    "best_for": "Location and classical recording engineers capturing 5.0\/5.1 surround — orchestral, choral, and concert-hall work — who want a complete, manufacturer-matched OCT rig. The OCT geometry (center cardioid plus supercardioid L\/R 8 cm behind and 40-90 cm apart) is specifically designed for strong separation between the front L\/C and C\/R sectors and a clean, discrete center channel, and the compact CCM mics with the included MAB 1000 bars and CB-MAB bracket mount as a single flyable array.",
    "who_should_skip": "Anyone recording only in stereo (the smaller OCT Set, No. 129003, covers L\/C\/R front-only with 3 mics), and anyone targeting immersive 3D\/height formats — SCHOEPS makes the OCT-3D Set (No. 129005) with four additional upward-facing supercardioids for that. Also not for engineers who need standard XLR mics without adapters: these are Lemo-connector CCM compacts, converted to XLR-3M via the included K 5 LU cables.",
    "fit_notes": "The L\/R supercardioid spacing (40-90 cm) sets the recording angle, so the array is tunable to the ensemble width. All five mics run on 12 V or 48 V phantom power (4 mA \/ 3.6 mA per mic) and share identical 46 mm x 20 mm, 45 g bodies. The CCM 41's supercardioid pattern has a null near 125 degrees and directivity SCHOEPS compares to a short shotgun through midrange, which is what keeps front-sector crosstalk low. Set part number 129004 is confirmed on both the manufacturer and retailer pages.",
    "watchouts": "Naming: SCHOEPS itself calls No. 129004 the 'OCT Surround Set'; 'OCT Five Channel Surround Set' is the retailer's name for the same part number. Spec conflicts: Long \u0026 McQuade lists CCM 4 max SPL as 132 dB, while the manufacturer's current CCM 4 page states 136 dB SPL at P48 (128 dB at P12) — prefer the manufacturer figure. Frequency-range and sensitivity figures published by SCHOEPS for the MK 4\/MK 41 capsules (40 Hz-26 kHz) are measured with CMC 6 amplifiers, not the CCM compacts; the 40 Hz-20 kHz \/ 13 mV\/Pa CCM 4 figures here come from a retailer listing. The Economik listing showed the set as currently unavailable at time of research.",
    "verification_questions": ["Which connections, drivers, operating systems, and sample rates are supported by this exact revision?","What cables, mounts, power supplies, or licenses are included?","Is the current retailer listing new stock, demo stock, open box, or special order?","Is the item still in stock at the displayed price, and what is the complete delivered cost to the intended destination?"]
