    "best_for": "Studios needing a black-finish U 87 Ai for vocals, voice-over, acoustic instruments or multi-pattern general studio capture.",

    "fit_notes": "The mt designation is the black finish; core published audio specifications match the U 87 Ai family.",

    "verification_questions": ["Is this the black U 87 Ai mt base package, manufacturer catalog number 007023, rather than a Studio Set?","Are the microphone and wooden box included, and is a shock mount included only if the retailer explicitly adds one?","Can the seller substantiate authenticity, serial provenance, and current condition?","Can the intended preamp supply 48 V phantom power, and are the room and mount appropriate for the source?"]

    "summary": "Neumann U 87 Ai mt is the black U 87 Ai large-diaphragm pressure-gradient studio microphone. Neumann specifies omnidirectional, cardioid, and figure-8 patterns, a 20 Hz–20 kHz range, switchable low cut and 10 dB preattenuation, transformer-balanced output, 200-ohm rated impedance, 117 dB maximum SPL in cardioid or 127 dB with preattenuation, 48 V phantom power at 0.8 mA, 500 g weight, 56 mm diameter, and 200 mm length. It is a versatile choice for vocals, speech, voice-over, acoustic instruments, cabinets, drum overheads, classical spot recording, and piano when its room pickup and price are justified. The base U 87 Ai mt order entry is catalog number 007023 and lists the microphone plus wooden box; the EA 87 mt shock mount belongs to the separate Studio Set. Confirm the exact variant and package before purchase. This is an external verified retail listing reference, not Envoy Music inventory or fulfillment.",
