Internal Settings
A. Microphone phantom power setting
While most applications will work well with dynamic microphones, on certain occasions the use of a
condenser microphone may be required. To supply the necessary voltage to the microphone, the
ZPR2620 provides an internal option to activate phentom power for the Microphones MIC1 and
MIC2. Open the unit and locate the rear PCB as shown below. Set the jumper as required.
B. Microphone emergency setting
In the case of an external emergency signal muting the unit’s outputs, an internal jumper can be set
to either mute the connected microphones (”off” as well or to to keep them active (so that aside of a
emergency message broadcasted, additional instructions can be given by a local microphone - “on”).
To make the setting, locate and set the jumper on the front PCB as show below.
