volume, and the up/down arrows select 32 steps incrementally,
indicated on the display as 0 - 31. A more traditional knob, located
at the far right of the front panel, which is always active, exactly
duplicates this control function.
The next mode to the right is the input selector, for inputs 1
through 4. Input 4 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 logically control selections of
the various inputs to the preamplifier.
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 has three iterations of brightness 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 4 and has two positions selected with
the up/down arrows. The up arrow toggles to a straight through
function with neither attenuation nor gain. This function is useful
in that it allows the preamplifier to function as a unity buffer for use
with components that best function with their own volume controls,
such as surround processors. When the right-front and left-front
outputs of the processor are routed through input 4 of the X2.5
(with the gain of the X2.5 set for Unity gain), the volume will be
under full control of the processor and the X2.5’s action will be
totally transparent. When the user chooses Unity this sets the X2.5’s
gain to the low (+4dB) setting, regardless of how it was previously
configured. When at Unity both left and right level controls
on the X2.5 will have a displayed value of 24, and any previous
balance settings will be lost. Both of these default conditions are
intentional, and intended to make the most advantageous use of
your source electronics. You may also set any input to unity by
selecting low gain and setting the volume at 24.
Before selecting this option, it is imperative that the input device on
input number 4 has its gain set to minimum. Failure to follow this
precaution could result in a volume level intolerable to both ears
and speakers. To further protect your hearing and valuable audio
equipment, Wayne has designed this product, so that the volume
setting of the preamplifier will always revert to zero as you change
inputs. We trust that the remote control, with its four buttons that
duplicate those of the preamp front panel will enable you to quickly
select inputs and establish levels of output.
