Vortex Media VTX 1000 - Manual (Page 48)

The VTX Mode Option for Input B needs to be selected so that the SoundStation VTX 1000 can make
wideband audio calls.
Automixer
One of our design requirements was to make each Vortex device operate as one 12-channel automixer in
order to limit the maximum number of open microphones to 4 across both units. In order to achieve that,
we need to set the G
LOBAL M AX NOM to 4 on both linked units. By default, the L OCAL M AX NOM is set to 4
and the Bus Mixer is set to 1 (The Bus Mixer refers to the ability of each unit to send and receive the
Automixing information from each unit over the EFBus. In order for both units to function as one automixer,
the Bus Mixer ID needs to be set to the same value. In this case, the default is 1. A Bus Mixer ID of 0
means that each unit will function as a separate Automixer and that unit will not send its automixer
information to any other linked unit(s)).
