The FET switches used in the input selector circuitry offer transparent, noise-free switching, with no moving parts. Please be aware that they can be overloaded if the output voltage from the source component is too high. Do not use a source component that has an output level greater than4VRMS unbalanced, or 8 V RMS balanced. Using a source component with too great an output level will cause distortion.

Controls and Operation At the heart of the Ayre K-5x’s control system is a sophisticated microprocessor. This microprocessor is normally “asleep” and all digital systems are turned off, including the master clock. When the microprocessor receives a command, either from the front panel or the remote control, it “wakes up” to execute the command, and then immediately returns to “sleep” mode. This system ensures noise-free reproduction of music signals. Volume Control The volume level is changed Th

Processor Pass-Through When using the Ayre K-5x in a surround-sound system for home theater, it is desirable to use the “Processor Pass-Through” mode. This mode allows your two-channel music sources to be routed directly through the K-5x, avoiding the sonic degradation of most processors, and at the same time allows the front two channels of the theater system to integrate with the K-5x with the touch of a single button. If you are using a surround-sound processor, connect the front left and rig

The chosen input is now programmed for “Processor Pass-Through” operation, disabling the now redundant volume control of the K-5x. When that input is selected, the preamplifier section of the K-5x is set to unity gain (0 dB), and the volume is controlled directly from the surround-sound processor. The volume indicator of the K-5x will display “PP” to show that the “Processor Pass-Through” mode has been selected for that input. To clear the “Processor Pass-Through” mode from an input and restore
