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 Goodbye to Ground Loops Noise
When multiple equipment are used, RCA Connection may encounter ground loop noise. A30 Pro introduces a GND/LIFT switch as the solution. When in normal use, set it to GND; when encountering ground loop noise, switch to LIFT to change the ground point of the A30PRO from the it’s chassis to other equipment which it connected to.
