Dateq BCS70 Manual
BCS71(GE) dual mono input module
9
Phantom power supply
Non-dynamic microphones usually need a 48V external pow er supply. If this pow er has to be
supplied by the BCS70, place jumper P7 in the ‘ON’ position. +48VDC (related to the (0)-input)
will be supplied to both the (+) and the (-) input.
Jumper P7 is positioned next to the bus connector of the BCS71(GE) module. The factory
default for this jumper is ‘OFF’.
Warning: central muting of multiple microphone channels
To prevent the line1/line2-selection of the input-modules from malfunctioning, pins #14
(common Cue / Cough) of the input-connectors can not be connected to each other. When
using a system that mutes multiple microphone channels with the ‘cough’-input (like FlexCom
FXS-D extensions), please note that if this system uses a common ground (like the FXS-D),
don’t connect this ground to pin #14 (common Cue / Cough), but rather use #13 (Frame) or
#25 (Ground).
