| Question | Answer |
| What is a powered mixer | -are all in one devices that have an amplifier built into one of the mixer outputs |
| What is a auto mixer | -has a gate on each input that opens when a speaker is present but keeps other channels muted -used when there will be no operator present |
| What does DANTE stand for and what does it do | -digital audio network through ethernet -connects all aspects of your audio signal to be routed through ethernet -no need for lots of different types of cables to your computer |
| How many channels in and out does DANTE allow | -16 in -16 out |
| What does DANTE require | -one of their devices to act as the word clock master |
| What does the DANTE virtual sound card do | -acts as the i/o between a computer and DANTE devices |
| What does the DANTE system controller do | -used to configure a DANTE network |
| What is a matrix output | -an additional output of a console -matrix outputs are fed by another consoles outputs |
| What are the three weightings used in SPL meters and some info about each | -a weighting = designed to reflect hearing of human ear, has greater sensitivity from 500Hz to 6000kHz -c weighting = designed to measure all frequencies audible to the human ear 20Hz to 20kHz -z weighting = flat frequency response from 10Hz to 20kHz |
| Why use mute groups | -so you could mute vocals, drums, guitar, etc. when one of them are not needed |
| What is a common way to jump from mix to mix | Put aux sends on your faders |
| Why should side fills only be used when necessary | -because they cause a large amount of stage noise |
| What can you do if your performer feels disconnected from the crowd | -add audience mics |
| What should you insert across each aux send | -a 31 band eq to ring out the wedges |
| What does it mean to "split the channels" | -when you separate the front of house mix from the monitor mix with a y cable, split snake or digital console |
| What is the use of a stage rack | -it converts analogue signals to whatever digital protocol the console would like to see |
| What do stage plots show | -the preferred set up of the stage and should hopefully have great detail |
| What is the smallest unit of a picture that can be controlled | -a pixel |
| What does the resolution tell you | -the # of pixels used in an image |
| What does the aspect ratio tell you | -the dimension of a picture based on width to height |
| What is an interlaced video | -a video that produces half of the image with every frame |
| What is a progressive video | -a video that contains all of the information with every frame |
| What are the two most common composite cables | -RCA and BNC |
| How many signals are component cables broken into | -3 red, green and blue |
| What cable is most common for professional video production | -DVI |
| What is keystoning | -when a projector image is not projected properly because the projector may be sitting at an angle to the screen |
| If a projector has a throw ratio of 2:1 and your screen is 10' wide how far away does it need to sit | -20' away |
| What is the light output of projectors measured in | -lumens |
| What is double convergence | -when two projectors are double up to double the lumen output |
| What is an IRE and what does 100 IRE mean, how about 7.5 IRE | -institute of radio engineers units -100 IRE is white -7.5 IRE is black |
| What is the native resolution | -the actual # of pixels wishing a monitor or projector |
| What is the EDID | -Extended Display Identification Data -a signal from a projector telling the computer what resolution it would like to see |
| What is video scaling | -the process of changing the resolution of a video signal |
| What is a tally light | -found on professional monitors and tells the operator when their camera is live |
| What is high bandwidth digital content protection | -a form of digital copy prevention to prevent piracy of digital audio and video content |
| What is mixing and compositing | -mixing is the process of switching between multiple sources -compositing is the process of having two screens in one |
| What is the downstream key | -allows the introduction of graphic or green screen effects |
| What is the LUMA key | -setting the brightness level so that all of the brighter or darker pixels disappear |
| What is the Chroma key | -removing one colour (usually green or blue) from the top (downstream) layer |
| What is extended display | -creating a secondary video output from the computer that is separate from the display screen |
