Neve 1272 Schematic

The Neve 1272 schematic is a classic Class A line amplifier circuit, originally used as a bus summing amp in vintage Neve consoles. While it lacks the third gain stage of the 1073 (limiting it to ~50dB of gain), its identical core components—the BA283 amplifier card and LO1166 output transformer—make it a premier choice for DIY mic preamp projects.  Core Schematic Components 

The Neve 1272 holds a unique place in the pantheon of pro audio. It is a circuit surrounded by both incredible hype and intense technical debate. If you have ever looked at a vintage Neve console or researched DIY preamps, you have likely come across this famous number. Neve 1272 Schematic

• The 1073 is a 1272 preamp with an EQ section attached.
• The 1272 is the preamp section only (usually).
• The "Retrofit" Era: In the 90s and 2000s, technicians realized that racked 1272 modules could be modified to accept an external EQ or be wired as a standalone preamp. However, purists argue that the output transformer winding on a true 1272 differs from a 1073, making the 1272 slightly cleaner or "faster" sounding than the thicker 1073.

Smooth Highs: Even when pushed, the discrete Class A design rounds off harsh transients. The Neve 1272 schematic is a classic Class

• TR1 (Input transistor): Biased by a 10k resistor from the collector to the +24V rail. The base receives signal from the transformer secondary. The emitter has a 5.6R resistor to ground (bypassed by a massive 470uF capacitor for full AC gain).
• TR2 (Second stage): Directly coupled from TR1’s collector. It’s another common-emitter stage. Feedback from the output of the BA283 is fed back to the emitter of TR1 via a precision resistor network.

Arthur walked up to the microphone. He didn’t sing. He didn’t play a guitar. He simply spoke into the massive open room. "This was the sound of 1974," Arthur whispered. "Goodbye." The 1073 is a 1272 preamp with an EQ section attached

The Go to product viewer dialog for this item. is a classic discrete, Class-A bus amplifier from the 1970s Neve 80-series consoles. While originally designed as a line amplifier, it has become famous in the DIY and boutique audio world because it can be modified into a high-quality microphone preamplifier using the same "building block" components found in the legendary Neve 1073. 1.
