Step 7. Using the laptop as your portable studio
The differences between being in the studio and doing an OB
are very few. Once you have set everything up & established
a connection with the Studio you just run your radio program
as normal.
Things to remember are; if your mic line is illuminated 1, 2 or
3 you are live on air! So once you finish talking just turn the
button off.
You need to enable the mic ON approx. 4 seconds before you
start to talk in order to have a constant mic volume level going
to air.
Instead of playing Sponsors, Weather, Assoc. Members and
Promo announcements from the console in the studio, you
will need to insert the messages listed on your run sheet into
the playlist from one of the folders on the desktop. It's quite
easy and you will get it quickly.
You are required, as in the studio, to follow the run sheet for
the OB including News, Sport & Weather announcements.
The folder for these are on the desktop of the Laptop as is
normal in the studio.
