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 input you have se-
lected and the listening volume (in decibels). The output control acts as a vol-
ume 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 ca-
sual user, however. When turned quickly by hand, the effect of the
output control
will accelerate (i.e., yield a greater change per revolution 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 flywheel), the
rate of change will decrease again. This design helps avoid accidental bumps of
the preamplifier’s Output Level knob sending potentially dangerous signal levels
to your loudspeakers.
Lastly, the corresponding buttons on the remote control behave in a similar fash-
ion 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 volume 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:
To select a different input for recording, simply press the appropriate Input Selec-
tion button while in this mode. Note that the Nº380 will not allow a recording
device to serve as its own source while monitoring itself, as this would allow po-
tentially dangerous feedback to be reproduced by the loudspeakers. (See “pro-
gramming input names” for more details.)
