Cards Term Define soldering. Definition The fusing of metal objects Term What does AWG stand for? Definition American Wire Guage Term What is the relationship between wire guage and the thickness of the wire? Definition Inversely proportional. The higher the guage the thinner the wire Term Name the three types of shielding. Definition Braided Shield, Foil Sheild, Wrapped Sheild Term What type of sheilding is best for moving cables? Definition Braided Term What type of sheilding is best for permanant installation? Definition Foil Sheild Term What are the three types of noise? Definition RFI (Radio Frequency Interference), ESI (Electro Static Interference), and EMF, (Electro Magnetic Frequency) Term In cables without sheilding such as Ethernet or phone cables, how is interference reduced? Definition Twisted Pairs Term What happens when the cable capacitance is increased? Definition It acts as a Low Pass Filter Term What happens when the cable resistance is increased? Definition Loss of Dynamic Range Term What is circuit ground? Definition Your 0v Reference Point Term What is Rosin? Definition A type of flux that enhances the fusing of two conductors Term What is tinning? Definition Pre-coating an iron or conductor with solder Term Why do we pre-heat conductors? Definition To prevent Cold Solder joints Term What is the difference between an open and a short? Definition An open has an infinite number of Ohms of resistance, and a short has 0 ohms of resistance Term What are the common balanced connectors? Definition TT (patch cables), 1/4" TRS, and XLR Term What are the common unbalanced cables? Definition T/S (Instrument cables) and RCA Term When wiring a balanced cable to an unbalanced cable what gets wired where? Definition HI goes to HOT and LO and SLEEVE go to GND Term Define Fully Normalled Connections. Definition All 4 normalling connections are hooked up so patching into the send or the return will break the original connection Term Define Half Normalled Connections. Definition 2 of the Normalling connections are hooked up, so only patching into the returns will break the connections Term How do you wire a TRS cable to be an insert? Definition Wire the tip to send, the ring to the return, and the sleeve to the ground Term What does an oscillator do? Definition Generates Waveforms Term What does an Oscillascope do? Definition Measures the current running through it Term Define Voltage. Definition The difference in electrical potential between two points Term What are the three types of voltage? Definition AC, DC, and AC with a DC offset Term What is Pro Line Level? Definition 1.23 V Term What is Consumer Line Level? Definition .775 V Term What is Mic Level? Definition 40-80 mV Term What is speaker level? Definition 6-8 V Term What type of AC current doeas a DMM measure? Definition Vrms (Volts Root Meanh Squared) Term What type of AC Voltage does an Oscilloscope measure? Definition Vpp (Volts Peak to Peak) Term What are the two types of Tape Calibration? Definition Mechanical Cal and Electrical Cal Term What happens to a tape machine if demagnitization is not performed regularly? Definition Loss of High Frequencies Term What do we use for play cal? Definition MRL (Magnetic Reference Laboratory) Term What is Reference Fluxivity? Definition The term for the volume level on tape Term What is an operating level? Definition Amplification level for record and playback Term How do we store analog tape? Definition With the tails out in a cool, dry environment Term What are the types of audio inputs and outputs? Definition Active, Passive, Balanced, and Unbalanced Term What type of component requres power? Definition Active Term Which pin on a component typically has a visual reference? Definition Pin 1 Term What is an IC socket used for? Definition Easy chip replacement, and heat dissapation Term What is the PCB letter and units for a resistor? Definition R, Ohms Term What is the PCB letter and units for a Variable Resistor? Definition VR, Ohms Term What is the PCB letter and units for a Capacitor?
