control buttons, indicated by up arrows (^) and down (v) arrows.
Above the volume controls are two vertical arrays of 4 LEDs each.
This indicator is likely different from what you are accustomed to.
We think you will appreciate how easy it is to read from a distance.
The left most LED array is decade and the right most array is range.
Associated with the volume control is one additional light and a
function control button labeled as “MUTE”. In the very lowest
volume setting there will be no output and the “Mute” indicator
light will be lit. Immediately to the left of the lit “MUTE” indicator
the lowermost LED in the range column will also be lit. None of
the decade LED’s will be lit, at this time. As you step the volume
upward using the up (^) button additional LED’s in the range column
will light and the mute LED will extinguish. When you reach the top
of the range, the first decade LED will become illuminated, and the
range LED will drop back to its lowest indicated setting. And so it
goes; think of this as a counting system in base 5.
Activating “MUTE” while at any volume level does not lose the
chosen volume setting. When deactivating mute the X2.2 will be
returned to the last stored volume level.
Should you wish to upgrade the 2.2’s status to a full function remote
control preamplifier, this may be acomplished at the factory. With
additional circuitry and new front panel the X2.2 may be turned
into an X2.5 This upgrade adds an informative vacuum fluorescent
display, balance control, display brightness, mono, unity function,
gain setting and remote control capability.
A rear mounted pair of five-way binding posts are intended to
control the on/off function of our own X series power amplifiers
from the X2.2 front panel. This function is activated through
software by simultaneously pushing the extreme left control button
(INPUT) and the extreme right (MUTE) control button. When
the preamp mode “Amp” is selected it allows the user to switch
a nominal 12 volts DC at maximum draw of 50 milliamps to the
rear panel red and black five-way binding posts. In some instances
this voltage may have the ability to control products from other
manufacturers, but we by no means have comprehensive listing of
their compatible features. If you have questions about compatibility
your service technician and dealer are an excellent source of
information. For connection to other Pass Labs products please
consult the owner’s manual for specific instructions.
The electronic volume control allows approximately 60 dB range. In
this manner tracking of the volume of the two balanced channels is
possible with accuracy unavailable on any ordinary volume control,
