DJ Mixing MCQ 5 — Questions and Answers
Question 1: What does 'sidechain compression' do in a DJ mix context?
- Compresses the master output when the DJ speaks into the microphone
- Causes one audio signal's volume to duck down when triggered by another signal, commonly used to let the kick drum punch through the mix (Correct answer)
- Chains multiple compressors together on the same channel
- Applies compression only to the side (stereo width) channel
Correct answer: Causes one audio signal's volume to duck down when triggered by another signal, commonly used to let the kick drum punch through the mix
Sidechain compression makes one element (e.g., a bassline) automatically reduce in volume whenever another element (e.g., the kick drum) plays, creating a pumping effect.
Question 2: When is it appropriate to use the 'sync' button in a DJ performance?
- Never — using sync is considered cheating by all professional standards
- As a tool to assist with tempo matching, particularly when juggling multiple tracks or when hands are occupied with other performance elements (Correct answer)
- Only when mixing vinyl records
- Only to sync lighting rigs to the music
Correct answer: As a tool to assist with tempo matching, particularly when juggling multiple tracks or when hands are occupied with other performance elements
Sync is a legitimate tool that handles tempo alignment, freeing the DJ to focus on creative elements like EQ, effects, and crowd interaction.
Question 3: What is 'acapella mixing' and what skill does it primarily test?
- Mixing tracks without using headphones
- Layering a vocal-only track over a different instrumental track, requiring precise pitch and tempo matching (Correct answer)
- Mixing only vocal tracks without any instrumental music
- Using only voice commands to control DJ software
Correct answer: Layering a vocal-only track over a different instrumental track, requiring precise pitch and tempo matching
Acapella mixing places an isolated vocal over a different beat, demanding accurate harmonic and BPM alignment so the vocal sits naturally in the new context.
Question 4: What is the 'Camelot Wheel' used for in DJing?
- A wheel-shaped controller for scratching
- A system that maps musical keys into numbers and letters to simplify harmonic mixing decisions (Correct answer)
- A BPM calculator for tempo-matching tracks
- A visual representation of waveform shapes
Correct answer: A system that maps musical keys into numbers and letters to simplify harmonic mixing decisions
The Camelot Wheel (or Camelot Sound System) assigns each musical key a code (e.g., 8A, 8B) so DJs can quickly identify which keys mix harmonically without music theory knowledge.
Question 5: What is the advantage of using a 'pre-fader listen' (PFL) cue in a DJ mixer?
- It allows the DJ to hear the master output at a lower volume
- It lets the DJ monitor an incoming track in headphones independently of the fader position, so it can be cued up privately before the audience hears it (Correct answer)
- It applies a pre-set EQ to the incoming track automatically
- It sends the fader signal to the recording output before it reaches the master
Correct answer: It lets the DJ monitor an incoming track in headphones independently of the fader position, so it can be cued up privately before the audience hears it
PFL cues the channel audio to the DJ's headphones regardless of fader or crossfader position, allowing silent preparation and beatmatching of the next track.
Question 6: What does 'rekordbox' (Pioneer DJ's software) primarily provide for DJs?
- A social media platform for sharing DJ sets
- Track analysis, beatgrid editing, cue point management, and library organization for use with Pioneer CDJ players (Correct answer)
- A streaming service exclusively for DJs
- Hardware firmware updates for Pioneer mixers
Correct answer: Track analysis, beatgrid editing, cue point management, and library organization for use with Pioneer CDJ players
Rekordbox is Pioneer DJ's ecosystem software for preparing, analyzing, and organizing music that can then be exported to USB for use on CDJ media players.
Question 7: Which of the following describes a 'transformer scratch'?
- A scratch technique that transforms the pitch of a record over one bar
- Rapidly toggling the channel fader or crossfader on and off while moving the record to create a choppy, staccato sound (Correct answer)
- A scratch performed during a tempo change
- Using a transformer plug to convert scratch audio to MIDI
Correct answer: Rapidly toggling the channel fader or crossfader on and off while moving the record to create a choppy, staccato sound
The transformer scratch involves quickly opening and closing the fader while moving the record forward, creating a series of short, punchy sound bursts.
