Review: Classic Shure Microphone - I have this and the 565sd. These mics are simply fantastic! They are a bit brighter that the sm57 and sm58, and this is very favorable for those who think those two mics are a bit dull. The classic chrome styling gives this a great retro look that continues to stand the test of time. I mean this mic is basically unchanged for more that 60 years! Congratulations Shure for making such wonderful mics that are still industry standards today. I personally do not care for switches on microphones, but you have the ability to lock these into the on position. Overall, I'm very happy I bought this mic and it will be staying with me from now on. Review: This microphone is fun for Freddy Mercury fans who want to use the ... - This microphone is fun for Freddy Mercury fans who want to use the mic he was known for using while live. I have been on stage many times with a Shure SM58 and was served well by it, but I wanted a mic with a little less bass while using the proximity effect, and this seems like it did that for me. It is the predecessor to the SM58 and both looks and sounds sort of like it. I wanted this microphone for its very distinctive sound profile and was happy with it. It seems very durable, the switch is well designed and is totally silent in many circumstances, but can be locked into the "on" position. My m-Audio Fast Track Pro digital audio interface was not working well with this mic due to low output causing me to have to raise the gain to a level that caused a lot of background noise. I solved the problem to my satisfaction with a Cloudlifter Mic Activator, which is a preamp that is phantom powered and small enough to tape to a mic stand. I could then lower the gain on the audio interface to get a cleaner sound. After this setup was achieved, I was totally happy with this microphone. ## Features - Exceptionally uniform cardioid pattern minimizes feedback - Selectable dual-impedance operation - Silent magnetic reed on/off switch with lock option - The predecessor to the SM57 - A favorite for instrument pickup and recording, the 545SD can also be used on lecterns in public address systems - Includes Shure A25D microphone clip ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002JEUSW | | Batteries | 1 Lithium Ion batteries required. | | Best Sellers Rank | #12,777 in Musical Instruments ( See Top 100 in Musical Instruments ) #57 in Multipurpose Dynamic Microphones | | Color Name | silver | | Customer Reviews | 4.5 4.5 out of 5 stars (235) | | Date First Available | July 16, 2004 | | Frequency Response | 20 KHz | | Global Trade Identification Number | 00042406051873 | | Hardware Platform | PC | | Impedance | 150 Ohms | | Is Discontinued By Manufacturer | No | | Item Weight | 15.2 ounces | | Item dimensions L x W x H | 10.1 x 5 x 3.4 inches | | Item model number | 545SD-LC | | Manufacturer | Shure | | Material | Metal | | Material Type | Metal | | Microphone Form Factor | Microphone Only | | Number of Batteries | 1 Lithium Ion batteries required. | | Number of Channels | 1 | | Power Source | Corded Electric | | Product Dimensions | 10.1 x 5 x 3.4 inches | | Signal-to-Noise Ratio | 78 dB | | Size | 174.14 cubic inches | | UPC | 042406051873 | ## Product Details - **Brand:** Shure - **Color:** silver - **Compatible Devices:** Personal Computer - **Connectivity Technology:** Wired - **Connector Type:** lc - **Included Components:** Microphone Clip - **Model Name:** language _ tag - **Polar Pattern:** Unidirectional - **Recommended Uses For Product:** Voice Recording, Video Recording, Speech - **Special Feature:** Clip ## Images ![Shure 545SD-LC Cardioid Dynamic High or Low Z On-Off Switch - Image 1](https://m.media-amazon.com/images/I/41+2CuhlnoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Classic Shure Microphone *by M***. on May 18, 2025* I have this and the 565sd.
