MULTIPLE CLEAR-COM BELTPACK CHANNELS FROM
ONE POWER SUPPLY
A single two-output power supply can provide power for more than two
CCI-22 party-line channels. In this case the power supply provides
power for each party-line, but each CCI-22 channel provides the
termination for each party-line. Many Clear-Com power supplies have
a switch to enable or disable the termination circuits from each of its
outputs. If using such a supply:
1. Disable the terminations by using the switch.
2. Connect the PS-702 output to all of the CCI-22 channels to be
powered using the standard three connections in the XLR
connector.
