Basic Setup
Basic Setup - Illustration
The following illustration details the connections (for option 1 digital
connections) in a visual format. In this setup, audio will flow into the
88192’s analog inputs from a multi-channel line level source (in this
case a mixing console’s record path), out the 88192’s ADAT output into
a recording device’s ADAT input, out of the recording device’s ADAT
output back into the 88192’s ADAT input and finally out the 88192’s
analog outputs to a mixing/monitoring device. The 88192 will be the
digital clock master and the entire system will operate at 48 kHz. This
would be a typical setup for multi-track recording.
Basic Setup - Menu Navigation and Software
Setup
The 88192’s user interface consists of a Monochrome VFD display, a
push-button rotary encoder and a single momentary push button.
The encoder’s rotary action is used to both move between menus on a
screen as well as cycle through menu item choices within those menus
which have more than one choice.
The encoder’s push button action is used as a select, toggle or enter
function. For menu items with more than one choice, the push button
action will select the item for editing. You can then use the rotary
action of the encoder to dial through the available item choices. When
finished, push the encoder one more time to deselect and thus confirm
your choice.
On the home screen, the push button action will toggle between the
status screen and the metering screen.
For menu items with only two choices, the push button action will
toggle between the two choices.
For nested menu items, the push button action will navigate down into
the next menu tree.
The single momentary push button primarily acts as an exit button. It
is used to navigate to the next highest menu tree or to exit back to the
main status screen. However, when already viewing the main status
screen, this button is used to go to the initial menu tree (level 2). Refer
to Appendix A for the full menu structure.
Pressing the “exit” button while turning the encoder clockwise will
enable the screen lock function. While in screen lock, no menus may
be navigated and no parameters may be changed. To exit screen lock,
hold the “exit” button while turning the encoder counter-clockwise.
To get familiar with the 88192’s user interface, let’s go through the
menus to verify the necessary settings required to make our basic
setup work and make changes as needed.
A. Reset to defaults: Normally, this step should not be necessary,
especially with a new unit. However, it is included in this basic setup
section to ensure everyone starts from the same state avoiding
potential confusion.
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 “System”.
4. Push the encoder to enter the system menu.
5. Rotate the encoder to highlight “Miscellany” and push the encoder to
enter the Miscellany menu.
6. Rotate the encoder to highlight “Defaults: RESET”.
7. Push the encoder to reset the 88192 to its default settings.
8. Press the exit button twice to return to the main status screen.
B. Adjust analog input levels: By default, the 88192 is configured
to accept +4 dBu nominal balanced line level inputs. However, if your
input source(s) are somewhere off that mark, some adjustment can be
made on the 88192’s analog inputs. Adjusting the levels of the 88192’s
inputs should be considered a last resort, or at least not a substitute for
high quality microphone preamps.
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 INs: Gain”.
6. Push the encoder to enter the Analog INs: Gain menu.
7. Push the encoder to select analog input 1 for adjustment. Notice that
a real-time meter is displayed showing the current input level for the
selected input (1).
