One-click noise reduction, quiet recording. Low noise and easy to carry. Adjustable microphone signal, attenuator Smart appearance and convenient installation. The smart appearance design can be easily installed on the microphone cannon seat without extra burden. It is also very convenient to carry. Reduce microphone sensitivity. Reduce noise collection. Small appearance and professional circuit design. Quickly adjust the sensitivity of the microphone, so as to narrow the range of sound picked up by the microphone and reduce the collection of environmental noise. Three-gear adjustment is suitable for various microphones and environments. MA-123 is designed with -10, -20 and -30DB adjustment switches, which can quickly adjust the microphone sensitivity according to the microphone and environmental noise, reduce sensitivity and reduce sound collection. When picking up high-volume sound sources, reducing sensitivity can effectively prevent sound overload during recording. Plug-and-play is practical and convenient. MA-123 is designed by Kaye male and female, which can be directly connected with microphone and cannon wire, and can be used after connection without extra power supply, which is very convenient. Nickel-plated cannon male plug. Gold-plated canon pin has fast signal transmission and reduces signal loss. Nickel-plated card for female plug and nickel-plated card for female shell are rust-proof, stable and durable. The metal shell is durable. MA-123 adopts aluminum alloy shell design, which can effectively reduce electromagnetic interference. Black painting process is simple and generous. MA-123 is an adjustable microphone signal attenuator. It outputs extraordinary subtle details and provides high-definition sound quality. The design of -10DB, -20DB and -30DB with different attenuation levels ensures stable operation and en
