of approximately 500 charge-discharge cycles. 
 
The DCA100 DC to DC Converter accepts inputs from 6 to 18 VDC and outputs 24VDC 
to operate a mixer from 6.0 or 7.2V camcorder Ni-Cd, belt-pack Ni-Cd packs, automotive 
12V or 12.0 to 14.4 V NP-1 batteries. The DCA100 requires a standard 4 pin XLR input 
connector from the battery source (pin 4 positive, pin 1 ground). Adapter fixtures are 
available for NP-1 type batteries, which can power a MX101 thru a DCA100 for up to 12 
hours (13.2V NiMH type). 
 
The BBU100-1, PPA-1 and DCA100 can all mount directly to the underside of the case 
or slip into the quick-change slide mounts provided with the PROK-1 protection kit or the 
ABAG-1 carry case. A NP-1 type battery and a spare can be Velcro to the inside of the 
carry case. 
 
 

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. The XP100 comes with an audio cable, P/N20612-
1, a DC cable, P/N20602-1, and an instruction book. The MX100 comes with an 
instruction book but does not come with any cables. The MX100 needs either its own 
separately ordered WA100 power supply or a DC cable, P/N20602-1 to share the supply 
of another. Make sure you have unpacked any battery packs or converters. Rack and desk 
mounting hardware may be packed in with the unit even though ordered separately. Wall 
mount power supplies must be ordered separately but may either be included in with the 
unit or shipped in their own box. The PROK- 1 and ABAG-1 are generally pre-assembled 
to the mixer if shipped direct from the factory otherwise they will be in a separate box. 

 
 
SETUP ADJUSTMENTS 

 
The following adjustments require that the mixer cover be removed and should be made 
before rack mounting or first use of the mixer. Remove the top cover by removing four 
Philips head screws (top two on each side). 

 
 
Phantom Power 

 
With a small pointy object select phantom microphone power if required by pushing ON 
the rocker type DIP switch S11 position 1 for input one (left hand switch, front rocker,
