Appendix B DC Power Information
DC Power Options
Because the CB1H/CB1F Systems operate on DC
power, users have the option to run off any
user
supplied
12-volt DC power source, such as a
battery set, car-lighter adapter, etc., (provided they
use the proper cabling). Magma offers an optional 6-
foot long battery cable (CBLCB1XLR) for use with CB1
systems. The cable provides connection to the CB1 chassis on one
end, and includes a 4-pin Male XLR connector on the other end, which
fits the majority of 12-volt professional battery packs.
This cable may be purchased directly from Magma for use with the
CB1H or CB1F. Please visit our web site at
www.magma.com
for more
information.
The CB1H/CB1F is designed to accommodate DC input in the range 9-
16 VDC (the most common voltages for batteries in this industry), and
draw a maximum load of 45 Watts. Please use this information when
consulting with your local audio/video supplier when reviewing battery
options, and sizing.
