Aiwa RV-1a 3 Ribbon mics/ original NHK case

Thank you for looking at my offerings! I live in Japan, and I’ve been collecting musical instruments and microphones for many years. 5 years ago, there were many vintage guitars available, but after COVID, vintage Japanese guitars became scarce.

 I also see that the chance of finding vintage Japanese microphones is becoming nearly impossible.

 Please consider this perhaps a final chance to fill your mic locker with 3 of the best of the best Japanese ribbon mics, the Aiwa RV-1a in their original NHK custom case.

Unbelievable, set of 3 NHK Aiwa RV-1A ribbon mics.

Excellent working condition. Always stored upright in the original NHK case.

Aiwa RV-1A NHK Ribbon Microphone

The RV-1A was an NHK-specification version of Aiwa's VM-17 microphone. It was Japan’s answer to the classic RCA 77D and is highly regarded by collectors for its superior engineering.

• Broadcast History: Specifically designed for NHK (Japan's national broadcaster), it was used extensively in television and radio.
• Key Features:
• • Polar Patterns: A multi-pattern (velocity ribbon) microphone featuring unidirectional, bidirectional, and omnidirectional modes.
  • Adjustability: Includes a 5-position low-frequency roll-off switch to manage the "proximity effect" common in ribbon mics.
  • Performance: Known for maintaining consistent frequency response and sensitivity even when switching directional patterns
