Section 2 — Installation
Levels Controlled, Level Tallied (10BPS and MCBP
panels)
The panel may be set to control levels from 1 through 4 or any
combination of these levels. If you are controlling a single
Performer and have not ganged its levels, you will need to
control only levels 1 through 3 corresponding to V, A1, and
A2. If you are controlling multiple Performers and have
ganged their levels so that they switch simultaneously, your
specific application will govern your levels of control choice.
The level of tally is typically the video level (1), but may be
any level from 1 to 4.
The panel silkscreen (illustrated below) clearly indicates
switch segment positions corresponding to levels of control
and level of tally.
In this example,
levels 1, 2, and 3 are
enabled; level 1 is
being tallied.
