Cards in this set: Term What are the 5 components of a microphone preamp? Definition Gain/Trim, Pad, Phase/Polarity, Phantom Power, Mic/Line Switch Term What is the formula for power? Definition P=I*V P=Power (watts) I=Current (amps) V=Voltage (volts) Term What is the formula for voltage? Definition V=I*R V=Voltage (volts) I=Current (amps) R=Resistance (ohms) Term Where are EQ knobs on a console? In software? Definition On a console, they are within channel strips. In software, they are the "inserts" or "sends". Term In Binary, what do "0's" and "1's" represent? Definition 0's represent off and 1's represent on. Term What does EQ stand for? Definition Equalization Term What are four types of Dynamic Processors? Definition Compressor, Limiter, Upward Expansion, Downward Expansion Term EQ is typically post-tape and pre-fader. True or False? Definition True Term What is an ADC? Definition Analog to digital converter Term What is DAC? Definition Digital to analog converter Term You must have these two types of converters in your signal flow. Definition ADC and DAC Term What is sample rate? Definition The number of times per second a picture is taken of your sound (a snapshot of voltage) (width of stairs) Term What is bit-depth? Definition Binary word length (number of stairs) Term What are common sample rates? Definition 44.1k, 48k, 88.2k, 96k, 176.4k, 192k Term 2 to the 16th power is how many bits? How many voltages can be recognized with this bit-depth? Definition 16-bit, 65,536 different voltages can be recognized Term What is a byte? Definition A digital word Term What are header and footer bits? Definition 8 bits added to either the front, back or both (4 and 4) or a binary word. They tell a computer which signal format you will be working with. Term What is dither? Definition Dither smooths out the stairsteps of digital to analog conversion of the signal. Term 1-bit is how much dynamic range? Definition 6dB Term What is another name for Peak-Notch EQ? Definition Parametric EQ Term What is another name for an equalizer? Definition Filter Term What are the three controls of Peak-Notch (Parametric) EQ? Definition Gain, Frequency, Q Term What is the Q? Definition Quality Effect (shape of bell at -3dB points on either side of peak) Term Does Low-Q have a wide or narrow bell curve? Definition Wide Term Does high-Q have a wide or narrow bell curve? Definition Narrow Term What are three types of EQ? Definition Parametric/Peak-Notch, Shelving, High-Pass/Low-Pass Term On a Peak-Notch (Parametric) EQ, what controls the boost or cut in dB level? Definition Gain knob Term What is a 1-Band Parametric EQ? Definition Only 1 band of frequencies are controlled (Highs, Mids, Lows) with a set of knobs. Term What frequencies are controllable in a 2-Band Parametric EQ? Definition Highs and Lows Term What frequencies are controllable in a 3-Band Parametric EQ? Definition Highs, Mids, Lows Term What frequencies are controllable in a 4-Band Parametric EQ? Definition Highs, High Mids, Low Mids, Lows Term What frequencies are controllable in a 5-Band Parametric EQ? Definition Highs, High Mids, Mids, Low Mids, Lows Term What are two other names for a Semi-Parametric EQ? Definition Quasiparametric, Sweepable Term What is a Semi-Parametric EQ? Definition EQ that has anything less than fully controllable frequency, gain and Q knobs. This includes switchable controls. Term What is shelving EQ? Definition It works on either the low end or high end and is determined by + or - 3dB Term What is the purpose of switching the "EQ ON" function to off? Definition Reduce noise, Avoid extra circuits Term What is another name for a Shelving EQ that only cuts high or low frequencies? Definition High-Pass Filter or Low-Pass Filter Term What is a High-Pass Filter? Definition Low-Cut Filter-Allows frequencies only higher than it's cut off frequency to pass (at -3dB). Term What is a Low-Pass Filter? Definition High-Cut Filter-Allows frequencies only lower than it's cut off frequency to pass (at -3dB). Term How are High-Pass and Low-Pass Filters measured? Definition dB/Octave Rolloff Term Which rolloff is more steep?: 6dB/Octave or 12dB/Octave Definition 12dB/Octave Rolloff Term Is a capacitor hardware or software? Definition Hardware Term What does a capacitor create? Definition Filters and Rolloffs Term In a capacitor, each order gets a deciBel increase of how much? Definition 6dB Term Why do capacitors need to be an odd numbered order? Definition Because a capacitor creates a 180 degree phase shift so an even number of capacitor orders would cancel out all sound. Term What is a 1/3 Graphic EQ? Definition Hardware version of EQ where each 1/3rd octave has a designated slider (3 sliders per octave). Term Is a Graphic EQ artistic or correctional? Definition Correctional Term Where, in signal flow, does a processor fit? Definition Between EQ and Channel Fader Term Processors are also known as inserts. True or False? Definition True Term What type of connector is on each end of an insert cable? Definition TRS connector on one side, 2 TS's on the other. Term Describe the TS connectors on an insert cable. Definition There are two TS connectors on one end of an insert cable. One is labled tip, send or left and the other is labled ring, return or right. Term 0 Vu is how many dBm? Definition +4 dBm Term What are the parameters of compression? Definition Threshold, Makeup Gain, Ratio Term What do the numbers in a compression ratio represent? Definition dB input:dB output Term What is the difference between compression and limiting? Definition Ratio (Limiting ratio is generally about 20:1) Term With compression, what does the red meter represent? Definition Gain Reduction Term What is gain reduction? Definition How much signal is being compressed Term What units are attack and release measured in? Definition Milliseconds Term What is a sudden bend in the dB cut/boost called? Definition Knee Term What is another name for a downward expander? Definition Noise Gate Term A downward expander/noise gate has 3 main controls. What are they? Definition Attack Time, Hold/Decay, Release
