Front Panel 

 

 

 

 

  

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 n4dBu 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.
