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 with the front panel knob.

The remote control may also be used to change the volume.

The Ayre K-5x’s exclusive volume control yields superlative sonic performance. Field-Effect Transistor (FET) switches combine with discrete metal-film resistors to create a volume control with crystal-clear transparency and no moving parts, along with digital accuracy and repeatability. The volume control comprises 66 individual levels, each with a step size of 1.0 dB allowing for precise selection of the desired volume setting.

When the unit is first connected to an AC power source, the volume level defaults to “11”, a relatively
