31.2 Connector Pinouts

TRS jacks of analog input / output

The stereo 1/4" TRS jacks of the analog inputs and outputs are wired according to international

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 output on the

front is accessible through a

stereo ¼" TRS jack. 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

international standards. The left

channel is connected to the tip,

the right channel to the ring of the

TRS jack/plug.
