Proper Microphone Technique

Once you have a great-sounding source, the next job is the right mic in the right place. Both matter, and both get sorted before you reach for EQ.

A/B test to find the right mic

Every voice and every source has a unique profile, so the best mic is the one that sounds best on it. If you have the luxury, do a shootout: set up two mics at a time and sing (or play) back and forth, “championship bracket” style, letting the engineer listen at the board. In this course’s vocal shootout the DPA 2028 won, with the SE V7 MC1 runner-up and the Shure KSM9 third — but the loser still wins on someone else’s voice. That’s the whole point: different mics suit different sources.

Dynamic vs. condenser

The two workhorses of live sound:

• Condenser — more sensitive, picks up high-frequency detail and nuance more easily, smoother overall. Great for distant miking: choirs, drum overheads, audience mics, and vocals on a quiet stage. The downside of that sensitivity: on a loud stage a condenser grabs everything around it (lots of drum bleed).
• Dynamic — rugged and great at rejecting bleed, so it shines on loud stages and floor monitors. Perfect for close, loud sources: guitar cabs, snare, toms. It handles high sound-pressure levels without flinching. (The Shure SM58/SM57 is the famous example — nearly indestructible.)

This course uses condenser vocal mics because the stage is quiet (drum cage, low stage volume). On a loud stage, dynamics would be the call.

Placement

Where you put the mic shapes the sound as much as which mic you choose.

• Vocals — don’t eat the mic. Getting too close builds up low end (the proximity effect) and turns the voice muddy, forcing the engineer to cut it. Leave about two fingers between mouth and mic for a natural sound.
• Proximity effect is a tool. Closer = more low end; that can work for or against you. Use it intentionally.
• Snare: a couple of fingers up, aimed at the center. Before EQ-ing a weird snare, check the mic — did it get bumped or drop so it’s no longer pointing at the drum?
• Electric guitar cab: small moves = big tonal changes. Toward the center of the cone is brighter; off to the side is darker. Move the mic before you grab EQ.

A real-world example

Brian couldn’t get enough low end out of the toms, and the team kept boosting EQ to compensate. The real fix wasn’t EQ — it was the mic: swapping to Sennheiser e421 / MD 421 Compact mics immediately brought the low end out.

Find the right mic, try the right placement, get a good source — all of that happens before you ever touch your EQ.

Application

• A/B test mics on your lead vocalist (and your snare) and pick the winner by ear.
• Coach your vocalists on the two-finger rule this week.
• Next time a source sounds wrong, check the mic and its placement first before reaching for EQ.
