Installation manual

Theatre 1
In the preceding diagram of a typical Theatre installation, the Stage Manager operates a two-channel
Main Station, which also powers the system. Several single-channel beltpacks are connected to Chan-
nel A. The beltpacks are used by curtain, spot, patch panel, and light board operators. Communication
between these people and the Stage Manager is on Channel A.
Some Main Stations contain a Tone Alert function. This will audibly signal the Stage Manager if the
stage personnel press the Call buttons on their beltpacks. If needed, the Tone Alert function can be en-
abled using the button on the front panel. The volume of this signal can be set using the Tone Alert
Volume control.
An audio mixing console output from the stage pickup microphones is connected to the Program Input
of the Main Station. If desired, this audio can be placed at a low (or any) level on Channel A. The
level can be adjusted using the Channel A Program Level trimpot. If this audio is to be interrupted by
communication from the Stage Manager, then the Channel A On-Off-Interrupt switch should be set to
the INTERRUPT position. If stage microphone audio should be heard on Channel A at all times, the
On-Off-Interrupt switch should be set to the ON position. If it is not desirable to have audio from the
stage microphones on this intercom channel, the On-Off-Interrupt switch should be set to the OFF
position.
