AudioWinner E46.4A 4-in 6-out Class AB DSP Car Amplifier

E46.4A 4-in 6-out Class AB DSP Car Amplifier

The AudioWinner E46.4A combines a six-channel digital signal processor with a four-channel Class AB power amplifier in a compact aluminum chassis.

It provides 4 × 25W RMS at 4Ω or 4 × 50W RMS at 2Ω, with six RCA DSP outputs for connecting external amplifiers or an active subwoofer system.

Class AB Amplification with 6-Channel DSP Output

The E46.4A has four amplified speaker outputs for driving four speakers directly. It also provides six RCA DSP outputs for connecting external amplifiers or an active subwoofer.

This configuration allows installers to build a compact four-channel system and expand it when additional power or output channels are required.

Multiple Audio Input Options

The E46.4A supports:

• 4-channel high-level input

• 2-channel RCA input

• Optical digital input

• Bluetooth 5.4

• USB audio input

• USB flash drive playback

High-level input allows connection to compatible factory head units, while RCA input can be used with aftermarket head units and other low-level audio sources.

Supported USB flash drive formats include MP3, WMA, WAV, M4A, AAC, FLAC and APE.

Cirrus Logic DSP Platform

The E46.4A uses a Cirrus Logic CS47L35 3-core SmartHIFI DSP and a TDA7851 amplifier IC.

Its 24-bit/192kHz ADC and DAC provide the processing platform required for multi-channel car audio tuning.

PC and Mobile DSP Tuning

The E46.4A can be configured through AudioWinner PC software, Android app or iOS app.

Available DSP functions include:

• 31-band equalization

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

• Adjustable Q value from 0.5 to 9

• High-pass and low-pass crossover control

• Butterworth, Bessel and Linkwitz-Riley filters

• Crossover slopes from 6dB/octave to 48dB/octave

• Time alignment up to 15ms

• 0°/180° phase selection

• 10 preset memories

A compatible DSD or LED wired controller is available separately for convenient in-vehicle control.

Factory and Aftermarket System Integration

The E46.4A accepts both high-level speaker signals and low-level RCA signals, making it suitable for compatible factory and aftermarket audio systems.

A universal aftermarket wiring harness is included. Vehicle-specific plug-and-play harnesses are available separately.
