Our carefully manufactured ATS-ISO connection cables are a perfect fit for over 400 vehicle models from over 30 vehicle brands. Use our configurator on our homepage to find the right connection cable for your car. If you are unsure, our support team will be happy to help you.

The high practicality of the A544DSP is already evident in the input section: the input channels can be distributed, split or merged to the output channels with complete flexibility: For example, combine a high-frequency and a low-frequency input signal to form a full-range output signal or, if only two radio outputs are available, distribute the signal to all amplifier outputs. As a highlight, the music signal can even be linearized using the input equalizer if required.

Want to know exactly how it works? We explain the function in detail in our video.

The integrated digital sound processor enables extensive sound settings per channel, such as delay time correction, freely configurable frequency filters (6/12/18/24 dB in the three selectable characteristics Butterworth, Bessel and Linkwitz-Riley), gain control and a parametric 15-band equalizer.

The highlights

• Freely adjustable active crossover: High/low/band/bypass with 6/12/18/24 dB/oct. slope per channel (Butterworth, Bessel or Linkwitz-Riley)
• Freely adjustable 15-band parametric equalizer per channel
• Freely adjustable 9-band parametric equalizer per input source
• Gain, phase switch and mute function per channel
• Adjustable delay correction per channel (0 - 550 cm / 0 - 15.8 ms)
• Memory locations for your own settings: 5 on the amplifier, unlimited on the smartphone
• Dynamic Bass function for powerful performance without a subwoofer
• Noise gate function to reduce the background noise of the radio

Controller app

The integrated Class A/B amplifier drives 4 output channels with 4 x 25 W RMS. This is enough power for a noticeable boost of the standard loudspeakers and a sonorous drive for tweeters in 2-way or 3-way concepts. The other 6 pre-outs can be conveniently routed to an AXTON A601 and you get a powerful amplifier combination with 4 x 25 W RMS + 6 x 100 W RMS (or 3 x 320 W RMS bridged) - enough power for your car audio project!

You can find all the information about the A601 here.

An incredible 10 channels can be configured with the new A544DSP via app. If you need even more DSP channels, you can transmit the audio signal loss-free via the optical output to another AXTON DSP amplifier with an optical input, giving you up to 20 DSP channels. With this concept, it is theoretically even possible to create an INFINITE number of DSP channels.

The DSP amplifiers have an optical input and an optical output:

• A544DSP
• A594DSP
• A894DSP

The integrated Bluetooth audio streaming interface makes it easy to stream your own music collection to the amp. The A544DSP 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. The A592DSP-RC remote control (available separately) can be connected to the A544DSP.
