Quattrocanali ampliers support star network topology
via the Ethernet port and Dante networking via the Dante
port only.
The Ethernet port is designed to allow the remote
control of the amplier through Armonía Pro Audio Suite
and third party software. The Dante port is reserved to
Dante networking.
7 : 1.IP addressing
Factory default network settings are DHCP/AutoIP,
inorder for the amplier to self-congure when connected to
an existing LAN or PC. Fixed IP policy can also be adopted
and congured through Armonía Pro Audio Suite.
If a DHCP server is not active within the network,
the amplier platform initiates a stateless address
auto-conguration (i.e. Zero-conguration networking
methodology – Zeroconf): it self assigns a local numeric
network address (of the type 169.254.x.y – 172.31.*.* for
the secondary network if present – with a subnet mask
255.255.0.0) and automatically distributes and resolves the
host names of the networking devices. For setting a static
IP address please refer to the Armonía Pro Audio Suite user
guide.
7 : 1.1. IP Addressing troubleshooting
When connecting the Quattrocanali to a network
environment it may happen that Armonía Pro Audio Suite
does not discover or import the amplier.
Usually this is a problem of IP addressing: both Armonia
and the Quattrocanali must belong to the same subnet. If a
DHCP server is present on the network and a Quattrocanali
amplier is in AUTO IP, networking may become unstable.
As a rule of thumb, turn the DHCP server
on before connecting the amplifiers.
IP addressing of a Quattrocanali amplier is established
during the bootstrap: when the amplier discovers a DHCP
server on the network during the startup, it negotiates the
networking parameters. If the Quattrocanali does not reveal
a DHCP server on the network during the startup, it set itself
in AUTO IP mode.

If self check cannot be started because of a fault, the
check LED will blink fast, whilst a reassuring slow blink is an
indication of a completed self check procedure.
