Abbey Road 273

NT$ 29,000

 2-Channel | Preamplifier

Abbey Road 273 preamplifier is a dual-channel vintage-style microphone, line, and instrument preamplifier. The signal path uses only discrete components such as resistors, capacitors, and transistors. Both the input and output are balanced using two different transformers, each optimized for its purpose. This is the manufacturing method of audio components before the advent of integrated circuits. The circuit used in the Abbey Road 273 preamplifier is similar to the preamp section of the classic 1073 module, with warm, powerful, sweet, and musical sound characteristics. These classic features have been heard in countless recordings over the years, and it is a versatile sound that excels in most sound sources and genres. The essence of this sound is now available at an astonishingly low cost, making it accessible to almost everyone.
