User manual

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.”
