Phantom Power
-1-24 volts DC on pins 2 and 3 of LO-Z IN connector; pin 1 is common.
(Note: If Phantom Power exists at the LO-Z OUT connector of the BBE 401 and is greater than the -F 24 volts DC already
present at the LO-Z IN connector, it will automatically be fed through to the LO-Z IN connector allowing the use of a
condenser microphone that requires larger voltage, typically -
f 48 volts DC.)

Calibration Procedure for the BBE'*' Model 401
For serial numbers CXXXXX
Equipment Required:
1. DVM (digital voltmeter).
2. Signal source (audio frequencies, sine wave).
3. Low impedance, balanced source (input and output for LO-Z).
Initial Settings:
1. Definition control (VR3) to minimum.
2. LO CONTOUR (VR7), VR@ and VR5 to their middle positions.
3. GAIN (VR1) to maximum.
4. Function button IN and POWER on.
