AB GND and ACD GND ground switches
In the mode one input/four outputs (Y IN/ABCD OUT).
The AB GND and ACD GND grounds switches enable to set the grounds connections in
the way that eliminates ground loops occurring or to connect the grounds in order to
eliminate hums and switching noises. In order the device works properly always use the
A output at first (the A connector should always be used as the first one) The amp
connected to A output should posses the connection between the signal ground and
grounding wire. If all of amps posses the connection between the signal ground and
grounding the AB GND and ACD GND switches should be set to OFF position. If to the
given output is connected an amp without connection between signal ground and
grounding the ground switch of this output should be set to ON. The AB GND switch
connects the A output ground with B output ground and the ACD GND switch connects
the A output ground with the C and D outputs ground.
