108 APEX — Installation and Service Manual
Section 3 — Installation
As described on S34-1/2 – Stereo/Mono Mode Selection on page 94 , Apex is
normally set for two-level stereo operation; this allows for stereo mode
switching such as mix, reverse, etc. In this mode the Apex boards are
programmed so that the right channel is always 4 physical level
numbers higher than the left channel. In the case of Jupiter control, the
router would have a two-row entry in the Switcher Description table,
e.g., one for a 256 x 256 Left level (typically Level 32 as described above)
and one for a 256 x 256 Right level (typically Level 36).
Switcher protocol (driver) type is binary .
Note Apex connector numbering is 1 based whereas Jupiter physical input/output
tables are 0 based. This means, for example, that physical input number 0 on
the Jupiter Switcher Input table represents input connector number 1 on the
rear of the Apex chassis.
