33.7 Connector Pinouts

Pin assignment of the 9-pin D-sub connector, breakout cable SPDIF / AES
Note: The digital breakout cable is identical to the one used in HDSPe series cards.
Pin Name
1 GND
2 SPDIF Out +
3 SPDIF In +
TS jack analog output
The 1/4" TS jacks on the rear are wired according to international standards:
Tip = + (hot), Ring = GND, Sleeve = GND.
XLR Connectors
The XLR sockets of the analog I/Os are wired according to international standards:
1 = GND (Shield), 2 = + (hot), 3 = - (cold).
The servo-balanced input 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.
!
The XLR outputs do not operate servo-balanced! When connecting unbalanced
equipment, make sure pin 3 of the XLR output is not connected. A connection to ground
might cause higher THD (distortion) and power consumption!
TRS Phones jack
The analog output channels feed
two Phones outputs
independent driver circuits.
In case these outputs should oper-
ate as Line outputs, 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.
In Balanced Mode operation the TRS
outputs change
stereo to balanced mono operation. An
adapter cable as shown to the right
gives balanced phones with 4-pin XLR
connector access to the ADI-2 Pro
outputs.
Using mini XLRs the pinout (signal to
pin number) is identical.
