Interesting, the critique seems to be mainly on the harmonic distortion, the noise looks more acceptable especialy as this is -15dB from full scale. I'm using Yamaha P series amps that have input sensitivity around 8dBu, this is towards the insensitive side. Looking at the Venue 360 manual it states "ANALOG INPUT/OUTPUT CLIP LEVELS [INPUTS: +14, +20, +24, +28 dBu / OUTPUTS: +4, +8, +12, +14, +17, +20, +22 dBu]" so persumably in my circumstance I would use the 8dBu output setting (and I think the most appropriate setting for most users would be the 4dBu setting) so perhaps appropriate to retest at a lower output level setting on the drive rack?
Thanks, this was enlightening. Should probably work fine with lower output settings, then
