Music & Audio Advice Microphone Placement Techniques 2 — Questions and Answers
Question 1: When close-miking an acoustic guitar, where does aiming the mic at the 12th fret instead of the sound hole typically help?
- It reduces boomy low-end buildup (Correct answer)
- It increases bass response
- It eliminates string noise entirely
- It captures only the pick attack
Correct answer: It reduces boomy low-end buildup
The sound hole emits a strong bass resonance, so aiming at the 12th fret yields a more balanced, less boomy tone.
Question 2: What is the main reason for using the 3:1 rule when placing multiple microphones?
- To minimize comb-filtering from phase interference (Correct answer)
- To boost overall gain
- To widen the stereo image
- To reduce background hiss
Correct answer: To minimize comb-filtering from phase interference
Keeping the distance between mics at least three times the source-to-mic distance lowers bleed and phase cancellation.
Question 3: For a kick drum, placing the mic inside the shell close to the beater head tends to emphasize what?
- The click and attack of the beater (Correct answer)
- The room ambience
- The low sub rumble only
- The snare bleed
Correct answer: The click and attack of the beater
Positioning near the beater captures the transient click that helps the kick cut through a mix.
Question 4: When recording a grand piano for a pop track, placing mics over the hammers rather than far back produces what?
- A brighter, more articulate attack (Correct answer)
- A darker, distant tone
- More pedal noise only
- Reduced note definition
Correct answer: A brighter, more articulate attack
Close placement over the hammers emphasizes attack and clarity suited to dense pop mixes.
Question 5: Why might an engineer place a microphone off-axis to a guitar amp speaker cone?
- To roll off harsh high frequencies (Correct answer)
- To increase treble harshness
- To eliminate all midrange
- To capture more room reverb
Correct answer: To roll off harsh high frequencies
Moving toward the edge of the cone naturally reduces brightness for a warmer tone.
Question 6: What does the proximity effect cause when a directional mic is placed very close to a vocalist?
- A boost in low frequencies (Correct answer)
- A cut in low frequencies
- Increased high-frequency hiss
- A loss of all bass
Correct answer: A boost in low frequencies
Cardioid and other directional mics exhibit increased bass response as the source gets closer.
Question 7: For overhead drum mics in a spaced-pair configuration, what is the primary goal of careful equal-distance measurement?
- Keeping the snare centered and in phase (Correct answer)
- Maximizing cymbal volume
- Removing the kick entirely
- Adding artificial delay
Correct answer: Keeping the snare centered and in phase
Equal distances from each overhead to the snare keep it phase-coherent and centered in the stereo field.
