Sennheiser MKH 50-P48 Supercardioid RF Condenser Microphone

Reference Indoor Dialogue & Studio Audio: Sennheiser MKH 50-P48

The Sennheiser MKH 50-P48 is the premier supercardioid microphone trusted by boom operators, re-recording mixers, and production sound recordists for capturing crystal-clear indoor dialogue in feature film, television, and studio environments.

Unlike traditional shotgun microphones that create comb-filtering artifacts when acoustic reflections bounce off indoor walls and ceilings, the MKH 50 utilizes a true supercardioid pickup pattern with high off-axis attenuation. Its RF condenser capsule delivers clean, uncolored vocal timbre with exceptionally low self-noise and immunity to moisture and high humidity. Available now in our Sennheiser pro audio store catalog, the MKH 50-P48 is an indispensable asset for critical sound stages and field recording rigs.

Key Features & Pro-Level Advantages

• Superior Indoor Sound Isolation: Pure supercardioid polar pattern provides high off-axis attenuation without the phase coloration typical of interference tube shotguns in reverberant rooms.
• Moisture-Resistant RF Condenser Circuit: Inherent RF transducer architecture makes the capsule immune to humidity, condensation, and temperature flux.
• Switchable Low-Frequency Roll-Off: Built-in high-pass filter eliminates proximity effect thumps and low-end structural rumble at the source.
• Switchable -10 dB Attenuation Pad: Prevents preamp stage clipping when recording dynamic acoustic instruments or loud vocal performances.
• Ultra-Low Self-Noise (12 dBA): Exceptionally quiet circuit topology preserves subtle acoustic detail and quiet speech without noise floor buildup.
• Balanced Symmetrical Capsule Design: Symmetrical acoustic impedance ensures ultra-low distortion and high signal output levels.
