The integrated digital sound processor allows extensive sound settings per 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. Integrated in the app are also setups (channel routing and a preset of the cut-off frequencies) for each of the optional vehicle-specific plug & play connection cables.
The integrated Bluetooth audio streaming interface allows you to easily stream your own music collection to the amp. The A894DSP also offers the ability to play Hi-Res Audio music data with the separately available streaming interface ABT50 (ASIN B08LPNTHKQ). Thanks to the optical inputs and outputs, several AXTON DSP amplifiers can be connected to each other without loss. The A894DSP can be connected to a separately available remote control (ASIN B08MFFSZ7L).
The extensive BTL modes (bridge operation) offer flexible choice of output channels, such as 8.0, 6.1, 4.2 or even 4.1 with up to 400W RMS @ 2 ohms for the subwoofer. The dual mono RCA output or the optical output allows the individual signal to be conveniently forwarded to a separate subwoofer or centre amplifier. 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.
The compact 8.1-channel SMART DSP amplifier A894DSP is the ideal upgrade for many factory-integrated sound systems. Six high-level inputs and matching optional Plug & Play cables allow you to connect to standard sound systems as well as to various partially and fully active car audio systems. The input channels can be distributed, split or merged completely flexibly to the output channels. The music signal can even be linearised via input equalizer.
Technical Data - RMS output powers @ 4Ω: 8 x 60W, @2Ω: 8 x 75W, in BTL4.2 mode CH 5+6 / CH7+8 @ 4Ω: 2 x 230W, in BTL4.1 mode CH 5+6+CH7+8 @ 4Ω: 1x 230 W, In BTL4.1 mode CH 5+6+CH7+8 @ 2 Ω: 1 x 400 W, playback range: 20 Hz ~ 20 kHz, dimensions (L x W x H): 238 x 180 x 50 mm · Box contents: A894DSP, 24 pin main connection cable, 8 pin connection cable for 8 pin .0 mode, 8 pin connection cable for 6.1 mode, 8 pin connection cable for 4.2 mode, 8 pin connection cable for 4.1 mode

Main highlights

With the integrated Bluetooth unit, you can easily stream your music collection to the amp. You can also play Hi-Res audio files via the car audio system thanks to the additional optical or coaxial inputs. For this purpose, you need the separately available interface ABT50 (ASIN B08LPNTHKQ) as an accessory. Plug & Play connection cables are available from AXTON for over 30 car brands, with which the A594DSP can be easily closed.
The integrated Class D amplifier fires 4 output channels with up to 4 x 50 W RMS. The A594DSP has a stereo preout for the subwoofer channels, so underseat, footwell or kick bass can be adjusted separately in 3-way systems.
The AXTON 4-channel DSP amplifier A594DSP is not only super strong in terms of equipment, but also at price. 6 channels can be configured via the integrated digital sound processor. If more DSP channels are needed, the audio signal is transmitted via the optical output via fibre optic cable to another AXTON DSP amp with optical input. With this concept, it is possible to generate infinitely many DSP channels.
Thanks to plug & play connection, including auto-turn-on function, this power amplifier offers a wide range of uses. The A594DSP can be connected to a remote control (ASIN B08MFFSZ7L) to adjust the overall level and bass boost or mute the volume. Available as accessories: mounting bracket N-A544DSP-FIX01, compatible with Fiat Ducato (ASIN B0FS7RNV4H) · Box contents: A594DSP, 1 x Bluetooth antenna · Dimensions (L x W x H): 218 x 114 x 40 mm
Each DSP channel has a parametric 31 band EQ, crossovers up to 24 dB/Oct. (Butterworth, Linkwitz or Bessel), runtime correction and phase correction. With the 9-band INPUT EQ, possible differences in the frequency response of the different input signal sources can be trimmed to a desired frequency response. Channel routing simplifies channel assignment. All settings are done via the AXTON DSP app, which is available free of charge for iOS and Android smartphones.

Plug & Play connection cables for over 30 car brands are also available from AXTON with which the A544DSP can be easily closed.
The integrated Class A/B amplifier fires 4 output channels with 4 x 25 W RMS – enough power for a noticeable boost of the series speakers and a sonorous drive for the tweeters in 2-way or 3-way concepts. The other 6 preouts can be forwarded e.g. to a AXTON A601 (ASIN B08RZ3MDQ2), and you get a powerful amplifier combination with 4 x 25 W RMS + 6 x 100 W RMS, which is applicable to the multi-channel systems of many car manufacturers.
The AXTON 4-channel DSP amplifier A544DSP is not only super strong in terms of equipment, but also at price. Incredible 10 channels can be configured via the integrated digital sound processor. If more DSP channels are needed, the audio signal is transmitted via the optical output via fibre optic cable to another AXTON DSP amp with optical input and thus receive up to 20 DSP channels – or theoretically infinite DSP channels.

Main highlights

The digital sound processor has useful tools such as: runtime correction, freely configurable frequency filters (6/12/18/24 dB), gain control per channel, a freely configurable parametric 31-band equalizer per channel or 5-band EQ for the subwoofer channel.
The DSP is controlled via Bluetooth via an app, which is available free of charge for iOS and Android smartphones. With this app, all functions are clearly displayed, so that even newcomers can make the DSP settings without prior knowledge. The settings can be saved on the power amplifier or on the mobile phone.
The A592DSP can be connected to a remote control (ASIN B08MFFSZ7L) to adjust the overall level and bass boost or mute the volume. This control function is particularly interesting when the power amplifier is operated "stand-alone", i.e. without radio. Thanks to plug & play connection, including auto-turn-on function, and the integrated 5-channel DSP-controlled preamp outputs, this 2-ohm stable power amplifier offers a wide range of applications.
Included components: 1 x amplifier, 1 x ISO connection cable, 1 x Bluetooth antenna, 1 x user manual (English language not guaranteed)
Ideal upgrade for factory installations - The compact 4-channel A592DSP amplifier from AXTON gives you extensive sound settings via the integrated digital sound processor. The built-in Bluetooth interface allows you to easily stream your own music collection to the amp. Just pair your smartphone with the amp, press play - and your phone's music collection is available wirelessly in your car, motorhome or truck, even if the radio does not have the appropriate interfaces.
Hi-Res audio files can be played back via the car audio system thanks to the additional optical or coaxial inputs. You need the separately available streaming interface ABT50 (ASIN B08LPNTHKQ) as an accessory: simply plug it into the amplifier and enjoy your favourite music in original studio master quality.
