Balanced Analog

Volume Control

State-of-the-Art

Output Buffer

Rather than use the digital attenuator on-board the DAC, the Nº390S incorporates a fully balanced analog volume control similar to that found in Mark Levinson separate preamplifiers. When activated (by turning on the variable output function under setup: sound), the output of the Nº390S may be attenuated in precise 0.1dB steps through most of the range. Significantly, the Nº390S maintains the full performance of its remarkable DACs at all volume levels—something impossible with digital volume controls, regardless of what techniques may be employed to mask the sonic consequences of this design approach.

The balanced discrete output buffer circuitry used in the Nº390S employs the same topology used in the remarkable Mark Levinson Nº32 Reference Preamplifier. A hallmark of Mark Levinson preamplifier and digital processor design, this circuit has proven itself time and time again to be both sonically transparent and exceptionally immune to adverse interactions with interconnecting cables and unusual input impedance characteristics of power amplifiers or preamplifiers. The Nº390S features a new, ultra compact, implementation of the Mark Levinson output buffer circuit pushing noise coupling and parasitic effects to vanishingly small levels. This exceptionally robust output stage allows the Nº390S to make the most of what whatever combination of preamplifier, power amplifier, or cables you choose to use.

Front Panel, Nº390S

1. display intensity

Pressing this button varies the brightness of the display. Four brightness levels are available, including “display off.” All other front panel LEDs change their brightness levels appropriately, except that they remain at the dimmest level when the display itself is off.

When power is first applied to the Nº390S (or when power is restored after an interruption), the display is automatically set to its highest level.

Pressing the display intensity button once dims the display one level; pressing it again turns the display off; pressing display intensity once more returns the display to its brightest level; pressing it a fourth time will return it to medium. (If other Mark Levinson components in the system are “Linked” to the Nº390S, all display intensities can change in unison. See Special Functions for more information.)

If the display is set to “off,” pressing any key will cause it to light at medium intensity for approximately four seconds in order to display the action of the key press.
