The Pro Output has individual 3.5mm inputs for left and right, the left one being normalized to the right one. Unlike other output modules it clips at 23Vpp so it has lots of headroom.
A stereo 3.5mm output socket with -10dbV is available. The adjustable line- and headphone-output is stereo and has both 3.5mm and 6.53mm outputs. The output level is internally limited to -10dBV but it can be deactvated by jumper so you can get full +4dBu at those outputs. The sound quality remains the same, whether with or wihout limiter.
Two 6.35mm mono outputs for left and right are balanced, have a maximal level of +4dBu and a low impedance to drive long cables.
