rtvf final audio board

hold down left button and hit source select

wheatstone

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

channels that get signals from various sources and sends them to output. mics have one channel. stereo line sources has two channels.

red, when illuminated, a signal is too loud in the channel and needs to be lowered using gain/trim pot

phantom power switch to activate external power supply for phantom power capable condenser microphones

reverses phase of input signal by 180°

controls input level with a pre-amplifier before it goes through the rest of the board. allows for a balance in the slide faders

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.

frequencies from 20-16,000 Hz

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.

routes input signals to specific output sections. LR for master L and R fader and MONO

when you send everything out to studio except miss

shifts balance of sound between two master output channels (L and R), center for mics.

should always be set at the reference line -10 for 100% modulation when used with the gain/trim pot

cue, prefader line, allows speaker in audio to monitor individual channels without affecting the program output.

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

collects the MONO output signals sent from all the input channels in one place, before moving from the board to the studio

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

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

mon level pot to adjust speaker volume in the audio control room only

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%

mic mounted on or inside board. slate verbally identifying takes on a recorded tape, talkback allows for communication with performers

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

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.

faders at proper full level

keep fade up time to a minimum (2 seconds or less)

fade one source out as another is faded in for 2 seconds

5.1 channels

group of buses and faders

first is hard drive, next is directory , next is cut within directory

48,000 samples per second

LOOP

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.
