Morley HUMNO - NOISE ELIMINATOR CABLE

Morley Humno: a solution dedicated to mains noise issues

Morley is a well-known brand among musicians and technicians for its robust solutions designed for stage and studio use. With the Humno, the approach is clear: to offer a specialized accessory that tackles power supply noises (hum and buzz) before they get amplified, recorded, or broadcast. The Humno thus integrates as a practical tool in any environment where signal cleanliness is critical.

Who should use the Morley Humno and in which situations?

The Morley Humno is aimed at guitarists, bassists, keyboardists, DJs, sound engineers, videographers, and integrators who encounter interference related to power supply or grounding. It is particularly useful when playing on variable electrical installations (rehearsals, concert halls, events, studios) or when multiple devices are interconnected (PA systems, audio/video computers, powered monitors, broadcast systems, home theaters).

In practice, the Humno finds its place both in live sound reinforcement (front of house, monitors, powered systems) and in studio (recording, broadcast), or in fixed installations (conference rooms, theaters, places of worship, intercoms). It can also help reduce certain noise artifacts noticeable on video/AV chains when linked to the power line.

Filtering, installation, and operation: what the Humno changes daily

Filtering designed to reduce unwanted noise

The Humno is designed to filter the ground line from excess low voltage and current that can generate audio noise. The goal is to preserve a clean signal, with a clearer sound, particularly noticeable on clean tones, high-gain pickups sensitive to noise, or high-level broadcast systems.

Maintaining proper grounding

Key point: the Humno maintains proper grounding and is not a ground plug. It is not an accessory intended to "bypass" safety but a solution aimed at limiting the causes of hum and buzz that can travel back to your equipment.

Direct connection and instant status indication

Usage is intentionally simple: just connect the Humno to the power input of the problematic device. An integrated LED allows a quick check that the device is powered and operational, which is especially appreciated during installations or quick stage changes.

An accessory suited to many environments

Whether you want to clean up the power supply of a guitar amplifier, a bass amp, powered monitors, a DJ/karaoke system, an AV control room, or a home studio setup, the Humno aims to simplify troubleshooting: place it on the device causing issues to reduce unwanted noise as close as possible to its entry point.
