The UR824’s front panel hosts two Neutrik combo TRS/XLR connectors for balanced microphone/line input with switchable 48 volt phantom power and Hi-Z, pad push buttons for signal attenuation, gain controls with peak indicators. On the opposite side there’s a single output level rotary knob that allows you to easily adjust the levels of the eight line output signals alongside two headphone connectors, each with a dedicated level control. The output signal to be controlled by the front panel rotary is selected through the software.
