Description of Operation

X0.2 Owner’s Manual

In application the X 0.2’s front panel controls and alphanumeric display are quite straight forward, and intuitive. We encourage you to become familiar with their operation prior to establishing any input connections with this unit. Experience indicates that engaging in a few minutes of exploration and playtime will add much to your ultimate enjoyment of this exceptional Pass Labs product.

The two front panel mode switches move the pre-amplifier and its display through 9 different functions. From virtual left to virtual right these functions are as follows: Volume, Input, Mute, Tape, Balance, Display, Mono, Unity, Amp (power-amplifier turn on/off control). Actuating the mode < switch moves the function to the feature immediately to the virtual left, and conversely actuating the mode > switch moves the function to the feature that is immediately to the virtual right.

The two Select switches (designated by up and down pointing arrows) then alter the displayed active function. The select arrows toggle the following functions either off or on (the up pointing arrow ^ representing “on” and the down pointing arrow v representing “off ”) Mute, Tape, Mono, and Amp.

The leftmost function as selected by the two mode switches is volume, and the up/down arrows select 72 steps incrementally, indicated on the fluorescent display as 0 - 71. A more traditional knob, located at the far right of the front panel, which is always active, exactly duplicates this control function. Each step is approximately 1 dB of incremental change.

The next mode to the right is the input selector, for inputs 1 through

5.Input 5 is unique in that it is linked with the Unity function. (The UNITY FUNCTION is discussed at length later in this manual.) The two select arrows (^ & v) logically control selections of the various inputs to the pre-amplifier.

The channel balance function is affected by the up and down arrows. The up arrow is balance right and the down arrow conversely balance left.

The display function chooses one of three iterations of brightness for the front panel fluorescent display. These choices of display brightness are selectable by the up/down arrows; they are bright, dim and off.

The unity function bears special attention. This control is associated only with input number 5 and has two positions selected with the
