In addition to the 16 channel monitor that is installed in the outside broadcast vehicle, a second 16 channel HD monitor is installed in the central rack room in the Delhi headquarters of Doordarshan Kendra (DDK) which is the arm of DD responsible for the transmission of all broadcast output. Aside from general monitoring applications, this unit is also used in tracking down faults in the broadcast infrastructure. If a fault is detected in the rack room, the signal is routed to the Bel unit via a patch panel and the audio and video signals can be individually auditioned and tested. One of the two Bel BM-AV2-8SHD eight channel audio and video monitors is also installed within this facility.

A further 16 channel BM-AV2-16SHD is installed within the ingest room at DD News and is connected to the output of the main router. Whilst mainly being used for monitoring of VTR signals this unit too doubles as an aid to tracking down issues in the signal path. DD News is also home to the second Bel eight channel HD AV monitor. The BM-AV2-8SHD is installed within the production control room where it is mainly employed de-embedding and monitoring audio signals on the main production desk.
