Audio Inputs
The audio inputs are two 3-pin female XLR connectors located in the area
labeled Audio IN, L and R being the left and right channels respectively.
When using the active mode on the PS15TD only the Left channel XLR
connector is used. Signal is applied between pins 2 and 3, pin 1 is
connected to ground. When the Controller is linked to a signal source with
balanced outputs, the XLR connections are simply wired pin to pin (1 to 1,
etc.). As a result of the balanced nature of the outputs (and providing that
balancing is respected by way of the connection to the amplifier), there is
no hot or cold pin - the PS TDcontroller being neutral regarding the
polarity of the signal.
In cases where an unbalanced source is connected to the inputs, the
connections should be made as follows to preserve signal polarity:
• If the amplifiers connected to the outputs of the PS TDcontroller are wired pin 3 hot, connect the hot pin of
the source to pin 3 of the Audio input XLR of the PS TDcontroller.
• If the amplifiers are wired pin 2 hot, connect the hot pin of the source to pin 2 of the Audio input XLR.
In both cases the unused signal pin (2 or 3 respectively) should be linked to pin 1 (grounded).
Audio Outputs
The audio outputs are the three 3-pin male XLRs located
in the area labeled Audio OUT. The channel
corresponding to each output connector is identified by the
labels Syst L (left channel), Syst R (right channel), and Sub
L+R (mono Sub-bass).
