Siemens

Before Neve was Neve, before SSL was SSL, German recording technology led the world. Siemens — operating through their Siemens & Halske and later Siemens AG divisions — had been producing professional broadcast and studio equipment since the late 1940s. Their Sitral console frames, built around discrete modular components, became the standard in German broadcasting institutions and major European recording facilities throughout the 1950s and 1960s.

The Siemens module architecture is worth understanding in some detail, because it explains why these consoles sound the way they do. The V276 is the microphone preamplifier — a transformer-balanced, all-discrete amplifier with an enormous amount of headroom and a particular quality in the lower midrange. The W295 is the equaliser — a passive LC (inductor-capacitor) design using real inductors, not op-amp shelving approximations. The result is a phase-coherent EQ whose curves have a characteristic smoothness that active designs have never fully replicated.

The W295B specifically became the most-used Siemens EQ module in recording — it can be identified by its three rotary controls covering low shelf, mid peak, and high shelf frequencies. The V72 tube preamp, the V76 tube compressor, and the V275/V294 line amplifiers complete the signal chain of a typical Siemens studio console of this era.

The Siemens Sitral was the direct predecessor to everything that came after. Rupert Neve's early education in studio electronics was strongly influenced by German broadcast engineering. The modular concept — discrete components in a standardised frame that can be swapped, repaired, and reconfigured — became the design philosophy that Neve, API, and SSL all eventually adopted.
