This is a set of a SHURE wireless microphone and a dedicated in-line preamplifier. I was using it wired (TA4F to XLR conversion) with RPM instead of wireless. (Phantom power required) This microphone can also be used as a wireless microphone by purchasing a wireless system. I used it for about six months in live performances, but I am selling it because I no longer need it. The RPM has some scratches, but the microphone itself is generally in good condition. However, please refrain from purchasing if you are sensitive to used items. Also, returns are not accepted to prevent replacements or removal of parts. Included accessories: ・Dedicated microphone pouch ・Windscreen (taken out of the case for photography, but otherwise unused) Microphone specifications: ■Wireless microphone ■For wind instruments ■Polar pattern: Cardioid ■Frequency response: 20Hz～20kHz ■Maximum sound pressure level: 143.5dB SPL ■Connector: Switchcraft TA4F ■Dimensions/Weight: Microphone head φ10mm, 65g (microphone part) ■Cable length: 1.6m Excerpt from the SHURE official website: WB98H/C ◯Overview The WB98H/C, the wireless version of the BETA 98H/C, is a cardioid condenser premium instrument microphone that can be easily attached to the bell of wind instruments or the rim of percussion instruments. ◯Details Transformerless preamplifier circuit improves linearity across the entire frequency range. Achieves high gain with reduced feedback and excellent separation from unwanted sound sources. High maximum sound pressure level (SPL) allows it to handle extremely high sound pressure levels from wind instruments, woodwind instruments, percussion instruments, etc. Equipped with a high-flexibility cable (1.6m) with a 4-pin mini connector, allowing it to be used with a wireless bodypack transmitter (WB98H/C only).
