Features

• 4-Pin-XLR+4.4mm 6.35mm output Since then, buying headphones does not have to consider whether the plug matches the headphone amplifier,because the A30Pro already provides you all in a compact body,including 4-PIN XLR,4.4mm,6.35mm.
• SE+BAL input pass through When shutting down, the input signal is directly output to RCA or TRS without amplification, which will be more suitable for active speakers/monitor speakers when the DAC has pre-amplifier functions. Even better is when used with D30Pro, the excellent noise performance of D30Pro is not wasted.
• Say good bye to the ground loops noise When multiple equipment are used, RCA connection may encounter ground loop noise A30Pro introduces a GND/LIFT switch as the solution.
