15.9 Connector Pinouts

D-Sub Analog Outputs
The 25 pin D-sub connectors of the analog outputs are wired according to the Tascam scheme,
as shown in this table:
Chan. 1+ 1- 2+
D-sub 24 12 10
GND is connected to pins 2, 5, 8, 11, 16, 19, 22, 25. Pin 13 is unconnected.
The output circuitry does not operate in a servo-balanced way. When connecting unbalanced
devices make sure that pin 3 (-) stays unconnected.
TRS jacks analog outputs
The stereo ¼" TRS jacks of the analog outputs are wired according to international standards:
Tip = + (hot)
Ring = – (cold)
Sleeve = GND
The servo-balanced circuitry allows for the use of monaural TS jacks (unbalanced) with no loss
in level. This is the same as when using a TRS-jack with ring connected to ground.
