decreases its value; and is also balance left. If any control is used the display reverts to the last saved output level, therefore we suggest you reduce the volume before switching inputs.

The remote control uses the same four-button protocol, though it is physically arranged slightly different than the X1’s front panel. The far left button “<” is mode left and the far right button “>” is mode right. The top button “^” is select up, and the bottom button “v” is select down. The display shows the active function, just as it would when using the front panel controls. The display has two brightness levels and off, selected by the up “^” and down “v” buttons when the mode “display” is visible.

The electronic volume control allows greater than 60 dB range and is driven by a microcontroller that reads an optical encoder that serves as a front panel volume control. In this manner tracking of the volume of the two balanced channels is possible with accuracy unavailable on any ordinary volume control, assuring precise level steps and high common mode rejection in balanced circuits.

Wayne has included some unique features on the X1 that give it unprecedented versatility.

At the extreme virtual right of the mode selection is the function labeled “gain”. This control allows you, the user to adjust the gain of the X1 to extract the best possible performance out of a variety of source components of different manufacturers. The “Low Gain” setting allows for 4 dB of gain from the X1 and the “Hi Gain” allows for 14 dB of gain. The 10 dB difference between these two settings require that you pay attention to volume as you switch back and forth between High and Low Gain. With a number of products one setting may convey a greater sense of musicality than the other. Let your ears be the final arbiter. With our own X series amplifiers which are quite high gain (30 dB), we find the +4 dB setting to be most satisfying.

The unity function too 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 X1 (with the gain of the X1 set for Unity gain), the volume will be under full control of the processor and the X1’s action will be
