Battery Low Indicator [7]
The Battery Low indicator [7] offers a visual indication of
internal operating voltage. The LED lights up red when
the internal voltage drops below 6.8v.
With some batteries, it is possible that the LED may
flicker when the voltage is on the 6.8v threshold.
The Battery Low Indicator can also light up when N22H is
powered by an external 9v power source via the Power
Inlet [11] and the voltage requirements of the connected
headphones are too great. In these circumstances,
reducing the volume will prevent the power rails
dropping and improve sonic performance.
Note:
Actual remaining battery performance once the Battery Low Indicator is lit up may
vary depending on the battery type being used and its voltage performance. Some 9v
batteries can drop quickly below 6.8v and remain in use for a long time, whilst others
can stay above 6.8v for extended periods and then drop suddenly. Please see our
for more information on real-world battery tests.
Power Indicator [8]
The Power Indicator [8] lights Blue when N22H is Powered On and ready for use.
When N22H is powered via an external power source via the Power Inlet [11], the Power Indicator
will light up indicating N22H is Powered On until the Power supply is switched off.
When N22H is powered via an internal 9v Battery, the Power Indicator will light up Blue indicating
N22H is Powered On only when headphones are inserted into the Headphones Output [2]. The
Power Indicator will turn off when headphones are removed from the Headphones Output.
