Introduction to the Shure SM87A Supercardioid Condenser Microphone

The Shure SM87A Supercardioid Condenser Microphone stands out as a premium handheld vocal microphone, delivering warm, accurate lead vocals with exceptional clarity in challenging environments. This rugged, lightweight condenser mic features a highly directional supercardioid pickup pattern, ensuring superior rejection of off-axis noise for high gain-before-feedback during live performances.[1][2][4] Its controlled low-frequency roll-off prevents bass overload, while a three-stage shock mount minimizes handling noise and self-noise remains low at 24 dB A-weighted, making it ideal for professional sound reinforcement.[1][2]

Key benefits include very low RF and magnetic hum susceptibility, built-in wind and pop filters, and minimal impact from varying load impedances, allowing reliable use across stages, studios, and reverberant venues.[1][2][4] Targeted at professional vocalists, sound engineers, and live performers, the Shure SM87A Supercardioid Condenser Microphone excels in noisy settings like concerts or broadcasts. Unique selling points are its electret bias condenser design—rare for handheld mics—with a 10mm diaphragm for smooth frequency response from 50Hz to 18kHz.[3][5]

Powered by 11-52V phantom power via a three-pin male XLR connector, it handles maximum SPL of 140.5 dB and offers 116.5 dB dynamic range.[1][2] Weighing just 200 grams with aluminum construction and steel grille, it's comfortable for extended use.[1][4] Though discontinued by Shure, the Shure SM87A Supercardioid Condenser Microphone remains available through retailers at an estimated price range of $200-$250, providing enduring value for vocal microphone enthusiasts seeking supercardioid condenser performance.[3][6][7]

Troubleshooting the Shure SM87A Supercardioid Condenser Microphone

Common issues with the Shure SM87A Supercardioid Condenser Microphone often stem from phantom power, cable faults, or environmental factors. If no sound is produced, verify 11-52V DC phantom power is supplied correctly to pins 2 and 3—no error codes apply, as it's analog.[1][2] Check XLR cables for damage and ensure load impedance exceeds 800 ohms minimum.[1]

For low output or distortion, confirm SPL doesn't exceed 140.5 dB; reduce proximity or volume. Handling noise? The three-point shock mount addresses this—gently grip and use the built-in pop filter for plosives.[1][4] Hum or RF interference is rare due to low susceptibility; test away from lights or wireless gear.[2] Low-frequency buildup indicates improper positioning—aim for 15-30cm distance to engage roll-off.[1][3]

Prevent issues by inspecting cables pre-use, avoiding drops (rugged but not indestructible), and storing in a dry case. As a discontinued model, Shure honors legacy warranties via authorized dealers; contact Shure support at www.shure.com or local distributors for repairs.
