Switches and practical considerations Flashcards
What does a polar pattern switch on more expensive microphones do?
A polar pattern switch allows you to change between different capsules, offering different pickup patterns.
What is the function of an HPF (High Pass Filter) or rumble filter?
An HPF/rumble filter cuts all frequencies below a certain threshold, such as 100 or 150Hz, to eliminate unwanted low-frequency noise.
What does a pad switch do on a microphone?
A pad switch reduces the input signal by a set amount (e.g., 10dB) to avoid clipping at the microphone capsule, especially useful for high sound pressure levels (SPL).
When should you turn off phantom power?
Phantom power should be turned off for ribbon microphones, as it can damage them.
What is the purpose of phantom power on audio interfaces?
Phantom power is used to power condenser microphones and DI boxes, which require an external power source to function.
What is the function of a shock mount in microphone setup?
A shock mount is used to prevent vibrations from traveling up the mic stand, which could introduce rumble or unwanted noise into the recording.
What is the purpose of a pop shield?
A pop shield helps reduce plosive sounds (e.g., “p” and “b” sounds) in recordings, which can cause distortion. Alternatively, you can move away from the microphone to reduce plosives.
Why is it important to avoid using phantom power with ribbon microphones?
Phantom power can damage ribbon microphones, as they are designed to operate without it and are sensitive to voltage.
What kind of microphones typically require phantom power?
Condenser microphones typically require phantom power to operate, as they need an external power source for their internal circuitry.
How does a pop shield help when recording vocals?
A pop shield helps reduce plosive sounds (such as “p” and “b” sounds) that can cause distortion or clipping in the recording, ensuring cleaner audio.
