THE CHASSIS SYSTEM
INTRODUCTION
The Vision is available in three frame sizes; 19" (14 module positions), 38, and 46 module positions.
The basic frame has two blank modules, both located on the extreme left and right of the frame.
An exception is the 19" rack frame, which does not have blanks on either side.
The extreme left and right blanks on the larger frames cannot be used for input modules as they conceal mechanical
constructions.
The frame 38 will fit 40 input modules ( mono, stereo, group, matrix or master modules).
The frame 46 frame will fit 48 in/output modules.
The master section in the 19" rack version needs to be installed on the far right side of the console.
In other frames the master section and all other modules can be installed wherever most suitable, but the request
must be made at the time of ordering.
