The Axton A544DSP car amplifier combines a 4-channel Class A/B amplifier with a 10-channel digital audio processor and 6 preamp outputs. It can be configured via an iOS or Android app and supports audio streaming with automatic source switching. The optical and coaxial inputs support connection to the ABT50 high-resolution audio interface, available separately.
Each DSP channel has a 15-band parametric equalizer, an active crossover with selectable type and slope, time alignment, phase adjustment and mute. The 9-band input equalizer allows adjustment for each source. The optical output transfers the signal to another Axton DSP amplifier, while automatic turn-on is activated via the high-level input.
