SHURE 545SH-LC Unidyne III Dynamic Microphone - Clearance

SHURE 545SH-LC Unidyne III Dynamic Microphone - Sale as is where is.

The Shure 545SH-LC is a vintage unidyne III cardioid dynamic microphone featuring a built-in swivel mount ("pistol grip" style), an on/off switch, and "less cable" (LC designation meaning it shipped without a cable). It is a close relative of the legendary Shure 545 series and the predecessor/cousin to the iconic SM57

Overview & History

• Design: Features a satin-chrome and black finish with a built-in swivel mount designed to attach easily to floor or desk stands.
• Era: Produced from the 1970s through the late 1980s (initially made in the USA, later manufacturing moved to Mexico before it was eventually discontinued)
• Core Sound: Uses the same classic Unidyne III dynamic cartridge design that gives the SM57 its punchy, mid-forward, and reliable sound signature, making it a favorite for vocals, instrument recording, and broadcasting.

Key Specifications

• Transducer Type: Dynamic
• Cardioid (unidirectional)
• Switch: Built-in on/off switch on the lower handle
• Connection: Standard XLR output (later models/variants; some very early 545 variants used screw-on Amphenol connectors, but the 545SH-LC utilizes standard locking connections)
