Livewire TM
If you are already familiar with Axia's audio nodes, you might think of this new version of the
Zephyr Xstream as an "original" Xstream codec with a 2x2 node on the front of it. The LAN port
will be used for all Livewire audio connections in and out of the codec. As with all Livewire
devices, the Livewire streams being delivered to the network require unique ID numbers.
The two most important concepts to understand are:
TM
1. The Livewire destinations deliver audio to the inputs to the Xstream codec.
2. The outputs of the Xstream codec (Hybrid Channels) will become the codec's Livewire
sources to your Axia Livewire network.
The virtual 2x2 node, in combination with the codec, has some unique mono/stereo features:
•
If the stream being received by the codec is stereo ‐ both codec outputs (Livewire
sources) will be stereo with both delivering identical stereo streams.
•
If the stream being received by the codec is dual mono (such as G.722), the decoded
audio is split between the two Livewire
replicated on both left and right channels. The second source has the B mono feed on
both channels. Thus ‐ when you are using dual mono, you will use both codec outputs
as independent Livewire sources.
•
Remember, Livewire
described above, the mono data is simply replicated on both left and right channels.

Dual/Mono TRANSMIT works only in Layer 3 Dual/Mono mode. In Layer 3 Dual/Mono
transmit; the left channel of the first destination is used to create the "Channel A" mono
feed to be sent over ISDN. The second destination is used for the "Channel B" mono
transmit feed. The right channel of each of those streams is ignored.
A Word about Livewire Codec Backfeeds
Backfeeds to a codec in the Livewire
the backfeed is a L/R mono sum of the configured program source (usually PGM1). The left
channel is the same PLUS talkback. The left channel program can be dimmed or muted when
talkback is present.
