People in the circuit

Alex Cooper

Console designer, Midas and Klark Teknik

Major contribution

Alex Cooper designed the Midas XL4 and contributed circuitry and control concepts to subsequent analogue and digital live mixing consoles.

Alex Cooper joined Klark Teknik in 1979 and progressed from testing into console development. He helped build and debug the XL3 prototype, which incorporated some of his circuits, and went on to design the Midas XL4.

For the XL4, Cooper reworked the microphone amplifier and equalization circuitry with particular attention to overload behavior. His later work included the Heritage consoles and contributions to the XL8 and PRO6 digital systems, extending his involvement from analogue signal paths into digital live-sound control.
