Balanced Cables
Using balanced cables helps eliminate what?
noise/hum/hiss
The most common instrument/guitar cable.
TS
hum/buzz caused by multiple ground paths is called what
Ground Loop
Your standard signal level
Line Level
Cable that is used for microphones, preamps/interfaces, monitor connections, patching balanced gear.
XLR
A balanced cable better known as your "standard mic cable"
XLR
Carries mono signals, so stereo requires two of these ends. Used in mostly consumer gear but some pro audio gear.
RCA
A woven mesh of copper strands around the conductors is what type of cable shielding?
Braided Shield
Line level reference point for 0dBu is equal to how many volts
.775V
Cable that is used for DJ gear (turntables, mixers), older consumer-level audio interfaces, some CD players.
RCA
A balanced cable used in line-level connections
TRS
Looks the same as our common guitar cable, but thicker, and has two equally sized insulated conductors
Speaker Cable TS
A type of shielding that is fragile and breaks easily if flexed a lot.
Foil Shielding
Signal level produced by electric guitars, basses, keyboards, and synths
Instrument Level
Cable that is used for Keyboards, synths, drum machines, DAW controllers, automation data.
MIDI (5-pin/USB)
Can carry 8 balanced audio signals
DB25
Sends performance data, not audio
MIDI
What button on a D.I. box helps with ground loops?
Pin-1 ground LIFT
The absolute weakest signal level
Phono Level
Cable that is used for Digital stage snakes, FOH-to-stage communication, routers, control of powered speakers.
Cat6
Uses what so any interference picked up is canceled out when the two signal wires are recombined
Common Mode Rejection
Sends digital audio via light.
Optical
Why do we want to separate power cables from audio cables in runs (if we are able to)?
Because of the EMI (Electromagnetic Interference)
What frequency range is usually cut when connecting a HI-Z device to a regular line level input?
High Frequency Range
Cable that is used for Power amps, passive PA speakers, subwoofers, stage monitors (safe for high wattage).
