On this page you will find a description on how to add digital output hardware to your dBox / Mediamaster. This article is based on the page of Manfred Boehmel (the original page went offline).

1. What you need...
2. Build the Circuit board...
3. Connect your board to the Box
Be careful not to damage the smd capacitor or the audio decoder due extreme heat or static electricity. Ensure that you did not short multiple pins of the crystal chip.
If everything is ok, you can reconnect your cables and power on the box. You should see a red light inside the TOTX now.
4. Reconfigure the Software
Upload the latest DVB2000 firmware into your Box. In Menu-8-9 you have to Enable AC3. Then you have to set all your channels to AutoPid:ON.
go to Menu-9-4 and enter:
For a CS4922 and a Harman Kardon AVR35RDS these settings work fine. For other receivers you might need other XMTCS values.
Sometimes you have to reboot the Box or reset the DSP (Menu-9-0) to produce a correct audio signal.
On of the most frequent problems is the message "CL sucks". This Message appears if you produced a short-circuit on the I2C bus of the box. In this case, please check the soldering points on the crystal chip. If you dont see a red light inside the TOTX, you either already burned the TOTX or the power supply cables are not connected correctly.
