Axton A544DSP - 4-channel amplifier with DSP

AXTON A544DSP: 4-channel amplifier with 10 DSP channels and 6 preouts, optical input, optical output, linkable power amplifier, equipped with mobile app control, Bluetooth audio streaming, Hi-Res audio optional

The AXTON 4-channel DSP amplifier A544DSP is not only super strong in terms of features, but also in terms of price. An incredible 10 channels can be configured via the integrated digital sound processor. If more DSP channels are required, the audio signal can be transmitted via the optical output to another AXTON DSP amp with an optical input using a fiber optic cable, giving you up to 20 DSP channels - or theoretically an INFINITE number of DSP channels.
Each DSP channel has a parametric 15 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 various input signal sources can be trimmed to a desired frequency response.< br />Channel routing simplifies the assignment of the channels: What was previously done using a cable adapter at the input is now done in the AXTON DSP app, which is available free of charge for iOS and Android smartphones.
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 6 preouts can be routed to an AXTON A601, for example, and you get a powerful amplifier combination with 4 x 25 W RMS + 6 x 100 W RMS, which is suitable for the multi-channel systems of many car manufacturers is applicable.
With the integrated Bluetooth unit, you can easily stream your music collection to the amp.
You can use Hi-Res audio files thanks to the additional optical or coaxial inputs via the car audio system. For this you need the separately available ABT50 interface as an accessory.
AXTON can also supply plug & Play connection cables for over 30 car brands, with which the A544DSP can be easily connected. Thanks to Plug & Play connection, including auto-turn-on function, this power amplifier offers a wide range of possible uses.
A separately available remote control (A592DSP-RC) can be connected to the A544DSP to control the overall level and bass boost to adjust or mute the volume.
