NETBOX 32 AD / NETBOX 8 AD / NETBOX DSP
Audio over IP multichannel interfaces

If the boards are wired to a dedicated audio network using a switch, only LAN 1 should
be blinking. If the wiring is connected in "Daisy Chain" mode, without switches, or there
is a redundant network, both LEDs should be blinking. IMPORTANT NOTE: When there
is a redundant network, primary and secondary interfaces must be connected to
separated networks.
AUDIO LEVEL LEDs: Each LED indicates the level of the corresponding device audio
input / output:
•
LED off: the channel is muted, or transmits or receives (depending on whether
it is an output or an input) at a level below -60dBFS.
•
Green LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -60dBFS and -20dBFS.
•
Amber LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -20dBFS and -6dBFS.
•
Red LED: the channel is saturated or "clipping" (above -6dBFS).
2.2.2. Description of the back panel and connections.
2.2.2.1. Ethernet Ports (LAN 1 and LAN 2).
NETBOX 8 includes two Ethernet ports: LAN 1 must always be wired, while LAN 2 is only used
when the system is wired in "Daisy Chain" mode or a redundant system is set up. IMPORTANT
NOTE: When there is a redundant network, primary and secondary interfaces must be
connected to separated networks.
Physically, both are RJ45 10/100/1000, connectors, with the pinout described below:
