41.2 Connector Pinouts
TRS jacks of analog input / output
The stereo 1/4" TRS jacks of the rear analog inputs and outputs are wired according to interna-
tional standards:
Tip = + (hot)
Ring =
– (cold)
Sleeve = GND
The servo balanced input and output circuitry allows to use monaural TS jacks (unbalanced)
with no loss in level. This is the same as when using a TRS-jack with ring connected to ground.
XLR jacks of analog inputs
The XLR jacks are wired according to international standards:
1 = GND (shield)
2 = + (hot)
3 = - (cold)
TRS Phones jack
The analog monitor outputs on the
front are accessible through stereo
1/4" TRS jacks. This allows a direct
connection of headphones. In case
the output should operate as Line
output, an adapter TRS plug to RCA
phono plugs, or TRS plug to TS
plugs is required.
The pin assignment follows interna-
tional standards. The left channel is
connected to the tip, the right chan-
nel to the ring of the TRS jack/plug.
