CX-34000 Control Crosspoint Board Configuration
Please refer to the CX-34000 assembly drawing in Figure 41 on page 98 for
the following configuration switch instructions.
S34-1/2 – Stereo/Mono Mode Selection
The Apex is normally operated in two-level stereo mode (both switches
OFF ). This mode, which is also referred to as split stereo, 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.
With S34-1 ON and S34-2 OFF , the switcher will operate as one physical level,
which is considered standard AES mode. This mode is also referred to as
Locked Stereo .
With S34-2 ON , the switcher will operate in Mono mode. In this case a
256 x 256 router is configured as a 512 x 512 mono router.
