39.2 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 and outputs
The XLR jacks are wired according to international standards:
1 = GND (shield)
2 = + (hot)
3 = - (cold)
The electronic driver circuit of the XLR outputs does not operate servo-balanced! When con-
necting unbalanced equipment, make sure pin 3 of the XLR output is not connected. A con-
nection to ground will cause higher THD (distortion)!
TRS Phones jack
The analog monitor outputs on the front are
accessible through stereo 1/4" TRS jacks.
This allows a direct connection of head-
phones. In case the output should operate
as Line output, an adapter TRS plug to RCA
phono plugs, or TRS plug to TS plugs is re-
quired.
The pin assignment follows international
standards. The left channel is connected to
the tip, the right channel to the ring of the
TRS jack/plug.
