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.
