The GML 8355 is an external power supply for the GML 8200, 8302, 8304 and 9500 outboard processors. It is capable of powering two units simultaneously and is switchable between 110V and 220V.

The GML 8355 provides stringently regulated, pure and filtered power to the processors to remove any unwanted magnetic field radiation into the audio path. This external power supply removes unwanted magnetic field reaching the audio path greatly reducing noise as well as ensuring that the heat generated by the different transformers, rectifiers and regulators doesn’t produce any operational drift. It also delivers extremely wide input voltage tolerance to deliver unaltered performance even with low-quality power conditions.
