Classic Unidyne® Instrument

The predecessor to the SM57, The 545SD Classic Unidyne® Instrument Microphone is a dual-impedance, unidirectional, dynamic microphone.

Shipped connected for low-impedance operation, the 545SD features a silent magnetic reed on/off switch with lock-on option. A favorite for instrument pickup and recording, the 545SD can also be used on lecterns in public address systems
  • 545SD-LC Cable not included

Features
  • Exceptionally uniform cardioid pattern minimizes feedback
  • Selectable dual-impedance operation
  • Silent magnetic reed on/off switch with lock option
  • Cardioid dynamic
  • Frequency response: 50 to 15,000 Hz

Specifications
  • Type : Dynamic
  • Frequency Response : 50 to 15,000 Hz
  • Polar Pattern : Cardioid (unidirectional)--uniform with frequency, symmetrical about axis
  • Impedance
    Dual. Microphone rating impedance is 150 ohms (250 ohms actual) for connection to microphone inputs rated at 19 to 300 ohms and "High" for connection to high-impedance microphone inputs. Wired for low impedance as supplied. To change impedance, see sections on lmpedance Selection and Connections in User Guide.
  • Output Level (at 1,000 Hz)
    Open Circuit voltage*
    Low : -58.0 dB (1.3 mV)
    High : -35.0 dB (17.6 mV)
    *0 dB = 1 volt per Pascal (1 Pa = 94 dB SPL)
  • Polarity : Positive pressure on diaphragm produces positive voltage on pin 2 (with respect to pin 3).
  • Switch : Built-in magnetic reed on/off switch with lockplate.
  • Cartridge Shock Mount : Internal rubber vibration-isolator
  • Swivel Adapter : Positive action, adjustable through 90 degrees from vertical to horizontal, permits easy removal for handheld use, suitable for mounting on stand with 5/8"- 27 thread
  • Case : Chrome-plated die casting with ARMO-DUR® grille and stainless steel screen
  • Dimensions : See User Guide
  • Net Weight (less cable) : 255 grams (9 oz)
