Shure KSM44A/SL Multi-Pattern, Large Diagphragm, Side-Address Conde...
Product Overview
The Shure KSM44A/SL is a multi-pattern, large-diaphragm, side-address condenser studio microphone for engineers who need flexible pickup and exceptionally quiet operation. Selectable cardioid, omnidirectional, and bidirectional patterns plus Prethos Advanced Preamplifier Technology make it a versatile studio condenser microphone for vocals, acoustic instruments, and ensemble capture. As a large-diaphragm condenser for commercial recording, it delivers a wide dynamic range with industry-leading low self-noise.
Product Description
The KSM44A/SL is built around externally biased dual 1-inch diaphragms that enable three selectable polar patterns: cardioid for focused single-source capture, omnidirectional for natural room pickup, and bidirectional figure-8 for stereo and dual-source techniques. Prethos Advanced Preamplifier Technology achieves a groundbreaking 4 dB of self-noise and a 127 dB dynamic range, so the microphone captures quiet detail and loud transients cleanly up to a 131 dB maximum SPL. Extensive internal pop filtering reduces breath and plosive noise without an external screen. The microphone requires phantom power and performs best on a 48V DC supply per IEC-61938, while still operating with reduced headroom on supplies as low as 11V. It integrates into any commercial-grade preamp or interface through a standard XLR, suiting broadcast studio, house of worship, and auditorium recording. 
Key Features
- Three Selectable Polar Patterns — Cardioid, omnidirectional, and bidirectional patterns adapt the microphone to single sources, room capture, and stereo techniques.
- Dual 1-Inch Externally Biased Diaphragms — The large dual-diaphragm capsule delivers detailed, full-bodied reproduction across sources.
- 4 dB Self-Noise — Prethos Advanced Preamplifier Technology reaches a groundbreaking 4 dB self-noise for clean capture of quiet passages.
- 127 dB Dynamic Range — A wide dynamic range with a 131 dB maximum SPL handles both subtle detail and loud transients.
- Extensive Internal Pop Filtering — Built-in pop filtering reduces plosives and breath noise without an external screen.
- Flexible Phantom Power — Optimized for 48V DC (IEC-61938), it still operates with reduced headroom on supplies as low as 11V.
Typical Applications
- Broadcast studio
- House of worship
- Auditorium
