Out of Austin, Texas came a graphic EQ that quietly became the studio standard while flashier rivals grabbed the magazine covers. The White Instruments 4400 skips the fragile faders and hands you 28 rotary knobs, one per third-octave band, so your settings survive transport, gravity and clumsy elbows. Inside, every band is a hand-tuned pair of inductors and capacitors: passive, low noise and almost impossible to kill. The payoff is a narrow, surgical Q with very little spill between neighbouring bands, and a tone engineers reach for when they want warm and unmistakably analogue. This unit is wired for South African mains and ready to rack. Put it on vocals, bass or a cluttered mix and it behaves less like a tone control and more like a precision instrument.

FEATURES & PROS:

• 28 rotary bands: one knob per third-octave band from 31.5 Hz to 16 kHz, so settings stay put and recall is instant.
• L-C inductor design: passive, hand-tuned filters that add no noise and shrug off decades of use.
• Narrow surgical Q: lift or cut one frequency without smearing its neighbours, ideal for tracking and fixing problem mixes.
• Warm analogue character: the inductor circuit delivers the thick, musical tone players chase.
• Three outputs: distribute the signal, or biamp and triamp using the powered crossover socket.
• Adjustable band limiting: built-in high and low-pass filters tame the extremes before they cause trouble.
• Silent EQ in/out: front-panel bypass for honest before-and-after comparison.
• Plug and play in SA: built-in three-prong South African mains, no step-down adapter circus.
