If volume could be somewhat softer (in order to improve volume control
range e.g.), push the switch labelled "-6dB" (half gain) or "-12dB"
(quarter gain) in upward direction.
If you find your HPA V90 should provide more gain, do so with the
switch labelled "+6 dB" (double gain) or "+12 dB" (quadruple gain).
Ex-factory, all switches are set to their lowest position - i.e. 0 dB or unity
gain - which should be sufficient for most applications.
OPERATION
Most control elements and indicators are located on the front panel.
POWER SWITCH
The unit is put into operation by means of the power switch. Power-on
status is indicated by the blue LED below.
