General advices Rear panel/connections

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.
