Cranborne Audio N22H
Congratulations on your purchase of N22H and thank you for selecting Cranborne Audio to be a
part of your music creation process.
There is a lot of innovative technology packed into this unassuming little box! Not only is it a
powerful, reference-grade headphone amplifier based on the same design as our 500R8 and
500ADAT interfaces, it’s also a gateway to our powerful C.A.S.T. system that simplifies and expands
the headphone monitoring capabilities of your studio.
Headphone amplifiers are often overlooked. Many of us engineers are willing to invest significant
amounts of money on the latest and greatest headphones in the hope that it could be the silver
bullet to more accurate monitoring. However, all too often, it is the headphone amplifier itself that
fails to deliver. That inability to drive ‘those’ headphones properly, will only leave you wondering,
‘what’s missing?’.
When we designed the headphone amplifier in our flagship 500R8, we quickly realised that we
had something special. It’s low distortion, high power, and frequency linear performance ‘lifted
the veil’ on any set of headphones we used with it - our customers agreed.
Whether tracking with high-impedance, over-ear headphones or low-impedance, in-ear monitors,
N22H delivers maximum performance with a flick of a switch between high and low power
modes.
For maximum flexibility, your N22H can be powered in multiple ways with the included 9V DC
power supply or any guitar pedal power supply. Optionally, a 9 volt battery will provide up to 10
hours of operation during location recording.
It doesn’t stop there. We built our C.A.S.T. system into N22H to allow it to be positioned anywhere
in your recording space using a single, shielded Cat 5e, Cat 6, or Cat 7 cable. With a range of
330ft/100m, your N22H serves as the ideal solution for convenient headphone distribution, or as a
connectivity hub for mic/line sources as an all-analogue, Cat 5e snake.
N22H is the perfect tool for those who are building their studio around Cranborne Audio products
and need an unmatched audio distribution system in their studio and It’s ideal for those looking
to get a bit of Cranborne Audio’s renowned sound into their recording workflow in the form of a
reference-quality headphone amplifier. N22H packs a powerful feature set, and the highest
quality sound for a price you may not expect. For us, it’s the perfect reflection of everything a
Cranborne Audio product should be.
We hope you enjoy using it!
