CONFIGURATION TABLES
CONDENSER AND ELECTRET TYPE MICROPHONES
Condenser and Electret Microphones require a DC Operating
Voltage. The Amplifier provides this operating voltage or Phantom
Power selectively on Inputs.1-3-4.
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 = 18 Volt DC
Input Impedance = 250 to 600 ohm
