Product Overview
The Shure PGA58-QTR cardioid dynamic vocal microphone is built for lead and backup vocals, presentation, and paging in live sound and commercial AV settings. Its cardioid pattern captures the vocalist or presenter while rejecting room noise and helping control feedback. This configuration includes an XLR-to-1/4-inch (QTR) cable for direct connection to mixers and powered speakers with quarter-inch inputs.
Product Description
The PGA58 delivers clear reproduction across the vocal range, with a tailored cartridge optimized for natural speech and vocal performance. The cardioid polar pattern rejects off-axis sound for cleaner isolation in reinforced rooms, making the microphone a practical choice for all-hands rooms, houses of worship, training rooms, and multi-purpose spaces. A discrete on/off switch lets presenters mute locally without console access. The included XLR-to-1/4-inch cable connects directly to portable PA systems, powered loudspeakers, and mixers that use quarter-inch microphone inputs.
