The Ultimate Headphone Monitoring Tool For Tracking And Mixing
N22H is the ultimate tool for engineers and musicians looking to upgrade their headphone
monitoring with a high-quality, reference-grade headphone amplifier capable of letting any
pair of headphones shine.
N22H is a standalone, reference-quality headphone amplifier that you can use during
mixing or mastering, but with its rugged steel enclosure and compact form factor, it’s also
the ideal portable headphone amplifier that can be positioned next to the performer at the
end a single shielded Cat 5e, Cat 6, or Cat 7 cable using Cranborne Audio’s unique C.A.S.T.
system.

Reference-Quality Headphone Amplifier
Based on the same custom design found in Cranborne Audio’s renowned 500R8 interface,
N22H’s headphone amplifier achieves a flat Frequency Response from 0.8Hz to above
250kHz and ultra-low distortion (0.0009% THD+N, 100 kOhm load) allowing it to power
headphones with clean, transparent power during critical listening, mixing, and mastering.
There’s also enough power (up to 950mW per-ear) to drive headphones at high-volumes
during tracking – perfect for loud drummers!

With carefully calibrated High and Low Power Modes, N22H can be quickly optimised for
maximum performance with high-impedance over-ear headphones or low-impedance
in-ears at a flick of a switch. A custom logarithmic Headphone Level control also allows for
precise control of the headphone output without big shifts in volume during small
adjustments.

N22H can be powered using the included 9V DC power supply as well as any 3rd party 9v
DC (centre negative) guitar pedal power supply. It can also be powered using a 9v battery
for up to 10 hours of headphone amplification in Low Power Mode during tracking and
location recording where power isn’t available nearby.

Advanced Connectivity With C.A.S.T.
Using Cranborne Audio’s C.A.S.T. system, N22H can be effortlessly positioned where it is
needed using a single shielded Cat 5e, Cat 6, or Cat 7 cable. With a range of 330ft/100m,
N22H and C.A.S.T. is the ideal solution for convenient headphones distribution as well as a
connectivity hub for mic/line sources as an all-analogue, Cat 5e snake.

Cranborne Audio’s C.A.S.T. system (Cat 5 Analogue Snake Transport) distributes analogue
audio (including 48V phantom power) around studios and stages using affordable shielded
Cat 5e, Cat 6, and Cat 7 cabling – achieving the highest sonic results with the lowest cost.

Connect N22H to Cranborne Audio’s passive N22 using a single shielded Cat 5e, Cat 6, or Cat
7 cable and you can send a headphone mix directly into N22H’s headphone amplifier over a
distance of 330ft/100m. You can then connect mic/line signals directly to N22H’s combi-jack
inputs and they will travel through the same C.A.S.T. connection and arrive at N22’s XLR
outputs ready to be connected to your audio interface for recording.

If your studio is already built around a Cranborne Audio C.A.S.T. enabled device, N22H can
connect directly into their C.A.S.T. inputs or outputs and send/receive audio directly with
the device without the need for other hardware or complex analogue multicores.

A Palm-Sized Headphone Powerhouse
N22H is the perfect tool for those already building their studio around Cranborne Audio
products and looking to create an unmatched audio distribution system in their studio, but
it’s also the perfect way to get a bit of Cranborne Audio’s renowned sound into any studio in
the form of a portable and powerful reference-grade headphone amplifier.
