ASERV 1 Routing
Note that there are two routes for each output (source) channel of ASERV1. One goes to the
corresponding digital output of the ASERV 1 IP blade (T-AS1, T-AS2 and T-AS3). The red line shows that
the connection is LOCKED. You definitely want to lock these so that the crosspoints are not accidentally
undone. This mapping will make channel 1 of ASERV1 available at digital output 1 (output 5) of the
ASERV 1 IP blade, channel 2 available at digital output 2 (output 6) of the blade, etc. These will be
connected into your bridge router system where the ASERV sound card outputs used to connect.
The outer route for each ASERV output goes to a UMX (utility mixer) input. The default nomenclature is
BL##UMX1, BL##UMX2, etc. where ## is the blade number. So here we’re feeding ASERV1-1 to blade 17
utility mixer input 1, ASERV1-2 to utility mixer input 2, etc. Note that KLTT G6 is fed to utility mixer input
5. The source BL17UMXA is routed to T-Bus. This connects the A output of the utility mixer in the ASERV
1 IP blade to digital output 4 (output 8). Again, this feeds the station’s audio chain (STL bus). The reasons
for the utility mixer routing will be explained below.
Each IP blade contains a utility mixer which can be used for just about any purpose that requires mixing
or switching sources. The utility mixer has eight mappable inputs and two outputs. In ASERV applications
we map ASERV outputs and the control room program bus to utility mixer inputs. We then use Nexgen
Source On/Source Off commands to turn channels on and off. By doing this we can put the control room
in bypass (ASERV direct to air) or put the control room program bus to air.
