For example, if you are using only two or three inputs on your
Nº383, you may disable the unused ones so that the select knob
selects only among connectors you are actually using. For more
information on customizing your integrated amplifier in this and
other ways, please see “Customizing Your Nº383.”
3 Alphanumeric Display
This twelve-character display provides a wide range of informa-
tion concerning the operation of the Nº383. The information dis-
played depends on what the Nº383 is doing. The information dis-
played is summarized below:
normal operation the selected input name and volume setting
balance direction and magnitude of balance offset
setup setup menus and settings
In addition, this display will indicate any known fault conditions.
For example, it will also inform you if the amplifier section has
shut down due to the presence of DC offset at the input or the
output. For more detailed information on the preamplifier’s use
of this display, please refer to the following section on the use of
the balance button, as well as the section on “Customizing Your
Nº383.”
4 Polarity Indicator
The polarity (sometimes inaccurately called “absolute phase”) of
the output of the Nº383 may be inverted via the Nº383 remote
control, in which case the red LED under the word polarity
(within the display window) will light as confirmation. A second
press of the polarity button on the remote control will restore the
polarity of the output to its original, non-inverted state.
5 Volume Knob
This control is normally used to adjust the listening volume, and
does not effect the level of the signal being sent to the record out-
put
. When in balance mode, this knob is used to vary the relative
output of the Left and Right channels. It is also used during setup
for various adjustments; see “Customization of your Nº383.”
