The Whirlwind SP1X3 mic splitter provides one direct and two transformer isolated output from a mic level input. Each transformer isolated output on these devices features a ground lift switch. On the IMP Splitters are male XLR jacks, one female XLR jack and one switch as outlined below.
INPUT
Female XLR input jack for connection of a low impedance balanced signal such as that of a microphone.
DIRECT OUTPUT and ISOLATED OUTPUT
Male XLR jacks. The DIRECT OUTPUT is a straight through connection from the input jack and will pass phantom power. The ISOLATED outputs each provide a low impedance (150 Ohms) balanced output signal through a Whirlwind TRSP transformer and WILL NOT pass phantom power.
GND/LIFT OUT 1
Disconnects the ground between the input and the output when set to the LIFT position. Ground remains connected when set to the GND position. The DIRECT OUTPUT always has a connected ground.
