Chapter One:

Introducing the 8x8 Analog

and 8x8 AES Nodes

This section will allow you to get to know the 8x8

Node and describes the unit’s features, display, and con-

nectors.

Description

The Axia Livewire 8x8 Audio Node has eight stereo

inputs, and eight stereo outputs. 8x8 Analog nodes have

balanced analog inputs and outputs whereas the 8x8

AES nodes have AES3 inputs and outputs. Therefore,

each 8x8 Node can create 8 stereo Livewire streams,

each of which becomes available to other devices on the

Livewire network.

Each stereo output can be assigned to output a stereo

Livewire stream acquired from the network.

Basic point-to-point (e.g. “Livewire Snake”) appli

cations require only two Livewire nodes and a category

6 “Crossover Ethernet cable”. More sophisticated mul

tipoint networks can be used by connecting multiple

Livewire nodes to an appropriate Ethernet Switch.

NOTE: Only an approved, and properly programmed

Ethernet switch, incorporating the proper Multicast and

QoS standards may be used.

Front Panel Controls and Indicators

The Livewire 8x8 Audio Node incorporates a number

of front panel indicators to allow the operator to verify

proper operation quickly and conﬁdently.

Status LED indicators

Four LEDs indicate the status of the Livewire and

Ethernet connections, as well as system synchronisation

as follows:

LINK

When illuminated continuously, this LED represents

the presence of a live Ethernet link to another Ethernet

100 Base-T device. This LED indicates that a connec-

tion is present and some device is connected. It does not

indicate the quality of the connection however. If no Eth

ernet link is present, this will ﬂash slowly.

LIVEWIRE

This LED indicates that the connected Ethernet seg-

ment has Livewire trafﬁc present. If the link LED is il-

luminated, and the LIVEWIRE LED fails to illuminate,

there are either no other Livewire devices connected, or

the Ethernet switch has not been programmed to pass

such trafﬁc to the port to which this node is connected.

SYNC & MASTER

Only one of these two LEDs should be illuminated,

with the one exception noted below. If neither LED il

luminates, something is not correct. The SYNC LED

indicates the receipt of clock information from another

(Master) Livewire Node. The MASTER LED indicates

that this node is acting as the master clock source for the

Livewire network. More speciﬁcally:

SYNC – If Sync packets are being received by the

Livewire node, this LED will begin to ﬂash. The LED

will continue to ﬂash until the Livewire node has locked
