What unit is used to measure amplitude in audio signals?

Decibels (dB)

Which frequency range is generally considered as 'bass' in audio?

20 - 250 Hz

What is the primary use of a Direct Injection (D.I.) box?

To connect an instrument-level signal to a mic-level input

Which signal level is the strongest: Mic, Instrument, Consumer line, or Professional line?

Professional line level

What is the main difference between Loudness and SPL (Sound Pressure Level)?

SPL measures physical pressure; Loudness is how humans perceive volume.

What is one of the key advantages of balanced cables over unbalanced cables?

They help reduce noise through Common Mode Rejection (CMR).

Which type of connector is commonly used with balanced cables?

XLR.

A balanced cable generally has how many conductors?

3 conductors.

In parallel processing, where is the effect applied?

On a separate bus or auxiliary track.

Which of the following is a time-based effect: Reverb, Compressor, Gate, or Expander?

Reverb.

Which parameter on a compressor sets the point at which the compressor begins to reduce the signal?

Threshold.

What is an expander commonly used for?

To reduce low-level noise.

Which effect is typically used to create a sense of space and depth: Compressor, Delay, Gate, or Limiter?

Delay.

Which type of microphone is known for its durability and ability to handle high SPL?

Dynamic microphone.

What is the primary pickup direction of a microphone with a cardioid polar pattern?

From the front.

What does 'self-noise' refer to in microphone specifications?

The inherent noise produced by the microphone itself.

What does the S/N (signal-to-noise) ratio describe in a microphone?

The difference between the signal level and noise floor.
