SIGNAL FLOW AND THE TECHNICAL RIG

Audio

directional microphones hanging from the studio grid follow an XLR cable into the Stopbox from there they connect to RACK. The RACK then follows in a cable to the sound mixer. the sound mixer has individual faders which control each microphone and other sound sources. You can create a equal mix of the microphones to make sure they are not distorted by moving each fader either up or down on that sound source until its the right level any level from -6 to +9 is good. You can test the sound source via speakers or monitor. The speakers allow you to listen to the quality of the audio.Then it leads out into what we are recording in to.

On the sound mixer their is also a VU meter that is used to see the output sound DB. If the sound output is too quiet you wont be able to hear very clearly on your recording source, however if its too loud you will get distortion. the VU meter has coloured lights They show you the DB range. Green being quiet an red being loud. the perfect DB range is from -12 to +9 with 0 DB being the best.

Video

camera plugs into a adapter box usually underneath the camera which then follows a cable back into the studio terminal outlet box (STOB). this then is also connected a RACK which connects all vision sources into the vision mixing machine. that's four inputs from the four cameras and one input from the DVD player. The vision mixing machine has lots of buttons each representing either a camera or the DVD players input and shows these on a small LED screen with the input channel marked next to the LED screen. it also has another screen at the end of the button which shows black. when ever using the Vision micing maching always start from black and end in black to prevent input showing from other vision source that isn't needed. the Vision mixer operates the vision mixing machine and tests the quality of the vision with their eyes. Once the vision mixer is happy with a vision source they can press the button that represents that vision source which in turn will put that vision source online which then travels out of the vision mixing machine via a output cable into the HDD.
