allanalog

All-analog, or all-analog design, denotes systems that operate with continuous-time, continuous-amplitude signals and do not rely on digital sampling or discrete-time processing in the signal path. In practice, devices marketed as all-analog may include digital controls or indicators, but the primary signal processing path remains analog.

In electronics and audio, all-analog implementations include vinyl playback, analog tape, analog synthesizers, as well as analog filters, preamplifiers, power amplifiers, and other non-digital signal chains. They are contrasted with digitally processed or digitized chains that incorporate analog-to-digital converters, digital signal processing, or digital control loops.

Advantages of all-analog designs are often cited as faithful, continuous signal reproduction and low latency, along with a perceived warmth associated with analog circuitry. Disadvantages include sensitivity to temperature and component tolerances, drift over time, higher maintenance, potential noise and distortion from analog components, and less flexibility for precise, repeatable settings without physical adjustments.

Historically dominant in early electronics, all-analog technology remains prevalent in niche markets such as high-end audio, tape and vinyl workflows, and certain laboratory instruments. In modern contexts, products marketed as all-analog frequently pair an analog signal path with digital interfaces for control or monitoring, retaining the branding while using digital technology for non-signal tasks.
