Reference-Grade Headphone Amplifier
Cat 5 Snake & C.A.S.T. Breakout Box
Cranborne Audio - N22H
Headphone Monitoring Made EasyThe Cranborne Audio N22H is a reference-grade headphone amplifier with advanced C.A.S.T. cable management, battery power, and switchable power modes. N22H works as a headphone amp that can be deployed right beside the musician where it is needed. Using the C.A.S.T. system, N22H can be connected on the end of a 100m (330ft) shielded Cat 5e, Cat 6, and Cat 7 cable and provide a headphone mix directly to the musician during tracking.
Based around the same custom design found in the 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 crucial listening, mixing, and mastering.
At A Glance

• Compatible with any shielded Cat 5e/Cat 6/Cat 7 cable with distances up to 100m/330ft
• Improved crosstalk performance with high-performance Cat 6 and Cat 7 (recommended)
• C.A.S.T IN RRTT Port and C.A.S.T OUT TTRR Port
• 9V Battery compartment and 9V DC Power Inlet
• Reference-quality headphone amplifier
Standalone Headphone Amplifier
More power, more clarityThe N22H works as a standalone, reference-grade headphone amplifier. Just connect the line outputs of your audio interface, guitar pedalboard, mixer, keyboard, or outboard hardware directly into to N22H's inputs, set the 'Source' switch on N22H to 'Inputs' and you are ready to use N22H for all of your heapdhone monitoring needs! Using N22H's headphone amp instead of those built-in to devices upgrades the headphone monitoring quality of your existing setup and lets you benefit from more power and higher clean volume with a wider variety of headphones.
C.A.S.T. Breakout Box
Pristine audio distributionC.A.S.T. uses a shielded Cat 5e, Cat 6, and Cat 7 cable rather than 4 XLRs to not just reduce cable clutter in your studio but also distribute audio around studios or stages using affordable, readily available network cabling and accomplish the highest sonic results as a result of their strict design standards.
Each C.A.S.T. connection on a Cranborne Audio product features unique optimisation to deliver the maximum signal integrity transmitted over shielded Cat 5, Cat 6, and Cat 7 cables for distances of up to 100m(330ft) without high-end roll-off and with very low-crosstalk.
C.A.S.T. ExpanderConnect N22H into 500R8/500ADAT's C.A.S.T. Input connectors and then mic/line sources connected to N22H’s inputs are sent directly to the interface's inputs ready for recording via C.A.S.T. Meanwhile, a stereo monitor mix generated by 500R8/500ADAT is carried down the same C.A.S.T. connection and straight into N22H’s headphone output.
Standalone Cat 5 SnakeReplace impractical and expensive analogue multicore systems by using one N22 and a N22H to send and receive balanced analogue audio between two locations. Connect N22 to your current audio interface and send a monitor mix directly to the N22H in the vocal booth using a single shielded Cat 5e, Cat 6, or Cat 7 cable cable.
Phantom Power
easy transferThe C.A.S.T. system is fully-able to transfer 48v, phantom power from a preamp to N22/N22H to power condenser microphones and DI boxes. Cat 5e, Cat 6, and Cat 7 cables are created to transfer much higher voltages and current than 48v, so one C.A.S.T. cable can easily transfer up to 4 separate phantom power lines in your studio or live space.
Phantom Power With 3rd Party Preamp
or Audio InterfaceIf you're using an audio interface or 3rd party preamp, just connect one N22 to your preamp's inputs, the other N22 to your microphone, and activate 48v on your preamp! Now you can seamlessly power and record your sources through a single C.A.S.T. connection!
Phantom Power With
500R8, 500ADAT, Camden EC2If you're using a 500R8, 500ADAT, or Camden EC2, simply connect the C.A.S.T. inputs of the device to the C.A.S.T. output of N22, engage 48v on your preamps, and you're ready to record!
Reference-Quality Headphone Amplifier
clean, transparent powerN22H's headphone amplifier is based around same custom design found in the renowned 500R8 interface. With a flat Frequency Response from 0.8Hz to above 250kHz and ultra-low distortion (0.0009% THD+N, 100 kOhm load), it can easily power headphones with clean, transparent power - perfect for critical listening, mixing, and mastering. There’s also up to 950mW per-ear of power to drive headphones at high-volumes during tracking - ideal for loud drummers!
Studio MixingStudio With carefully calibrated High and Low Power Modes, N22H can be quickly edited 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.
Location TrackingN22H 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 nearby power isn’t accessible.
