Sound Performance Lab Gain Station 2272 - Manual (Page 9)

GainStation 1 9
Again, while the GainStation 1‘s housing is EMV-proof and
protects against HF-interference, placement of the unit is very
important since it amplifies microphone signals as well as other
unwanted signals. Before connecting the GainStation 1 or any
other equipment turn off all power.
IMPORTANT: Adjust the voltage setting on the back so that it
corresponds with the power conditions.
The following graph shows the correct wiring for connecting
unbalanced signals to the balanced XLR connectors:
The HI-Z/Line Input connector is designed for unbalanced
signals only.
The TRS output connector (see „Analog Outputs“, page 10) can
be operated both with balanced and unbalanced wiring. Simply
use a mono 1/4" plug for unbalanced operation.
