(All Unity AM menu choices with range adjustments use percentages, except in the Crossover Sub-
menu where frequency values are used )
The Left Input should be highlighted. If it is not, press one of the Select buttons until it is highlighted.
This indicates that the left channel input level can now be adjusted. By rotating the jog wheel under
the LCD screen, the input level can be adjusted. To adjust the Right Input press one of the Select
buttons to highlight the Right Input Adjustment of the right channel audio level can now be
accomplished. After adjusting, the input levels, press the Enter button to store the adjustments within
the system.
If you do not press the Enter button, the settings will default back to the previous
settings. Please make note of this requirement, as it affects any menu choice that requires
setting an operating range.
To set your input levels correctly, we will use the Input Level located on the far left of the Processing
Display.
Run a typical audio source into your Unity AM. As you adjust the input levels up and down using the
jog wheel, you will observe the Input Level Meters are multicolored. At higher inputs, the level
meters will show red at the top of the scale. Proper input levels for the Unity AM should have the first
and second red meter indicators light on peaks approximately 50% of the time. With a +4dBm input,
this should occur when the input ranges on the Menu and Parameter Section of the LCD screen are at
50%. (If you have the Unity AM set for -10dB operation, the 50% settings apply when a –10dB input
is provided.)
Remember that the Wide Band AGC will accommodate input levels that may be a little too high or a
little too low. For best Unity AM performance, with lowest noise and processing artifacts, you will
want to set the input levels properly. When you are finished adjusting the input levels, press the
Escape button twice to return the LCD display to the Home Screen.
Setting the Unity AM output levels
If the indicators on your transmitter or other device indicate that the output levels are too high or too
low, use the following procedure to adjust the output level. Be certain of which output(s) you have
connected to which device(s) before you begin. Individual controls are provided for the two outputs.
This will allow equipment requiring different output levels to be adjusted appropriately.
Starting from the Home Screen, press the Clipping button to access the menu. Use the jog wheel to
select the Discrete Output Sub-menu and press the Enter button. Use the Select buttons to highlight
the Output Level you wish to modify. Use the jog wheel to adjust the bar graph to the desired level. If
you wish, again use the Select buttons to highlight other Output Level you wish to modify. When
done, press the Enter button to store your new settings and you will be returned to the Clipper Menu.
Note:
For stereo operation the two outputs can be used for the left and right channels. When setup in
the Matrix Processing Option, output #1 is for the L+R signal, and output #2 is for the L-R signal.
