Single desk mounting kits consist of a pair of angled base plates that mount
under the lower front and rear cover screws of a single unit to raise and to tilt it
for easy use. In addition, one or more sets of vertical stacking plates, mounting to
the upper front and rear cover screws of the bottom unit, allow multiple units to
be stacked. Several units can be desk mounted side-by-side and even stacked
side-by-side using horizontal joiner kits together with mounting base and stacker
kits. P/N20617-501 is the angled base kit. P/N20617-502 is the base plus one
stacker kit (two high). P/N20617-503 is the base plus two stackers (three high).
P/N20617-504 is the stacker kit by itself and P/N20604-504 is a horizontal joiner
kit.
OPTIONS
230VAC OPERATION
The WA100-2 tabletop power supply accepts 230VAC/50-60Hz via an IEC320
male 3 pin AC input connector. User supplies a matching line cord for the local
power system.
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 (PH48-1) can boost the phantom power up to 48VDC.
MAINTENANCE
There is no routine maintenance required by 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.
