  1. to switch from ipod to cd
    hold down left button and hit source select
  2. industry standard audio
  3. audio console/mixing board
    accepts output signals from sound sources, feeds intro separate input channels on the board, operator can then amplify, mix and route them to air, recording device, studio or talent
  4. input
    channels that get signals from various sources and sends them to output. mics have one channel. stereo line sources has two channels.
  5. peak light
    red, when illuminated, a signal is too loud in the channel and needs to be lowered using gain/trim pot
  6. +48V
    phantom power switch to activate external power supply for phantom power capable condenser microphones
  7. phase
    reverses phase of input signal by 180°
  8. gain/trim potentiometer
    controls input level with a pre-amplifier before it goes through the rest of the board. allows for a balance in the slide faders
  9. EQualiser section (red)
    alter the channel's frequency response by boosting or cutting the volume of specific signal frequencies. Treble/high frequencies, high middle, low middle, and bass/low frequencies. left pots adjust the volume of the frequencies in the range, middle pots select specific frequencies, right pots allow Q (width) adjustment of specific frequencies.
  10. humans hear
    frequencies from 20-16,000 Hz
  11. high pass filter
    bass roll-off filter, cuts off the volume of frequencies below a certain frequency. we use 63 Hz for surface noise and appliance hum. 120 V is electrical system.
  12. output assignment switchers
    routes input signals to specific output sections. LR for master L and R fader and MONO
  13. mix minus
    when you send everything out to studio except miss
  14. panoramic potentiometer
    shifts balance of sound between two master output channels (L and R), center for mics.
  15. slide fader
    should always be set at the reference line -10 for 100% modulation when used with the gain/trim pot
  16. solo (orange)
    cue, prefader line, allows speaker in audio to monitor individual channels without affecting the program output.
  17. L&R fader
    collects the LR output signals sent from all the input channels in one place before moving from the board to air and/or a recording device
  18. mono/sel
    collects the MONO output signals sent from all the input channels in one place, before moving from the board to the studio
  19. monitor
    meters and speakers. samples various signals in the other sections, visually watch meters, neither metering nor monitoring will affect the signal being broadcast or recorded
  20. meters
    visually measure signal flow thru a console or audio device. 1. soundcraft board peak program meters: LR and MONO. 2. Dorrough loudness meter (VU Meter), combo unit
  21. speakers
    mon level pot to adjust speaker volume in the audio control room only
  22. Volume Unit meters
    measure signal flow thru a console or audio device, average sound intensity (amplitude) in dBs (-20 to 3) and percentage of modulation (0-100%). reference point is 0dB=100%
  23. slate/talkback
    mic mounted on or inside board. slate verbally identifying takes on a recorded tape, talkback allows for communication with performers
  24. oscillator
    pure tone at specific frequency (1kHz), calibrates recording or playback levels on tape machines using VU meters, slating takes or for engineering alignment. channels 29 and 30
  25. patch bays
    access to audio source outputs and audio board inputs. top row are outputs, bottom row are inputs. jacks without a line between them indicate the normal connection, the # of ins and outs determines flexibility.
  26. hit
    faders at proper full level
  27. fade up
    keep fade up time to a minimum (2 seconds or less)
  28. cross-fade
    fade one source out as another is faded in for 2 seconds
  29. modern surround sound
    5.1 channels
  30. matrices
    group of buses and faders
  31. numbers in digicart
    first is hard drive, next is directory , next is cut within directory
  32. digicart audio resolution
    48,000 samples per second
  33. normalize the board
    load the cue list "rtvf normal"
  34. play digicart file continuously
  35. mic access panels
    two in each studio, one has 12 inputs, the other has 1-9. never plug 2 mics into the same channel at different access panels.
