Warning:
N22H’s Headphone Output is extremely loud! Prolonged
exposure to loud music can cause permanent hearing loss.
Please exercise caution when using N22H and reduce the
Headphones Level Control [1] when listening for long periods of
time.

[1] Headphones Level Control: Adjusts the
volume of the headphones output.
[8] Power Indicator: Lights Blue when N22H
is Powered On via battery or mains power.
[2] Headphones Output: Used for
connecting headphones to N22H. When
using battery power, N22H automatically
powers on when headphones are connected
to this ¼” jack.
[9] Battery Cover/Battery Compartment:
Removable cover for the 9V battery
compartment and Power Mode switch.
Note: Only 9V batteries should be used.
[3] Outputs: Balanced, TRS outputs of the
C.A.S.T. RR paths. These Outputs are passive
and do not require power to operate.
[10] Power Mode Switch: Switches the
headphone output between Low and High
Power modes.
Note: Only switch Power Modes when
N22H is Powered Off.
[4] Inputs: Combi jack inputs for connecting
audio to the C.A.S.T. TT paths. Also used for
connecting stereo playback during
standalone operation. These analogue Inputs
send audio into the C.A.S.T. TT ports passively
and do not require power to operate.
[11] Power Inlet: Powers N22H’s headphone
output using the supplied 9V DC power
supply. Battery is disconnected internally
when power inlet is being used.
Note: When power inlet is used, N22H stays
Powered On.
[5] Width Switch: Adjusts the Width of the
headphones output between true Stereo or
Mono.
[12] C.A.S.T. IN: Used to connect N22H to the
C.A.S.T. Output of another C.A.S.T.-enabled
device.
Note: The C.A.S.T. IN port is covered using a
Cat5 plug. Only remove this plug when
N22H is to be used with a C.A.S.T. OUT of
another device.
[6] Source Switch: Selects the input source
of N22H’s headphone amplifier between the
C.A.S.T. connections [12/13] and Inputs 1-2 [4]
for standalone operation.
[13] C.A.S.T. OUT: Used to connect N22H to
the C.A.S.T. IN of another C.A.S.T.-enabled
device.
[7] Battery Low Indicator: Lights Red when
internal power drops below 6.8v.
Note: Duration between LED lighting Red
and unit powering off will vary from
battery to battery and headphones being
used.
[14] Mic Stand Mount: ⅜” thread mount
used to fix N22H onto a mic stand or bracket.
Note: For mic stands with a larger thread,
a 5/8" male to 3/8" female screw thread
adapter should be used.
Package Contents
So now your N22H is out of it’s packaging, you’re probably itching to get it

-Quickstart Guide
Power Modes
N22H features two selectable
power modes that are designed
to optimise N22H’s headphone
output for maximum
performance with
high-impedance and
low-impedance headphones.
Low Power Mode
Low Power Mode optimises N22H to achieve the longest battery life and
optimum volume range when using low impedance in-ear (IEM) and
over-ear headphones. When engaged, N22H’s current consumption is
approximately 30mA idle (80mA peak) and you can achieve ~8+ hours of
battery life.
High Power Mode
High Power Mode optimises N22H to achieve the highest headroom and
maximum volume when using high impedance headphones. When
engaged, N22H’s current consumption is approximately 110mA idle (390mA
peak) and you can achieve ~2 hours of battery life.
Note:
Actual battery life will vary depending on battery type being
used, headphone impedance/sensitivity, source material and it’s
frequency content, as well as overall headphone volume.

Hardware Setup: C.A.S.T.
This hardware setup diagram will get N22H connected within a
C.A.S.T.-enabled system:
1) Connect N22H’s C.A.S.T. Output [13] to the C.A.S.T. Input of another
C.A.S.T.-enabled device using shielded Cat 5e, Cat 6, or Cat 7 cable.
2) Connect balanced Mic/Line sources to the combi jack inputs [4] of
N22H.
3) Select the ‘C.A.S.T.’ input option using the Source Switch [6].
4) Select the appropriate Power Mode using the Power Mode switch
[10].
5) Connect headphones to N22H’s headphone output [2].
i) If using battery power, the unit will power on automatically
when headphones are connected.
ii) If using mains power, N22H powers on automatically when
power is detected.
Once connected, mic/line sources connected to N22H will travel through the
C.A.S.T. connection and arrive at the inputs of the device for processing
whilst the mix created on the other C.A.S.T. device travels directly to N22H’s
headphone output for monitoring. Adjust headphone level [1] to taste.

Hardware Setup: Standalone Mode
This hardware setup diagram will get N22H configured as a standalone,
reference-quality headphone amp:
1) Connect your stereo playback source from an audio interface or
similar into N22H’s combi jack inputs [4].
i) For best performance, ensure that the playback source is a
line-level output from an audio interface or preamp.
2) Select the ‘Inputs’ option using the Source Switch [6].
3) Select the appropriate Power Mode using the Power Mode switch
[10].
4) Connect headphones to N22H’s headphone output [2].
i) If using battery power, the unit will power on automatically
when headphones are connected.
ii) If using mains power, N22H powers on automatically when
power is detected.
Once connected, stereo line sources passed into N22H’s inputs will be sent
directly through to the headphone amplifier for monitoring. Adjust
headphone level [1] to taste.
