The DA103 and DMA103 require 22 to 30VDC and are designed to share a
common external 24VDC "Wall Wart" type power supply, included with each unit.
A pair of loop-thru DC connectors on the rear of each module permits several
units to be daisy-chained with P/N 20602-1 DC power loop-thru cables to a single
power supply. The WA100-1 and WA100-2 (universal 90-264VAC, available at
extra charge) are 400mA supplies. The DA103 and DMA103 both draw about
100mA at full output. Any combination, which adds up to less than the supply
rating, can be powered by a single supply.
INSTALLATION
UNPACKING
Inspect the equipment. Shake it to see if anything is rattling around inside. If
there is any visible damage to the unit or to the box it came in, contact the factory
but do not return anything to ATI without prior authorization and shipping
instructions. It may be necessary to have the shipping company inspect the unit
and the box at your location. Count the pieces! Don't throw out the boxes and
packing material until you are sure you have everything that is coming to you.
NANOAMPS need either their own WA100 power supply or a DC cable, P/N
20602-1 to share the supply of another NANOAMP.
Rack and desk mounting hardware may be packed in with the unit even though
ordered separately.
WIRING
AUDIO CONNECTIONS
DMA103 - balanced XLR type inputs and outputs are wired with pin 2 as HI and
pin 3 as LOW. Pin 1 is the cable shield and ground connection.
DA103 - line level audio connections are made to the Phoenix type two-piece
connectors (Hi - Lo - Shield) using the rear label as a guide. Connectors separate
with a straight pull toward the rear. Strip the wires cleanly without nicking, clamp
them in the plug by tightening the screws and reinsert the plug into the
receptacle.
Active balanced outputs and inputs require a reference ground connection to the
source or receiving device for proper operation. This ground can be provided by
the rack frame or a studio ground bus connection if the cable shield does not
carry it through.
