3.3.4 Zoned Audio
The ADPRO FastTx has one audio input and output. If zoned audio is required, that is the ability
to talk out of individual speakers rather than making a global announcement, or if it is required to
listen to multiple microphones, a VM22A can be used. This also means a mixture of intercoms
and loud speakers can be used.
The VM22A audio switcher has ten audio inputs and outputs (one for each video input) and will
route the appropriate audio input and output to the ADPRO FastTx, depending upon which
camera the monitoring station is currently viewing.
Additional VM22As can be connected to the first VM22A to expand the audio channels to 20 (the
same number as number of cameras on a ADPRO FastTx AFTX-20).
