A vocal mic with exceptional clarity
The Shure KSM11 is a premium cardioid condenser vocal microphone built for live performance, event recording, and high-end streaming – a working mic for the channel that always has to be right. Its 3/4" gold diaphragm sits in an advanced suspension that decouples the capsule from handling vibration, while a three-stage plosive filter built into the hardened steel grille keeps breath blasts and consonant artefacts out of the signal. The result is a vocal that lands clean enough to work with as captured – so it can be EQ'd by choice, not by necessity. Standard XLR, 48V phantom power, and no on/off switch to accidentally mute mid-performance – the KSM11 is pared down to what matters most over a touring schedule: clean performance, no surprises.

A heart of gold
The KSM11's 3/4" gold diaphragm covers an 80Hz–20kHz frequency response, with a 149dB max- SPL leaving headroom for the loudest belted vocal at point-blank range and a 130dB dynamic range carrying the same channel from a whispered intro to the climax of a stadium chorus without noise floor or clipping. Its 19dB SPL self-noise sits well below the threshold of any live PA, so the audience only hears the performer; the 75dB signal-to-noise ratio keeps the transmitted signal clean even pushed hard at the desk. At 239g, the KSM11 has the reassuring weight expected from a touring mic: It's heavy enough to settle, light enough to forget.

Crystal clear when it counts
The KSM11 is built for singers and the engineers who mix them – touring vocalists working in front of full PAs, broadcast desks running long live shows, and production crews who need the lead vocal to come up clean and stay clean. It's already on stage with Miley Cyrus, Dua Lipa, and Tyler, the Creator, where the demands on a vocal channel are highest and the margin for fixing it in the mix is lowest. The same capsule is also available as a wireless module (RPW192 and RPW194) for ULX-D and Axient Digital handheld transmitters – so the studio mic, the wired stage mic, and the wireless mic on the same rider are sonically identical.

About Shure
The American company Shure began developing microphones during the early 1930s and is one of the pioneers of the audio engineering sector. Models such as the 55 Unidyne – known to many as the "Elvis microphone" – and the SM57 and SM58 which appeared in the mid-1960s are still ubiquitous in live sound production today. They enjoy cult status among musicians and technicians alike. In the 1990s, Shure introduced the first wireless microphones and in-ear monitoring systems and became a market leader in this field. In addition to microphones, Shure offers a wide range of earphones and headphones for studio and live use, as well as various accessories.
Linear where it's needed
The KSM11's frequency response is flat where it matters – no resonant peaks to dodge with EQ, no honk to subtract from the lead vocal channel. The proximity effect, inherent to any cardioid, is well tuned: Worked close, it adds warm low-end presence without softening intelligibility – the way an experienced vocalist expects a vocal cardioid to behave. Crucially, the response stays linear up to 3kHz even when a singer wraps their hand around the grille, avoiding that cupped-mic tone that turns a clean vocal muddy and pushes a stage rig towards feedback. The KSM11 ships with a mic clamp and a zip-up case – ready for the stand, the rider, or the road.
