sE Electronics RN17-CARD-CAP - Cardioid Microphone Capsule for sE Electronics RN17

sE Electronics RN17-CARD-CAP - Cardioid Microphone Capsule

The cardioid capsule for the sE Electronics RN17 small-diaphragm condenser microphone combines Rupert Neve’s legendary acoustic transparency with a polar pattern that efficiently rejects noise from the sides and rear. Perfect for capturing direct sound sources—vocals, acoustic guitars, drum overheads, or a string section—it maintains the extended 20 Hz to 20 kHz response and preserves the warmth and clarity characteristic of the hand-wound transformer. A bayonet mount facilitates quick, tool-free capsule changes and preserves the integrity of the RN17’s original shockmount.

Main features

• Compatibility: Interchangeable capsule for sE Electronics RN17 microphone.

Product benefits

• Superior rejection of ambient noise and leakage from other instruments, thanks to the cardioid pattern.
• Linear and extended response that faithfully reflects the sound source without coloring.
• Integration with the hand-wound transformer for a warm, full and full-bodied sound.
• Bayonet mount that speeds up capsule changes in multi-format sessions.
• Sturdy and durable construction, suitable for studio and touring.

Use cases

• Solo voice and choirs: Clear and defined projection, with minimal feedback.
• Acoustic instruments: Guitars, pianos and strings, captured with detail and naturalness.
• Overheads and percussion: Balanced stereo imaging and realistic dynamics.
• Outdoor Recording: Main source isolation, ideal for filming and field recording.

Frequently Asked Questions

• Do you need tools for replacement? No, the bayonet system allows for quick and easy removal and insertion.
• Does it maintain the same self-noise as the factory cardioid version? Yes; the 18 dB(A) value is identical to that of the original capsules included in the stereo pair.
• Is it compatible with standard RN17 shockmounts? Absolutely; it retains the mounting and damping designed for the RN17.
• Does it require phantom power? Yes; 48 V phantom power according to IEC 61938.
