230VAC OPERATION

The WA100-2 power supply accepts 90-264VAC at 47-63Hz and is supplied with

interchangeable AC input connectors for worldwide use.

BATTERY OPERATION

Alkaline battery packs (BBU100-1), 24VDC gel cell rechargeable battery packs

(PPA-1) and a DC converter (DCA100-1) to operate from 12V belt pack, NP-1 or

auto batteries.

48VDC PHANTOM POWER (DMA103 only)

A DC converter P/N PH48-1 can boost the phantom power up to +48VDC.

There is no routine maintenance required for your NANOAMP. If you have a

problem, check panel LED indicators to assure that the units have DC power,

eliminate by substitution input and output cables, connectors, downstream

devices, DC interconnect cables and Wall Wart power supplies. If you are still

experiencing a problem, call us and ask for technical support.

POWER SUPPLY LEVELS

The recommended loaded DC input voltage range is 22VDC minimum to 32VDC

maximum over the full range of AC line voltage tolerances. The audio circuits will

continue to work with reduced headroom below 22VDC but the phantom

microphone power will drop out of regulation.

OPERATING POINTS

An internal reference voltage equal to 1/2 the supply voltage is generated. All

audio stage IC inputs and outputs should show a DC level equal to this voltage

when measured with a high impedance meter. Audio inputs and outputs are

capacitor coupled and ground referenced.
