Grand Master Module
Grand Master Module RS5449
The Grand Master, fitted only to VCA consoles, enhances the VCA grouping
system. The Grand Master System provides:
•
two Grand Master faders with cut switches assignable to the eight VCA groups
•
optional external master fader with enable switch allowing remote control of
Grand Master A level.
The system is hierarchical - channels are assigned to the VCA Groups, and VCA
Groups are assigned to the Grand Master. The Grand Master only affects the
channels via the VCA Groups, and not directly.

The Lamp socket allows connection of a goost:neck lamp ("Littlite" or similar)
via a BNC-type connector. Additional lamp sockets are fitted at the left and right
hand ends of the console. The voltage to the lamp connectors is variable from I .SY
to 12V by the Dimmer Control.

A Grand Master is assigned to a VCA group by the Group Assign Switches ;
all channels assigned to that VCA group are then controlled by the Grand Master
as well as the VCA Group. A Grand Master may be routed to any number of groups,
and both Grand Masters may be routed to the same group.
3
The Gr.md Master Faders , together with the VCA Group fader, control the
gain of any channels assigned to the VCA group. The channel VCA gain will be
the sum of the gains set on the VCA Group and Grand Master faders; however, the
combint:d gain of Group and Grand Master faders is limited to+ lOdB.
4
The Cut button will cut any affected channels, muting tht: post-fade signal, and
pre-fade auxiliary sends (unless the sends are st:t pre-mute.) When muted, the Cut
switches on the channels will flash; however, the VCA Group will not light. The
VCA Group Cut switch will also cut the channels.
5
The Remote Enable switch activates an external master fader; this shares the
Grand Master A routing to the VCA groups, and may be used to remotely control
the level of the VCA groups. The remote fader connections are made via a 0.1"
connector on the Grand Master module.
Note: The Grand Master controls are fitted only to YCA consoles. On non-YCA
consoles, the lamp socket and dimmt:r control only are present.
