Connector Definitions
This section defines the pin outs of the different connector types on the Alero rear panel.
VC - Video Conferencing
The 5-pin 3.5mm Phoenix VC connection is used to connect video conferencing systems to Alero. The line level audio stream may
be fed into the VC input to be broadcast over room speakers amplified by another piece of equipment, like AMX’s DVX, that is
connected to the Alero PA line level output. Alero’s VC output connector provides a clean audio signal to the conferencing unit from
the local meeting room to be broadcast to the remote meeting space.
Line In/Line Out
The 3.5 mm 3-pin captive-wire Phoenix connectors (FIG. 8) marked Line In and Line Out provide left and right channel analog line
levels for inputs and outputs. This interface can be used for a separate audio conference device with POTS dialing capabilities or
used as a record and playback interface.
PA Speaker Output
The 5-pin 3.5mm Phoenix speaker connection (PA) provides a room line level left and right channel outputs to connect to an
amplifier or amplified device. This could go to an Enova DVX All-In-One Presentation Switcher which would then control the volume
to conference room speakers.
