    Aventidis Greece –

    More control than I expected at this price point

    Been running a hybrid setup with a Focusrite and a handful of synths and this box ticked every box I didn't know I needed. The per-channel mute switches are the standout feature for me — being able to cut individual inputs without touching the DAW is a proper workflow improvment, especialy during a session when you're A/B-ing elements quickly.
    Out A / Out B switching is also genuinly useful. Monitors in one room, recording chain in another — flip the switch, done. No extra patchbay needed.
    STM on the mono inputs keeps kick and bass centered and tight, variable headroom switch lets you dial in how hard you're pushing the passive summing circuit. The sound improvement over going strait into the interface is real — more depth, better stereo seperation, transients feel more controlled.
    VISHAY DALE resistors, point-to-point hand wired, laser engraved aluminium. For the price it's remarkable build quality. 12 days as stated. Recomend.
