The 828mkII and 896HD can pass through D/A or A/D audio even in standalone mode. Using the Firewire Cuemix Console, you can set up your 4 stereo busses to accommodate your conversion (the 828mkII can set up using the front panel's knobs as well).

For Digital to Analog, use Firewire Cuemix Console to:

1. Set Bus 1 to output to Analog 1-2
2. Set Bus 2 to output to Analog 3-4
3. Set Bus 3 to output to Analog 5-6
4. Set Bus 4 to output to Analog 7-8
5. On Bus 1, mute all channels except ADAT 1-2 and make sure the faders are up and the channels are hard-panned left and right
6. On Bus 2, mute all channels except ADAT 3-4 and make sure the faders are up and the channels are hard-panned left and right
7. On Bus 3, mute all channels except ADAT 5-6 and make sure the faders are up and the channels are hard-panned left and right
8. On Bus 4, mute all channels except ADAT 7-8 and make sure the faders are up and the channels are hard-panned left and right

This will route every incoming ADAT channel to a discrete analog output.

For Analog to Digital, do the same but switch your outputs to ADAT and activate the analog channels.
