X2.2 Owner’s Manual
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.

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,
