CRANBORNE AUDIO N22H Headphone Amplifier and C.A.S.T. Breakout Box

Accurate headphone monitoring is critical for tracking, mixing and recording, especially when musicians and equipment are spread across multiple rooms or locations. The Cranborne Audio N22H headphone amplifier and C.A.S.T. breakout box combines reference-grade headphone amplification with flexible analog audio distribution in a compact, portable design. Derived from the headphone amplifier architecture found in Cranborne Audio's 500R8 interface, the N22H delivers a ruler-flat frequency response from 0.8Hz to beyond 250kHz, ultra-low distortion and up to 950mW of output power per channel. Integrated C.A.S.T. technology further expands its capabilities by allowing analog audio and headphone signals to travel over Cat 5e, Cat 6 or Cat 7 cable, providing a streamlined solution for studio, live sound, broadcast and location-recording workflows.

Reference-Grade Headphone Monitoring

The N22H is engineered to provide transparent, detailed monitoring that reveals the nuances of a performance or mix. Its reference-grade amplifier design delivers a frequency response extending from 0.8Hz to above 250kHz with ultra-low distortion, helping preserve clarity across the audible spectrum. With up to 950mW of output power available per channel, the N22H can confidently drive a wide range of headphones, from sensitive in-ear monitors to demanding high-impedance studio models. High and low power operating modes further optimize performance for different monitoring applications, giving engineers and musicians greater flexibility when selecting headphones.

Expand Audio Distribution With C.A.S.T.

More than a headphone amplifier, the N22H also functions as a C.A.S.T. breakout box, extending analog audio and monitoring capabilities over readily available Cat 5e, Cat 6 or Cat 7 cable. When integrated into a compatible C.A.S.T. system, it can distribute audio signals up to 330' from the source, simplifying connections between control rooms, live rooms, stages and remote recording locations. This approach reduces cable clutter while providing a convenient way to route headphone mixes and analog audio throughout a production environment. For studios already using Cranborne Audio products, the N22H serves as a flexible expansion point within the broader C.A.S.T. ecosystem.

Portable Performance for Modern Workflows

Designed for use in the studio, on location or anywhere reliable monitoring is required, the N22H combines professional performance with practical portability. Its compact form factor is easy to transport and deploy, while optional 9V battery operation allows monitoring in situations where traditional power sources may be unavailable. Whether serving as a standalone headphone amplifier, a remote monitoring station or part of a larger C.A.S.T.-enabled system, the Cranborne Audio N22H delivers accurate monitoring and flexible analog audio distribution for modern production environments.
