Configuration - Optimus UMX-EA3 Operating Instructions Manual

4. CONFIGURATION

Using internal jumpers J1 to J8, we can configure the following
parameters:
• Input impedance (If the input has a transformer it must be
configured in LOW IMPEDANCE).
•
Separation of the cable shield from the circuit ground.
Each one of the two inputs incorporates a jumper that
allows separating the cable shield from the circuit ground
connection.
• PHANTOM power supply. Optional. When ordered, the
inputs may be separated to supply 24 VDC PNANTOM type
power. Model T700 transformer is used for sensitivities
between 0 dB and -20 dB. For sensitivities of -60 dB,
Transformer T752 is used along with an XLR connector for
the input.
The VOX priority control is configured via dipswitch SW200.
