Question | Answer |
Electromagnetic Induction, rugged, higher SPL, cardiod polar pattern | Dynamic Mic Characteristics |
converts Acoustic energy to Electrical energy | Transducer |
Operate on electrostatic principle, Capsule contains two thin plates, sensitive, flat freq response | Condenser Mic (Capacitor) |
electromagnetic induction, Commonly use extremely thin aluminum ribbon, Often a step-up transformer is used, warm sound | Ribbon Mic |
Responds to sounds emanating from all directions | Omnidirectional |
Diaphragm responds to relative differences in pressure b/w front, back and side | Directional |
How a microphone reacts to certain frequencies | Frequency Response |
3Hz-25Hz | Rumble |
Increase in bass response (usually around 200Hz) whenever a directional mic becomes closer (1 foot or so) to the point source | Proximity Effect |
How quickly a ␣␣␣␣␣ diaphragm reacts to the initial attack of a sound wave | Transient Response |
The amount of amplification needed to raise the mic level to line level | Sensitivity Rating |
Microphone output (push) to preamp/device input (pull) | Output Impedance |
Senn 421 | Which is better for miking a cab; Senn 421 or AKG 451? |
directional | Mic type that induces proximity? |
Distance between mic 1 and 2 must be 3 3x that of its source | 3:1 rule |
when is the 3:1 rule applied? | Spaced Pair or A/B |
French Horn Mic? | RCA 77dx |
starting point for miking cab? | 2-6" pointed slightly away from cone |
characteristics that most affects freq. response | Diaphragm size |
best isolation on cymbals? | High pass filter |
Mics used on drums in class | KICK: d6, RE20, D112 SNARE: SM57 HI HAT: SM81 RACK TOMS: Senn 604, senn 421 FLOOR TOM: RE20, 421 OVERHEADS: 414, 451 |
3 best piano mics? | AKG 451, AKG 414, Neumann TLM 103 |
3 word process that describes interference elimination in a balanced system? | Common mode rejection |
mic picks up more ambient noise than source | Critical Distance |
4 stereo miking techniques | a/b, x/y, spaced pair, Decca tree, midside |
Vocal mic placement | 6" away from face, 3" above mouth, 45* back |
