Q

What microphones have a high impedance output?

🔍 Key Concepts

• Difference between crystal and dynamic microphone construction • What impedance means in simple electrical terms (high vs low impedance sources) • Typical use of high-impedance microphones in older or simple radio/PA equipment

💭 Think About

• Think about which microphone type produces a relatively small current and is more sensitive to the type and length of cable used • Consider which microphone type more often needs a matching transformer to connect to standard low-impedance modern audio inputs • Ask yourself: in basic radio communications gear, which microphone type was traditionally known for being high impedance?

✅ Before You Answer

• Review which microphone element (crystal vs dynamic) behaves more like a voltage source with very little current • Recall that most modern professional audio systems are designed around low-impedance dynamic microphones • Eliminate any choice that suggests all types share the same impedance, or that none can be high impedance, and focus on the one most commonly associated with high impedance outputs
