1DISPLAY INTENSITY BUTTON
Cycles among four levels of brightness (including “off”) for the display, allowing adjustment for various ambient lighting conditions. When “off,” the display will turn on for a few seconds whenever a setting is changed. When used in conjunction with certain compatible Mark Levinson components, this button will control the display intensity of all linked components. (For more information, see “Linked Functions.”)
2ALPHANUMERIC DISPLAY
Provides a wide range of information concerning the operational status of the Nº38. The information displayed depends on the operating mode the Nº38 is in at any point in time. The information displayed is summarized below:
Monitor | Selected (audible) Source and Volume |
Record Select | “RECD” and Source to be recorded |
Balance | Direction and Magnitude of Offset |
In addition, when used with Mark Levinson power amplifiers that incorporate our communications link circuitry, this display is used to indicate the presence of a fault condition (if any) in the amplifier. Please refer to the owner’s manual of your amplifier for more information. For more detailed information on the preamplifier’s use of this display, see “Operational Modes.”
3MODE INDICATORS
Three LEDs give visual confirmation of the Operational Mode the Nº38 is in at any moment.
4MODE BUTTON
Cycles among the three primary Operational Modes of the Nº38: Monitor (the source being listened to); Record Select (the source being provided to the Record Outputs); and Balance (the relative volumes of the Left and Right channels). Confirmation of these
