Using Simultaneous Battery and External Power Supply
Both the battery and external power supply can be connected to N22H at the same time without
causing any damage to the internal circuitry - just like a guitar pedal. The Power Inlet [11] takes
priority when connected to the mains and the internal battery will not drain when mains power is
connected.
If you’re operating with both Battery and External power supplies connected, when the Power
Inlet [11] is removed, N22H will default back to Battery power seamlessly without any drop out of
audio. The Power Inlet can then be reconnected and N22H will switch back to using external
power without any drop out of audio.
Note:
N22H does not support trickle-charging of rechargeable 9v batteries when installed.
Rechargeable batteries will need to be removed in order to be charged.
