Behringer DCX2496
For the transceiver boardthe jumpers are:
1= OFF
4,5,6 = ON
7 = OFF
8 = ON
First thing to do is to drill and mount the RCA jacks for the S/PDIF outputs. The Behringer rear panel does not have much free room so adding these to the left side of the Behringer when viewed from the front is one option.
The S/PDIF board fits well to the left of the main processing board in the Behringer. Use several layers of 3m double sided extra strength foam tape to mount the board. 3 or 4 layers of tape should be plenty to make sure there are no shorts between the board and the chassis.
DACs used AKM AK4393
The relevant pins on the AK4393
Pin 3 = Master Clock
Pin 5 = BitClock
Pin 6 = Serial Data
Pin 7 = L/R Clock
For those three connections above you only need to make the connection from any one of the three DACs to the 3x S/PDIF output board. Any location on the board that has continuity to those pins on the DACs is fine to tap into.
Pin 6 on each DAC is the serial data pin. Take pin 6 of one dac and connect it to INSD1 on the output board. Pin 6 of the second dac goes to INSD2 on the output board. Pin 6 of the third DAC goes to INSD3 on the output board. There are three surface mount resistors near the DACs (R3, R4, R5) which are good tie in points for the serial data for each DAC as shown in the picture below.
Lastly ground and power need to be connected to the transceiver board.
Then the 3x S/PDIF outputs need to be wired into the board.

Installation information for 3x SPDIF Digital Output in Behringer DCX2496 digital crossover
The above picture shows possible tap in points for the clocks and serial data.
From Left to Right above
1 (white wire) goes to serial data 1
2 (white wire) goes to serial data 2
3 (blue wire) goes to Master Clock
4 (blue wire) goes to Bit Clock
5 (blue wire) goes to L/R Clock
6 (white wire) goes to serial data 3
This shows one of many possible tap in points for the connections. Any point that has continuity with the appropriate DAC pin is suitable to use.
In the picture at the top of the page the black wire is ground and the white wire all the way to the left is +5v DC.
NOTE: The Behringer runs all processing at 96/24 so the S/PDIF outputs will likewise always output 96/24.
