and preset control from the vehicle interior.

Professional Tuning for Different Vehicle Interiors

Every vehicle has different speakers, installation positions and acoustic characteristics. DSP46U+ gives installers the tools needed to balance output levels, correct frequency response and align sound arrival times for a more accurate front soundstage.

DSP46U+ provides the following tuning functions:

• 31-band equalization

• Up to 15 ms time alignment

• Adjustable crossover points from 20 Hz to 20 kHz

• Butterworth, Bessel and Linkwitz-Riley filters

• Filter slopes from 6 to 48 dB/octave

• Adjustable Q value from 0.5 to 9

• EQ gain adjustment from −18 dB to +12 dB

• 0° and 180° phase selection

• Ten user presets

• 24-bit/192kHz ADC and DAC processing

Best For

• Factory head-unit audio upgrades

• Aftermarket head units requiring additional DSP control

• Systems that already use external power amplifiers

• Compact six-channel active or multi-amplifier installations

• Installers evaluating a DSP for regular customer installations

• Distributors and car audio brands evaluating an OEM/ODM DSP platform
