Cranborne Audio N22H Headphone Amplifier and C.A.S.T. Breakout Box

The Cranborne Audio N22H headphone amplifier and C.A.S.T. breakout box is a compact, high-performance headphone amp that doubles as a Cat 5 audio snake breakout point, delivering reference-grade monitoring flexibility anywhere in the studio or on location. At the heart of the N22H is a fully discrete headphone amplifier with a frequency response of 0.8Hz to above 250kHz, ultra-low distortion of just 0.0009% THD+N, and an output impedance of 0.33 ohms — giving it exceptional control and accuracy across virtually any headphone load. Calibrated High and Low Power modes let engineers optimise output for high-impedance over-ear headphones or sensitive low-impedance in-ears, delivering up to 950mW per channel into 100 ohm loads. In addition, Cranborne Audio’s C.A.S.T. (Cranborne Audio Signal Transport) system allows audio to be distributed over affordable Cat 5 cable for up to 100 metres without signal degradation, making the N22H ideal for running headphone feeds to a live room, vocal booth, or remote location. Marshall Music South Africa stocks the Cranborne Audio N22H headphone amplifier and C.A.S.T. breakout box for studios across South Africa needing flexible, high-quality headphone monitoring without long cable runs.

Portable Power and Studio Flexibility From the Cranborne Audio N22H Headphone Amplifier and C.A.S.T. Breakout Box

Whether you’re running a cue mix to a vocalist in a live room 50 metres away or providing a dedicated headphone feed on a remote recording session, the Cranborne Audio N22H headphone amplifier and C.A.S.T. breakout box is built for the task. Two balanced XLR/¼” combo inputs and two ¼” TRS outputs handle standard studio connectivity, while the C.A.S.T. input and output connect the unit directly into any Cranborne Audio C.A.S.T.-equipped system via a single Cat 5 cable. However, the N22H also runs entirely off a standard 9V battery for up to 10 hours in Low Power mode, making it one of the most portable reference headphone amplifiers available for location recording. Marshall Music South Africa recommends the Cranborne Audio N22H headphone amplifier and C.A.S.T. breakout box to South African engineers and producers who need a reliable, high-performance monitoring solution both in the studio and on the go.

Cranborne Audio

Founded in the UK in 2017 and launched at the 2018 NAMM Show, Cranborne Audio set out to bring a “modern approach to vintage sound” to project, large-format, and home studios. The name nods to Cranborne House, the former Soundcraft headquarters where the founders first worked together — and that pro-console heritage shows up throughout the range. Cranborne’s products pair transparent, high-headroom analog signal paths with switchable Mojo saturation circuits, letting engineers dial in vintage colour on demand rather than being stuck with it.
