an "up" or "down" arrow key and, for every
push, the level will change .1 dB. Clicking
on the button labeled "Flat" will restore all
slider settings to the mid point and will warn
you (if you accidentally hit it) before acting
on the command.
Note: If a channel should appear high-
lighted in red, it indicates that the
channel has been muted on the Outputs
Screen (see Section 7.7).

7.7 Outputs Screen.

This is where, during the alignment process,
the output levels are set for the various
channels. A signal generator is available
which can be set to four different modes.
To select the particular generator function,
choose the function with the radio buttons
on the bottom of the screen. To assign a
particular channel to receive generator
output, a box is available below the slider.
These boxes may also be utilized to Mute
or Invert the channel. The faders change in
0.5 dB increments.
Note: When using the generator, the de-
fault mode allows one active channel at
a time. Holding down the <control> key
allows selection of multiple channels for
the generator (e.g., center and subwoofer
channels).

7.8 Slit EQ Analyzer Screen
To the right of the Preamp Level Faders is a
screen with annotations on the bottom and
left side and buttons at the top. This is the
Real Time Analyzer built into the JSD-80.
You must be connected to the JSD-80 and
it must have a signal source before it can
become functionally effective. Move the
mouse arrow over one of the buttons and
a pointer appears. Click the "Power" button
and a line appears across the screen. You
can utilize the Real Time Analyzer in the fol-
lowing ways: utilizing the third button from
the top left, you can select either Normal or
Sum & Diff. In the "Normal" mode, you have
the option of selecting (with the second top
button), either Left, Right, or Left + Right. In
the Sum & Diff mode, you can select (with
the second top button), either Sum, Diff or
Sum + Diff. You can view the performance of
the left channel and right channel, Sum or
Diff as either bars or lines. On the left hand
side of the screen are gradations measured
in decibels. As you can see, they often ex-
tend below the level of the screen. Moving
the mouse pointer over these gradations
and holding down button one, a pointer
appears once again, with an accompany-
ing arrow. You can move the numbers and
the screen up to view the signal, down to a
level of -50 dB and up to +20 dB if so desired.
Double click on the screen and it expands to
a larger representation that can be seen at a
greater distance. The larger screen can then
be maneuvered on the computer's screen to
access controls.
