When Slit Loss EQ is selected a graph of the slit loss adjustment is shown on the right of the
screen (see Figure 18 below). The goal
is to achieve a flat response. Each frequency level

A projector select button is located below the graph: Projector 1 = Proj1 and projector 2 =
Proj2. Press the button to select.
The Level number above the Proj button is a general indicator of the input signal level that
can be used to confirm there is a valid signal. In Figure 18 the Level is -7dB, which is typical
when playing pink noise.
A button to allow switching between Right and Left channels is located to the right of the
Proj button. Press this button to select the channel.
