Monitor level

Using a RME HDSP Digiface SPDIF out -> MAudio SuperDAC -> yamaha hs50 monitors

The hs50 level are to be adjusted at their back, which snap into place aa middle position of +4db, which is quite loud :wink:

How am I supposed to adjust the monitoring level?

  1. leaving the hs50 level at their snapped position, adjusting monitoring level with the HDSP out level
  2. adjusting the hs50 levels, trying to adjust left and right at the same levels, which is quite cumbersome as they only snap into place @ +4db

I use something like this>

Or use the control room in C6 but a real volume knob is much better.
