Aux Sends & Mix-Minus Assignments
Press the Set button to activate the Input view on the monitor. Across
the middle are four sets of controls to set how that channel feeds the four
Aux Send busses.
At the bottom left are four Mix-Minus bus assign buttons. Tap/click to
light a button solid to assign that channel to that mix-minus bus.

The controls on these two views were covered on pages 60 - 63.
GSX APPLICATIONS
The GSX console is most often used in an air studio to control the audio
going to a transmitter and/or streaming to the Internet. In almost all
cases, the PGM bus is used to feed the air chain and hence has the air
signal. The AUX and/or AUD bus can be setup to simultaneously create a
different console mix for an internet or a syndicated program feed, to feed
a recorder or a mic skimmer, or to feed a line output to send audio to a
video camera or personal recorder.
When the console is used in an air studio, and there is no talk studio
associated with the console, the Studio monitor controls can be
"repurposed" for other uses.
One typical use is to control the monitor source feeding the guest
headphones in the control room to allow the board operator to change
their own monitoring source without affecting the guests' headphone feed.
The studio monitor source is then cross-connected to the guest headphone
amp destination that goes to a Talent Station's headphone amp (a couple
examples are shown in Figure 4-17).
The studio monitor output would be set to a fixed level, rendering the
Studio Monitor level control inactive. The studio monitor controls would
still be used to select the monitor source for the guest headphones. This
allows the board operator to freely switch between control room monitor
sources without affecting the audio going to the guest headphones. It also
gives the board operator the ability to talk into the guest headphones
using the TB (studio talkback) button.
The Studio monitor output could, alternately, connect to a newsroom or
to a sports bullpen which doesn't have a networked console, but which
goes live to air. The mics in that room would be set as "studio mics" which
mute the studio monitor output while on. Their monitor source would
typically be a "Pre-Delay" feed. The board operator can then talk to the
talent in the newsroom or sports studio using the TB button. If studio
monitor speakers are not required, then the studio output could be used to
feed a headphone amp. In this case the mics would not be set to mute the
studio monitor output but would be set to trigger the studio hot mic
warning tally.

Network Origination
Flagship stations for sports teams often need to have a second output
from their main air signal to function as a regional sports network feed.
This output is typically identical to their local broadcast signal except it
doesn't have the local commercial spots and liners. It may also require
adding special signal tones or other logic commands.
Creating a secondary network is easily done by using PGM as your main
broadcast output and using AUD or AUX as your network feed. If the
media server channels are setup to consolidate local spots and station
liners on certain channels, then those channels can be unassigned from
AUD or AUX, whereas the national spots playback channel(s), and the
game liners and the play-by-play remote inputs, would be assigned to
both the PGM bus and the AUD or AUX bus.
Production Usage
In a production studio, PGM is typically the main record signal for an in-
room PC running Pro Tools
system.
If the Wheatstone WNIP audio driver is installed on the PC, and that PC
is networked with your WNIP system, no analog, digital, or external logic
connections are required since the audio will be streamed over Ethernet
for both recording and playback while the logic will use TCP commands to
send logic requests back and forth between the PC and the GSX.
WNIP audio drivers are available to support one stereo channel up to
twenty-four stereo channels for playback and recording. Soft logic
commands (SLIO) are then available to control channel functions like
