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 Pin Name Pin Name
1 GND 4 AES Out + 7 SPDIF In -
2 SPDIF Out + 5 AES In + 8 AES Out -
3 SPDIF In + 6 SPDIF Out - 9 AES In -
TRS jack analog output
The 1/4" TRS jacks on the rear are wired according to international standards:
Tip = + (hot), Ring = - (cold), Sleeve = GND.
Pentaconn
Standard wiring: Tip +L, R1
–L, R2 +R, R3 –R, Sleeve connected to 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 via two independent driver circuits.
In case these outputs should operate as Line
outputs, an adapter TRS plug to RCA phono
plugs, or TRS plug to TS plugs is required.
The pin assignment follows international stand-
ards. The left channel is connected to the tip,
the right channel to the ring of the TRS
jack/plug.
In Balanced Mode operation the TRS outputs
change from unbalanced 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-2/4 Pro SE outputs.
Using mini XLRs the pinout (signal to pin number)
is identical.
