APPENDIX 3. SIGNALING AND CUT FUNCTIONS INSTALLATION WITH FORUM AND
CAPITOL CONSOLES.
A3.1. Example: STUDIOBOX (or SCR-03) control box - NETBOX 4 MH
- CAPITOL IP.
In this example, a typical scenario in radio studios will be explained, where the several
participants in a program have microphones and headphones located in a booth, connected via
a Dante network to the mixing console (CAPITOL or FORUM IP) in the annexed control room.
By means of a NETBOX 4 MH in the booth, those audio signals are sent and received to / from
the studio mixing console (CAPITOL or FORUM IP) through a Dante network. Additionally, the
commentators have a STUDIOBOX (or SCR-03) control box in front of them, which is
connected to the NETBOX 4 MH itself, allowing it to send commands and control its signaling
lights using the mentioned mixing console.
In this example, these will be the actions to perform in the mixing console:
-
The control box signaling lights will be used as follows: RED light will be ON when any
of the booth’s microphone inputs is ON. The GREEN light will turn ON in the opposite
case (both lights are mutually excluding).
-
MUTE (or CUT) key will cut the first input sent to the console (“MIC1”), and TECH T.
BACK (or CUE) key will activate its PFL (prefader listening).
-
The 4 first user keys (USER1-USER4) will activate / deactivate each of the 4
microphone lines (“MIC1” to “MIC4”) sent by NETBOX 4 MH.
-
Fifth key (USER5) will control a light in the console that will blink indicating the studio
technician that the commentators need some help.
Device data:
-
NETBOX 4 MH IP address: 172.31.39.4
-
CAPITOL IP IP address: 172.31.34.11
Physical connection of the STUDIOBOX (or SCR-03) to NETBOX 4 MH, that will be located in
the booth, is direct as, besides generic GPI/O interfaces, the later features two I/O interfaces
that are completely compatible with this booth control box: one is for signaling outputs for 2
lights, and another carries 2 dedicated key (MUTE + TECH T. BACK; or CUE + CUT) inputs
plus 5 more general-purpose keys. Two RJ-45 connectors are used, and their pinout is detailed
in section 2.3 of this manual.
In order to obtain more details about the physical connection, please check section 2.2.3.
Once the box is connected, NETBOX 4 MH device must be configured by means of its
configuration application, "NetBox 4 MH Tool", in order to define the virtual GPOs to be sent in
response to each box’s key, the Virtual GPIs that will activate its RED and GREEN lights, as
well as the remote device IP address (a mixing console, in this case), plus a unique identifier for
each one.
NOTE: In order to manage the control box by means of virtual GPIOs, it's necessary that the
"GPIOs Transport" option is NOT activated (see section 3.2.2.1 of this manual).
