SQA National 5 Music Technology: complete guide to technology concepts and equipment
A deep-dive SQA National 5 Music Technology guide to technology concepts: microphone types, polar patterns and placement; audio effects and processors (reverb, delay, chorus, flanger, distortion, EQ, compression) and their controls; the main equipment and signal path; and the key technological terms such as gain, clipping, sampling rate, bit depth, panning, sibilance and dynamic range.

Technology concepts is the audio-engineering knowledge tested in the National 5 Music Technology question paper, alongside the listening content. You need to know your microphones, effects, equipment and technical vocabulary well enough to answer scenario and description questions, and the same knowledge runs your practical recording. This guide maps the area; each part has its own answer page with worked questions.
Microphones
Two main types: the dynamic (rugged, handles loud sounds, no power needed - good for guitar amps, drums and live vocals) and the condenser (sensitive, detailed, needs phantom power - good for studio vocals and acoustic instruments). The polar pattern is where the microphone picks up: cardioid (front only, rejects the rear), omnidirectional (all directions) and figure-of-eight (front and rear, rejects the sides). Placement changes the sound too - close gives a strong, detailed tone (and bass through the proximity effect), distant captures more room.
Audio effects and processors
Know what each does and one control on each: reverb (space and echo; decay, room size, mix), delay/echo (distinct repeats; delay time, feedback), chorus (thickens one sound into many; rate, depth), flanger (sweeping jet swoosh; rate, depth), distortion (gritty tone; drive), equalisation (boosts or cuts frequency bands; frequency, gain, Q) and compression (evens out loud and quiet parts; threshold, ratio, attack, release).
Audio equipment and the signal path
The core gear: the mixing desk (combines signals into a balanced mix, with level, EQ, pan and effects per channel), the audio interface (converts audio between analogue and digital for the computer), the PA system (loudspeakers for an audience), monitors (accurate speakers for judging a mix), the amplifier (boosts a signal to drive speakers) and the DI box (plugs an instrument straight into the desk with a balanced signal). The signal path is the order the signal travels: source - microphone or DI - desk or interface - recorder/computer - monitors or PA.
Technological terms
The key vocabulary: gain (input level), clipping (distortion from too much level), sampling rate (how often a digital recording samples the sound) and bit depth (how precisely each sample is measured), latency (the small delay through a computer system), mono and stereo (one channel versus two with left-right width), panning (placing a sound across the stereo field), sibilance (harsh "s" sounds), plosives (popping "p" sounds) and dynamic range (the gap between quietest and loudest).
How this area is examined
Questions describe a scenario or play an effect and ask you to choose equipment, describe what something does, name a control, or diagnose and fix a problem. The reliable marks come from matching microphones to sources, telling apart easily confused pairs (reverb and delay, monitors and a PA, sampling rate and bit depth, clipping and deliberate distortion) and always pairing a problem with its remedy.
How to study this area
This area rewards precise technical vocabulary applied to real situations.
- Match microphones to sources. Drill dynamic-for-loud and condenser-for-detailed with reasons.
- Learn each effect and a control. Pair every effect with its job and at least one genuine control.
- Trace signal paths. Practise listing devices in the order the signal flows, source to playback.
- Define the terms exactly. Keep sampling rate and bit depth, mono and stereo, clipping and distortion clearly apart.
- Practise past papers. SQA past papers and marking instructions teach the scenario style and the wording markers reward.
