USE AS A MICROPHONE PREAMPLIFIER
Set the input switch in the Mic position. For proper calibration input gain
should be placed to gain control at -20db and the control Output in the
position indicated by a small arrow where distortion remains below 0.1%. Then
turn up the gain control until the signal has a maximum level, but without
audible distortion (which is very evident in your ear when present). Once the
Gain is set, if it´s necessary, the Output control can be varied to modify the
output signal.
RECORDING ELECTRIC INSTRUMENTS (electric guitars, electro-
acoustic, basses, ...)
Connect the instrument to the female jacks on the front panel, place the switch
in the Mic position (not the Line), set the output key in the position indicated by
a small arrow, and adjust the necessary gain. It is important to have the switch
in the mic position because in this manner the output will give us a good level
without raising too much Gain.
The +48V Phantom Power is not present in the front jacks in any possible
combination of switches, to prevent damage to the instruments.
In the case of connecting electric keyboards or sound modules, it is advisable
to place the switch in the Line position due to their high level output.
