Axton A894DSP - 6-channel digital amplifier with DSP

Product information Axton A894DSP - 6-channel digital amplifier with DSP

The compact 8.1-channel SMART DSP amplifier A894DSP is the ideal upgrade for many factory-integrated sound systems.

All in to Win

Six high-level inputs and matching optional plug & play cables not only enable connection to standard sound systems, but also to a wide variety of partially and fully active car audio systems.
The high practical suitability of the A894DSP is already evident in the input section: the input channels can be distributed, split or combined to the output channels with complete flexibility.
As a highlight, the music signal can even be linearized using the input equalizer if required.
The extensive BTL modes (bridge operation) offer a flexible choice of output channels, such as 8.0, 6.1, 4.2 or even 4.1 with up to 400 W RMS @ 2 Ohm for the subwoofer.
The individualized signal is conveniently forwarded to a separate subwoofer or center amplifier via the dual mono RCA output or the optical output.
All functions of the DSP settings can be controlled via a single AXTON smartphone app, which is available free of charge for iOS and Android.

Take Control

The integrated digital sound processor enables extensive sound settings for each channel, such as runtime correction, freely configurable frequency filters (6/12/18/24 dB in the three selectable characteristics Butterworth, Bessel and Linkwitz-Riley), gain controls and a parametric 31-band equalizer. The app also includes setups (channel routing and a preset crossover frequency) for each of the optional vehicle-specific plug & Play connection cable.

Bluetooth and more

Your own music collection can be easily streamed to the amp via the integrated Bluetooth audio streaming interface.
The A894DSP also offers the option of playing Hi-Res Audio music data with the separately available ABT50 streaming interface.
Thanks to the optical inputs and outputs, several AXTON DSP amplifiers can be linked together without loss.
A separately available A592DSP-RC remote control can be connected to the A894DSP.
