K Series Speakers

When a company known for its roadworthy amplifiers comes out with a self-powered speaker line, the industry takes notice. While QSC’s K Series was not its first venture into the powered speaker market, the line has gone on to become its most successful speaker offerings and a decade later, is well into its second generation, the K.2.

Even in the pro audio world, Crane Song founder Dave Hill is hardly a household name. But starting back in the 1980s, his designs were the driving force behind many of Summit Audio’s most successful studio products, including the EQP-200 Dual Program Equalizer and the DCL-200 Dual Tube Compressor. Later setting out on his own, he founded Crane Song to create pristine-quality electronics for recording, mastering, and live sound engineers.


Long before the term “project studio” was coined, Tom Scholz (founder of the band Boston) built a basement studio to record his own music, including his band’s debut album. An engineer with a master’s degree from MIT, he created much of his own gear, including what was to become the Scholz Rockman, a pocket-sized box that offered compression, distortion, stereo chorus and delay effects for guitar — effectively becoming a complete studio or pedalboard in a miniature package.

TR-808 Drum Machine

It’s hard to believe that a 40-year-old drum machine continues to have a profound impact on the sound of modern music, but the 1980’s Roland TR-808 is such a device. One of the first drum boxes that allowed users to create and store beats and patterns, the TR-808 found a receptive audience, especially with its intuitive, easy to use onboard sequencer. Unfortunately, as drum samples became affordable and more “realistic,” the TR-808, with its analog-synthesized percussion sounds was discontinued.

Cooper Time Cube

In the days before digital, achieving delay effects either required “bucket brigade” analog circuits, tape delay or simply sending audio down a long pathway (hallway, stairwell, etc.) and capturing the result with a microphone at the other end.

Seeking an alternative, in 1971 Bill Putman of Universal Audio/UREI and Duane Cooper collaborated to create the first mechanical delay device which routed audio down a garden hose housed in an enclosure with microphones placed at different points, yielding a choice of 14, 16 or 30 milliseconds of delay time.
