The ABT50 is Axton's Hi-Res audio streaming interface for the A542DSP and A592DSP amplifiers: with this interface you can play Hi-Res audio and regular audio files in your car via Bluetooth.
Simply connect the ABT50 to the A542DSP or A592DSP and you can start enjoying music in the highest resolution.
Hi-Res audio data offers, depending on the format, the highest dynamic content with the resolution of the original "studio master" quality.
Note: If the ABT50 is connected to the DSP amplifier and the music signal is transmitted exclusively via the iPhone OTG cable, the A592DSP-RC remote control is required to control the volume.
