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 - AXTON's compact 4-channel A592DSP amplifier allows you to enjoy 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.

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. Box contents: 1 x DSP amplifier, 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.

The integrated crossover, adjustable from 20 Hz - 20 kHz, selectable slope slope 6, 12, 18, 24 dB/oct., ensures that the connected speakers only reproduce the frequency component specified for them.
The EA-D8 is designed as a pure 8-channel sound processor without integrated amplifier and the ideal interface between factory or retrofit radio and individual amplifier concept. The EA-D8 offers enough channels for a full-blown car audio system and allows numerous settings.
The DSP settings can be easily controlled via the smartphone. The necessary app is available free of charge on the EMPHASER homepage or in the app stores. In addition, there is the possibility of direct Bluetooth audio streaming from smartphone to EA-D8. The switch between radio and mobile phone playback is completely automatic. The settings made can be saved on the batch processor or on the mobile phone.
Other features include: gain control, phase shift, mute as well as the noise-gate function, which removes noise or whistles. The EA-D8 has a high-level input with auto-turn-on function and can be easily connected via the enclosed plug or with optional vehicle-specific Plug & Play cables.
A special feature of the EA-D8 is the channel management: each output can be assigned one or more input signals. This also includes the fusion of one tweeter and low frequency input signal into a complete output signal. This summing function is especially necessary for various original premium sound systems.
