selection. 
In  this  section  you  can  also  allocate  the  of  physical  outputs  -  “GPO´s”  associated  with  “OFF 
AIR” green lights (i.e. no sources especially microphones, are activated in the studio,) and “ON 
AIR”, red light (i.e. no sources, especially microphones are activated in the studio) of the Studio. 
You can choose between the opto-coupled GPO´s (1 to 8) or the contact relay GPO´s (9 to 12). 
See section 2.2.2.1 of this manual 
 4.2.4.2. CONTROL ROOM SECTION 
This section of MONITORING CONFIGURATION sub-menu lets you choose how the  four keys 
under  the  display  of  the  CONTROL  ROOM  SECTION  shall  work  –  either  in  MIXER  or 
EXCLUSIVE mode. If the option MIXER is selected, the physical outputs associated with CRM 
(CONTROL  ROOM  MONITOR)  and  CHP  (CONTROL  HEADPHONES)  will  act  as  summing 
buses and may therefore  have more than one of  the  four  keys simultaneously activated,  thus 
mixing the signals corresponding to each of the four keys on the control monitoring system  or 
the  control  headphones.  Contrary  to  the  configuration  described,  in  the  EXCLUSIVE  mode, 
these  buses  (CRM  and  CHP)  are  not  summing  buses  and  can  therefore  not  have  more  than 
one  key  activated  at  any  given  time.  This  effectively  means  that  by  pressing  any  of  the  four 
keys, the previously activated will be disconnected from the summing bus and replaced by the 
new selection. 
In  this  section  you  can  also  allocate  physical  outputs  -  “GPO´s”  associated  with  “OFF  AIR” 
green lights (i.e. no sources especially microphones, are activated in the control room) and “ON 
AIR”, red light (i.e. sources, especially microphones are activated in the control) of the Studio. 
You can choose between the opto-coupled GPO´s (1 to 8) or the contact relay GPO´s (9 to 12). 
See section 2.2.2.1 of this manual. 
 4.2.5. NTP Client Configuration Sub-menu 
Access  to  the  NTP  CLIENT  CONFIGURATION  sub-menu  from  the  internal  drop-down  menu 
under “Hardware Configuration”, clicking the icon; 
 “NTP CLIENT CONFIGURATION” sub-menu Icon 
From this sub-menu  you can enable synchronization of  the date and time of the system using 
standard  Ethernet  NTP protocol,  with  the  local  AEQ  FORUM clock  slave  to the remote (NTP) 
signal.
