From the seller: “During the 1980s Nakamichi made a very high quality field recorder and as a companion to it, made the CM 300. The mic features a 10db pad, 2 way high pass, 2 capsules(cardioid and omni) and a windscreen. These are perfect for using with vintage mixers without phantom power, because it runs off 9-12v of battery power. The battery has just been replaced and will be good for a few hundred hours. Also included is the original manual and case. The mic is near mint condition. It can take really subtle passages with almost no noise floor, and with high SPL sources it has a gooey natural compression.”
