Functional Diagram
As can be seen, the VNET control data from the IN connector is fed to both the LINK and OUT
connectors so from a data point of view the unit can be considered as a “Y” splitter, something
that is useful in its own right.
The unit sends any AES3 present on the IN connector only to the LINK connector. AES3 for the
OUT connector can only come from the AES3 IN XLR.
Connections
VNET IN - The VNET2 network input “daisy chained” from the previous device. It carries
network control data, and may also contain AES3 digital audio from upstream devices.
Net LINK - Essentially the same signal as the Net IN connector. This is used to pass exactly the
same data on to the next device in the chain, including the AES3 audio channels from upstream
(NOT the audio channels inserted by this break-in interface). This is useful when you have a
main backbone’ network which is passed from device-to-device, but you also wish to “tap-o”
one or more branches carrying dierent audio channels.
Introduction
This Quick Start Guide presents only the essential information required to properly unpack,
connect and congure an AES3 Break-in Interface for VNET2 systems. Please consult the full
AES3 Break-in Interface for VNET2 Operation Manual for additional detailed information.
Overview
Feed AES3 digital audio to many VNET2 devices
• • Use several in a network to create zones
• • Rugged steel enclosure
• • Free-standing or rack-mount options
• • Standard or Neutrik® etherCON® RJ45 connectors
• • VNET Network cable powered
• • No special cables
What is VNET2?
VNET2 is next generation VNET with the capability of transporting 2 channels (one AES3 stream)
of high-quality uncompressed digital audio on the same cable as the control network. The AES3
break-in interface for VNET2 is used to connect the AES3 source to the VNET2 network with the
minimum of complication.
Like VNET and other similar networks, VNET2 uses Cat-5 cabling to attach up to 119 devices
using a simple cabling scheme without requiring any other network equipment such as hubs.
The total span of the network is at least 1000 m (3,281') without repeaters and without digital
audio. This reduces to a maximum of 600 m (1,969') when transporting 48 kHz AES3 and 400 m
(1,312') for 96 kHz AES3 (VNET2 products automatically adjust themselves to any incoming
sample rate between 32 kHz and 96 kHz). There is no maximum length for a single span within
these limits and individual products will safely bypass themselves from the network if they are
unpowered, allowing the other devices to work normally.
Note that if VNET2 is conveying AES3, products must only be wired in “daisy chain” fashion
using their IN and LINK connectors. Star congurations should not be used.
