Dynamic

Moving-coil vocal and instrument microphones, the part of the mic locker that takes the most abuse and asks the least in return. Core lines include the Shure SM58 and BETA 52A, the sE Electronics V7 family in its full run of colours and switched variants, and stage dynamics from Sennheiser and Audio Technica.

Dynamics need no phantom power, tolerate very high sound pressure levels and survive being dropped, which is why they remain the default for live vocals, guitar cabinets and drums. They are also the microphones you hand to someone else without worrying, which matters more in hire stock and schools than any specification does.

The practical choices are pattern and switch. Cardioid models such as the SM58 are forgiving of technique and monitor placement, and a singer who moves off axis loses level gradually. Supercardioid designs trade a tighter front pickup for a rear lobe, so a wedge sitting directly behind the microphone is now in the worst place rather than the best, and the pattern only pays off if the monitors move with it. Switched versions make sense for conference and rental use where the presenter controls the microphone; on music stages most engineers prefer switchless bodies that cannot be muted by accident halfway through a verse.

For kick drums and bass instruments, purpose-voiced large-diaphragm dynamics carry low end that a vocal microphone will not, and they are built to sit inside a drum where the level would overload most condensers. On guitar cabinets, position matters more than model: a few centimetres across the cone changes the sound more than swapping between two respected microphones will.

Wireless users can get the same capsule voicing as a screw-on head for handheld transmitters, listed under wireless capsules, which is the cheapest way to change how a radio system sounds.

The SM58 against Beta 58A against Nexadyne comparison settles the vocal question, choosing live microphones covers pattern and placement, and the drum miking guide covers kick, snare and toms.

Dynamic Microphone FAQs

Why are dynamics the live default? No phantom power needed, very high SPL tolerance, and they survive being dropped, which matters more in hire stock and schools than any spec sheet figure.

SM58, BETA 58 or something else? The eternal question, answered properly in SM58 vs BETA 58 vs Nexadyne, with the sE V7 family the value pick of the range.

What about drums and guitar cabs? Dedicated dynamics like the BETA 52A own kick and cab duty; placement and choices are in how to mic a drum kit.
