88192 A/D D/A Converter
Basic Setup
8. Rotate the encoder to adjust the input gain for the selected input (1).
The gain is adjusted in real time.
9. Push the encoder when finished to deselect the input.
10. Repeat steps 7-9 for any additional inputs needing adjustment.
11. Press the exit button three times to return to the main status screen.
C. Verify routing: By default, the 88192’s analog inputs are routed
to the ADAT outputs and the ADAT inputs are routed to the analog
outputs. To verify this, visit the routing menu using the following steps.
1. Ensure that you are starting at the main status screen, menu level.
Press the exit button until you get to the main status screen. Refer to
Appendix A for illustrations.
2. Push the exit button once to go to the menu level 2, Setup - Main.
3. Rotate the encoder to highlight “Route”.
4. Push the encoder to enter the routing menu.
5. Verify that “Analog INs ’ ADAT OUTs” and “ADAT INs ’ Analog
OUTs” are both shown.
6. Press the exit button twice to return to the main status screen.
D. Adjust analog output levels: By default, the 88192 is configured
to output +4 dBu nominal balanced line level outputs. However, if your
destination device(s) expect something closer to a consumer -10 dBV
nominal unbalanced line level, the 88192’s analog outputs can be
adjusted to match.
1. Ensure that you are starting at the main status screen, menu level.
Press the exit button until you get to the main status screen. Refer to
Appendix A for illustrations.
2. Push the exit button once to go to the menu level 2, Setup - Main.
3. Rotate the encoder to highlight “Analog”.
4. Push the encoder to enter the analog menu.
5. Rotate the encoder to highlight “Analog OUTs: Level”.
6. Push the encoder to enter the Analog OUTs: Level menu.
7. Push the encoder to toggle analog output 1 between +4 and -10
output levels.
8. Rotate the encoder to select additional outputs for adjustment and
push the encoder to toggle as necessary.
9. Press the exit button three times to return to the main status screen.
E. Adjust sample rate: By default, the 88192 is configured for a 44.1
kHz sample rate. For this basic setup, we want to use 48 kHz. The
following steps detail changing the sample rate.
1. Ensure that you are starting at the main status screen, menu level.
Press the exit button until you get to the main status screen. Refer to
Appendix A for illustrations.
2. Push the exit button once to go to the menu level 2, Setup - Main.
3. Rotate the encoder to highlight “Sync”.
4. Push the encoder to enter the sync menu.
5. Push the encoder to select “Internal: 44.1 kHz”. Notice that
“44.1 kHz” begins to flash indicating that it is selected for adjustment.
6. Rotate the encoder until “48 kHz” is displayed.
7. Push the encoder to confirm “48 kHz” as your choice. Notice that
“48 kHz” is no longer flashing indicating that it is no longer selected
for adjustment.
8. Press the exit button twice to return to the main status screen.
Basic Setup - Conclusion
This concludes the basic setup. If you have followed the previous Basic
Setup sections completely, you should have the correct hardware
connections and the 88192 should be set up correctly. Now, provided
that you have your record sources, mixing console, recording device
and monitor system set up correctly, you should be able to get signal
flowing through the 88192 and get some recording done! Please
consult the user’s manuals for your other devices to ensure they are
set up correctly to work with the 88192. Do not forget to set your
recording device to accept ADAT format digital inputs at 48 kHz
and for the recording device to receive its digital sync from its ADAT
inputs. Anytime there is a digital connection between devices, there
can only be one “master” and all others must be “slaves” to it directly
or indirectly. A master is the device to which all other devices sync. In
short, your recording device should not be set to any type of “internal”
sync unless you like listening to clicks and pops!
When all else fails...
When you’re miserably lost, settings are completely out of whack
or when you just want to make a fresh start, there is a factory reset
function which will restore the 88192 to factory defaults.
WARNING! This process will completely erase all
current settings contained in the 88192. Be sure that you
have documented any necessary settings
(routing configurations, etc.) first!
Factory Initializing the 88192:
1. From the home screen, navigate to menu level 9.1: Setup -
Miscellany (refer to Appendix A).
2. Rotate the encoder until “Defaults: RESET” is highlighted and push
the encoder.
3. Press the exit button twice to return to the main status screen.
