Radial Engineering ProMS2
October 21, 2013
Single-channel mic splitter
The RadialProMS2 is completely passive and 100 percent discrete. The engine inside is an Eclipse ET-MS10 transformer that is linear from 20Hz to 20kHz while exhibiting less than 0.01 percent distortion at 20Hz. The Eclipse transformer is equipped with a mu-metal can that shields the sensitive circuit from outside electro-magnetic fields. The microphone input features a 30dB pad to enable extra high-level sources to be used without fear of saturating the transformer. There are three outputs: The first is a direct-coupled output normally connected to the main FOH PA system mixer and provides a return path for 48V phantom should a condenser mic or active DI box be in use. The second is a transformer-isolated output particularly adept at eliminating the hum and buzz caused by ground loops. The third is a direct output with a ground lift switch. This auxiliary output can be used to feed the stage monitors, recording system or remote broadcast truck.
