PALMER PMT09 is a 1 into 2 microphone level split transformer. PCB09 is made to accept 4 pcs. PMT09. It is designed to allow 2 transformer isolated and one parallel output. The parallel output is needed to link the +48V phantom power. Connect Link Out with the microphone input of the mixing console that will deliver the phantom power, usually the FOH desk. To avoid the total loss of signal when one output is shorted space for decoupling resistors is provided. These resistors shall be metal film 1% types.
