INPUT CONNECTIONS
MICROPHONE INPUT PHANTOM POWER
CONDENSER AND ELECTRET TYPE MICROPHONES
Condenser and Electret Microphones require a DC Operating
Voltage. Paso Amplifiers provide this operating voltage or Phantom
Power selectively on the Microphone Input.
Prior to selecting the Condenser or Electret Microphone be sure
that the Operating Voltage and Output Impedance of the device
match the Input characteristics of the Amplifier listed below.
Phantom Power = 16 Volt DC
Input Impedance = 250 to 600 ohm
ACCESS TO PHANTOM POWER SELECTOR
1)
Remove Power Cord from AC Outlet.
2) Remove the three screws on each side of the Amplifier and
the three screws located on the Rear Panel Top securing the
Top Cover to the Chassis.
3) Lift Cover and carefully slide Cover out towards the rear.
4) Locate the Preamplifier Printed Board No. 3130-2 attached
to the rear panel and behind the Inputs Terminal Strip.

shown on Fig. 7A locate the Selector Jumper marked
PHANTOM.
The Jumper Socket is marked as follows:
JP4
= ON - OFF - PHANTOM
To turn the Phantom Power On, re-position the
Jumper to the ON POSITION (JP 4).
To change the Selector position lift the Mini Shorting
Plug out of the socket pins and re-position as desired.
Make sure the Mini Plug is lined up with the socket
pins.
THE FOLLOWING INSTRUCTIONS REQUIRE THE REMOVAL OF THE AMPLIFIER PROTECTIVE COVER AND ARE
