Home / Neumann 503909 Mounting Adaptor Plate LH 47 Mounting adaptor plate to fit the LH 43, LH 45 or LH 46 with LH 12, LH 15, LH 25, LH 26, LH 28, LH 29, LH 38, LH 45, LH 61 and LH 80.
The "Universal Link" for Professional Rigging
The LH 47 is a critical component for complex studio installations, particularly in immersive audio (Dolby Atmos®) and broadcast setups. Its primary purpose is to allow different generations and types of Neumann mounting hardware to "talk" to one another. Whether you are suspending a KH 310 from a telescopic ceiling mount or attaching a KH 120 II to a structural wall plate, the LH 47 provides the standardized mechanical interface needed to ensure a safe, stable, and perfectly aligned monitoring position.
Industrial Stability & Safety:
Engineered in Germany to Neumann’s rigorous standards, the LH 47 is constructed from heavy-duty steel. Despite its compact profile, it boasts a massive maximum load capacity of 65 kg (143.3 lbs), which is nearly double the weight of Neumann’s heaviest midfield monitors. This provides an exceptional safety margin, essential for overhead installations in high-traffic recording or post-production facilities.
Unmatched Modular Flexibility:
The LH 47 is designed to fit a "Cylinder-Shaped Holder" (Holder F) found on several Neumann master mounts. This enables a truly modular workflow where you can mix and match hardware to suit your room’s specific architectural needs. It serves as the mounting bridge for an extensive list of LH accessories, including:
Brackets: LH 12, LH 15, LH 25, LH 26, LH 38, LH 61, and LH 80.
Stand Adapters: LH 28 (35mm) and LH 29 (TV-Spigot).
Master Mounts: LH 43 (Surface), LH 45 (Wall), and LH 46 (Ceiling Drop).
Precision Installation:
The plate is designed for "tool-precise" alignment. It features a secure locking mechanism involving a locking ring and Allen head bolts that, when tightened to the recommended 15–20 Nm torque, creates a rigid bond between the monitor and the mounting structure. This rigidity is vital for maintaining acoustic neutrality, as it prevents the hardware from vibrating or resonating at high sound pressure levels.
Universal Bridge: Connects master mounts (LH 43/45/46) to speaker brackets and stand adapters.
High Load Capacity: Rated for up to 65 kg (143.3 lbs) for maximum studio safety.
Heavy-Duty Steel Build: Provides industrial-strength durability and acoustic stability.
Locking Ring Mechanism: Ensures a non-slip, vibration-resistant connection.
Professional Aesthetics: Durable powder-coated finish in Black (RAL 9005).
Wide Compatibility: Recommended for use with KH 80 DSP, KH 120, KH 150, and KH 310.
