Analog audio engineering, built for working studios

lhd designs professional analog audio equipment with a single focus: signal integrity, low-noise circuit topology, and hardware that holds up through continuous commercial recording and mastering sessions.

Every component is chosen for its behaviour in a real circuit, not its datasheet alone. Units are hand-wired, calibrated against reference measurements, and tested on the bench under sustained load before they leave the workshop.

Collaboration with working engineers shapes the final ergonomics: control placement, metering, and connections are refined until they suit the way a session actually runs.

We build around how analog circuits actually respond: the signal path, the gain structure, and the way a stage colours or preserves a signal. Simulation is a tool for checking a design, not a substitute for listening to and measuring real hardware.

The result is equipment with a low-noise foundation and a clear purpose: dependable hardware for studios and production teams who need the signal chain to behave predictably, session after session.
