CRT Power Off

How it's made

Source

opening power contacts make a 1-7 ms filtered noise pop; charged glass releases small static grains as high voltage drains. Separate seeded noise streams excite each electrical layer.

Body

the switch excites damped cabinet modes near 210, 530 and 1180 Hz, T60 45-110 ms; cabinet size lowers their tuning. No room reverberation is baked into the effect.

Layers

flyback vibration starts near 15.6 kHz, bends to 10.8 then 7.2 kHz as regulation fails, and dies within 0.20-0.42 s. A quieter half-frequency mechanical component tracks the collapse.

Envelope

rounded 2-7 ms onsets avoid unintended clicks; static darkens from 6.5 to 1.4 kHz in 0.22 s. The 60/120/240 Hz transformer hum fades over 0.62-1.04 s as stored supply energy drains.

Events

a main discharge at 18-30 ms precedes sparse 1-4 ms glass ticks, with their rate and strength falling during the first 0.45 s. All layers reach zero before the final silence.

Variation

seeded contact timing, cabinet detuning and whine flutter; macros control cabinet size, discharge strength, flyback level and drain time. Presets span portable, console, dusty and soft sets.
