Cranborne Audio N22H – Reference Headphone Amplifier with C.A.S.T. System

The Cranborne Audio N22H is a modern reference-class headphone amplifier designed for the most demanding users. It offers excellent sound quality, unmatched configuration flexibility, and the innovative C.A.S.T. signal transmission system that revolutionizes audio distribution in studios and live setups. Its robust metal housing and compact dimensions also make it a perfect mobile solution for engineers and musicians on the go.

Exceptional Sound and Advanced Features

The N22H is based on the proven audio path of the Cranborne Audio 500R8 interface. It delivers a flat frequency response from 0.8 Hz to over 250 kHz and features ultra-low distortion (<0.0009% THD+N), ensuring precise detail reproduction – crucial for mixing, mastering, and critical listening. With up to 950 mW per channel output power, the N22H easily drives high-impedance headphones as well as low-impedance in-ear monitors (IEMs).

Switchable high- and low-power modes allow for optimal performance based on the headphones in use. A custom logarithmic headphone volume control provides fine-tuned output adjustment without drastic level jumps.

C.A.S.T. System – The Future of Analog Audio Distribution

C.A.S.T. (Cat 5 Analogue Snake Transport) is a unique Cranborne Audio technology that transmits analog audio signals and 48 V phantom power via a single shielded Cat 5e, 6, or 7 cable. This enables the headphone mix to be delivered to the N22H while also routing mic/line signals back to your interface – a fully analog solution over a single affordable cable. With a range of up to 100 meters and compatibility with other Cranborne Audio devices, the N22H becomes the heart of a professional and flexible audio system.

Perfect for Versatile Use

The N22H is ideal for sound engineers, musicians, and producers who demand premium headphone monitoring quality. It functions as a portable headphone amplifier, a studio utility tool, or a component in a larger C.A.S.T.-based setup. Battery operation (up to 10 hours in low-power mode) makes it suitable for remote sessions or power-free environments.
