With a 192kHz sampling rate, the BOYA BY-AM4 captures high-resolution audio for desktop and mobile setups. Two combo inputs handle XLR or 1/4" signals for simultaneous vocal and instrument tracking. USB-C bus power keeps the interface running without external power bricks.
The unit includes a 48V switch for the XLR combo inputs. This supplies the necessary current for high-end studio condenser microphones.
Connection via the USB-C port works with most Android devices supporting OTG. High-power microphones might require an external power source to maintain signal stability.
