Neve 1272 Schematic [best] -

At the heart of the Neve 1272 schematic is the BA283 gain stage. This circuit board is the engine of the Neve sound, utilizing discrete, Class A transistor circuitry. Specifically, the 1272 typically employs a BA283AV configuration, which consists of a preamp stage (the "AM" portion) and an output amplifier stage (the "NV" portion). Unlike a 1073, which uses three gain stages to reach high gain levels for quiet microphones, the stock 1272 schematic only utilizes two gain stages. This limitation meant that in its original console environment, the 1272 provided a fixed amount of gain, usually around 35 to 40 dB, sufficient for its role as a summing amplifier but inadequate for a versatile microphone preamp.

When audio engineers speak of the "British" or "Transformer-Balanced" sound of the 1970s, one name dominates the conversation: . While the Neve 1073 preamplifier has attained mythical status (often selling for $4,000+ per channel), the Neve 1272 operates as its fascinating, slightly less famous, but equally potent sibling.
