FILIBUSTER LIMIT SET OF GATED INPUTS
Filibuster - The Filibuster feature limits the
maximum number of inputs which can gate on
in a given mixer. If the two 4-input mixers in a
4800 or 4800EQ are combined, the total num-
ber of inputs which are gated on in the com-
bined mixer count toward the limit. The limit
can be set at 1, 2, 3, 4, or ALL. The ALL setting
defeats the feature. If mixers are combined
and the limit on a particular mixer is set for 2,
an input on that mixer can gate on only when
the total number of inputs which are on on
both mixers is less than 2. A jumper MUST be
placed in one, but not more than one of the
positions, or erratic performance may re-
sult. The figure below shows the details of
jumper placement. Inputs for which the Digital
Attenuator has been defeated do not contrib-
ute to or affect the Filibuster limit, although
they are still subject to it. As shipped from the
factory, there is a jumper in the ‘All’ position,
defeating the Filibuster feature and allowing
all inputs to be on.
