Input sockets – Balanced XLR mic/line inputs with +48V Phantom Power
indicator. The preamps are built into the GX4816 and their Gain, Pad and +48V are
controlled from the mixer via the Cat5 link.
The +48V indicator detects voltage at the socket whether supplied by the GX4816 or
received from an external source.
Output sockets – Balanced XLR outputs operating at nominal +4dBu level.
Mains power – IEC connector and power switch for the built-in universal
voltage PSU. This accepts voltages from 100 to 240V AC. Secure the cable to the
plastic P-clip using a T20 screwdriver.
 Heed the safety warnings printed on the panel.
Status indicators – The Ready indicator lights up when the output sockets
are ready to pass audio after power up. Power indicates the correct functioning of the
PSU.
GX port – EtherCon port for connection to the mixing system over Gigabit
Ethernet. A single Cat5e (or higher) cable carries multichannel audio at 96kHz and
control.
DX ports – EtherCon ports for connection of DX Expanders over Fast
Ethernet. Each cable carries 32x32 channels of 96kHz audio and control. Connect a
single DX32, or up to 2x DX168 / DX164-W per port.
 DX1 and DX2 on this device cannot be used for redundancy
purposes.
 When connected to a ME-U, ME-1 or ME-500, the DX2 port is
self-configured as a 40ch, 48kHz output only port for the ME
personal mixing system. Channel names and stereo links are
communicated to connected ME systems, and the ME output
patch temporarily replaces the output patch to the DX2 port.
