## Overview

The Shure 545SD-LC is a dynamic handheld microphone featuring a unidirectional cardioid pattern and selectable dual-impedance operation. Equipped with a silent magnetic reed on/off switch with lock, it delivers professional-grade sound clarity and feedback rejection. Renowned as the predecessor to the SM57, this metal-bodied classic remains a trusted choice for instrument recording and public address, combining vintage aesthetics with versatile performance.

## Description

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.

Review: このマイクを使った事がなかったので、先っちょがグラグラすること知らなかったので、不良品だと思ってって２回も交換お願いしました。ごめんなさい。ちゃんとシュアのホームページを読むとそういう製品なことがよくわかりました。少し慣れがいるのかもしれませんが、スクリューをゆるめてコネクターをペンチで引き出し（力いらない）、上下を逆に繋ぎ出すだけで、とんでもなくハイパワーになります。そのままでもグリーンバレット並み。ハーモニカマイクにはとてもよいと思います。ただ、ボリュームコントロールがないので、アンプとの立ち位置が問題かも。前に立ってはダメ、昔のフェンダーアンプのようにステージの前にアンプを置いて、スイッチは切ってアンプのボリュームをいじった方が良いかもです。desertcartさんありがとう。
Review: 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.
