You plug a dynamic microphone into your audio interface but get no signal. What is the most likely fix?
Answer: Connect it to a mic/XLR input and raise the preamp gain
Dynamic mics need an XLR mic input with preamp gain, and they do not require phantom power.
Which input on an audio interface is designed for the high-impedance, low-level signal from a passive electric guitar?
Answer: The Hi-Z / instrument (DI) input
A Hi-Z instrument input matches the high impedance of passive pickups to prevent tone loss.
What does the term 'gain staging' refer to in a signal chain?
Answer: Setting each stage's level so the signal is strong but never clips
Gain staging keeps levels optimal at every stage to maximize signal-to-noise ratio without clipping.
Your recording sounds distorted and the interface's input meter shows red. What should you do first?
Answer: Lower the input gain on the preamp
A red clipping meter means the input is too hot, so reducing preamp gain prevents digital distortion.
What is the typical order of analog signal flow when recording a condenser mic?
Answer: Mic → preamp → A/D converter → computer
The mic signal is amplified by the preamp, then digitized by the A/D converter before reaching the computer.
Phantom power (+48V) is required by which type of microphone?
Answer: Active condenser microphones
Condenser mics need +48V phantom power to charge their capsule and run internal electronics.
What does 'direct monitoring' on an audio interface accomplish?
Answer: It routes the input straight to the outputs to avoid latency
Direct monitoring sends the input to the headphone/monitor outs in hardware, eliminating round-trip latency.
