FORMAT-A TWISTED PAIR
Models D-TPS3A, DB-TPS3A, DS-TPS3A
Format-A Three-Pair Senders
STEP 1: Set the MIC gain switch to NORM (normal gain) unless consistently low mic level signals are expected. Set the MIC gain switch to HIGH
if low levels are always expected. Note: If both normal and low level mic signals are expected, the gain should be set to NORM to avoid clipping
when high levels are connected.
STEP 2: Connect 24 Vdc to the power input terminals if this module is not being powered through the twisted pair cable from another module, or if
this module is located an excessive distance from the next powered module on the cable. Note: The front-panel power LED will be illuminated if
this module is powered. If this module is powering other modules through the cable and if there is a wiring short, the short must be cleared then
power must be turned off to this module for 10 seconds to reset the internal protection circuit.
STEP 3: Connect the twisted pair cable(s) and fasten the module in its mounting box.
