OPERATIONAL NOTES

SWITCHING ON

The power switch is located on the right hand corner of the front panel. Flip the switch up to turn on

the unit and down to turn off the unit.

GAIN ADJUSTMENT

Your Langevin preamplifier has been factory calibrated for optimal gain of 15 dB in the line stage.

Should you need to change the gain, we recommend using quality test equipment which should

include an oscillator, VTTM, oscilloscope, or suitable DMM. You will find the blue internal gain

adjust potentiometers located on the prited circuit board inside the unit, one for each channel.
