Operational Modes
the monitor mode The majority of time you spend with your Nº380 will be spent in the
monitor mode. In this mode, the display indicates the name of the in-
put you have selected and the listening volume (in decibels). The out-
put control acts as a volume knob, increasing or decreasing the volume
in 0.1 dB increments above 39.0 (with gradually increasing increments
below this low level). The
input selection buttons select the source to
be listened to at any point in time. In short, in the
monitor mode, the
Nº380 acts precisely as you would expect a preamplifier to act.
There are several refinements which may not be immediately apparent
to the casual user, however. When turned quickly by hand, the effect of
the output control will accelerate (i.e., yield a greater change per revo-
lution of the knob) so as to reach your preferred volume more quickly.
Conversely, when the knob is turned slowly, the volume changes at
maximum resolution to facilitate fine adjustments and precise level
control (0.1 dB through most of the range).
However, if the volume knob is spun quickly (as though it were a fly-
wheel), the rate of change will decrease again. This design helps avoid
accidental bumps of the preamplifier’s Output Level knob sending po-
tentially dangerous signal levels to your loudspeakers.
Lastly, the corresponding buttons on the remote control behave in a
similar fashion when in the monitor mode. If the volume +/- buttons
are held for more than approximately 1.5 seconds, the Nº380 infers that
you would like to change volume more quickly and accelerates the vol-
ume change.
While in the monitor mode, the input selector buttons choose the
source which will be heard over the loudspeakers.
the record select mode When you wish to send a signal out to be recorded, push the mode
button once to enter the record select mode. In this mode, the display
indicates “RECD” on the left side and the name of the input currently
being supplied to the Record Outputs on the right. An example is given
below:
