D-Sub Analog Inputs / Outputs

The 25 pin D-sub connectors of analog input and output are wired according to the Tascam

scheme, as shown in this table:

Channel 1+ 1- 2+ 2- 3+ 3- 4+ 4- 5+ 5- 6+ 6- 7+ 7- 8+ 8-

D-sub 24 12 10 23 21 9 7 20 18 6 4 17 15 3 1 14

GND is connected to pins 2, 5, 8, 11, 16, 19, 22, 25. Pin 13 is unconnected.

The servo balanced input circuitry allows to use unbalanced connections with no loss in level.

For this to work, pins 3 (-) and 1 (GND) have to be connected.

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 inputs / outputs

The stereo ¼" TRS jacks of the analog inputs are wired according to international standards:

Tip = + (hot)

Ring = – (cold)

Sleeve = GND

The servo-balanced 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.
