The Level Meters
The 764 level meters are vertical bar graphs in which the height of
each bar indicates the amplitude of the audio program contained on
the corresponding input channel. The levels of all four input channels
are shown in the default meter configuration, illustrated in Figure 15.
You can also select — through on-screen menus — “two channel plus
sum and difference” mode, shown in Figure 16.
Indeed, almost every feature of the 764 level meters may be
customized to suite your particular needs. The features and your
options are explained briefly in the following numbered paragraphs.
Choose the options that are appropriate to your particular application
through the on-screen menus; refer to Configuring the Level Meters
beginning on page 22 for more information.
