Operational Modes
The majority of time you spend with your Nº38 will be spent in the
Monitor mode. In this mode, the display indicates the alias of the input
you have selected and the listening volume (in decibels). The Output
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
Nº38 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 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 fashion when in the Monitor mode. If the Volume +/- buttons are
held for more than approximately 1.5 seconds, the Nº38 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.
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 alias 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 Selection button while in this mode. Note that the Nº38 will not
allow a recording device to serve as its own source while monitoring
itself, as this would allow potentially dangerous feedback to be
reproduced by the loudspeakers. (See “Programming Input Aliases”
for more details.)
The Record Outputs may be disconnected (or “defeated”) by
pressing the Input Selector button of the currently selected input a
second time. Doing so will toggle the Record Outputs on and off. The
