A mixer is an audio processing device that accepts multiple input signals, allows independent level adjustment and routing of each channel, and produces a combined output (stereo or multi-channel). Its parameters include: number of input channels, number of bus outputs, signal path topology (analog through op-amp circuits or digital through DSP processing), channel strip features (EQ, gating, compression per channel), and monitoring capabilities. The device persists as physical hardware with knobs, faders, displays, and connections, or as software implementing the same functional architecture. Mixers operate by summing signals through additive or matrix-based routing while preserving each channel's adjustability.

Definition
Why it is in scope
An electronic device that combines, routes, and adjusts multiple audio signals through faders, knobs, and switchable paths, built through analog or digital signal-processing circuits, built to persist as a central instrument in live sound, recording studios, and broadcast facilities.

Mixer is an audio processing device built and maintained for the sake of audio processing: it combines, balances, and routes multiple audio signals through additive or matrix-based summing while preserving per-channel adjustability, enabling the core operations of audio production. Servant points at master per Law 8d.

A mixer's purpose is to combine, route, and process signals. Remove signal and the mixer has no function — it stops operating entirely. This is object-level dependency: signal is the domain in which a mixer operates, not a meta-level condition. Removal test passes.

A mixer is a specific kind of instrument: it is an electronic device that an audio engineer operates to shape sound, with faders, knobs, and switches that the user manipulates directly. In studio and live-sound contexts, the mixing console is routinely called 'the instrument' — the primary tool through which the engineer expresses creative control.
